Surface wave method Methods Definition of transverse wave propagation velocity by MASW method In engineering seismic exploration, using the simplest surface sources of elastic waves, more than 85 percent of the impact energy is spent on the formation of low-frequency and low-velocity surface waves. The following seismogram, obtained on the asphalt pavement of the embankment with an 8 kg sledge hammer pulse, illustrates the dominance of low-velocity surface waves in relation to refracted and reflected waves. Being the strongest hindrances for the method of reflected waves, Rayleigh surface waves at the same time contain very valuable information for the study of soil properties about the velocity of propagation of transverse waves. The seismogram with the records of surface waves The most advanced and rapidly developing at present in shallow seismics methods of processing based on multi-channel analysis of surface waves (MASW), gives quite a detailed one and two – dimensional model of shear wave velocities Vs distribution in the soil mass. A natural limitation of the MASW technique is a small depth of penetration of the surface wave energy into the soil massif thickness. An essential factor for increasing the depth of the method is the possibility of attracting passive low-frequency noise of transport and operating mechanisms for joint analysis with the records obtained in the active mode. The main precondition for multichannel frequency analysis is the predominance of the energy components of transverse displacements during propagation of oscillations along the surface of the media and frequency dispersion of phase velocities – an increase of visible period and, accordingly, an increase of the penetration depth of surface wave energy into the thickness of the soil massif. The matrix of phase velocities of several Rayleigh surface wave modes characterizing strong frequency dispersion of phase velocities is shown below. The dispersion curves of the zero, first and second harmonics of the surface wave are used for calculation of the transverse wave velocities model. Selection of dispersion curves of Rayleigh surface waves phase velocities and construction of a single-dimensional model of transverse wave propagation velocities The above results of multichannel analysis of surface waves are obtained using RadExPro software complex (Deco-Geophysics, Moscow). Assessment of soil physical properties on the basis of complex interpretation of longitudinal and transverse wave velocities The sections shown in the figure characterize the typical ratio of representativeness of geotechnical methods, drilling and geophysics in assessing the physical properties of the soil massiif. Despite the relatively high density of drilling points and dynamic penetration testing, they do not provide detailed spatial configuration presentation of the boundaries of engineering-geological elements within a relatively homogeneous array of moraine loams. At the same time, the transverse wave velocities, which characterize, first of all, the properties of the soil skeleton, give a clear spatial picture of the distribution in the moraine loams of large-block fraction clusters (moraine ridges) with increased velocity of the transverse wave propagation. In geotechnical surveys, several types of waves are usually used to assess the state and properties of the soil massif and its saturated fluids: longitudinal reflected, refracted and surface waves. The following figure shows the types of seismic sections in one of the profiles in the central part of Latvia. In the upper part of the section up to 35 m of moraine loams lies, then about 20 m of Plavinian dolomites, below- the upper devonian sediments – Amata-Gauja sandstones lie. At a depth of 160 m (both sections in the depth scale) on the CDP section a fairly well-correlated boundary follows, perhaps the bed of the Amata-Gauja sandstones. These materials obtained with the use of 8 kg sledge hammers and a single 64-channel receiving arrangement of geophones with a step of 2 m. However, the complexity of the field work and data processing for these sections varies considerably. So, if during obtaining of CDP cross-section by the reflected waves, the interval between shot points was 2 m, to obtain velocity sections from refracted and surface waves were used only seismograms that were obtained with a step of shot points along the profile 16 m. Calculation of the sections of soil physical properties on high mountain deposits of placer gold in Chucapaca (department Moqeguia, Peru) Examples of determining of transverse waves propagation velocity according to MASW and prediction of physical and mechanical properties of soils using the method of refracted waves along one of the lines of the working of the gold-bearing field in the South of Peru are shown in the following figure. Based on the longitudinal waves propagation velocity sections obtained from first arrivals of refracted waves and transverse wave velocities from MASW method the sections of the forecast density, Poisson’s ratio and elastic modulus are calculated along one of profile at the site of placer gold deposits working (Chucapaca, department Moquegua, Peru).

