Walk On Water in Yankton
Nov 23, 2011
Now the historic bridge will be a pathway for joggers and walkers, baby carriages, bicyclists, skateboarders and the like. It is the longest pedestrian bridge in the USA that connects two states over a major river. The Newport Bridge, an 1896 railroad bridge that links Kentucky and Cincinnati, had that distinction until today. It is 2,670 feet long, and was redone for foot traffic about a decade ago. The Meridian easily surpasses it at 3,013 feet. The third longest is a new structure, the Bob Kerrey Pedestrian Bridge, built to connect Omaha with Council Bluffs, Iowa. It measures 2,224 feet.
Today at 3 p.m. the Meridian Bridge will be re-opened to the public after being closed for three years. But the bridge will never see another 18-wheeler ... and it isn't even likely to carry a compact car.
Eventually, Yanktonians and Nebraskans hope that walking/biking paths will connect the Meridian Bridge to the bridge over Gavins Point Dam, about four miles to the west. A path already exists on the South Dakota side, and Nebraska officials are making plans for theirs. The 12-mile loop would instantly become one of the most unique trails in the USA, taking hikers and bikers past eagle roosts, quaint restaurants, a sailing marina, small farms and forested river bottom. City officials in Yankton also hope to design and build an attractive plaza at the foot of the bridge.
The Meridian is one of the very few double-decker bridges in the nation. It took its name from the Meridian Highway (US Hwy 81) that cuts through the Americas from Winnipeg to Panama City. Yankton citizens took it upon themselves to fund and build the bridge in 1924 because they thought state officials were too slow in getting the project started. They paid for it with tolls until the debt was retired in 1953.
The bottom deck was intended for rail traffic, but a north-south train route to Yankton never materialized, so officials sent northbound traffic on the top and southbound traffic below. Its classic towers were designed with hydraulic lifts to allow ships to pass underneath. However, ships have been as rare as trains.
Cars and trucks traveled the bridge to the tune of 5,000 or more a day until a new bridge was completed in 2008. Historians on both sides of the river objected to having the old bridge destroyed. In fact, local leaders agreed that they would settle for a plain design on the new bridge so long as the savings were directed to preserving the Meridian as a footbridge.
So beginning this Thanksgiving week, after a very long wait and $4 million or more of your tax dollars, the old Meridian will once again carry traffic. Now you can walk on the Missouri without getting your feet wet.
We hope to see you there.


For ages, trade, tourism, and travel across diverse bodies of water have all been made possible because to water transportation.

