(CUMMING, Ga.) – On Monday, September 18, 2017 the final section on State Route 400 northbound (SR 400) widening project will open to traffic.
Opening the final three and a half mile section between Bald Ridge Marina Road and Keith Bridge Road (SR 306) will complete the northbound side where work began in June of 2015.
“We were able to open this project up to traffic in sections which was a great way to help ease congestion.” Said Brent Cook, P.E. District Engineer in the Gainesville office.
The last leg at the northern point of SR 400 NB was opened to traffic from Keith Bridge Road (SR 306) to Browns Bridge Road (SR 369) back in the summer.
Cook added, “This project it is not a typical design bid build project, it’s an innovative design build concept, and it allows the contractor to design the project while construction is ongoing,”
Drivers will be able to get over into the new lane for the entire 14 miles on SR 400 NB for the Monday morning commute.
“The widening of State Route 400 is such an important infrastructure project for Forsyth County, and we have our residents to thank for making it happen through their approval in 2014 of the Forsyth County Transportation Bond,” said Forsyth County Commission Chairman Todd Levent. “This widening will undoubtedly improve traffic on State Route 400 and the opening of the new northbound lane in its entirety is an important milestone in this project.”
Georiga DOT does wants to remind the traveling public of the following:
- The new lane of State Route 400 Northbound, approaching SR 369 becomes a left turn lane.
- Minor concrete and striping work will continue at night and may require lane closures on the new lane Monday night between 9:00 p.m. and noon Tuesday.
Widening efforts on the southbound side of SR 400 began in May 2017 and the first four-mile section is expected to be opened by January 1, 2018.


“CBD News” has the latest information on when and where construction trucks will be travelling to the City Square area during the early works of the Melbourne Metro Rail Project.
Members from the Melbourne Metro Rail Authority (MMRA) and early works contractor John Holland told small business owners of their plans to minimise traffic disruption in an information session hosted by City Precinct and Collins Street Precinct on April 19.
John Holland is currently working at the CBD South site to remove surface artworks and the Brunetti restaurant structure before starting the demolition of the underground Westin Hotel car park.
John Holland spokesperson Vesna Newman said construction trucks were under strict timelines of when they were able to travel to and from the site.
These hours are before 7.30am, 10-11.30am, 1-2.30pm and after 6pm.
Trucks currently approach the site from the west via Collins St, enter and exit via Swanston St before turning east on Collins St.
Ms Newman said John Holland was working with Yarra Trams and VicRoads to find adequate staging for trucks to avoid traffic congestion.
“Part of our planning at the moment is looking at our staging, where our vehicles go when they’re not in the CBD because we don’t want to keep them around the corner,” she said.

In a recent article from Inhabitat.com, the city of Utrecht has built a bike path that crosses the Amsterdam-Rhine canal. Additionally, this winding and purposeful path.
From the article: "The bridge itself is approximately 360 feet and connects the old part of Utrecht with the new district Leidsche Rijn... The path leads through the green roof of a local Montessori school."
The project was designed by NEXT Architects, and opened April 3rd, 2017. They even have a nifty animation!


MKO have successfully completed the ecological services required to obtain planning permission for the construction and operation of a 30km section of a national road scheme. MKO were commissioned to complete the EIAR Biodiversity Chapter, AA Screening Report and Natura Impact Statement for the construction of a section of the N5 between Ballaghaderreen and Scramoge in Co. Roscommon. This involved the mapping of ecological constraints and assessment of the emerging preferred route corridor to minimise effects on biodiversity. The commission involved detailed and ongoing liaison with a multi-disciplinary project team to finalise the alignment of the road that was submitted for planning permission. MKO completed all the consultation, desk studies, ecological survey and assessment work necessary to inform the EIAR chapter and Natura Impact Statement and completed all reporting on this basis. MKO also gave evidence at the Oral Hearing that was undertaken in relation to the development. This scheme has now been granted planning permission by An Bord Pleanála.