Nowadays, in almost every type of building it is necessary to create a proper ventilation and air conditioning system. It is thanks to them, regardless of the weather conditions outside, that we can maintain the most optimal temperature and humidity in the rooms we are staying in. Currently, freon air conditioning is the most commonly used air conditioning in the world, but as it turns out, the installation of ice water may be a better alternative - explains energycool.pl employee.
Chilled water unit - working principle
In this particular type of refrigeration plant, it is the ice water that is the working medium. As far as its construction is concerned, it is the same as in heating systems. The difference, of course, is that it is fed with cold water. Ice water is produced in a chiller, or ice water generator. It then moves through the pipes from the source to the receivers.
The most common form of ice water is usually a solution of ethyl or propylene glycol with water or other brine. This is due to the rather uncomfortable clotting of ice water.
Chiller is a source of chilled water, it acts as a heat exchanger. This type of equipment is most often used in hotels, production halls, shopping malls or office buildings and provides a source of cooling for air conditioning.
A chiller installation is better than a freon air conditioning system because it has greater resistance to failures. This is due to its increased tightness.
The chiller works in conjunction with a cooler or fan coil. The first of these devices is placed in the air handling unit, while the second one in the room itself.
Chiller - scheme
An installation that uses chilled water consists not only of its unit, but also of fan coils, which are water-air heat exchangers. When air flows through the fan coil, the temperature of the ice water in it will rise by about 5-6 degrees Celsius. A pump that feeds water at pressure is also extremely important in such an installation, thanks to which ice water can be transported to the final consumer.
The most important part of the installation is, of course, the chiller, which makes it possible to drain heat from the water. The chilled water produced in this way is delivered to fan heat exchangers or similar terminal equipment and then returned to the unit when heated. It should also be noted that the heat exchangers are cooled by evaporators through liquid coolers and condensers.
Why is evaporative cooling good? Air itself, although always available, has worse thermodynamic properties than water. Therefore, the combination of these two factors in a cooling system allows for the best possible use of their advantages, while limiting the disadvantages. Ice water can be used for both absorption and evaporation cooling.
If there is direct contact between the water and the air, and if there is also a heat input, there is a process of non-diabatic evaporation of water into the air. Thus, there is a latent heat dissipation of the air humidifying water vapour and a sensible heat dissipation, which is absorbed by the air stream from the surface of the water itself.
An installation using chillers is a better and cheaper solution than freon air conditioning, but we must also take into account that it is more difficult to design it.


Beginning in April of 2019, 22nd Avenue between Minnesota Drive and Eastbrook Drive will be getting a major upgrade. The project includes full reconstruction to widen the current roadway, replacement of underground utilities, traffic signal upgrades, new street lighting, sidewalk, and a shared-use path. This construction will not impact visitors ability to drive into town, from Interstate 29. Sixth Street (Highway 14), which goes across 22nd Avenue remains open. The only detour to be mindful of begins on Sunrise Ridge Road and Eastbrook Drive (as shown on the Detour Map). Traffic control and signage will be installed along the project to inform the public.

What is spray foam?
Spray foam or SPF is a spray-applied material that is widely used to insulate in air seal buildings making the buildings more energy-efficient and comfortable. According to the Department of Energy, 40% of a building’s heating and cooling energy may be lost to air infiltration making energy use unnecessarily high. For solving this problem we can easily use SPF. SPF is air impermeable so it is a highly effective solution in reducing unwanted air infiltration.
How does SPF work?
SPF is unique because it’s applied on-site as a liquid allowing it to form and extend to cover surfaces creating a seamless barrier that fills gaps holes and air leaks.
SPF is most commonly used as:
1. A wall cavity insulation
2. An air barrier helping to seal a structure
3. Low-slope roofing systems on commercial buildings or residential homes with low sloped roofs
4. A sealant for windows doors and other small cracks gaps and holes.
SPF is a great product that maximizes thermal efficiency because it can serve as an insulation and an air barrier giving a building warm in the winter and cool in the summer.

