Ways to Reduce Soil Compaction
After unseasonably wet, cold weather this spring, farmers are eager to get their seed in the ground but they must be conscientious of soil compaction. We understand their sense of urgency, but we also know they’ll have better results if they wait for more suitable field conditions.
The best rule of thumb is to let the field dry before doing fieldwork. Use a quick field test to check the soil moisture: mold a length of soil between your index finger and thumb, or roll it into a ball in your hand. Observe whether the soil breaks apart as you work it. If you toss the ball of soil into the air and it shatters or cracks upon falling to the ground, then conditions are likely suitable for tillage or planting.
Working soils that are too wet this spring could have negative impacts on your crops during the growing season including: stunted plant growth; slow infiltration of water and/or ponding; high surface runoff and soil erosion under normal or light rainfall; poor root system establishment; and nutrient deficiency.
To reduce or minimize soil compaction:
- Avoid working wet soil. Soil is most susceptible to compaction when it’s saturated and cannot absorb any more water. Use the quick field test method above to access the soil conditions, and begin planting or working the soil only if the proper conditions exist.
- Reduce tillage. Crop residue can intercept raindrops and prevent the soil surface from sealing and compacting.
- Use the right implements. The degree of compaction is determined by the moisture content of the soil, as well as the weight of the equipment in the field. Reduce the weight on each axle, choose wider tires and adjust air pressure to reduce the load on the soil surface. Iowa State University research shows that using equipment with 6 pounds per square inch (psi) of surface pressure yielded 9 bushels per acre more than equipment with 16 psi.
Soil compaction can be avoided with better management. For more information, click here to download Iowa State University Extension’s publication, Understanding & Managing Soil Compaction.

House: Ramkrishna House, 1962-64 Architect: Charles Correa Style: Modern Indian Architecture Location: Shahibag, Ahmedabad, Gujarat, India
The Architect Behind Ramkrishna House
The late Charles Correa was one of India's pioneering architects, urban planner and activist. Credited with setting the tone for Independent India, he crafted the language for modern Indian architecture, using climate sensitive building technologies by combining traditional methods and materials in building construction. In addition to receiving a Royal Gold Medal for Architecture by the Royal Institute of British Architects in 1984, he is the recipient of the Padma Shri in 1972, and the second highest civilian honour, the Padma Vibhushan, given by Government of India, in 2006. In 1984, he founded the Urban Design Research Institute in Mumbai, dedicated to the protection of the built environment and improvement of urban communities.
What Makes Ramkrishna House So Iconic?
Better known for his institutional structure, Charles Correa's first important project was "Mahatma Gandhi Sangrahalaya" (Mahatma Gandhi Memorial) at Sabarmati Ashram in Ahmedabad (1958–1963); the Ramkrishna House was completed in the following year. Before understanding this particular home it is important to look at Correa's most iconic project, the Tube House.
In 1960, the Gujarat Housing Board held a competition to encourage new ideas for low-cost housing. The Tube house unit was 18.2 metres long by 3.6 metres (60 ft x 12 ft). The sloping roof, along with adjustable louvers by the entrance, used the convectional flow of air currents to naturally ventilate the home. As it had an open floor plan, the section of the house had different levels (without doors) to create pockets of privacy. Built at the height of the Indian socialist movement, the opposing spectrums of the Ramkrishna House and Tube House further cement Charles Correa's position on housing design in India.


Street Improvements Underway
Construction has started on improvements along 8th Ave at Mistletoe Blvd, with improvements at the Cooper intersection to follow later this year. These projects are the direct result of a study completed in 2018, identifying several locations for pedestrian and vehicular circulation and safety improvements. At the intersection of Mistletoe Blvd, vehicles traveling east will be limited to a right turn only onto 8th Ave. This change relieves congestion on Mistletoe Blvd. and more importantly will prevent the types of crashes we’ve seen far too frequently. The project also includes an enhanced mid-block crosswalk across 8th Ave to protect the increasing number of pedestrians. The addition of a median in 8th Ave will provide a safe haven between the busy traffic lanes. Changes at the Cooper intersection will slightly widen the street to add a south-bound left turn lane, alleviating traffic stacking up behind cars turning into the Cook Children’s campus. Other updates include new overhead signals, enhanced crosswalks, wider sidewalks, and landscaping on the eastern side of the street. Construction has begun at Mistletoe Blvd now and should be complete this summer. Construction for the Cooper intersection will start shortly after that. That project will be split between intersection work to be completed in late 2022, and roadside and repaving work closely coordinated with Cook Children’s and completed in early 2023.


