1. Earthquakes cause violent ruptures of the earth
We all know the scenario from movies, the hero’s try and escape the rupture from the earth. The crack keeps running all the way up to the hero’s foot where it suddenly stops. This common misconception arises since when movies need to be more spectacular.
In fact, earthquakes tremble the earth for up to multiple minutes based on the severity of the earthquake. Earthquakes do not cause earth ruptures as illustrated by an AI below in meme 1.
Thus you shouldn’t be afraid that the earth will split underneath you during an earthquake.
2. It is better to run outside than staying inside during an earthquake
Often times people believe that running outside during an earthquake is safer than staying inside.
By going outside you risk being hit by falling debris, rubble and subduction zones while if you stay inside the building most likely will absorb the earthquake shaking.
It is therefore better to seek shelter inside sheltering yourself from above by hiding underneath tables, beds or sturdy furniture.
This way you are protected by the solidly built walls and ceilings of the building while simultaneously ensuring you are safe from falling books, chest of drawers, fridges, wardrobes and book shelf’s.
3. Earthquakes are predictable events
Unlike most other natural phenomena which we have extensively researched, the predictability of earthquakes still remain a resounding problem in science and engineering.
Top tier researchers still struggle with methodologies and theories to explain and provide early warning systems for earthquakes.
Typically sounding equipment is placed on locations around the globe, allowing the triangulation of epicenters to be calculated.

4. Earthquakes only happen during warm weather
In ancient greek, they believed that earthquakes were mystical events caused on warm sunny days where the earth opened up underneath their feet and closed again later on, see reference for more information.
Unlike the ancient Greeks, people today have a misconception that earthquakes happen during warm sunny weather.
Although this would be convenient allowing us to better estimate the eminent occurrence of an earthquake, sadly this isn’t the case.
Earthquakes are driven by deep earth dynamics governed by mass and heat transfers indifferent to top-earth weather phenomena.
Thus earthquakes can happen during sunny, rainy, snowy, foggy or stormy weather indifferent to other phenomena’s driving mechanisms.

5. The initial shaking is defining a marked ending to the earthquake
A common misconception about earthquakes is that once the initial shaking stops the earthquake is over. This is however not the case. As aftershocks of earthquakes always accompanies the initial shaking and the higher on the Richter scale the earthquake is, the larger and long-lasting the aftershocks become.

This means that the danger after the initial shaking recedes unfortunately still resides. The dangerous aftershocks are critical to be vary off, since the initial shaking can loosen and damage buildings while the aftershocks cause weakened structures to collapse or loose debris to fall down on people below.
The Richter scale and aftershocks
The power of the aftershocks and the initial shaking follows a logarithmic scale naturally distributing with powers of 10 in magnitude. This scale, called the ‘Richter scale’ is widely used to describe the severity of experienced earthquakes, see Figure 1 as an example. This scale defines the magnitude of the initial shaking and also defines the aftershocks strengths.
In order to understand the distribution of aftershocks researchers have compared the temporal extent of the number of observed aftershocks with number of days since the main shaking event, see Figure 2. They have found that the distribution of aftershocks with number of shaking events follow an exponentially declining function with time since main shock.
6. Earthquakes only happen in Japan and USA
Another common misconception about Earthquakes is that they only happen at specific locations around the earth such as Japan and USA.
One of the driving mechanisms behind earthquakes is plate tectonics. Plate tectonics is theoretical framework that is the movement of continents and countries located on drifting (large timescale) plates at different parts of the world.
By indexing the world in tectonic sections each within its own plate see Figure 3. It is possible to explain most of the historic movements of continents throughout earth eras and develop theories for the occurrences of earthquakes whose likelihood depends on the locations of fault-lines of the different types such as subduction, lateral sliding and spreading.
The Western Mediterranean – a new example
As a newer example lets take a closer look at the interesting fault-lines which are the located at the Western Mediterranean towards the Gibraltar strait. This area is interesting because of the differences within the topographic and bathymetric features clearly shown in Figure 4.
Figure 4 and 5 include locations and markings of fault-lines together with recorded magnitude earthquakes. Arrows show the measured movement of the tectonic plates given as a yearly movement in mm’s. Corresponding to roughly 4.5 mm’s per year for the North African continental crust.
7. Drills can negate earthquake damages
To battle the damages of earthquakes we incorporate drills that explain to children that they should run for cover and hide underneath tables. This way of providing false hope to children can be dangerous if not correctly addressed.
Knowing when to run outside and when to seek cover inside is important as a means of preventing human injury during an earthquake. The damaging forces from earthquakes are not influenced by people running away from them.
In order to mitigate the damaging effects of earthquakes it is therefore necessary to continuously invest sturdier building materials, equipment and tuned mass dampers for high-risers. Such that buildings resistance towards the damaging shaking of earthquakes are continuously improving.
Preemptive investments are key to ensure that future disastrous events are accounted for and mitigated as much as possible.
Related read: Effective climate adaptation strategies
The drills are an important supplement which allow people to react quickly in the event of an earthquake. This must be accompanied by smart investment decisions enhancing the existing building mass for everyone benefit.
8. Building codes == safe buildings
Strict building codes lead to safer buildings. This is a common misconception present across the globe.
In fact, the foundation for safe buildings is strict building codes mixed with the efficient quality assurance. High-quality building work with proper quality control, safe building environments and senior-staff controlling junior is key.
The senior staff must check work carried out by junior laborer, allowing for the detection of faults and errors early on in the building process. The early detection of errors is critical for ensuring high-quality work and consequently safe buildings according to the strict building codes.
9. The implications of earthquakes are local
The effects of earthquakes can cause other dangerous events such as Tsunamis. Implications of earthquakes and the resulting consequences of their generated Tsunamis are dangerous and possibly globally covered.
The Tsunamis can spread from epicenters across the globe causing massive damages all because of earthquakes are displacing large amounts of water.
The damages on energy infrastructure such as nuclear powerplants can potentially damage the environment of the entire globe. These powerplants are vulnerable to earthquakes happening in the vicinity. History tells us that nuclear waste as a result of earthquake disasters can spread across the globe and pose a real threat for the environment and the people living in it.
10. Earthquakes are all the same
A common misconception about earthquakes is that all of them are the same in the fact that they are developing similarly across the globe regardless of the fault line types.
This is incorrect since earthquakes are dynamic phenomena whose development depend on the different instances of the boundary conditions as well as the soils initial state before the shaking starts.
The marginal effects of earthquakes are essentially changing with the initial state of the soil, plate tectonics and recent geological activity. These effects are difficult if not impossible to accurate describe throughout the three-dimensional medium.
Geophysical surveys make it easier to try and estimate tectonic plate composition. The survey depths of intrusion are however sufficiently deep to fully explain the plate tectonic behavior.
Bonus: Earthquakes can change the length of a day
In fact earthquakes are not only powerful destructive events, they can actually (in theory) change the length of a day on earth.
By releasing an increasing amount of energy through the shaking events, it is possible for the most powerful earthquakes to change earths rotation and thus the length of a day.