General, Remedial and Provisional Use Approvals for the Waterloo Biofilter™ there must be a maintenance agreement in force for the life of the system. The system must be inspected and maintained by a Massachusetts certified wastewater treatment plant operator Grade 2 or higher. The following is a summary of the inspection and effluent testing requirements for General, Remedial and Provisional Use.
The Waterloo Biofilter must be inspected at a minimum of once per year and field tests for pH, Dissolved Oxygen (DO) and Turbidity must be performed on the system effluent. If system effluent does not pass the field tests a sample be must be analyzed in a certified laboratory for Biochemical Oxygen Demand (BOD) and Total Suspended Solids (TSS). Effluent quality must be below 30 mg/L BOD and 30 mg/L TSS.
Waterloo Biofilter systems servicing single family homes with design flows less than 2,000 gpd must be inspected and field tested (pH, DO and Turbidity) twice per year. If field tests fail, a sample must be analyzed by a laboratory for BOD and TSS and be below 30 mg/L for both parameters.
Commercial systems and residential systems with design flows greater than 2,000 god are required to have quarterly inspections and sampling. All effluent samples are to be analyzed in a laboratory for pH, BOD and TSS and meet the 30 mg/L limit.
Systems used for Nitrogen reduction require additional quarterly sampling for Total Nitrogen (TN) and Alkalinity. TN results must be <19 mg/L. Nitrogen reducing systems treating flows larger than 2,000 gpd must be sampled monthly and treat to <25 mg/L. The state can be petitioned to reduce sampling after 2 years for smaller systems and after 3 years for systems treating flows larger than 2,000 gpd.
Quarterly inspection and maintenance reports along with sampling results must be filed with the Massachusetts DEP and the local board of health.

How to install an opening roof
Installing an opening roof over a pergola or patio involves eight main processes. The installation of opening roofs has been refined by builders and designers, making it simpler than ever to construct outdoor living spaces that provide all-year protection from the weather.
The majority of opening roofs are built in 3 to 5 days, depending on the system’s complexity. Some businesses provide installation instructions with their roof sales that include everything from measuring and marking to attaching support beams and brackets. DIY aficionados could find this adequate, but the majority of house and business owners would require expert installation.
The installation procedure has been improved in this situation for both home and business settings.
- Each component of the opening roof is included, along with thorough step-by-step installation instructions, in a comprehensive 3D assembly/installation package created by the architectural and design team.
- The authorized dealer suggests a reputable installation crew near you.
- The dealers, design team, and installers maintain continuous contact from design idea to manufacture and on-site installation to assist speed up the planning process.
- The team members get an engineering package that is specially designed for the project before the date of installation.
- Planning effectively aids design and installation teams in identifying the best solutions and anticipating possible problems.
- The installation crew makes sure the system is professionally installed in accordance with regional building and safety requirements.
Regardless of how simple it may appear, installing an opening patio roof calls for more than just a drill and a level. A correct fit for each component requires time, expertise, and experience. It makes sense to hire a professional to handle the installation in this case, whether it’s for a deck, pool area, courtyard, patio, or outdoor kitchen.

THE UK government has played down reports that Chinese companies could get involved in the construction of the high speed rail network HS2.
Trade magazine Building reported that China Railway Construction Corporation (CRCC) recently wrote to HS2 Ltd's chief executive, saying it could build the line in around five years, for a much-reduced price tag.
The CRCC letter, which has also been seen by the Financial Times, said that “we are certain that we can offer a cost that is significantly lower than the projections we have seen”.
Last week Prime Minister Boris Johnson finally gave the green light for HS2, in spite of concerns that costs might spiral from the budgeted 62 billion pounds sterling to over 100 billion pounds sterling.
Appearing on BBC TV, Transport Secretary Grant Shapps said that there were currently no talks between the UK government and Chinese companies over the project.
"This has not been a discussion with the Department [of Transport], it's been a discussion with HS2 as I understand it,” says Shapps, adding that “obviously I will be asking to see what the communication has been”.
HS2 is the UK’s single biggest and most expensive infrastructure project. The city centres of London, Birmingham, Manchester, and Leeds will be connected by 345 miles of new high-speed railway track. HS2 is expected to carry over 300,000 passengers a day when fully operational.
Under current plans, the final stretch of the line is not due to be completed until 2040 - though Johnson has said that he would like that date to be brought forward to 2035.