A Neath-based company has just become the only UK company to receive the industry stamp of approval for a product that could reduce heating bills by 90% and cut the time it takes to build a house down.
JG Hale Construction has just received approval from the British Board of Agrément (BBA), the body that guides the construction industry around which products to use, for an insulated panel product called Trisowarm. Although similar products exist, Trisowarm is the only one with industry approval, now making it a viable choice for housing developers.
If you’re wondering what Trisowarm is and why it’s exciting, the basic idea to grasp is that it’s a product that uses the same chemicals as regular insulation panels but crucially, comes in foam form.
This is highly effective, as the foam can be injected in the factory in between the timber frame panels which form the interior structure of a house, enabling it to get into every nook and cranny. Combined with super tight fitting joints which hold the timber panels together, this makes houses draught-proof and conventional central heating no longer necessary.
Jonathan Hale, Chairman of Hale Construction said:
“Trisowarm makes a significant different to a home’s carbon credentials as it enables you to future proof the energy performance and thermal efficiency of a house from the start. And just as importantly, people don’t live in homes with cold spots lying in wait.”
Tests by Swansea University have also shown that timber panels bound by Trisowarm can withstand pretty much anything. This means they could form the main structure of a house, replacing our current approach of building a home with bricks – they would just need to be clad for appearance’s sake. As a result, houses could be created almost entirely in a factory and then assembled on site, thereby cutting out weeks of dead time when construction is held up due to inclement UK weather.
As Jonathan explains:
“The biggest problem in the UK is the weather. If it’s pouring down with rain, we can’t plaster or do a number of things. But by using Trisowarm, we could design a house and get it water tight within a two-week period.”
This brings a new perspective to the UK’s concept of pre-fabricated houses, currently based on the peculiar looking concrete and steel boxes that popped up after the Second World War and its blitzes. They’re undoubtedly the sign of a time but conversely, making a house in a factory with Trisowarm, means homes could be updated and modernised as often as kitchens are by just changing the outside cladding. And of course they’re built to last forever.
“In the UK we think an Englishman’s castle is made of bricks, but it doesn’t have to be. In Scandinavia, North America and Canada for example, homes are traditionally made in a factory before being put up. It makes a lot of sense – it’s just a change of mind-set.”
At present, Hale Construction creates enough panels for 12 homes a week. Unsurprisingly as fuel prices go up and winters get


Euroconstruct outlined – at its 96th Construction Market Forecast Conference in Dublin on 1 December 2023 – a contraction
in construction across most member countries in 2023 and 2024, influenced by inflation, higher rates, and reduced demand.
Residential sectors are particularly affected, with total new housing expected to decline to 2016 levels by 2025. However,
civil engineering is anticipated to remain robust due to public sector investments in critical infrastructure. Forecasts point
to a slight recovery in total European construction in 2025 and 2026 as the macroeconomic environment improves.
Euroconstruct, the construction market research network, has adjusted downwards its forecast for the European construction
sector for 2023 and 2024 due to changes in the economic environment. The factors explaining the gradual slowdown in growth
and leading to a decline in construction spending in 2023 have become more entrenched since mid-2022, such as the weaker momentum
of the global economy, inflation, the change in direction of monetary policy and the resulting rise in interest rates. The
latest forecast now predicts a 1.1 percent decline in construction volumes in 2023, followed by a further 0.7 percent decline
in 2024. The lecture discussed the implications for residential, non-residential and civil engineering construction and outlined
the scenario for European construction up to 2025.