The ramp from Northbound Dallas North Tollway to eastbound Interstate 635 will be closed through Aug. 20 for complete reconstruction as part of the LBJ Express project.
The five-week ramp closure, which began July 14, will allow the direct-connector ramp to be rebuilt all at once rather than staging construction that would have required 11 full-weekend closures. This schedule shoul allow the new ramp to open before classes resume for the new school year.
Crews are re-constructing the I-635 bridge over the Dallas North Tollway and portions of the connecting ramps within the interchange. Closures of the Tollway are planned and scheduled occasionally to accommodate the work. Whenever they are possible, closures occur at night and on weekends during off-peak hours whenever possible.


At the AASHTO Committee on Safety Meeting in April 2022, Tim Kerns and Vivian Berra Figuereo of the Maryland Department of Transportation reported on a speed management demonstration project in Bishopville, Maryland. The project was funded by a grant from GHSA, the Insurance Institute for Highway Safety (IIHS), and the National Road Safety Foundation (NRSF).
The project combined enforcement, engineering, and public outreach, resulting in a 9% decrease in average speeds. During the demonstration project, the odds that a vehicle was speeding dropped by three-quarters. Afterward, the odds of speeding were 37% lower than before the program began.
The decrease in average speeds was credited to a holistic, multi-pronged approach of education, engineering, and enforcement.
IIHS Senior Research Transportation Engineer Wen Hu, the lead author of the study, said, “We believe efforts must be sustained in order to succeed over the long term and reduce speed-related crashes and fatalities.”

The regulation of the temperature, as well as the quality of indoor air are vital elements for the comfort and productivity of the human being in commercial, business and academic buildings. However, the requirements ensuring an optimal efficiency of the building resources require high levels of energy consumption.
This is why, work is currently under way to build controlled ventilation systems to minimize energy loss without affecting the quality of indoor air. In general, energy consumption in ventilation system is due to two factors: loss in energy when expelling indoor air and the energy consumed by the machinery responsible for the airflow.
EC Motors: the efficient alternative
Engineers, architects, and scientists are working around the world to reduce our dependence to air-conditioning systems with high energy consumption, with the introduction of new technologies.
It is the case for the use of EC motors, a external rotor motor with electronic confutation, brushes and controlled by a microprocessor, which in comparison with traditional motors running on alternating current systems, works independently form the tension or the power supply frequency, bringing a more efficient operational capacity saving up to a 70% of energy.
This is why, ZONAIR3D, always up to speed on the latest technologies, has equipped most of its purification systems with EC motors. Appart from the savings in energy, EC motors are known for their low noise level, helping our customers reach optimal comfort levels.

Aalborg CSP has just received the certificate for its PTES technology, a Technology Qualification Certificate which proves that the PTES technology and unique lid solution fulfills the requirements for design and functionality. Among other things this include a minimum lifetime of 25 years, a minimum energy loss and an availability factor of 100% without risk of stoppages. Moreover, a minimum 90% of all materials used in a PTES are recyclable.
Throughout the past years, low-temperature heat storage investments have been made to, among other things, further develop, optimize, and commercialize the complete PTES technology including the insulating lid cover. The latest achievements in improving the insulated PTES lid cover have further matured the PTES technology making it a bankable investment for utility companies worldwide.
Investments in energy infrastructure around storage of excess heating and low-temperature energy is an important building block in the sector-coupling and provides municipalities and energy operations companies with the necessary flexibility as a response to the increasing electrification of our society. Without flexibility, we become much too dependent on a volatile electricity market, which can cause significant variations in the heating cost from the utility companies, states Svante Bundgaard, CEO at Aalborg CSP.
Special lid technology creates long lifetime and high availability
Historically, the PTES lid technology has caused technical issues, un-wanted thermal losses and in worst case breakdowns. The now certified insulating lid from Aalborg CSP was developed with the purpose of creating a commercial and well-documented solution that would address key issues experienced during previous deployment of PTES projects. The lid technology addresses and solves issues related to water accumulation inside the lid, water ponding on top of the lid, air accumulation below the lid and thermal expansion. It controls internal vapor, external rainfall and has an automatic ventilation system that prevents air from accumulating inside the PTES.
Regardless of the types of materials or design solutions used, it has resulted in issues with the insulation ability and durability as well as a significant number of unexpected manual operations and maintenance hours each week to avoid water reservoirs on top of the PTES – or even worse, hidden inside the insulation layers. At Marstal Fjernvarme the newly installed PTES lid is replacing a defect and older generation lid and based on this Marstal Fjernvarme has gained a full-automatic plant which requires a minimum of maintenance and supervision. Likewise, the heat loss from the PTES has been reduced, thereby increasing the efficiency of the overall energy system.
To validate the technology, Lloyd’s Register has inspected the project site in Marstal as well as reviewed and evaluated all technical solutions, critical components, and calculations. Moreover, performance tests from Marstal have been reviewed to confirm the functional performance, durability, and quality of the PTES lid technology. All specifications, such as the 25-year service life, the maximum heat loss of 10% and the 90% recyclability have thus been checked and verified by Lloyd’s Register.
Low-cost storage technology enables commercialization of PTES technology
The certification was issued shortly after Aalborg CSP received an order for an 11,000 m2 customized lid solution for the 70,000 m3 Integrated PTES system in Høje Taastrup near Copenhagen, Denmark. The PTES in Høje Taastrup is a thermal storage functioning as a thermal battery with a capacity of 3,300 MWh. The thermal battery is charged by heat from the transmission grid and discharged to the district heating network when the demand for heating increases. The lid solution from Aalborg CSP will ensure a lower heat loss inside the PTES resulting in higher performance and reliability of the storage.
The PTES technology has great opportunities and several projects within 200,000 to 1,000,000 m3 have already been identified in what is considered a promising pipeline within the European countries; this, despite the fact that the technology is still not implemented in many countries. However, with the new design concepts, a technology qualification certification and a large-scale commercial project already implemented, the PTES technology will be a key element in the energy infrastructure development in the years to come.