Carbonshack began in 2017 with a lofty vision: to create and promote zero-emission homes that inspire their users to become better stewards of the environment. Since then, the Los Angeles-based team of architects, designers, and tradespeople headed by Stephen Pallrand has continued to raise awareness about eco-friendly strategies in residential design. Whether it’s using non-VOC paints and finishes, reducing a home’s embodied carbon footprint by choosing repurposed and salvaged materials, or switching from natural gas to electric for home heating and cooling, the message is to do something.
The firm’s case study for building green is Casa Zero, Pallrand’s own home in Mount Washington. Designed to take into account the entire life cycle of the structure and everything in it, the new, all-electric dwelling is constructed of reclaimed, recycled, and low-impact construction materials and is equipped with features such as solar panels and a heat pump water heater. “The goal was to see how low could we get the footprint of a newly constructed home,” explains Greg Roth, CarbonShack’s senior interior designer.
Historically, the building sector has been a major contributor of greenhouse gas emissions around the world. According to the nonprofit research organization Architecture 2030, the built environment produces close to 50 percent of annual CO2 emissions globally. Of these, building operations are responsible for 27 percent, while building materials and the construction process are responsible for an additional 20 percent. “Sustainability is important and crucial for our industry,” Roth notes. “We’re showing that it can be done beautifully.”
Pallrand, who launched CarbonShack as an offshoot of his sustainable designbuild firm Home Front Build, contends that a home is only as eco-friendly as its inhabitants. To make the process of building green easier to understand, CarbonShack created the interactive “Embodied Energy Calculator,” which allows professionals and non-professionals alike to tally a home’s embodied energy (aka the greenhouse gas emissions generated by the harvesting, manufacturing and transportation of materials, the construction process itself, and the disposal of these materials) and compare the CO2 savings gained by swapping out a particular material for another. Their companion website, sustainablebuild.org, meanwhile, is a tool for calculating how much energy a home generates yearly and how that number can be lowered by transitioning to energy-efficient technologies and appliances.
In October, CarbonShack opened a showroom featuring sustainable interior products, including lighting, textiles, and furnishings. Notes Roth, “Finishes are as important as the systems that go into the home, and we wanted to highlight that.
But he emphasizes that helping to save the planet doesn’t have to be an all-ornothing proposition. “It can be overwhelming as a homeowner if you have a historic home or even a new home prospect,” he says. “We’re not advocating orthodoxy. We’re saying: do something. One small step can make a difference.”


Sarasota County Public Works Staff plans to initiate DeSoto Acres Community workshops to continue planning for sidewalks on select streets in DeSoto Acres. Per the County, the project is slated to start construction in 2023. Design and Engineering has not started.
Roads identified for sidewalks, on one side of the road are, Tuttle Avenue and DeSoto Rd. The County has identified other roads in DeSoto Ares for sidewalks. A survey was sent to residents along these roads to determine if they want sidewalks or not.
BACKGROUND: Sarasota County has proposed sidewalks in the DeSoto Acres Subdivision (West of Lockwood Ridge Road) on the following streets, located on the side indicated below:
- Tuttle Avenue (from 61st St to Myrtle St) – East side of the street
- DeSoto Road (from 301 to Lockwood Ridge Rd) – South side of the street
- 47th Street (from Shade Ave to Lockwood Ridge Rd) – South side of the street
- Shade Avenue (from DeSoto Road South to 47th St) – West side of the street
The County held a public meeting on Jan. 27, 2015 to gather input from DeSoto Acres Subdivision residents and residents along Tuttle Avenue from 47th St. to Myrtle St. The following visuals were provided for public review and input.
There was a good turnout at the public workshop. Your input, plus letters and emails to the County Sidewalk Committee are an important part of the sidewalk evaluation process. To view the DeSoto Acres Association Board’s comment letter to the County Sidewalk Design Team click on the link.

At Vätternrundan we constantly strive to enhance the experience of our events, one element is the work to get even safer races. Extensive external and internal evaluations are continuously made and one area that has been clearly identified and in need of development is the part at northern Vättern. This in combination with the near future extensive redevelopment of highway 50, makes the work on finding an alternative route extra important. This new route can become a reality as early as 2020, which in addition to raising the safety level would also mean a certain extension of the route. At present, several different alternatives are being processed together with the Swedish Transport Administration (Trafikverket). We will keep our participants and other stakeholders informed on an ongoing basis.