Deciding on the date of a brick is a far from simple process. The very first point to remember is that bricks are regularly re-cycled; consequently bricks may well be older than the buildings that contain them. Secondly, any attempt to date British bricks stylistically must allow for regional variations; the size of pre th century bricks, and their arrangement, did not conform to any nationwide standards. If you want to date your local bricks you will have to get information specific to the county or city that you live in. Several methods of scientifically dating individual bricks have been explored. The most promising is rehydroxylation dating RHX.
High Street History: Brickwork
Britain first acquired the skills to manufacture fired clay bricks when large parts of the country became part of the Roman Empire in the 1st century AD. The bricks made by the Romans were generally wider and thinner than those today and were used in various ways, including as lacing courses in walls of rubble stonemasonry and in the construction of supporting pillars for hypocaust heating systems.
When the Romans left Britain in the 5th century, so too did brick-making, until the 12th century. Construction on this began in the 11th century, reusing materials from the Roman British town Verulamium. The earliest known use of brick manufactured in the UK after the Romans left is widely regarded as being Coggeshall Abbey in Essex, the oldest parts of the monastic buildings dating to
In this paper, we use optically stimulated luminescence (OSL) to date the brick attachments in order to understand the construction history of.
Prized for its classical appeal, durability, and low maintenance, brick is among the most desired types of exterior siding. The earliest known brick structures, dating back to BC in Turkey, featured crudely crafted blocks of clay left to dry in the hot sun until they hardened. Sun-baked bricks remained the norm until ancient Romans, around BC, began firing clay bricks in earthen kilns, which greatly increased their structural integrity. The bricks are then fired at a high temperature, resulting in strong bricks of uniform size.
Houses with thick brick walls were common in Europe from the 14th Century up until a few hundred years ago, when they were gradually replaced with wood-framed walls. Because transporting bricks over long distances was cost-prohibitive, solid brick wall construction was mainly limited to regions were bricks were manufactured and easily accessible.
Early brick wall construction in Colonial America often featured double brick walls, stacked a few inches apart, but parallel to each other, and then the gap between was filled with small rocks and rubble to create a thick wall that was strong enough to support a second story or overhead roof. As wood-framing techniques advanced in the s, and mass production of wooden timbers and studs began, solid brick wall construction declined.

Brickwork is masonry produced by a bricklayer , using bricks and mortar. Typically, rows of bricks called courses   are laid on top of one another to build up a structure such as a brick wall. Bricks may be differentiated from blocks by size. For example, in the UK a brick is defined as a unit having dimensions less than Brick is a popular medium for constructing buildings, and examples of brickwork are found through history as far back as the Bronze Age.
The fired-brick faces of the ziggurat of ancient Dur-Kurigalzu in Iraq date from around BC, and the brick buildings of ancient Mohenjo-daro in Pakistan were built around BC. These structures have survived from the Stone Age to the present day. Brick dimensions are expressed in construction or technical documents in two ways as co-ordinating dimensions and working dimensions. An example of a co-ordinating metric commonly used for bricks in the UK is as follows:   .
There are many other brick sizes worldwide, and many of them use this same co-ordinating principle. Mortar placed between bricks is also given separate names with respect to their position. Mortar placed horizontally below or top of a brick is called a bed, and mortar Placed vertically between bricks is called a perpend.
Reclaimed Brick Tiles
Bricks and concrete blocks are some of the oldest and most reliable of building products. Bricks were first used 5, years ago and were made from dirt using straw as a binder. Later bricks were made from clay and fired in a kiln to increase their durability. The history of concrete blocks dates back to ancient Greece and Rome, although they were not manufactured commercially until the early 20th century. Dating old brick and block is not a precise science, but there are a few things to look for.

As per the Building Code of Australia, non-habitable areas ie. Please be advised the Builder is not required to seal these areas and therefore falls under Homeowner Maintenance to address. To alleviate this problem may we suggest you purchase brick sealant from your local hardware store and apply accordingly to keep moisture and dampness to a minimum. These stains are not harmful and are part of the natural by-product of some bricks.
Staining may gradually dissipate on external surfaces subject to weathering or it can either be removed by proprietary brands or common caustic soda solution. Sufficient independent research on these products should be conducted before proceeding with application. As Vanadium is deemed to be outside the Builders control and no fault of workmanship, it is the Homeowners choice should they wish to address this. It is also advisable to ensure your sprinklers face away from the brickwork.
Failure to follow these measures may cause dampness to enter the home.
Bricks are so common that we hardly spare them a glance, but in areas of the country with no suitable local building stone, brick has been the most important durable building material since Roman times. Brick is still favoured as the material of choice for many new-build projects, especially housing developments. Despite being renowned for its durability, problems in brickwork can be very serious.
However, brick buildings dating back to the middle ages can still be found in some parts of England today. Up to the 16th century, brick was regarded as a.
Man has used brick for building purpose for thousands of years. Bricks date back to BC, which makes them one of the oldest known building materials. They were discovered in southern Turkey at the site of an ancient settlement around the city of Jericho. The first bricks, made in areas with warm climates, were mud bricks dried in the sun for hardening.
Ancient Egyptian bricks were made of clay mixed with straw. The evidence of this can be seen today at ruins of Harappa Buhen and Mohenjo-daro. Paintings on the tomb walls of Thebes portray Egyptian slaves mixing, tempering and carrying clay for the sun dried bricks. The greatest breakthrough came with the invention of fired brick in about 3, Bc. From this moment on, bricks could be made without the heat of sun and soon became popular in cooler climates. The Romans prefered to make their bricks in spring, then they stored them for two years before selling or using them.
They only used white or red clay to manufacture bricks. The Romans succeeded in introducing fired bricks to the entire country thanks to mobile kilns. These were bricks stamped with the mark of the legion who supervised the brick production. Roman bricks differed in size and shape from other ancient bricks as they were more commonly round, square, oblong, triangular and rectangular.
Dating buildings is important for survey reports: particularly for conservation appraisals, archaeological assessments, and for predicting age-related latent defects, such as Georgian ‘snapped-header’ walls, inter- wars ‘Regent Street Disease’, or post-war high-alumina cement concrete deterioration1. When a building is original, and typical of its period, its age can usually be judged by its external appearance alone.
Every era has its distinctive architectural styles, ranging from wavy roofs of the s, to bow-backed Georgian terraces of the s. But when a building is nondescript, atypical a folly , has been altered, extended or overclad, we need to examine its structure. Structural materials, components, and systems have varied through the ages.