Case Study: Oval House, Brixton
As renowned experts in supplying state of the art access control systems, our team were asked to submit prices for speed lane barrier solutions to IFSE, who were fit-out contractors to both reception and bar/kitchen facilities for Oval House in Brixton. The project and all works were under the instruction of the project’s main contractor, Galliford Try.
After consultation with both the lead architect of the project in addition to the client, the PG300 range of barriers were identified as the optimal solution.
Quick and efficient barrier installation
Our team ordered PG300 range of barriers in addition to a reception desk control station. The sleek appearance of the barriers ensured that the reception desk position and access was maintained.
Various site visits were made during the duration of the project, and our engineers issued an installation site programme that was increased due to both Covid and delays and the availability of materials.
We also supplied product floor fixing templates to the site in order to accurately enable the cable entry location to be identified. It was then agreed that all services would be basement fed to avoid existing installed cable routes.
Retail Associates installation team worked with the supervision of site electrical contractors and fire alarm integrators, to ensure all works were completed and commissioned over a two day period. Installation was undertaken and completed early December 2021, site opening is planned for early 2022.

More and more customers nowadays, who would like to establish skyscrapers, find it also required to think about a lift. It is indicated by the fact that establishing a new building without implementing above mentioned solution is analyzed to be making it not be as functional as possible. Consequently, if we would like to build a wonderful skyscraper that would serve considerable amount of people for many years, we are advised to also think about sufficient lifting equipment. It is referred to the fact that owing to it we might allow people to travel rapider in the vertical perspective as well as avoid situation in which we would get tired with walking upstairs.
On the other side, if we would like to think about similar solution like a lift, we ought to to also not forget about safety issues. It is implied by the fact that anytime this kind lift would break down, there is a substantial risk that something is possible to happen to the health of the people that are travelling with them.
Another crucial factor that has to be checked by ourselves in the topic of grounding a big building is that these days picking them is considered to be one of the most popular trends.
It is referred to the fact that having more vertical than horizontal orientation and concentrating on building taller buildings we are possible to save significant amount of money. Nonetheless, there also is considerable amount of details like for instance interior side of a lift, which means that lifting equipment can certainly support us substantially make it look really attractively.
As it has already been mentioned in the title, Poland is with no doubt one of those countries that can offer us almost uncountable amount of benefits and attractive alternatives in the topic of making the lifts be more efficient as well as attractive. That’s the reason why, such goods like for instance lifting equipment offered by Polish enterprises is likely to surely awake our interest as well as help us substantially realize our goal of establishing a skyscraper that would be wonderful as well as functional.

The Federal Emergency Management Agency (FEMA) is pleased to announce the release of Rapid Observation of Vulnerability and Estimation of Risk (ROVER), fast, free, mobile software for pre- and post-earthquake building safety screening.
ROVER has been successfully pilot tested in Salt Lake City by the Utah Seismic Safety Commission and the Structural Engineers Association of Utah and by the Los Angeles Unified School District. ROVER automates two de facto international standard paper-based seismic safety screening procedures: FEMA P-154, Rapid Visual Screening (RVS) of Buildings for Potential Seismic Hazards, and ATC-20, Post earthquake Safety Evaluation of Buildings.
ROVER’s pre-earthquake module is used by field inspectors to quickly compile an electronic inventory of buildings, record important seismic features of a building, and generate an automatic estimate of the need for detailed seismic evaluation. ROVER’s post-earthquake module is used to quickly perform and manage the safety tagging (red, yellow, and green tags) almost universally applied to buildings after earthquakes.
Highlights of the new ROVER software include:
- One-time data entry to a built-in database Captures data via digital photos
- Determines building geolocation
- Exports to Google Earth for mapping
- Imports pre-existing data
- Speeds post-earthquake safety assessment by accessing pre-earthquake data
- Allows for remote management of screening
- Optionally integrates with USGS ShakeCast for seismic monitoring of buildings and with FEMA’s HAZUS-MH to estimate future building repair costs, casualties, and loss of use
The ROVER Server is capable of operating as an online service for the ROVER smartphone client and also a web site for direct access by any web browser. The web site service has also been optimized for the small screens found on a smartphone or on any Internet-connected tablet.
ROVER was designed and developed for FEMA by ATC, SPA Risk LLC, and Instrumental Software Technologies, Inc. The ROVER Development Partners will maintain a user-support web page. FEMA will continue to play an important role in implementation and outreach to NEHRP customers.