The general problem of optimum design of trusses composed of tubular elements requires the determination of cross‐sectional dimensions for each element which satisfy a set of side constraints on those dimensions as well as Euler and local buckling constraints. A formulation is presented which eliminates the necessity to use mathematical programming methods for the determination of feasible cross‐sectional dimensions. The minimization problem is shown to be expressible in terms of area variables only, with each area subject to bounds which are functions of truss stiffness but which may be obtained by explicit analysis of the element ‘desing space’ for any design. This‘direct’ formulation is completely general and compatible with any minimization algorithm. The formulation also leads to a simple and efficient recursive procedure for producing near‐optimal fully‐constrained designs. Several examples illustrate results obtained by both the direct and recursive procedures.

Yay! A new walking (and possibly biking trail) for North Seattle is in the works! This will be a welcome relief for the crowded Green Lake path.
With about 200 acres, Jackson Park Golf Course is the largest green space in Seattle. Located on the North Seattle boundary (NE 145th Street) and seen from the freeway, the trail will be a significant improvement for the neighborhoods in the area.
The North Seattle local community, (Friends of Jackson Park Trail), along with Seattle Parks Department and Seattle City Department of Neighborhoods are working together on plans to develop a 4 mile trail around the perimeter of the golf course.
The Friends of Jackson Park Trail is made up of volunteer residents. They have been awarded $15,000 grant from the Seattle Department of Neighborhoods. So far, they have formed a steering committee, developed the visioning plan and then used the grant money to hire a landscape architect consultant.
Larson Casteel was selected to develop the North Seattle trail plan and prepare a preliminary cost estimate. They will also record feedback from the public meetings. The first of three public meetings will be held Tuesday, June 22 at Jackson Park Golf Course.
This first meeting will include an update on the work performed so far, gathering input to develop the trail design and a presentation of the site analysis.
Concern about wetlands, preservation of habitat areas and green space, green infrastructure techniques, public safety, connection to other existing green spaces and future plans for the area such as the light rail station are all consideration in the creation of the trail.
Completion of the Jackson Park Golf Course Trail is expected in a couple of years. Jackson Park is one of four public golf courses and one of two which are included in a city wide initiative called "Bands of Green" to develop bicycle and pedestrian trails and linear parks in Seattle.

Understanding What is Building Regulation in London's Architectural Landscape
In the dynamic world of architecture, there are fundamental rules that govern the design and construction of buildings. In the heart of this framework lies the answer to the question, “What is building regulation?”
These guidelines, steeped in the balance of innovation and safety, dictate the transformation of architectural dreams into inhabitable realities.
What is Building Regulation in a Nutshell?
Building regulation refers to the standards set by government bodies to ensure individuals’ health, safety, welfare, and convenience in and around buildings. In the UK, these standards encompass diverse aspects ranging from structural integrity, fire protection, and energy efficiency to hygiene, sound insulation, and accessibility. Compliance with these standards isn’t merely a suggestion; it’s a legal requirement. Top architecture firms in London can help ensure your project meets these essential regulations.
These regulations play a crucial role in shaping the London architectural landscape, with every edifice telling a tale of thoughtful design woven together with regulatory compliance. It’s a testament to how London Architect has skilfully harmonised creativity and regulation.
Key Elements of Building Rules
Health and Safety: Building regulations are pivotal in ensuring the safety and health of people using the building. They cover structural integrity, fire safety measures, and minimum standards for sanitation.
Energy Efficiency: These regulations lay down standards for insulation, heating, and lighting, thus promoting energy efficiency and environmental sustainability.
Accessibility: The regulations demand that buildings are accessible to all, including those with disabilities. They cover the provision of lifts, ramps, and suitable entrances.
Sustainability: Building regulations also focus on sustainability, pushing for the use of eco-friendly materials and technologies.
Building laws aren’t confined to exteriors; they extend their influence into the heart of buildings – their interiors. For instance, how does building regulation intertwine with interior design London? It can shape everything from room sizes to hallway widths, from the number of electrical outlets to the type of lighting fixtures.
The Impact of Building Regulationson London's Architecture
Building rulings have considerably shaped London’s unique architectural character. A walk through the city is like stepping into an architectural textbook, with buildings that reflect varying eras, styles, and technological advancements, all abiding by building laws. These regulations ensure that despite the stylistic diversity, all structures are safe, accessible, and energy-efficient.
For instance, a structure as iconic as The Shard wouldn’t be as impressive if it weren’t compliant with the regulations concerning its height, the materials used, and the safety measures implemented. These factors underline how adherence to building regulations not only preserves safety but also contributes to the city’s distinctive architectural legacy.
Navigating Building Laws with Professional Help
Given the complexity of building regulations, interpreting and applying them to a construction project can be challenging. That’s where the expertise of a professional Architect in London comes into play. Their profound understanding of building rules, coupled with their innovative design ideas, can seamlessly integrate compliance with creativity.
Building design architects can help prepare the necessary documentation, secure approval, and ensure the construction adheres to the approved designs. This way, you can focus on your architectural vision while being assured of regulatory compliance.
In architecture, building regulations serve as the binding thread between safety, functionality, and aesthetics. They guide the transformation of architectural concepts into physical structures that stand proudly on London’s skyline. An architecture design company can play a crucial role in navigating and adhering to these regulations.
Understanding these regulations is critical, whether you’re an aspiring architect, a homeowner planning a renovation, or a lover of architecture appreciating the city’s skyline.
Unravelling Building Regulations in London
In summary, building regulations are the backbone of safe and functional architecture in London.