Project implementation (or project execution) is the phase where visions and plans become reality. This is the logical conclusion, after evaluating, deciding, visioning, planning, applying for funds and finding the financial resources of a project.
The detailed design, tendering, and construction of the infrastructure will take place during this step. Depending on the situation and the complexity, the project might be implemented through a formal construction contract or a voluntary community approach.
“The basic requirement for starting the implementation process is to have the work plan ready and understood by all the actors involved. Technical and non-technical requirements have to be clearly defined and the financial, technical and institutional frameworks of the specific project have to be prepared considering the local conditions. The working team should identify their strengths and weaknesses (internal forces), opportunities and threats (external forces). The strengths and opportunities are positive forces that should be exploited to efficiently implement a project. The weaknesses and threats are hindrances that can hamper project implementation. The implementers should ensure that they devise means of overcoming them.
Whatever method is selected, the construction and installation activities must be carried out under the supervision of experts and engineers. “The level of supervision required will naturally depend on the complexity of the construction work. However, if the design includes any engineering specification, then qualified staff should be available on a full-time basis to oversee construction of the works. The quality of work will suffer if supervision is inadequate because corners may be cut, inferior materials used, and safety compromised.” The involvement of the designers is also needed during the construction stage, particularly to answer questions and make changes in the design when improvements and adaptations are required.
ESPCo has reliable and efficient site engineers who interpret designs and bring them to life on site. The site engineers are very experienced in engineering construction and uphold the highest standards of quality control on site.


Unlike traditional traffic control systems, smart technology for traffic control are much less reliant about human engagement. They can discover live targeted traffic and examine it in real time. They are also better and can reduce traffic congestion. They may have the ability to adjust transmission timing depending on variable elements.
Smart traffic lights may reduce idling by approximately 30 percent, minimizing wait days by as much as forty five percent. Additionally they can help decrease congestion by simply adjusting signal timing based on volume of vehicles. Additionally, they can help give protection to others by simply changing indicators to prevent dangerous drivers by approaching the intersection. They are also built with sensors and connectivity systems to identify live visitors.
Smart signals may be used to manage pedestrian crossings and pedestrian crossings can be enhanced by the traffic light duodecimal system. This procedure combines info from connected road system, connected automobiles, and neighboring traffic lights. Their detection functions allow it to distinguish crossing lanes and reverse driving.
Smart traffic control has changed the way in which we travel around. In some cases, they have reduced travel and leisure times simply by up to 40% and emissions by about 21%. It also prioritizes technologytraffic.com/2021/12/29/generated-post-3/ public transfer. It can also talk with connected automobiles and telematics systems.
An example of a sensible traffic mild is the InSync system, developed by Rhythm Architectural. It has been working at a couple of, 300 targeted traffic signals in the U. Beds. as of November 2015.
Sensible systems also can help deal with targeted traffic better. They can boost the efficiency of intersections and reduce the time this will take for emergency vehicles to achieve their areas. They can likewise help improve fuel efficiency and reduce costs.
In addition to improving traffic flow and safety, brilliant systems may also greatly increase the well being of downtown communities. For example , if visitors is slowed up in a down-town area, it might be better for earliest responders in order to access the location. Smart systems can also increase the quantity of available auto parking spaces.
Clever traffic light systems are capable of control data within the edge on the network. In addition , they are able to present predictive algorithms that will help find successful solutions to traffic management problems.
Intelligent visitors control and smart targeted traffic lights can assist improve traffic and essential safety, as well as maximize parking availability. They can also create options for new marketplace entrants.
Good technologies just for traffic control will help develop more effective city environments. They will help prevent bumper-to-bumper traffic and keep tracks safe. They can also reduce travel times and over-crowding costs.
Intelligent traffic control systems can function with telematics systems and connected vehicles. They can also work with cloud-based transport management systems. They will also carry out predictive analysis and advanced modeling. They can help local authorities develop transport systems that are effective and effecient. They can also work with manufacturers and coverage makers. Intelligent systems can help transform down-town centers. These kinds of technologies will be necessary to keep songs safe in dense locations.