Sullivan Engineering recently ran an article on the overall history of brick masonry. In that piece, we touched upon brick dating as far back as the Roman Empire. A few buildings date back to when New York was still known as New Amsterdam the change took place in Most of these buildings are either timber or stone construction. Since most of the island of Manhattan used to be covered with trees, it makes sense that timber was the first material used to build houses and stores.
The population increase in the lower portion of Manhattan in the early part of the 18 th century lead to closely packed wood structures that were threatened by potentially devastating and deadly fires.

Brick-work is so common that we don’t give it a second thought. What could be less interesting than a brick, you might think! But brickwork evolved to meet the needs of society, and over the centuries it has continually responded to changing needs, technology and fashions. The Romans had bricks, but they were very different from what we think of as a brick today. Brickwork as we know it was imported from the low countries in the middle ages.
The history told by brickwork is all around us. It is written in the buildings that you can see any day, and if you can understand the language in which it is written, you can read the buildings history. Walk around almost any town and look at the brickwork you pass. Often it can tell you something about the building and the area where it stands, about the purpose for which it was built and how that has changed over the years, and even the status of the building’s original owner.
In town centres especially, look up above the shop fronts where you can see the original fabric of the buildings, before they were mauled by the makers of gaudy modern shop fronts. Sadly, as with so much else, modern buildings are becoming homgenised, with the same bricks and the same styles being used in towns all over the country, but even so, after several decades of uninspired building, brickwork is once again being used imaginatively to help to enrich our townscapes.

This excavation found additional brick walls covering the top and sides of a rock wall, which according to historical records was built between AD and In this paper, we use optically stimulated luminescence OSL to date the brick attachments in order to understand the construction history of Songkhla City Wall. In total, eight brick samples were collected from the top five samples and the side three samples of the rock wall. All but one sample have excellent OSL properties and the exception is explained by limited burning of this particular brick during the production process, as also indicated by material properties.
The major challenge of this study was the correct reconstruction of the dose rate due to the complex situation onside and the limited documentation. Despite these limitations, our results imply that the rock wall and the bricks attached to its side are contemporaneous. Two samples dating to the latest nineteenth century may imply a later restoration phase. This is a preview of subscription content, log in to check access.

Over the last few years, household metal roofing has expanded significantly in popularity as several property owners have actually found out of its sturdiness, while others have actually concentrated on the several designs as well as shades available. However, there is still a greater number who are attempting to unwind the hints.
Tom Black, executive supervisor of the Steel Roof Covering Partnership (MRA), addresses one of the most usual inquiries most home owners have concerning metal roofing:
Why should a property owner take into consideration metal roof?
Steel roof has lots of benefits. For instance, metal roof coverings have a lower life cycle price compared to the majority of standard roofing material such as asphalt or cedar and also it can stand up to extreme weather condition such as hail, snow, high winds along with fire. It's likewise offered in many designs and shades to fit virtually any type of home.
Exactly what is the general price of a steel roof?
Steel roof coverings can originally set you back 3 to four times more than standard roof materials, however home owners ought to bear in mind that the typical asphalt or cedar roof needs substitute every 15 years. While asphalt or cedar roof coverings are at first less costly, when homeowners think about the price of a steel roof spread out over a 60-year period, metal is the clear choice.
Do steel roof coverings include service warranties?
While many superior asphalt roof coverings will last from 12 to Twenty Years, steel could last more than 60. That's why look at this site you'll find most metal roof with service warranties of concerning 50 years-- nearly four times more than the majority of other roof covering items.
Typically aren't metal roofs noisy?
Not at all. Metal roof coverings with strong sheathing and insulation control noise from rain, hail and negative weather just as well as any other roof product.
Just how does metal roofing stand up to extreme weather?
Metal roofing is one of the most durable roof covering product readily available. Whether wikipedia reference it's hail storm, snow, extreme winds and even fire, metal roofing safeguards property owners from whatever Nature can toss their means. For instance, in a hail storm, a steel roof covering's solid structure prevents damages, dings and also other damage hail storm is understood to trigger. In fact, homeowners in some locations get up to a 30 percent decrease in their house owners insurance coverage for having a metal roof covering set up.
Will metal roof help deal with the climbing expense of energy?
Among the most advantageous facets of metal roof covering is its ability to shield a home. Not just does metal roof maintain your home comfy regardless of the climate outside, but it could actually reduce cooling and home heating bills.
Will metal roof covering fit with the style of my home and also neighborhood?