Can interactive urban landscapes elucidate natural processes that are invisible but present in cities?
Can technology built into urban form become a medium for translation, allowing environmental information imperceptible by our own sensory apparatus to be rendered legible?
How can architecture activate public space in order to inform its occupants of the intangible water quality of the Gowanus Canal?
Tubeflation is a reactive pedestrian bridge that informs the Gowanus community about the water quality of the canal via dynamic, participatory inflation and deflation operations.
For decades the Gowanus Canal saw heavy use and abuse as a major shipping and industrial center for South Brooklyn. Now the majority of the heavy industry has moved elsewhere and the neighborhood has blossomed as a vibrant residential and commercial district. New York City has begun to re-vitalize and re-claim much of its previously inhabitable waterfront. The Gowanus Canal is no exception to this new trend to “re-green” the waterfront of post-industrial zones in order to create new parks and public spaces.
Our proposed intervention is located on the threshold between the burgeoning Gowanus art and cultural scene and the remnants of the industrial heritage of the canal. Tubeflation responds to the historic fabric of the neighborhood and reflects on how the area will develop. The hypothesis addresses the rehabilitation of two separate lots, combining the post-industrial, dilapidated site of a former Iron Mill and the newly constructed Whole Foods supermarket. It engages the site at the architectural, social and ecological levels, emphasizing the integration a new public realm and addressing the emergent notion of urban ecology.
With the manufacturing processes that surrounded the canal, there was an overflow of chemical waste and still today there are efforts of restoring the canal’s purity. As storm water fills the streets and municipal sewage systems, the exhaust of waste enters the canal. Integrating and understanding the topography of the site our system collects water from regions more prone to storm water run-off, and acting as a preliminary filtration system pumps it to inflatable pools along the pedestrian paths. These paths will span an inlet of the Gowanus, connecting land masses- which in the future may be used by the new incoming residents and workers of the Gowanus neighborhood. As more storm water fills these pools, the surrounding walkways inflate with air. The walkable surfaces will distort to a different elevation, creating landscaped relationships between the community and the active filtration pools.
As more storm water fills these pools, a sensor will dictate the psi the system will inflate to, but will not inflate until a proximity sensor is broken. The proximity sensor will not control the entire system, rather it will control the inflatables within a radius of 30 feet. The inflation of the nearby surroundings of the occupant will engulf them, causing the storm water runoff data-driven output of inflation to encapsulate the occupants .
Tubeflation is an intervention that promotes reciprocity and a data-driven dialogue between humans, water and their shared environment. The body of water is the membrane of another ecosystem and Tubeflation is set to create awareness of its multi-layered impact and to spark conversations by contributing to a display of collective interest in the river ecosystem.

January 19th of this year will mark the 70th birthday of the now-departed legendary singer, Janis Joplin. May 27th of this year will mark the 76th anniversary of the opening of the Golden Gate Bridge. How are these two events related?
The last echoes of the 75th Anniversary Celebration of the opening of the Golden Gate Bridge have faded away. A talented army of volunteers, supporters and Corporate Partners came together to make a memorable event unforgettable.
25 years ago a similar mission was underway to celebrate the 50th Anniversary of the opening of the Golden Gate Bridge. A major part of that celebration was the construction of a commemorative brick walkway financed by the sales of precision inscribed paving bricks.
Unfortunately, this walkway was removed on January 18, 2012. Construction of a new Bridge Pavilion building required that current Building Codes be met and the Conservancy, with the approval of the GGB, decided to remove the 50th Anniversary Brick Walkway.
Assurances were made to the people who purchased bricks that although the bricks could not be saved, the Bridge would implement “…several alternative measures to preserve the 50th anniversary bricks by other means”.
“You can know the name of a bird in all the languages of the world, but when you’re finished, you’ll know absolutely nothing whatever about the bird… So let’s look at the bird and see what it’s doing — that’s what counts. I learned very early the difference between knowing the name of something and knowing something.” —Richard Feynman
Q: What is the difference between “Permanence” and “Lasting Recognition”?
A: 25 years.
In 1987, as part of a program to upgrade the visitor’s area at the Golden Gate Bridge, the Golden Gate Bridge District raised money by selling “precision inscribed paving bricks carrying the names of people from all over the world”. Purchased from the Golden Gate Bridge Gardens, Inc., by March 1988 a total of 7,416 bricks were installed in a new garden setting on the East side of the Toll Plaza. Continue reading
The Golden Gate Bridge 50th Anniversary Commemorative Brick walkway is now just a memory to us. I wonder what reaction future generations will have to this chapter of Bridge History.
The decision to remove the bricks has been a rather divisive one, judging from the responses I have received from the public at large. Bridge Officials say that removal of the brick pathway was necessary to meet Federal ADA requirements and opponents say those requirements could have been met and without removing the walkway. Now, more than ever, we need to put aside our differences and move on.
I have a plan…. Continue reading


Expanding one’s living space through a room addition can provide numerous benefits, including increased home value and improved functionality. However, such an undertaking demands careful planning and deliberation due to its complexity.
This article aims to shed light on the key considerations homeowners should bear in mind when contemplating an extension project for their property. It will delve into the critical aspects of planning meticulously, choosing appropriate design elements, adhering to local building regulations, and managing costs effectively.
In this era where a sense of belonging is highly appreciated, creating additional rooms in one’s residence may serve as both a practical solution for spatial needs and a means to foster closer family ties or social interactions. The process of executing these projects requires understanding of essential parameters that go beyond mere aesthetic considerations. Aspects like structural integrity, efficient utilization of space and resources, sustainable materials usage become paramount.
Let this be your guide in navigating the intricacies involved in planning for room additions with confidence and precision.
Navigating the Complexities of Home Extension Projects
Delving into the labyrinthine world of home extension projects, one must be prepared to juggle an assortment of tasks ranging from obtaining planning permissions to ensuring structural integrity, all while attempting to retain a semblance of sanity.
It is essential for homeowners to grasp the intricacies involved in such ventures. These extend beyond mere construction and design aspects and delve deeper into legalities encompassing local building codes, zoning regulations and restrictions that could potentially thwart progress.
Moreover, individuals must acquaint themselves with the necessity of securing appropriate contractor insurance coverage as well as warranties on workmanship; these aspects serve as protective barriers against unforeseen hiccups during project implementation.
Furthermore, it is worth noting that maintaining structural integrity is paramount during room addition projects. Homeowners should not overlook this crucial element which involves ensuring firm foundation supports and seamless integration with existing architectural style – both vital for overall stability and aesthetic appeal.
An understanding of basic engineering principles would be beneficial in this regard; however, consulting professional engineers or architects is highly advisable for accurate assessment and effective execution. This engagement with professionals fosters a sense of belonging among homeowners who are thus reassured that their interests are being safeguarded throughout the project’s duration.


Keynsham railway station ramp scheme moves closer
By BeckyFeather | Tuesday, March 19, 2013, 19:23
Plans are progressing for the long-awaited ramp to help people with a disability, push-chairs and heavy luggage reach the Bristol-bound platform at Keynsham railway station.
The wall to the right of the picture is the one that will be knocked down to make way for contractors' vehicles
First Great Western has asked Bath & North East Somerset Council if it can temporarily remove a wall to provide an access wide enough for construction vehicles to get in from Station Road to build the ramp.
The Department for Transport has already agreed to fund the work to build the ramp between the existing pedestrian footbridge and Platform 1, which passengers can currently only access by negotiating many steps.
A total of £465,000 has been secured to pay for the ramp to be built, including a £50,000 contribution from B&NES Council.
Disabled passengers coming from Bath and London have long complained of having to travel into Bristol, change at Temple Meads, and travel back to Keynsham in order to get off on the eastbound platform where they can exit without steps.
People are invited to comment on FGW's access plans by April 8.
Passengers will still be able to use the station while the work is carried out. It is expected to take 24 weeks and start later this year.