- 07 Jul 2020
Earthquake Events and Parameters
Tuesday, July 7, 2020 at 11.44.14 WIB the Lebak region was rocked by a tectonic earthquake. BMKG analysis results show this earthquake has an update parameter with a magnitude of M = 5.1. The epicenter of the earthquake was located at coordinates 6.70 latitude and 106.15 east longitude, or rather located on land at a distance of 18 km southwest of Rangkasbitung, Banten at a depth of 87 km.
Types and Mechanisms of Earthquakes
By paying attention to the location of the epicenter and the depth of the hypocenter, the earthquake that occurred was a type of medium earthquake due to subduction of the Indo-Australian plate which sank beneath the Eurasian plate. The results of the analysis of the source mechanism show that the earthquake has an upward movement mechanism (Thrust Fault).
This earthquake shaking is felt in the area of ??Lebak III-IV MMI (If during the day it is felt by many people in the house), Cihara, Rangkasbitung, Bayah, Pandeglang, Malingping, Cibeber, Banjarsari, Sukabumi III MMI, Jakarta, Depok, Bandung II-III MMI (Vibration felt real in the house. Feels of vibration as if a truck will pass), South Tangerang, Bakauheni II MMI (Vibration felt by some people, light objects are hanging rocking). Until now there has been no report of the impact of the damage caused by the earthquake. The modeling results show that this earthquake is NOT TSUNAMI POTENTIAL.
Until Tuesday, July 7, 2020 at 12.07 WIB, the BMKG monitoring results have not shown any aftershock activity.
The public is urged to remain calm and not be influenced by issues that cannot be accounted for. In order to avoid buildings that are cracked or damaged due to the earthquake. Check and make sure the building where you live is quite earthquake resistant, or there is no damage due to earthquake vibrations that endanger the stability of the building before you return to the house.
Make sure official information is only sourced from BMKG which is distributed through official communication channels that have been verified (Instagram / Twitter @infoBMKG), website (www.bmkg.go.id), or through Mobile Apps (iOS and Android "BMKG Info").

What are Steel Screw Piles and how it’s useful?
The helical piles are Steel Screw Piles that are used for deep foundations. These are piles that are wounded into the ground. Some of the applications of the helical piles are mentioned below:-
Understanding The Difference Between Helical Piers And Push Piers
For those who think that the difference between helical piers and push piers is nil, need to rethink again as you might be missing some basic differences between the two. If you ever meet a read more...