£17m sustainable urban drainage project, designed to capture rainwater and channel it into the river Thames, has been proposed for the Nine Elms South Bank regeneration area…
The biggest sustainable urban drainage system (SuDS) in the UK, an ambitious new project designed to dramatically cut the amount of clean rain water mixing with sewage, is set to be launched this summer across the Nine Elms South Bank regeneration area.
Rainwater landing on an area the size of 20 football pitches will be channelled back into the Thames to stop it entering the capital’s overstretched sewers where it would mix with raw sewage.
This will reduce flood risks and save the huge amount of energy and cost involved in treating rainwater after it combines with waste from sinks, toilets and washing machines.
The £17m scheme has been developed through an innovative partnership between Thames Water and the Nine Elms Vauxhall Partnership, which includes Wandsworth Council, Lambeth Council, the GLA and local developers including Ballymore.
New developments in Nine Elms have pioneered design features in new buildings and landscaping that capture rainwater, and increase evaporation before directing flows to a surface water network.
The rainwater will then drain into large underground pipes buried beneath the new Nine Elms Park which will be a new green channel through the area from Vauxhall to Battersea Power Station.
After heavy rainfall the water will be gradually pumped from this underground reservoir into the Thames via an upgraded pumping station in Ponton Road.


Girders Going Up on Bridge
Bridge girders, the horizontal beams that will support the new roadway, are being placed on the Billings Bypass Yellowstone River Bridge. The new bridge will consist of 112 girders constructed of weathering steel, which provides a protective coating that does not require painting. The girders are being placed on the concrete bridge piers that were constructed earlier this winter. The temporary bridge will be removed once the new bridge deck has been built. Wadsworth Brothers Construction is building the bridge and are planning to be mostly complete by the end of 2021. The bridge will provide motorists, bicyclists and pedestrians a connection between Lockwood and the Billings Heights.

Most existing buildings are affected by various “pathologies” that derive from the methods, materials and building systems originally used in their construction, now totally inadequate in today’s energy conscious climate. As a result they are “energivorous”, consuming up to 20 times the energy necessary to power and heat new buildings. Most existing buildings are in very low energy classes (F and G), and this means high energy bills for the users. The EPDB (Energy Performance of Buildings Directive) 2010/31/EU clarifies, reinforces and widens the scope of the Directive 2002/91/EC. The EPDB recognizes that energy certificates are the first step towards sustainability in existing buildings, providing a first assessment of their efficiency in terms of energy use. It emphasizes how the performance improvement proposals indicated in energy certificates provide an important basis for energy renovations. The activities carried out in an energy assessment bear close relation to those required in an energy audit. Energy assessments are useful in providing a first “diagnosis” of the building, helping us to understand its “state of health” in terms of energy consumption. Energy certificates usually contain brief indications on proposals to improve the buildings energy performance, including retrofits to building systems, thermal insulation of the building envelope, and the use of renewable energy sources. The calculation procedures used for energy certificates are based on standard parameters (external and internal temperatures, hours of operation of heating systems, etc) and so do not tell us the exact amount of energy that a specific building actually uses. Energy certificates are obligatory for the sale and rent of properties, for new constructions or major renovations and retrofits/substitution of building systems, and for access to tax reductions and financial incentives.

PORT ANGELES — The city of Port Angeles is seeking state funding to design fish passage improvements that could provide salmon habitat along 5.4 miles of Ennis Creek.
The City Council voted unanimously last week to authorize a $191,260 grant application to the state-administered Brian Abbott Fish Barrier Removal Board.
The city would use the grant to design the removal of two side-by-side concrete barriers on the lower creek and a portion of an abandoned combined sewer overflow interceptor main that was installed under the creek in 1969 and is now exposed across the width of the stream.
“Removal of those barriers is pretty significant from an environmental standpoint,” Public Works and Utilities Director Thomas Hunter told the City Council on May 19.
“This grant will provide us 100 percent design for removal of those fish barriers, and we’re really excited about it.”
The existing double-concrete culverts under Ennis Creek Road about half-mile from the mouth of the creek will be replaced with either a bridge, a wide concrete box culvert or an arch culvert, according to the city’s preliminary 2021-26 capital facilities plan.
The 1969 sewer main, which is just downstream from the Olympic Discovery Trail bridge, was taken out of service in September 2016 when the city completed its combined sewer overflow project.
Ennis Creek fish barrier removal is listed as a $950,000 project in the capital facilities plan.
The city project will coincide with a state Department of Transportation effort to replace another culvert for Ennis Creek under U.S. Highway 101, Hunter said.
“I’m excited to be moving forward on what could be the eventual restoration — complete restoration — of Ennis Creek,” Mayor Kate Dexter said in a virtual council meeting last week.
“I think that’s pretty exciting.”
Council member LaTrisha Suggs, a restoration planner for the Jamestown S’Klallam Tribe, said other groups like the North Olympic Peninsula Lead Entity for Salmon have been working with the state to identify culverts that need to be replaced.
“This just helps in that overall bigger-picture process,” Suggs said.
“So this is just one of those great, fun projects to work on.”
Ennis Creek begins on the upper slopes of Klahhane Ridge and flows about 8.7 miles to the Strait of Juan de Fuca.
The creek supports steelhead, coho, bull trout and cutthroat trout, Hunter said in a memo.
“It is the healthiest of the seven Port Angeles urban streams with the largest undisturbed upper watershed with headwaters in the Olympic National Park,” Hunter said.
“It has the least development, the greatest diversity of existing native fish stocks and the highest potential for restoration and salmon recovery.”