Roof Replacement Options for Coastal Property
For coastal residences, traditional roofing materials are usually a poor choice. Learn about six roofing materials that are popular for beach houses because of their strength and aesthetic appeal.
1. Tiles made of clay
Clay tiles are common in coastal homes because they blend in well with the Mediterranean-style architecture present in several coastal areas, such as Durban areas. They might not fit in with the aesthetic of other coastal places, like Cape Town. Clay tiles, in addition to their attractive appearance, have practical utility for coastal properties. Because they are inherently resistant to the weathering impacts of water and sea air, they are extremely long-lasting.
2. Slate Tiles No. 2
Slate is another classic roofing material that is ideal for coastal dwellings. Slate is a natural stone that comes in a wide range of colors, including neutrals like black and gray as well as more vibrant hues like green, red, and purple. Slate tiles, like clay tiles, are extremely durable and fire-resistant. Slate roofs may endure a century or more, making them one of the most durable roof materials available. Slate is a popular choice for Colonial and European-style residences, such as French chateaus, but it may also be used in luxury beach houses.
Steel is a popular material for metal roofing, utilized in a number of residences and beach houses. The materials for steel roofing are in huge sheets and can be left in a metallic color or painted or colored. Metal is cheaper than any other material that we’ve talked about, but its appearance is also somewhat different, which can look wonderful at your beach house.
Both galvanized and oxidated steel offers practical advantages, both of which can be viewed on the market today. Since the metal reflects heat naturally and does not absorb it, the roof can maintain the attic and the entire house cooler which can provide great advantages on the coast.

MANILA, Philippines – Industrial giants Hanjin and Kumho may join the bidding for the proposed P3.3 billion expansion of the Puerto Prin-cesa international airport, the Department of Transportation and Communications (DOTC) said.
DOTC Undersecretary Jose Perpetuo Lotilla issued Special Bid Bulletin No. 01–2013 containing the agency’s reply on the written queries made by Hanjin Heavy Industries Construction Co. Ltd. and Kumho Industrial Corp.
The Korean companies sought clarification on the terms of bidding of the $79.41 million design-build contract for the expansion of the Puerto Princesa airport that serves as the gateway to Palawan where the Underground River is located.
The DOTC issued an invitation to bid last Aug. 17, urging Korean companies to join the bidding for the project.
The DOTC said interested bidders have until Oct. 15 to submit their bids.
The Philippine government through the Department of Finance (DOF) received a loan worth $71.61 million from the Economic Development Cooperation Fund of the Republic of Korea coursed through the Export-Import Bank of Korea.
The Puerto Princesa airport development Project aims to improve the existing airport facilities by expanding its present capacity to meet the projected increase in air passenger and cargo demand.
The project involves the rehabilitation or improvement of the existing to meet the standards of the International Civil Aviation Organization (ICAO) through the construction of new landside facilities in the northwestern side of the existing runway such as passenger terminal building, control tower, administration building, cargo terminal building.
The project also involves the construction of a rescue and fire fighting building as well as a new apron and connecting taxiways, and upgrading of the existing 2.6 kilometer runway and its strip, and the provision of new navigational and traffic control equipment.
The Puerto Princesa Underground River was named one of the New Seven Wonders of the World and is expected to generate 1.2 million tourists by 2016 and two million tourists by 2025.
Likewise, the airport is seen to revitalize the transport and trade linkages under the Brunei Darussalam, Indonesia, Malaysia and the Philippines-East ASEAN Growth Area (BIMP EAGA).


The winter seasons are over as well as you locate that the wall surfaces and the sides between the wall surface and also the roof are looking instead shaken.

First off it takes a decision for the home to go in for the experience, then there is the issue of the cash involved as well as ultimately the look for a competent contractor. I'll take you with these actions and more. We start with why the roofing requires a repair work and also what ought to you do as a home owner when you start to believe that the roofing, which you have actually had for some time, isn't really as safe as it made use of to be. Act immediately. The failure to locate and also remedy small roof covering deterioration in the earliest phases is possibly the biggest root cause of premature roof covering troubles. This is especially real of roof materials used on relatively low-sloped roofs. The reasons of roofing damage are aplenty, and also some roofing system designs experience more degeneration as compared to others.
Roof coverings can get harmed due to exposure to duplicated wind gusts, snow, rainfall as well as flying debris. An additional root cause of roofing damages could be the material utilized while building it. The layout of the roof is one more major cause for the roof covering's wear and tear. In situation a roofing has actually been made wrongly, it will certainly experience more damage as compared to others. Defective styles might consist of a weak roof framework like deflection under lots, insufficient slope of the roofing system, drooping framework, as well as insufficient variety of drains to allow the water out, and also incompatible roof product. Other reasons include deterioration due to the components as well as a basic lack of upkeep like enabling algae to expand.
The above causes demand the owners to seek the signs and adopt fixings. The repair work procedure begins by first doing an analysis of the damages yourself.

The option of a contractor needs to be made based upon his/her credentials and also the amount of experience they has had in the sort of roof covering which decorates your residence. A number of internet sites advertise licensed roofing professionals and also it is a good idea to embrace a certified roofing professional.
After necessary examination and also study, the roofing contractor will usually offer an estimate of time and money needed for the check here repair to happen. This is the time for a major decision making process to be initiated. Court the price of fixing versus a substitute, if the condition so warrants. Typically, a knowledgeable roofing professional will suggest a combination of both. Some components of the roofing system can be changed, while some might just need repair of floor tiles, or a layer of asphalt. The decision is made based upon the monetary constraints and also the time available handy.
Roofing repair is an aware decision, and also as high as contractors may attempt and persuade you, a substitute is a problematic treatment. However, replacement is needed in times where the roof might pave the way or the leak is hefty. Think before providing approval, yet if the scenario so requires, do not hesitate. Repair work is needed, and also late fixing will set you back more to your house, your pocket as well as the general look of your home too.