Delta Bravo AI
TURN MONTHS OF WORK INTO MINUTES.
Delta Bravo AI automates the hardest parts of data science, reducing the time and cost to deploy Machine Learning and AI capabilities.
Delta Bravo AI simplifies your process from the start, curating a series of algorithms proven to work.
AMERICA’S SMARTEST CITIES USE DELTA BRAVO
We work with towns and cities across the US, applying Machine Learning and AI to improve public safety.
Cities have proven adept at collecting data; from meters, sensors, traffic lights and countless other sources. But how many are using this data to improve public safety and amenities for residents as their municipalities grow? Delta Bravo’s Smart Cities Framework offers a fast and affordable way to get started. Common uses of our Smart City framework include:
As cities and towns grow, law enforcement and traffic safety resources don’t always grow with them. We’re working with cities and police departments to leverage data that’s already being collected to improve traffic flow and put limited traffic safety resource where they need to be.
The City of Rock Hill, SC is adjacent to Fort Mill, SC- one of the fastest growing towns in America. Using data from traffic lights, historic traffic flow and accident data, past and forecasted weather data and city event information, we’re able to identify what intersections have the highest likelihood of a collision throughout the city, within a 4-hour window, down to the percentage likelihood.
This removes anecdotal decisions and helps traffic safety resources be in the right place at the right time. The next step for this capability is to improve traffic light patterns for safer ingress and egress throughout the city.
Civic Unrest Detection
Do you Know the Tipping Point for an Oncoming Emergency? Delta Bravo’s ability to understand photos and videos greatly helps in processing the mountains of data from surveillance systems or for “pattern-of-life” surveillance. Typical elements, activities and actions are modeled and analyzed so any unusual behavior or anomalies ranging from movements and gatherings to lighting conditions are detected and alerted on. This capability can be applied to high-transit locations or targeted areas for civic event coverage and more.
Optimized Emergency Response and Evacuation
Delta Bravo makes public infrastructure dynamically responsive to emergency scenarios. We are working with a city right now, leveraging forecasted flood plain patterns to adjust traffic signals for efficient evacuation of civilians and faster entry for emergency response teams. Delta Bravo can also compare and optimize human developed courses of action (COAs) alongside computer generated courses of action including the criteria for suitability, feasibility, acceptability, uniqueness and completeness.
Safer School Zones
Delta Bravo is working with a municipality today to combine License Plate Recognition data with Known Offender data to alert area officers when the wrong people are in the wrong places. Recently, this system alerted local officers of the presence of a known child predator in a school zone. It was also used to alert patrol officers of the presence of gang members in hostile territory. Officers arrived on the scene to defuse a potentially violent incident before it happened.
Improved Traffic Flow and Parking Management
Delta Bravo can ingest data from road sensors and traffic lights to built models for Adaptive Signal Control designed to reduce transit times and improve safety. This capability is estimated to reduce travel time by 25%, decrease vehicle stops by 25% and wait time by 40%. It is also being used to improve transit time for First Responders. Delta Bravo can also be used to process license plate recognition (LPR) data, alerting parking management teams to current or future violations. This technology can also be used to forecast when available parking zones will be filled during civic events for better routing of traffic to available parking.
Better Management of Water, Electric Resources
Delta Bravo processes data from disparate sources, such as pumps and filtration systems, through its algorithms to come up with optimal management and control protocols. This enables water managers to conserve energy, lower operating costs, and squeeze more life from water plant assets. AI can also be used to automate the inspection of sewer systems or the accuracy of meters. The same principles can be applied to municipality-run electrical grids and utility systems.
Delta Bravo Frameworks leverage reusable, proven elements from successful AI engagements to get projects moving quicker while retaining the flexibility each unique customer needs.


TitleAnalysis of mechanical properties of spatial truss structures sections
AuthorsS.A. Zommer, A.P. Kravchunovsky
OrganizationJSC «Academician M. F. Reshetnev» Information Satellite Systems»
Zheleznogorsk, Krasnoyarsk region, Russian Federation
AbstractThe paper presents the results of computational study of sections of spatial truss structures. They can form large supporting structures on spacecraft to place onboard equipment. The calculations were carried out by the finite element method in FEMAP with Nastran. The chosen section, the object of study, is a set of straight rods rigidly connected at the nodes in such a way that the cross section of the truss structure is a triangle. Calculation models, procedures for calculation and results analysis are presented. The purpose of the calculation is to determine how the relative position of the rods in the structural scheme affects the mechanical properties of the structure. The main criterion for strength estimating was the magnitude of the stresses derived by load. Stiffness was determined by the value of the first natural frequency. The sequential addition of rods and varying their connection allow modifying the structural schemes of truss structures. Next, the mechanical properties of the structure which effected by made modifications were evaluated again. Thus, six structural schemes of sections of the truss structure, obtained from the results of the study, have been developed. At the same time, the mass of the section, its shape and dimensions, the material and shape of the rods section as well as the initial and boundary conditions, remained unchanged. Based on the results of the analysis, someone can notice that each structure has unique mechanical characteristics. Thus, the paper gives recommendations for choosing a specific structural scheme of the section, depending on the required operating conditions and acceptable manufacturing technology. So, the criteria for choosing one of the above various sections of a truss structure or the principle of its building can be the complexity of manufacturing, maximum stiffness and strength, or minimum displacement. Structural schemes of sections with the highest strength and capability have been selected for use as part of spatial truss rods of spacecraft.