The Colorado Department of Transportation (CDOT) estimates the adaptive signals it installed on U.S. 34 Bypass and U.S. 85 near Greeley have cut travel times enough to save travelers through the corridor about $5.8 million on an annualized basis.
Adaptive signals change timings on actual travel demands rather than through set parameters using a combination of hardware and software technologies. CDOT installed the signals in fall 2015 for roughly $800,000 coming from the Responsible Acceleration of Maintenance and Partnerships funding.
“We have come a long way with technology at CDOT,” says Regional Transportation Director Johnny Olson. “This type of innovation has great benefit to the community. This is one way were are getting more out of our existing roadway system at a low cost.”
In a recent study, CDOT found travel time was dropped by 13 percent on the U.S. 34 Bypass and 23 percent on U.S. 85, saving about 829 hours per day. This also reduces the number of stops on the corridor—89 percent on U.S. 85 and 51 percent on the U.S. 34 Bypass.
CDOT says this extrapolates out to 20 million fewer individual stops in a year, a figure it converted to a carbon monoxide emission reduction of 17,850 pounds, carbon dioxide emission reduction of 2.3 million pounds and hydro-carbon and nitrogen oxide emission reduction of 4,550 pounds.
Add up the fewer stops and starts for motorists and CDOT says 318 gallons of fuel are being saved on both roadways. At an average of $1.75 per gallon, that equates to $194,600 per year in savings.
“The success of adaptive signals on the 10th Street corridor was the catalyst for implementing adaptive signals on these two additional highways in the City of Greeley,” says Larry Haas, traffic operations engineer at CDOT. “Our goal is to move traffic efficiently and safely. The results of the study proved what we hoped which is we are able to get people on their way quicker and safer which is better for everyone.”
CDOT says it plans to add adaptive signals to U.S. 287 and Colorado 119 in Longmont beginning this fall.

CRINA BUCUR, RELU DOBRIN, MIRELA OLTEANU, MARGARIT PAVELESCU, CARMEN CRISTACHE RADIOCARBON SORPTION ON LOESS AND IMPROVED LOESS SAMPLES
14C sorption characteristics on the natural loess sampled from Saligny site and on mixtures of loess with different percents of Portland cement and Na type bentonite were determined performing batch sorption experiments. These experiments showed that while the bentonite added to the natural loess has a negligible effect on 14C sorption, the low 14C distribution coefficient on the natural loess is considerably improved by the Portland cement added to the loess. The values of 14C distribution coefficient increased from 2.06L/Kg for natural loess to 42.40 L/kg by adding 9% of cement to the natural loess. This could have an important effect on the radiological impact due to the 14C waste disposal on Saligny site.


One of our members has been very proactive in trying to get improvements to the London Road roundabout on the A316. This has no crossing facilities on the exits to the London Road, breaking the cycle lanes on the both the northern and southern sides of the A316. These discontinuities act as a significant barrier on one of the busiest roads in the Borough. As well as contacting the Vice Chair of the London Assembly Transport Committee, GLA Member Caroline Pigeon, they have also produced this summary audit of the problem, which illustrates it very clearly:
We shall continue to pursue improvements on this junction with TfL who have responsibility for the A316 along with other areas of concern on the A316.