UEM has provided Recycle / Reuse solutions to many of its reputed clients. These include a MBR System (Membrane Bio-Reactor) followed by UF/RO for a Minute Maid project for Coca Cola Plant in Florida. UEM was selected by Delhi Jal Board to build the sewage treatment plant of 1 MGD capacity for the Common Wealth Games Village, based on MBR technology. This plant is the largest sewage MBR in India, where the wastewater coming from Common Wealth Games Village and the neighboring Akshardham temple is being treated. Other than this, MBR has been installed for treating hotel sewage at Oberoi Udaivilas, Udaipur, tanneries etc.
For the treatment of both domestic and industrial wastewater, the use of membrane bioreactors has expanded significantly over the years. This technology serves our clients, that need effluent of consistent quality with low BOD and Total suspended solids (TSS) for reuse and discharge, for sites where space is limited, for sites where there is a need to increase the capacity of an existing system, or to reduce operating requirements. The advantages of using membrane bioreactor tanks include reduced fouling, reduced cleaning cycles, and gravity operation capability.
The MBR replaces secondary clarification in a conventional wastewater treatment plant. MBRs separate biologically treated effluent from the mixed liquor utilizing membranes to perform the separation. Typical MLSS concentrations in MBR systems are 10,000 mg/l to 12,000 mg/l. The MBR filtrate can be directly treated by RO without any need for additional pretreatment. The system is very simple to operate, with a minimum of pumps and controls and low requirements for operator attention.


The abandoned railway..

Allora Railway Station dates back to 1897 but is disused now, along with the grain sheds alongside. The old wooden sleepers are becoming badly deteriorated.
Originally called the 'Stour Valley Line', this short Suffolk branch line was briefly known as the 'The Lovejoy Line' (after a dour BBC TV series about a local antique dealer) and more recently, 'The Gainsborough Line', after the famous local artist, Thomas Gainsborough (born 1727).

The function of reverse osmosis (RO) system is to remove impurities and contaminants from water. This is achieved by applying high pressure to water, forcing it through a semi-permeable membrane. The membrane acts as a filter, retaining the contaminants on one side while allowing the purified water to pass through to the other side. This process is called reverse osmosis because it is the reverse of the natural process of osmosis, where water molecules pass through a membrane from a lower concentration to a higher concentration. RO is used in water treatment facilities, households, and industries to purify water for drinking, irrigation, and other uses.


The Rhea County Sheriff’s Department [RCSD] recently announced that a portion of Highway 68 in north Rhea County will be one lane in the coming weeks for repair.
“The Rhea County Sheriff’s Department along with [the Tennessee Department of Transportation] has received numerous questions about the status of the roadway,” RCSD Cpl. Aaron Loden said. “The sheriff’s department has a great working relationship with TDOT and has been in contact with TDOT since this roadway issue developed.”
Loden said that the sheriff’s department was recently notified that TDOT will still keep one lane open for slope repairs.
“TDOT is planning to keep one lane open with a signal at all times,” Loden said. “TDOT is still in the process of finalizing the permanent repair plan, and permanent repairs to the area should start soon. During the repairs, the road will remain open to one lane as it is currently.”
Highway 68, between Grandview and Spring City, was affected by flooding earlier this year. In February, the sheriff’s department was notified that several cracks formed in the roadway after heavy rains and flooding that affected the area.
The sheriff’s department checked the roadway and immediately made notification to TDOT.
TDOT employees arrived shortly after and began assessing the roadway condition and had to reduce the roadway down to one lane in the area.
The affected area is between Bill Cox Lane and Garland Lane, going up the mountain. Temporary traffic lights were put place in the area and message boards warning motorists to be prepared to stop were placed at the top of Grandview Mountain and Near Industrial Park Boulevard.


Designing for the Future: Exploring How Professional Liability Policies Impact the World of Engineering
In Part One of this Engineers Week article series, we focused on exploring how professional liability (PL) and owner’s protective professional indemnity (OPPI) policies can impact coverage for the insured. The following examples illustrate how such professional liability exposures can arise.
There are multiple settings where design errors can occur. The consequences are not only severe; there is also a lot of variability. The first example illustrates how the construction of a college football stadium led to significant lawsuits and problems. These types of issues can occur very frequently when companies are trying to fix an issue that resulted from an initial design error. The second example conveys the consequences of a miscalculation and notes the amount of money that can be in dispute over a simple mistake. Lastly, the third example illustrates a building collapsing in Surfside Florida due to the alleged negligence of the engineers and design teams involved. As shown, each example is its own building type, presenting different issues arising from engineers and design team mistakes.
- University of Central Florida Board of Trustees et al. v. Wharton Smith Inc et al.
Design errors at the outset of a project can lead to issues compounding over time. Working off an initial design error only increases the potential liability and severity that could arise. Essentially, it creates problems for those who are trying to fix the error after the fact. Once there is a problem from the start, it is inevitable that outside exposure will exacerbate the issue, resulting in injury and liability. Securing and executing a contract for a football stadium is an enormous endeavor, even for an engineer. A project like this takes significant investment, time, and energy to ensure that the specifics of the design are correct. However, even with valiant effort and other appropriate measures taken, there can still be a miscalculation, resulting in an engineer’s worst nightmare. In 2017, the University of Central Florida’s (“UCF) football stadium received the nickname “The Bounce house” after costly mistakes were made. The contractors and engineers who oversaw the development of the stadium were allegedly the cause of a premature wearing of the steel, resulting in more than 1,600 corrosive areas. The ten-year-old Spectrum Stadium now already contains rust on the steel beams, and degradation in certain locations. According to Sports Business Journal, the rust has affected the structural integrity of more than 80,000 square feet of the stadium. In order to resolve this issue, UCF settled for 1.4 million dollars to resolve the lawsuit.
- Merrill Iron & Steel v. Blaine Construction Corporation
A 2017 Pennsylvania case, Merrill Iron & Steel, Inc. v. Blaine Construction Corporation, involved the construction of a wastewater treatment facility. An engineering firm and subcontractors made substantial design calculation changes to the model that was originally provided, resulting in professional liability claims against the firm for five million dollars. The fabrication of the designs, along with the substantial changes resulted in allegations that the firm was not properly providing Building Information Modeling (“BIM”) services. BIM services are those that provide a digital representation of the project. These models include the design of the building along with the construction and the planning of the project.
- In re: Champlain Towers South Collapse Litigation
Another significant and tragic accident occurred in 2021 when one of the buildings in the Surfside Condominiums collapsed, resulting in death or severe injury. It was alleged that the engineers who were involved were negligent. More specifically, it was argued that the professional engineers failed to utilize due care. Supposedly, the engineers from Morabito Consultants found extensive damage to the condominium but did not warn of potential imminent danger.
Additionally, although the engineers in this example had a role in the collapse, the design team was also to blame. According to the New York Times, the foundation of the building along with an underground garage is the basis for scrutinizing the design. The foundation itself had issues involving water intrusion, and the underground parking garage had cracks and crumbling of the supports that were put in place. The New York Times also points out that there was a “severe strength deficiency” in the pool deck due to the design’s failure to comply with building codes. This disaster resulted in a settlement for one billion dollars between the families of the victims and the companies contributing to the collapse, according to CNN. Also, as reported by NPR in 2023, there are plans to construct a new building on that very site. However, family members of those individuals who died as a result of the building collapse were unhappy about the announcement of this potential new development.
Events like these do occur and are a result of the loss of money and lives. At the end of the day, engineers, contractors, and design teams are all humans, they make mistakes. It is, therefore, imperative that when a mistake does occur, there are policies, such as PL or OPPI, that are secured to help mitigate the many and varying consequences that may arise from a mistake. There are many complexities to such coverage options, so it’s necessary to fully explore the options available to your unique situation as a means to mitigate risk exposure.