Where can home owners go for more info on metal roof?
House owners can go to www.metalroofing.com to get more information concerning steel roof covering, watch the numerous designs readily available and also participate in the "Ask the Professionals" section.


The building contains seven large apartments, one per floor and each with 270 sq.m floor area and 50 sq.m of decks. The developer made the inspired decision to fit in one less floor than other neighbouring buildings of the same height. This allowed a generous stud height of 2700mm per floor with 3200mm for the top floor.
Decks and living spaces are along the wide frontage, facing north out to the harbour and hills. By tilting the kitchen, main bedroom and ensuite at 45 degrees , these rooms gain views to the sea past the side of the neighbouring building and yielded an unusual zigzag hallway.
There is a subtle geological reference in the concrete cladding on the east facade to shifting, folding, interlocking plates. Similarly the balconies relate to the harbour with their horizontality, openness, shape and tongue & groove soffits.

Practical exterior agent that effectively suppresses the losses of concrete slump
During the construction process, the collapse of concrete mixes is a common loss. In order to better avoid and reduce losses caused by concrete slumps, industrial Sodium Tripolyphosphate is widely used as an external agent. It ensures that the concrete has good water retention, liquidity, and adhesive, and at the same time, it inhibits the loss of time loss of concrete slump.
Composition of concrete mixer
The concrete mixer consists of cement, thickness, water, external agent, and mineral doping. The main role of industrial Sodium Tripolyphosphate in concrete construction is to reduce the amount of concrete water for the simultaneous unchanged concrete liquidity, thereby increasing the strength and durability of the concrete, or increasing the concrete under the same cement and water ratio. The liquidity of the concrete is improved.
Factors affecting concrete slump
The landslide of concrete is affected by various factors, including cement, mineral blending, aggregate, external dosage, environment, dynamic control in the transportation process, and adjustment of the combined ratio.
Industrial Sodium Tripolyphosphate mechanism
Sodium tripolyphosphate disintegrates the structure of concrete flocculation in the following three aspects:
1. Cement mass on the surface of electroearity.
2. Increase the sliding capacity of the solvent.
3. Increased decentralization, increased liquidity, and intensity.
Sodium tripolyphosphate’s specific role
Sodium tripolyphosphate directly generates a stable complex with CA2+ions, hindering the formation of hydrophilic products AFT, inhibiting the crystallization growth of the CH of the hydrophilic product, and delaying the hydration of C3S and C3A. With the increase of the amount of doping, the loss of the slump of concrete mixes has become significantly smaller, indicating that the Sodium Tripolyphosphate has a good inhibitory effect on the time loss of concrete slump.


Visitors travelling along Airport Boulevard will notice the gradual formation of Jewel Changi Airport’s (Jewel) iconic infrastructure as work on its distinctive glass and steel façade enters the last lap towards completion.
The entire Jewel facade is made up of more than 9,000 pieces of specially manufactured glass, close to 18,000 pieces of steel beams and over 6,000 steel nodes. The complexity of the façade installation is due in part to the sheer number of components, as well as the custom-made glass panels and steel nodes, with no single piece having the same dimensions and specifications. The entire façade will weigh more than 6,000 tonnes.
Given the unique measurements of each glass panel, the installation process warrants precise coordination to ensure that each panel is fitted into the correct ‘grid’ placement that it is planned for. Meticulous execution is also required as the glass panels are transported from the ground level to the top of the façade for the roof installation. Please refer to the Annex (attached) for more information about the façade installation.
To date, 75% of the overall construction has been completed and Jewel is on-track to open in 2019.

The fantastic buildings of at the present time, resembling huge suspension bridges, are the results of clinical rules verified throughout the new iron age of the 19th century. The e-book is anxious with a close and demanding account of the advance and alertness of these ideas (including statics and elasticity) by way of humans of outstanding expertise in utilized arithmetic and engineering. They have been, after all, quite often encouraged by means of the calls for of the railway, development growth. one of the impressive examples selected by way of the writer is Robert Stephenson's use of novel rules for the layout and erection of the Britannia tubular iron bridge over the Menai Straits. A heritage of the idea of buildings within the 19th Century is a uniquely finished account of a century of the advance of the speculation; an account which skilfully blends the personalities and the nice works and that's enlivened by way of little-known debts of friendship and controversy.