The SIKA VVX LowFlow is used for the flow measurement in Heatpumps.
Behind a flowed-around bluff body, counter-rotating and mutually offset vortices arise. The vortices detach at the edges of the bluff body and form a Kármán vortex street in the flow. The distance between the individual vortices is constant. The frequency at which the vortices flow past a sensor depends on the flow velocity and is proportional to the flow rate. The sensor detects the vortices, which are converted into an electrical frequency signal.

The Wisconsin Department of Transportation (WisDOT) has created its own customized weather information system to improve efficiency in its winter road maintenance operations. Intended to help contractors decide when to spread salt or anti-icing methods, the roadway weather information system (RWIS) is also useful for helping summer work crews decide when to mark pavement, pour concrete or perform other weather-sensitive tasks. The RWIS consists of a weather forecast and animated weather radar picture delivered via the Internet and satellite to all contractors. The forecast is updated continuously, so users can track weather developments easily. Pavement temperature sensors, some of which are mounted in permanent positions around the state and some of which are strapped to road supervisors' vehicles, supplement the weather forecast with information about actual road conditions.

The proposed redevelopment of 640 Fifth Avenue (Crowell-Collier Building) located on the northwest corner of Fifth Avenue and Fifty-first Street called for the addition of 35,000 sf of unrealized zoning area, the redistribution of the total gfa into a series of more efficient and consistent floor plates and a program to upgrade the 1950s era building to meet or exceed the standards of modern Class A boutique office space. The owner’s desire to find a design solution for the tower and lobby upgrade that could be implemented while the existing building floors three through eight remained occupied was further complicated by the recent renovation of the building’s ground, mezzanine and second floor for a significant new retail tenant. Any new structural loads imposed by the proposed new massing would need to be resolved within the existing structural grid without the need to reinforce existing structure below the ninth floor in tenanted space or impact the existing foundations.
The existing 18-story Indiana limestone building designed by Leonard Shultze & Associates in 1948, to house the Crowell-Collier publishing offices, attempted to relate to the character and scale of the adjacent Rockefeller Center complex. The building’s response to the zoning envelope in the form of a series of convoluted setbacks rendered the building a complex cubic form, in contrast to the more elegant vertical layering of the Rockefeller Center massing. Lewis Mumford suggested that the design was “an example of eclecticism without conviction,” an attempt to reconcile the traditional and the modern that managed “to combine the saddest features of each.” The floor-by-floor varied setback section also resulted in a random mix of oddly-shaped floor plates punctuated by a forest of closely spaced low-capacity columns. The sectional misalignment of the structure relied on a system of deep transfer beams, limiting ceiling height within the office space to 8’-0”. The building’s architecture was interpreted as a missed opportunity in a context that offered significant challenges and even greater rewards. The building’s prominent Fifth Avenue address across the street from St. Patrick’s Cathedral at the northern limit of the Rockefeller Center complex placed it within the center of midtown Manhattan’s most significant public urban space.
The decision to completely bifurcate the material expression of old and new, rendered the existing nine-story limestone base closer to the series of four existing international building podiums of Rockefeller Center that extend out to Fifth Avenue. Within a massing that collages the grain and proportions of the RCA Building, the limestone base is then host to a new jewel-like 12-story glass tower above, that sits in an elevated garden plane, punctuated by the four rooftop gardens of Rockefeller Center. The city is interpreted as a stratified set of distinct horizontal planes with a landscaped platform floating eight floors above the street datum and the lower plaza (skating rink) sitting two levels below a thin ground plane at street level. The relationship of host and visitor is reinforced through the distinct material transformation within this section from heavy limestone cladding with punched openings to a delicate glass and stainless steel curtain wall above. The new glass tower façades, along with St. Patrick’s Cathedral and the Rockefeller buildings, define the new limits of an urban room within which the floating garden plane is suspended. This room reinforces the idea of the city as theater as the movement of Fifth Avenue intersects with the east west grain of the pedestrian open space defined by the Channel Gardens and the lower plaza.
An elegant solution for the tower massing was determined within the original zoning envelope and the existing structural armature. The new tower is comprised of three rectangular transparent green glass volumes defined by a series of vertical layers oriented in the east west grain of the Rockefeller buildings. These layers are defined at the curtain wall surface along the Fifth Avenue facades by vertical mullions with delicate stainless steel outriggers that extend out from the wall. A more subtle horizontal pattern is articulated behind the glass by a corrugated aluminum panel within the shadow box, and the single line of the interior tubular guard rail that floats 2’-10” above the floor level. The east west orientation of the floor plates and the shearing of the two primary volumes maximize the buildings south, and east-facing exposure to the Beaux Arts rooftop gardens below and the Gothic articulated roof and façades of St. Patrick’s Cathedral. The additional two story lower volume receives the extension of the roof gardens in the form of terrace planting layered behind transparent glass parapet walls.
A perimeter deluge sprinkler system was employed at the curtain wall interior to reduce the NYC spandrel dimension requirement to permit a 2’-6” shadow box and an uninterrupted vision glass panel that extends 9’-6” from floor to ceiling to take full advantage of the panoramic Fifth Avenue views. Special effort was taken to maximize ceiling heights within the modest 12’-0” floor to floor structure of the existing building. Detailed plumbing and air distribution drawings produced by the architect permitted the close coordination of mechanical and structural work to achieve ceiling heights of 9’-6” minimum at the perimeter office zone. An elaborate network of beam penetrations and subsequent reinforcing was required to accommodate the new mechanical system distribution within minimum construction tolerances.
The penthouse floor height was increased to accommodate 14’-6” vision glass panels that extend up another 40’ to enclose a lantern that conceals the mechanical and window-washing equipment behind a floodlit corrugated screen wall.