The first phase of the Southport Sacramento River Early Implementation Project has been completed. The Village Parkway South project is a three-mile stretch of levee that will replace segments of South River Road and provide property access to residents before levee construction begins.
Sacramento Bank Project - South River Road
The Sacramento Bank Project was led by the U.S. Army Corps of Engineers. The project, just completed in March 2015, improved a segment of the Sacramento River west levee just south of the Stone Lock. Improvements included construction of a new setback levee, installation of a seepage cutoff wall and relocation of South River Road to the new levee. The new levee measures 2,200 feet and was estimated to cost $8,000,000.
The Rivers Early Implementation Project
West Sac Flood Protect completed this project in 2011. Construction improved the west levee of the Sacramento River near Bryte Park. The project corrected seepage and geometry deficiencies, including installation of a deep seepage cutoff wall. The levee spans 3,100 feet and provided a home for Bryte Nature Park Trail. The total cost for this project was approximately $21,000,000.
CHP Academy Early Implementation Project
This project, also led by West Sac Flood Protect, reconstructed the south levee of the Sacramento Bypass to correct seepage and geometry deficiencies, including installation of a seepage cutoff wall. Construction concluded in 2011. The project cost $11,500,000 and repaired 6,300 feet of levee.
Yolo Bypass South Project - Slip Repair #1
Levee repair and reconstruction along the Yolo Bypass south of Highway 80 was completed in 2009. The US Army Corps of Engineers led this project that included improving adjacent drainage facilities. The overall project improved 1,400 feet of levee and cost approximately $2,400,000.
Yolo Bypass Project - Slip Repair #2
2,500 feet of slip repairs were completed in 2011 to a section of the Yolo Bypass Levee north of Interstate 80/Hwy 50 along the Yolo Bypass. The US Army Corps of Engineers was the lead on this $3,500,000 project.
I Street Bridge Early Implementation Project
Constructed just downstream of the I Street Bridge in 2008, the project corrected seepage and geometry deficiencies with the levee. The 475-foot levee work included removing non-compliant vegetation as part of the US Army Corps of Engineers standards. The $1.6 million project, when completed, provided the footprint for the extension of River Walk Park, which was subsequently completed in 2009.

Your driveway and walkway both receive heavy foot and vehicular traffic day in and day out. Given that they serve such as practical purpose, it’s vital that they’re well constructed with strong and durable materials. However, it’s also crucial to consider which materials are the toughest to maintain since consistent maintenance is the key to its longevity.

Types of Driveway or Walkway Materials
Here’s a quick glance at the most common types and their pros and cons.
Concrete is a very labor-intensive material, but it is also one of the cheapest and longest-lasting. On average, a concrete driveway will last anywhere from 25 to 50 years, depending on the local weather conditions and how well it’s taken care of. Unfortunately, concrete is not environmentally friendly and isn’t one of the most aesthetically pleasing materials.
Gravel is perhaps the longest-lasting material. It sheds water in an environmentally friendly way and is very affordable, especially for those with long driveways or walkways, but it does need to be graded every few years. It can also make snow blowing or shoveling difficult as rocks get stuck in with the snow.
Asphalt tends to be cheaper than concrete and a bit more pleasing to look at, but it doesn’t last as long. On average, asphalt needs to be resealed every few years. Since it’s made from oil and petroleum products, it is not environmentally friendly.
Pavers are one of the more aesthetically pleasing materials, but they come at a higher price. Fortunately, they are typically very durable if cared for. Installation will be quite costly, and snow removal can be difficult, but they can be environmentally friendly. They will need careful routine maintenance to remain in top condition and last as long as possible.
Bricks are a fairly common walkway material and are relatively inexpensive. They’ll last about 25 years, but they do need to be pressure washed twice a year to prevent moss and algae growth. Bricks can be environmentally friendly as long as they aren’t laid with mortar and sand or gravel is used instead.
Porcelain is a modern and aesthetically pleasing solution, but it is also one of the most expensive. Porcelain pavers are less prone to algae growth and will require less maintenance than other paver types. In general, you can get away with a quick sweep and hose down.
Resin bound driveways or walkways are incredibly durable and affordable. Many resin bound aggregates are environmentally friendly and use non-toxic or organic materials. Installation is fairly easy, and maintenance is minimal, which is encouraging more and more homeowners to choose them.
Which Are the Toughest to Maintain?
Asphalt and stone pavers are the two most difficult to maintain. They will both need to be resealed every few years, and stone pavers should be pressure washed relatively often to avoid grass, moss, or algae from growing.
Gravel will need to be graded every few years, which can be quite a project, so it isn’t the easiest to maintain either. Additionally, bricks will also need to be pressure washed twice every year.
When it comes to the toughest materials to maintain, the order is typically asphalt, stone pavers, gravel, bricks, porcelain pavers, then resin bound. In certain climates, though, this order may be a little different as weather conditions vary greatly, and these materials all require varying levels of care.
There are numerous materials you can choose for your driveway or walkway, and these are some of the most common. Before you make your final decision, it’s always beneficial to consider their maintenance, so keep that in mind as you search for the best material to use.