Construction specifics include: 1. Exterior walls are 8 in. unreinforced CMU with brick veneer. 2. Floor of the auditorium is several feet below grade; however, the bases of the steel columns are on a reinforced section of CMU that extends above grade. 3. Roof framing consists of deep truss girders at each column line with open web bar joists between column lines supported by the truss girders. 4). The gym was approximately 108 x 88 ft with the truss girders spanning across the 88 ft width. The roof system consists of two large truss girders that supported roof bar joists that supported a metal deck.
Roof framing was trusses with OSB roof sheathing. 4. The west-end roof was hip-shaped. 5. There was no evidence of mechanical connectors at the roof-to-wall intersections. Chapter 4 Performance of Commercial Buildings and Critical Facilities The team did not get the opportunity to closely examine any damaged commercial facilities (except for a collapsed cell tower) because many of the structures were already under control of owners’ representative or security teams on site. There were several large box-shaped stores that were dramatically damaged.
Additional life safety strategies might be required such that interior walls of the building provide protection against wind-borne debris striking the building occupants. This might require specific connections between interior walls and the roof or ceiling systems, and connections between the bottom of the interior walls and the floor and foundation systems. Additional shear walls in the interior of the building could reduce the tendency for the building to rack and/or overturn. These strategies must be developed based on the pressures generated by this event assuming the building envelope will be breached by wind-borne debris.

Most types of masonry found in walls of a building will allow water movement by capillary action, although this is usually controlled by a traditional physical damp proof course (dpc). However, many older properties do not have a dpc in the walls, so where a dpc is absent, has broken down or is damaged, rising damp will occur.
Where this is the case remedial damp proofing work is required which may include the installation of a chemical damp proof course system. Sovereign Chemicals Ltd supply a range of damp proofing treatments including, Injection Fluids and Injection Creams, along with installation equipment such as Injection Pumps and Guns.
Rising damp also introduces contaminating salts into walls and plaster which will require the plaster to be removed and replaced with specialist damp proofing materials. Sovereign also supply appropriate Renovating Plaster and Render suitable for this purpose.
All wood rots indicate a dampness problem. Damp in walls, floors and roofs must be tracked back to source and the cause of the damp treated . Rots are woodland fungi frequently found in houses and commercial buildings where dampness has entered, usually as the result of leaking gutters, downpipes, drains or roofing. They requires an initial moisture content of about 18% in wood, but Dry rot, unlike the family of Wet Rots, can spread across dry areas and across surfaces treated with wood preservatives. This ability, unique to Dry Rot, to travel outside of the damp area makes it dangerous to wood in buildings. You can treat masonry and timbers with wood preservatives to perfection, but a small pocket of Dry Rot can still be capable of emerging across the treated area looking for new timber to attack.
There are a number of species of woodworm, and the precise method of treatment will depend on which species is attacking the timber.


Another Comarch's building has been commissioned in the Special Economic Zone in Kraków. Colloquially referred to as the “seven”, the building has been constructed in the IT company's campus in Kraków's Czyżyny District. The office building has been equipped with photovoltaic panels, and the underground floors house charging stations for electric cars.
The building has five floors above the ground, and its total area is over 27,000 sq. m. Moreover, employees and visitors have been provided with an underground car park for 157 cars and 86 stands for bikes.
“In Kraków, Comarch currently employs some 3,000 staff. Until now, the employees used to occupy six buildings owned by Comarch, and in addition, we had to rent space in office buildings located in the economic zone. Now, all employees of the company's branch in Kraków work in Comarch's office buildings. Additionally, the new building has been adapted to receive trainees who will join the team during a summer holiday period” says Konrad Tarański, Vice President of the Management Board and Finance Director of Comarch.
The office part of the SSE7 building has been designed as an A-class structure, or it offers the highest standard of finishing and technical equipment. The building has been designed to care for the natural environment and ecology. Photovoltaic panels have been fitted on the roof to partially supply for the company's need for electricity.
“Photovoltaic panels installed on the building's roof are capable of generating maximum 64kW of electricity daily. Which means that by using an alternative source, we're capable of powering some 1,000 computers. Currently, some 1,200 persons work in the building, and maximally it may house 1,700 staff” says Łukasz Jastrząb, Director of the Strategy and Analysis Office at Comarch.
The building has four usable floors and one technical floor on its roof. The ground floor houses mainly conference rooms, while upper floors offer office space. All rooms have been equipped with a separate smart ventilation and air-conditioning system which at the same time is a source of heating. At night air-condition operates in a green mode, and in the morning, it warms up premises in advance up to the temperature set in the control panel.
The design has been prepared by Biuro Architektoniczne Artur Jasiński i Wspólnicy, and Budimex S.A. has been the General Contractor of the project.