Innovation Zone: SewerBatt
This month, we look at technology which uses acoustic signals to allow the rapid inspection of sewers and drains for serviceability
What is it?
SewerBatt, supplied by Acoustic Sensing Technology, is an acoustic sensing software solution which records data delivered by a probe inserted into manholes or other drainage access points. The technology uses acoustic signals to survey and check the serviceability of pipe networks to rapidly identify defects, blockages and other debris which may cause problems in the future. It is designed to complement the use of CCTV by rapidly surveying pipe networks to immediately confirm that a length of pipe system is clear of debris, or to inform maintenance engineers where to use more costly CCTV or cleansing.
What’s innovative about it?
The technology works using acoustic signals similar to those used by a bat for flying at night. These sound signals can travel around bends and through junctions in the pipe, quickly pin-pointing any obstructions or problematic sections. Via a laptop screen which is supplied with the kit, the operator can see whether a pipe is clear or not, and the exact distance to any blockage.
What benefits does it bring?
Because surveying using SewerBatt is much quicker than CCTV – it can cover 100m of sewer pipe in under three minutes – it saves time by allowing operatives to carry out a ‘first pass’ survey before targeting CCTV or cleansing at the point where it is needed. If jetting the sewer is needed, then SewerBatt can be used to check that a blockage has cleared. The method provides savings in terms of time, and camera and cleaning costs.
Other benefits include minimising heath and safety risks - since the survey can be carried out without having to enter the sewer - and minimising the need for highway notices, as the speed allows the work to be completed under emergency works. It also enables teams to make quicker decisions, because of the short timescales between the survey being completed and the results being available.
How was it developed?
SewerBatt was invented by civil engineer Richard Long, who came up with the original concept in 2002; after gaining research funding in 2005, it was developed as a joint research project between Yorkshire Water’s Innovation Delivery Team and The University of Bradford. Acoustic Sensing Technology (UK) Ltd was formed as a commercial entity in February 2013 to provide the physical technology, software and field support for SewerBatt.
Who is using it at the moment?
Thames Water’s wastewater network partner Lanes Group recently announced it was implementing SewerBatt across the Thames network after an 18-month trial period showed that it could reduce the need for CCTV surveys by 33%. Other clients in the UK water sector include Severn Trent, UU, Yorkshire, Scottish and Anglian Water. It has been used in Australia and there is also interest from the United States.