Clemson, SC – Clemson University’s Board of Trustees approved two athletics facilities contracts and gave the University permission to negotiate a lease with the S.C. Research Authority (SCRA) for two new facilities to be built at the Clemson Research Park.
Trustees approved a proposal to negotiate a lease with SCRA to provide space for ongoing research in advanced materials. The proposal calls for SCRA to build a 57,000-square-foot research facility and a 25,000-square-foot office and electronic microscope facility at the Clemson Research Park, located off Highway 187 in Pendleton. Pending final state approval, the facilities could be completed as early as June 2003.
SCRA will lease the facilities to Clemson for an annual payment not to exceed $1.83 million, to be funded from existing University resources and external research grants. The research facility will house research in photonics and nanomaterials that is expected to generate $10 million in external funding next year.
Also among the approvals was a change order to an existing contract that will allow the University to replace the roof of Littlejohn Coliseum, a project that could add as much as $8 million to the cost of renovating the 36-year-old facility.
Already under way is a $23 million Coliseum renovation project to add an annex, improve sight lines, and enhance concessions, restrooms and other facilities. But recent inspections of steel girders in the roof indicated that flaws first detected and corrected in 1988 have reoccurred, leading University officials to recommend replacing the roof.
“After reviewing several options, we recommend a design that retains the existing look of Littlejohn, is cost effective and can be installed more quickly than some of the other design options,” said Scott Ludlow, chief business officer. “One benefit of the roof replacement is that it will make Littlejohn more versatile for events such as major concerts, because we will be able to hang equipment from the ceiling.”
Trustees agreed to a financial plan in which the University will issue $8 million in institutional bonds, which are repaid through student fees. The University budget will absorb the first $4 million of the roof costs, while the athletic department will cover remaining costs up to an additional $4 million. The funding plan does not require a fee increase.
Because the roof replacement is considered an emergency, Clemson will adjust its current construction contract rather than seek bids. However, the University will hire an independent cost estimator to ensure it receives competitive pricing. The contract also will include incentives to hold down costs and liquidated damages if the project is not finished on schedule. University officials said contractors indicate the project will be completed by January of 2003.
In other action, trustees awarded a $3.56 million construction contract for an indoor track facility to Melloul Blamey Construction, Ltd., of Greenville. The facility will include an enclosed 200-meter track, field event areas, training facilities and amenities for spectators.

When it comes to installing a patio it’s all about the base.
1. Gator Base is environmentally friendly, engineered to return water to the native soil due to the evacuation channels incorporated in the gator base. It will never leach chemicals or degrade in the native soil for over 100 years. This is our preferred method of base install. Gator Base takes the place and weight of 5″ of crushed limestone with dust base.
Gator Base Unit
- Equivalent to 288 lbs (130 kg) of crushed stone
- Replaces 6 in (15 cm) of compacted crushed stone
- Evacuates water through the channel
- Manufactured using lightweight high-density polypropylene
- Environment-friendly and 100% recyclable
- Extremely durable, will not degrade in the ground
- Designed with a tongue and groove system
- Gator Base Insulation has an R-Value of 3.6 (per inch thickness)
- Better Load Transfer
- Will significantly reduce the number of freeze and thaw cycles
2. Concrete Base– Concrete base is another highly recommended option. If you have an existing concrete patio we can do an “overlay” and use the concrete as a base. The existing concrete patio would need to be inspected by All Decked Out prior to making sure it could be used. From experience a concrete base patio’s way outlast the standard crushed limestone method. Just because you have a standard square patio, doesn’t mean we can’t add on or create new shapes. The options are endless. Concrete base patios can also be poured new and formed and shaped to your liking. If we pour a new concrete base we always anchor to the home, add footers to prevent settling and we prep the native soil.
3. Aggregate Base– This method used to be the most popular option until the Gator Base made its way to the market. This aggregate base method is ICPI approved and does take more labor to install. This also means bringing in larger equipment to do the patio and soil removal off-site, The aggregate base is 4″-6″ of crushed limestone with dust base and 1″ of bedding sand under the pavers.

A new research centre dedicated to developing technologies for the provision of geothermal sources of energy to cities has been launched in Perth.
The Western Australian Geothermal Centre of Excellence (WAGCOE) is a joint venture between CSIRO and The University of Western Australia, in conjunction with Curtin University of Technology, and supported by the WA State Government.
The Centre brings together researchers, industry, investors and government agencies to investigate how geothermal energy can be used to provide modern cities with air conditioning, power and desalinated water.
Centre Director, UWA Professor and Premier's Fellow Klaus Regenauer-Lieb, said Perth is an ideal geological setting for demonstrating and providing local geothermal energy.
"The shallow groundwater of the Perth Basin is an excellent source of low-grade heat which can be used for direct-use applications that people use every day," Professor Regenauer-Lieb said.
"By exploring for and using low-grade heat in a permeable sedimentary environment, we are addressing a previously overlooked opportunity to broaden the applications and use of geothermal energy.
Our aim is to make Perth the first geothermally cooled city in the coming decade and we are working closely with geothermal lease holders, city planners and other stakeholders to advance the geothermal industry and make this vision a reality", Professor Regenauer-Lieb said.
The Centre links 'below-ground' research with 'above-ground' development, by modelling low-to-intermediate temperature geothermal systems and delivering novel technologies for low-grade heat. Modelling is also being used to identify deeper and hotter geothermal sources including hot sedimentary aquifers and 'hot rocks'.
The Centre will also develop geothermal energy university courses and provide advice and consulting services to industry.


The National Transportation Safety Board has released an advisory regarding Meteorological Evaluation Towers (METs). These towers are installed to gather wind data from areas that may be used for wind development projects. The towers are generally less than 200 feet tall and are typically not lit or marked well.
These factors can make them difficult to see from the air and can pose a danger to helicopters during the landing and takeoff portions of flights. The towers are often temporary and are erected overnight, making them hard to track.