Site – The site is long, stretching from a suburban Mellons Bay street to a sandstone cliff that overlooks the gulf islands. It curls its tongue, flat to the street, convoluting to a natural spring and watercourse two thirds along the site.
Pre-condition – An existing 1960's rectangular two storey house sat across the site like a dam, blocking any visual or visceral transition between the street and the sea. The house was in poor repair, largely due to a lack of provision in terms of the watercourse beneath. It was damp and poorly planned, and with a startling abandon, it ignored the landscape in which it was anchored.
Design – The new house was designed for an engaging couple with two grown children. Despite the allure of the seaward end of the site, the decision was made to pull back from the edge and avoid the heroic gesture, to let the landscape re-engage with the sea.
Conceptually, the house consists of two elements, oblique and sliding past each other, held in stasis by a bridging element that traverses a section of ‘reconstructed landscape’. The placement and geometry of these elements was derived from a parametric investigation of the site, in terms of the water flow from the road to the sea. This was further articulated by a series of water features that terrace downward through the courtyard into the middle of the house and connect to the natural watercourse below.
Environmental considerations –
Adaptive re-use. Much of the original house was recycled and reused on site. The floor boards and weather boards were used in construction, the steel beams and stone cladding from the original basement were used in the landscaping. An oak tree that stood on the site was chopped down, milled and the timber was used for the kitchen cabinetry.
Rainwater harvesting. The rainwater is harvested and stored in a 3500 litre tank beneath the house - utilising the basement area of the original house.
Solar. Solar energy is used for the hot water heating in the house.
Highly Insulated. The joinery utilises state of the art German profiles made from Acoya Timber (non-chemical treated Pinus Radiata timber).

WATER TREATMENT CASE STUDY
Brooklyn Park Water Treatment Plant
Brooklyn Park, MN
In 1998 the city of Brooklyn Park Minnesota expanded its water treatment plant to a capacity of 20 MGD. After 12 years of operation the mineral levels and water quality in their wells had changed and they were only able to consistently produce 16-17 MGD. In 2008, the city hired SEH Inc. and began an optimization and capacity upgrade project to bring the plant up to a peak flow of 26 MGD to meet the cities current and future needs.
The cities solution to the capacity issue was the addition of two new clarifiers to handle 5.5MGD each and a 9 MGD filter expansion. The water optimization upgrade included the addition of HEI plate settlers to reclaim the water from filter backwashes and clarifier wasting. The HEI plate settler process allowed the city to reclaim up to 98% of these streams with the additional benefit of a residuals management step. This step utilized the plate settler’s internal mechanical thickener to further the consolidation of their Iron and Manganese solids as well as capture any filter media lost during the filter backwash cycle. As a result, the city’s sewer maintenance and discharge costs were reduced.
The HEI plate settler system was installed in a new building addition. There were three HEI plate settlers, each capable of 1000 gpm. The plate settler process was designed with the flexibility of operating a single or multiple units as demand required. The HEI plate settlers have unitized tank construction, which cuts down on the footprint and building size by 25% over other competitive units. Each HEI plate settler has an isolated mixing and flocculation chamber with VFD motor control to optimize any chemical addition. The process uses PD pumps for sludge removal and solids recirculation. Each unit is equipped with effluent turbidity measurement and all facets of operation are scada monitored and controlled.

Sewage & Sanitation
The Borough of Heidelberg presently has a treatment agreement with Allegheny County Sanitary Authority (ALCOSAN), which treats all of the sanitary sewage generated from within Heidelberg. This agreement eliminates the need for a treatment plant in the Borough. The Borough operates and maintains over 15 miles of sanitary and storm sewer lines within Heidelberg. The system is primarily financed from sanitary sewer customer’s fees. Few tax dollars are used for the operation of the Borough’s sanitary sewers.
The operation of the Heidelberg Borough Sewer System is governed by the adopted Operation and Maintenance Program Plan. The plan is available for public review in the Office of the Borough Manager.
Heidelberg Borough’s sewer system is required by law through an Allegheny County Health Department Consent Order to conduct various preventive maintenance measures and repairs. The consent order requires Heidelberg to clean, televise and map our sewer system and repair significant defects; conduct a hydraulic capacity design evaluation; develop an operation and maintenance plan; develop a sanitary sewer overflow response plan; conduct flow monitoring; and develop a feasibility study to evaluate ways to eliminate sanitary sewer overflows. 61 municipalities and 14 authorities within Allegheny County are within this consent order; the goal of this order is to solve the problem of raw sewage backups and to limit overflowing into rivers, creeks and streams.