Stormwater Poland, a prestigious cyclical conference, is opening its doors for the seventh time to bring together experts and enthusiasts related to climate change, economic transformation and water management issues. Scheduled for September 27 – 28, 2023, it will be held in Katowice, Poland. This time it will draw on the potential of the Upper Silesian-Zagłębów Metropolitan Area, which on the map of Poland and Europe is a special place in the face of environmental challenges.
Stormwater Poland – key issues
This year’s edition, under the theme “Adaptation with Quality,” focuses attention on global climate challenges and their local reflection, as well as the quality of water management in the Vistula-Oder watershed. The WMO State of the Climate 2022 report shows that temperatures in 2022. was 1.15°C higher than the 1850 – 1900 period, and the last eight years have been ranked among the warmest on record. Europe, and Poland in particular, is one of the fastest warming regions, which has a particular impact on the hydrological cycle and the availability of water resources.
While the challenges are global, action against them must be taken at the local level. It is necessary to intensify steps to secure the future of local communities in the context of climate change. Therefore, the first day of the conference will be devoted to adapting urban drainage systems and adjusting them to new conditions. Polish cities of various sizes will present the adaptation steps they are taking and the technologies they are using as examples of success. Also discussed will be the possibilities of financing these activities from the European Union, including the FEnIKS program.
The second day of the conference will focus on rainwater and snowmelt quality and general urban water management. The situation of the Oder River, a symbol of the negative impact of climate change on the environment, underscores the urgent need to take measures to improve urban water quality. Innovative solutions for treating rainwater and snowmelt will be presented to reduce the negative effects associated with emissions from storm overflows.
Stormwater management the topic of the next Stormwater Poland conference
Topics related to the use of rainwater as an alternative method of resource management will also be addressed. Their retention can help reduce abstraction from rivers and groundwater. Stormwater Poland will also present inspiring case studies from abroad based on modern tools for forecasting water quality and algal blooms, as well as data acquired from the space domain, including remote sensing.
Stormwater Poland 2023 virtually
The day before the conference, attend the Stormwater Poland 2023 workshop, where the importance for cities of investing in stormwater infrastructure will be discussed. Experts from the Ministry of the Environment, NFOŚiGW and NCBiR will present the available funding and application criteria. Participants will also hear about innovative solutions in water management and get tips on preparing a project for funding. This is a unique opportunity to gain valuable first-hand information and dispel doubts.
A field workshop will also be held in Gliwice, during which participants will learn details of the project “Construction of an intelligent management system for the stormwater drainage network.” They will learn how Gliwice is adapting to climate change through consistent rainwater management. During their visits to various locations, they will see new stormwater tanks, hydrological and meteorological monitoring stations and electronic information boards for residents. Together with the instructor, they will take measurements and learn modern techniques for monitoring surface water parameters. The workshop will conclude with a presentation on the benefits of a comprehensive stormwater drainage system management project.
Stormwater Poland 2023 conference a way to fight for a better future
The Stormwater Poland 2023 conference is not only a place to exchange knowledge, but above all to inspire effective action on climate change adaptation and sustainable management of water resources. The goal of the event is to make a concerted effort to protect the environment in which we live in order to pass it on to future generations in the best possible condition.
You are cordially invited to come to Katowice in September 2023. For the Stormwater Poland 2023 Conference – Adaptation with quality! Together, as a global community, we can change the world for the better and take care of our planet and future generations.

Did you know that one square foot of Architectural Fusions prevents eight pounds of waste from reaching the landfill? To put this into perspective, we recently resurfaced 216 elevator doors and frames in a Las Vegas hotel using 9,184 square feet of Fusions. This translates to keeping 73,472 pounds of construction waste out of a landfill and a huge nod toward sustainability in the world of renovations.
By choosing Architectural Fusions, you’re promoting a more sustainable project and a healthier environment. Sustainability is more than a buzzword, it’s a philosophy and way of life. During renovations, existing substrates can be reused rather than contributing more waste to the landfill, and for new construction, Fusions deliver the warmth and aesthetics of natural materials without depleting precious natural resources.


Particulars of a pin-ended column made from a 250 MPa yield steel are :
L = 1 m A = 103 mm2 I = 105 mm4 η = 0.3
What load can it support if a safety factor of 2 is specified ?
r = √(I/A) = 10 mm ρ = L/r = 100 σc = E(π/ρ)2 = 204 MPa
From ( 2) with S = 250 MPa, the direct stress at failure is σd = 134 MPa ( note that σd must be less than both σc and S ).
The failure load is therefore this mean stress times the area, A, ie. 134 kN.
So if the safety factor is 2, the permissible load will be 134/2 = 67 kN.
Let us see what would happen if this had been carried out incorrectly with safety factor applied to strength rather than to load.
From ( 2) with S = Sy /n = 250/2 = 125 MPa, the direct stress is found to be 83 MPa. Multiplying by the area, the corresponding load is 83 kN. Hence the incorrect conclusion is that the column could withstand a load of 83 kN with a safety factor of 2.
But if the 83 kN load were actually applied then the safety factor is n = failure load/actual load = 134/83 = 1.6 - significantly less than the 2 expected.