Indeed, the 100 smart cities is a pragmatic vision for India Inc. Cities are plunging to make space for themselves in the Smart City folio.
But the Question arises; what will make a Smart City ‘Smart’?
The known answer is ‘Technology’ but how a technology to gallop tilting Milestones. Well, a smart city comprises integration, expertise, understanding, coordination and synergy of different participants in the ecosystem. These include several aspects such as smart governance, smart energy, smart infrastructure, smart buildings, and smart service delivery mechanisms.
When we look into a country like India, a smart city is not about a single, or a certain industry segment. In broader perspective, it opens up opportunities for multiple growths across all industries. Smart city solutions are being developed to address a range of issues, including energy management, water management, urban mobility, street lighting, and public safety. These innovations are reinforced by general developments in areas, such as wireless communications, sensor networks, data analytics, and cloud computing.
Undoubtedly, Technology is the backbone of a smart city ecosystem transiting from urban planning to creating healthy environment, ensuring safety of people, smart and efficient power distribution, continuous water supply, intelligent traffic and transportation management systems that use analytics to provide efficient solutions to ease commuting, and surveillance systems requiring minimal human intervention.
Smart cities use advanced technologies such as virtualization, NFC, RFID, Internet of Things, etc. to be more intelligent and efficient in the use of resources, resulting in cost and energy savings by connecting devices/systems to internet. The concept of the “technology-driven” smart city has captured the imagination of public, private, and non-profit organizations in India.
Deluging of $15.3 billion for smart cities by the Government of India will not just push the border of urbanisation but also create a new set of markets for technology companies across a range of industries.
There is an estimation that a minimum of $315 million will outlay into the technology sector with this initiative, providing a great potential for technology businesses in this growing market. This in turn would open up the entry opportunity for companies across the globe with a market in India and provide them with a platform to export their services. With respect to verticals, the government needs to take a lead in removing barriers to innovation and facilitating collaboration between multiple diverse sectors. This has already begun to happen in the Assisted Living and Transport verticals, but more needs to be done.
In addition, continuous advancements in current technologies will aid in the transformation of existing cities into smart cities. Specifically, advancements in machine-to-machine (M2M) communications, the Internet of Things, and wireless sensor networks will play a large role in the success smart city projects.
Public and private organizations can use M2M technology to obtain key information about their devices, allowing them to gain better insight into the needs and wants of their community, hence driving better quality of life for city residents.


Newly surfaced and re-striped parking lot in Detroit Lakes, MN. There is no van-accessible parking space (one is required ), there is no van accessible access isle (needs to be 96″ wide), the accessible parking spaces for cars is not wide enough (needs to be 96″ wide), and the access isles for the car parking spaces is not wide enough (needs to be at least 60″ wide). UPDATE: There is a correction for this post. The Minnesota standards for accessible parking spaces state: each accessible parking space must be 8 feet wide (96″) and all accessible parking spaces must have an adjacent 8 foot wide access aisle (96″). Each access aisle shall be marked “no parking”. One in six parking spaces shall be van accessible.


What goes wrong

Building another absorption field is sometimes the only cure for septic fields that have lost their efficiency. Resting a field for a year can restore it to near original capacity. Having two fields can extend the life of a septic system, and is often the best approach in areas where the ground contains a significant amount of clay.
Septic tanks, by their nature, accumulate solid material over time. About 50 percent of this material will decompose, thanks to the bacteria that are naturally present in all septic systems. The rest has to be pumped out on a regular basis. If too much of it accumulates, it can cause several problems.
First, the solids take up too much space in the tank, which greatly reduces the tank's treatment volume. In other words, it can't hold household wastewater long enough to adequately treat it. As a result, the tank has to release partially treated wastewater into the septic field. Over time, these wastes can clog the field and reduce its disposal capacity. In other words, the field simply won't work as well.
Solids can also reach the outlet level and flow into the leaching bed, where they plug the pipes or the bed. The result: a clogged septic field. If the tank's baffles are working properly, they'll prevent this, but baffles can disintegrate or collapse, especially in older tanks that have seen many years of service.
Both scenarios can be hazardous to the environment and your health, as they can contaminate drinking water supplies. They can also have a significant effect on your property values. Finally, they can create a big hole in your wallet, as repairing a septic system can mean digging out the old system and relocating the drain field. Depending on where you live, you might be required to replace the entire system and any damaged landscape.