International Wastewater System (CSE:IWS) has announced it is collaborating with a licensed marijuana cultivator in the United States.
As quoted in the press release:
The collaboration enables IWS and the Cannabis Cultivation Facility to exchange data and evaluate the application of IWS’s thermal energy exchange technology in an industrial marijuana growing facility.
IWS has already demonstrated the environmental and economic benefits of its technology in a Canadian greenhouse installation at the Water Resource Centre in Sechelt, British Columbia (“Sechelt Greenhouse”). IWS installed a SHARC thermal energy exchange system at the Sechelt Greenhouse, which is connected to a primary building loop and used to reduce space heating, cooling & water heating costs at the greenhouse (see details: https://goo.gl/Mp0Z7u).
A study by scientist Evan Mills, with the Lawrence Berkeley National Laboratory, revealed that legalized indoor marijuana-growing operations account for 1% of total electricity use in the US, at a cost of $6bn per year. Annually, such consumption produces 15m tons of greenhouse gas emissions (CO2), equal to that of three million average cars.
IWS is working with the Cannabis Cultivation Facility to jointly evaluate the energy efficiency of IWS’s thermal exchange technology when integrated with the growing facility’s heating, ventilation and air conditioning (HVAC) infrastructure. IWS’s technology enables heating (heat transfer) and cooling (heat dissipation) applications, both a significant component of overall energy costs for the Cannabis Cultivation Facility.


The Turkish President inaugurates the "Çanakkale Bridge", the longest bridge of its kind in the world, coinciding with the 107th anniversary of the Ottoman Empire's victory in the Battle of Çanakkale.
The Opening Of The "Çanakkale Bridge", The Longest Of Its Kind In The World!
Turkey commemorates the 107th anniversary of the victory of the Ottoman Empire in the Battle of Çanakkale against the Allies, by opening the Çanakkale 1915 bridge, the longest of its kind in the world. Turkish President Recep Tayyip Erdogan participated in the opening ceremony, on March 18, 2022.
The name of the bridge "Çanakkale" refers to the city where the battle took place, while the 1915 figure stands for the year of the battle.
Bridge information and specifications
According to Turkish reports and the statements of Minister of Transport and Infrastructure Adil Kara Ismailoglu, the "Çanakkale 1915 Köprüsü Bridge" is characterized by the following:
It is 3,860 meters long, while the distance between the two towers (columns) is 2023 meters, with 6 lanes (3 to go and 3 to return).
It is the longest of its kind in the world and surpassed the "Akashi Kaiko" bridge in Japan, which held this title with a length of 1991 meters.
The 1915 Çanakkale Bridge reduces the travel time between the two banks to only 6 minutes by car, instead of the hour and a half that it used to take for ships to cross before.
The bridge is based on two bases with a length of 333 meters on each side, while the height of its towers is 318 meters, which is higher than the height of the Eiffel Tower, which is 300 meters.
The total annual savings will be 737 million TL ($85 million).
The first bridge outside Istanbul connecting Asia to Europe!
Çanakkale Bridge will be the first bridge that connects the continents of Asia and Europe outside Istanbul, and it will also be the first permanent bridge over the Dardanelles that connects the Sea of Marmara with the Aegean Sea.
The bridge connects the two banks of the Marmara Sea from the Çakkarkaya region of Labaski district (the Asian side of Çanakkale state), and the Sutluga site of Gallipoli district (the European side of Çanakkale).
It is noted that the Çanakkale Bridge gives the state importance in the transport line from the "Thrace" region of the north-west of the country, to the Aegean and the Mediterranean Sea, and will give it importance in the Marmara region as well.
The most important sections of the Istanbul-Izmir highway
The 1915 Çanakkale Bridge is the most important section of the highway project linking the states of Tekir Dag, Çanakkale, and Balikesir, which is 352 km long and includes 31 bridges, 30 bridge intersections, 143 upper and lower corridors, and 5 tunnels.
The highway also links the cities of Istanbul and Izmir and would contribute to easing traffic in Istanbul, especially on suspension bridges, and significantly reduce transportation costs to the Aegean region
It was done a year ahead of schedule!
According to experts, the Turkish government's interest in the completion of the Çanakkale Bridge is a prelude to moving on to other giant projects, which accelerated the implementation of the bridge, and its opening a year ahead of schedule.
The foundation stone of the bridge was laid on March 18, 2017, and it cost more than 10 billion TL ($1.2 billion).
The bridge was carried out by 5,000 workers, including 649 engineers, with 809 vehicles used for heavy equipment.


In this realization the objective was to lowering the ceiling avoiding to close it with panelling. Our internal designer has evaluated the possibility of using continuous sheets of 100 mm height in order to create a continuity in the curves and a play of light and shadow.
The choice of working with zinc/titanium was made to contain the weights and allow us to use non-invasive ceiling hooks. We have obtained a particular colouring thanks to an epoxy paint that has the characteristic of providing different shades depending on how the light invests the metal.
The installation of the product is very simple, which is fixed to the ceiling through retractable hooks.

The length of the soakaway drainage field drains is determined by the number of bedrooms in the house and the porosity of the soil. The new regulations state that for any house up to and including 3 bedrooms, the minimum size sewage system that can be installed is for 5 persons, with one extra person added for each extra bedroom. A 3 bedroom house requires a 5 person plant, a 4 bedroom house a 6 person plant, etc.
The porosity can only be determined by a percolation test which measures the time it takes for water to drop 1mm. in the percolation test hole. From this time, known as a V value, the length of drain required can be calculated.

Beam and Infill Suspended Floors
Using insulating block infill – getting the best of best worlds
Specifying insulating materials for block infill is a win-win option. Structural integrity isn’t compromised, but thermal performance is vastly improved. Additionally, many insulating materials are, by definition, light in weight. This means they can be speedily and easily installed by trained workers – and are safer to handle.
The structure’s basic design has remains unchanged – T-shaped precast concrete beams are laid in rows suspended on the inner leaf of the main walls. The gaps between the beams are then infilled with blocks.
In the earliest iterations of this system, the block material was usually concrete. Now, increasingly, architects and construction companies are specifying materials with more attractive insulating properties – and which are also easier to install.

Concrete Pre-formed Stadium Seats
A cost saving initiative to block and mortar. These stadium seats are preformed with only the base layer requiring a concrete base.
Time saving adds to the cost effectiveness as they can be installed very quickly and with ease.
Suspended Paving for flat top roofs
Unlike conventional paving or tiling on a concrete slab in which the pavers or tiles are fixed using and adhesive, our pavings are supported using rubber struts or concrete fixing without the use of an adhesive. The pavers are placed with 5mm spacings between each paver to allow a permeable surface for water run off.
This ensures that we do not interfere with the waterproofing on the roof.
- We now can create a level paved surface which can be sloped for run off purposes
- We effectively create a situation where no water pooling occurs
- An effective protection layer is created shielding the waterproofing from UV and other possible damage
- Usage can now be made on roof tops and balconies which were previously unused

Mr. C. Scott De Golyer has been very helpful in giving us the following information about the recording gauge installed at St. Helena to check the water stage of the river. This station was established by George M. Brett and Charles E. Allen on August 14, 1908. It consisted of a standard Geological Survey chain gauge attached to the lower chord of the first left-hand panel of the middle span of the highway bridge. It was converted to a recording gauge station by W. G. Hoyt and C. S. De Golyer on August 24, 1911. The first recording gauge was a Gurley printer indicating the river stage every fifteen minutes. The St. Helena gauge house, was believed to be one of the first in the United States that was built of concrete.
The St. Helena gauging station was discontinued on September 30, 1950, because it was in the area affected by waters impounded by the Mt. Morris dam. It was replaced by the station at Portageville, which had been established in December, 1945. The average daily flow of the Genesee River at St. Helena for the forty-two years of record was 1,223 cubic feet per second. The maximum flow during the same period was 44,400 cubic feet per second, on May 17, 1916; the minimum was 18 cubic feet per second on October 5 and 17, 1913. The drainage above St. Helena was 1,017 square miles.
The ground water observation at Castile was established by John Ferris on November 18, 1942. It is officially designated as WO-1 (meaning first observation well in Wyoming County). It is located on the former Lyman Brainerd farm near St. Helena. It was a “hand measured” well until October 17, 1951, when the standard tape gauge was installed. For the ten years of record, the average water level has been about 5.6 feet below the measuring point or land surface elevation. The highest level of water in the well was in February 1945, when it was only 0.58 feet below the land surface. Its lowest observed level was 12.92 feet below the measuring point on November 23, 1952.
The purpose of the ground water observation is to aid in a study of the water level throughout the United States. Readings are taken weekly by Mr. De Golyer who reports them to the U. S. Department of the Interior.
Herman Piper read the chain gauge on the St. Helena Bridge from the time of installation in 1908 until 1919, when Glen Streeter took the readings for a time; after this, Mr. De Golyer took over until the stations were discontinued in 1950. Both kinds of readings were taken to check on accuracy.

The building blocks created by Professor of the Institute of Civil Engineering of Peter the Great Saint-Petersburg Polytechnic University Andrey Ponomarev and a graduate student Alexander Rassokhin, increase load-carrying capabilities by more than 200 per cent and are resistant to corrosion, frost and “aggressive environments”.
Researchers calculate that buildings constructed with the blocks could last longer and be more resistant to earthquake activity than traditional structures.
"Such system allows to ensure the structure integrity even in conditions of seismic activity, since the load is distributed throughout the structure as a whole, and not by individual reinforcement bars. The invention can be used in the construction of bridges and pedestrian crossings, non-metallic ships, low-rise residential buildings" says Alexander Rassokhin.