The next stage of Cheshire East Council’s active travel schemes is set to press ahead.
Tomorrow, 9th March, the authority’s cabinet will meet to discuss the approval of the borough’s Local Cycling and Walking Infrastructure Plans (LCWIPs) — covering Crewe, Congleton, Macclesfield, and Wilmslow.
The plans are not fully funded yet — meaning work will not begin on the projects until money is found — but the documents will play a pivotal role in the future of cycling provision, CEC says.
A pre-meeting report said: “The adoption of the LCWIPs will provide a strategic approach to the Council’s investment in walking and cycling infrastructure from both internal budgets and external funding sources.
“The Department for Transport has noted that LCWIPs are not mandatory documents but that local authorities who have plans will be well placed to make the case for future investment.
“Therefore, not developing LCWIPs would likely result in avoidable constraints for securing external funding. Additionally, failure to develop a strategic network plan may lead to future investment being uncoordinated and poorly integrated.”
It added that the funding to construct the infrastructure schemes would be drawn from existing council budgets, ‘and external sources such as Department for Transport specific grants or developer contributions’.
The plans indicate a raft of changes to road usage across the four towns.
In Congleton, a new segregated roundabout could be built on Rood Hill, and a shared ‘informal street’ scheme would be installed on West Street, near the town centre.
Further north, in Wilmslow, advisory cycle lanes on Manchester Road would be upgraded, and Macclesfield would see north-south connectivity improve with traffic calming.
The largest changes are set for Crewe, which would see a new route to Leighton Hospital, a low traffic neighbourhood, and a town centre loop implemented.
CEC Cabinet will discuss the plans in a virtual meeting at 1pm on Tuesday 9th March.
You can view the plans online:

Passive House, Energy-Efficient or Eco-House is a modern response to depletion of natural resources and the cost of utility bills. In the non-energy efficient houses heat loss occurs through poorly insulated walls, roofs, windows, and doors. A Passive House is constructed to retain heat inside in the winter and keep it out in the summer. The way a passive house operates is through maximum reduction in heat exchange with the environment. Energy efficient house should minimally dependent on foreign sources of energy and use its own energy — the energy of the sun and the people who live in it. The special structure of a passive house allows a person to be closer to nature and the earth.
- The first things to consider when designing a passive house are its location and surroundings. Exact calculations of natural energy is the first step.
- Glazing should be based on the selection of advanced types of energy-efficient glass, insulating glass with high thermal conductivity, multi-core systems, and strategic placement of windows.
- Glass area should be optimal with respect to the necessary level of natural lighting and insulation.
- Terraces, loggias, balconies should be designed promote the flow of light, as well as provide additional protection from cooling the building in winter and overheating in summer.
- The types of windows and installation of additional air ventilation should be well thought out.
- Installation of solar panels as well as special blinds to protect from direct sunlight also play a big part in energy efficiency.
GlazingGlazing plays a big role in the construction of a passive house, because windows and doors should provide the best possible natural lighting. In this case, the windows must withstand wind and other mechanical stresses to be energy efficient. A special coating on the glass allows you to monitor the degree of lighting by dimming the amount of incoming solar heat or reflecting it. Glazing technologies offer different engineering solutions, including automated integration with electrical components. Multi-functional glass complete with warm profile systems are able to provide the proper distribution of energy.

We have received questions and have seen comments on social media that there may be a need to issue a "boil order" for drinking water due to the recent floods. In response, the City of Florence or anyone else that I am aware of, has not experienced any issues treating drinking water during the recent flood, or floods in the past. Modern drinking water plants are designed to treat water under the most extreme conditions. Our certified treatment plant operators are also well trained to operate these facilities.
ANY UNSAFE CONDITION THAT WOULD REQUIRE A "BOIL ORDER" WOULD BE ISSUED THROUGH MULTIPLE MEDIA OUTLETS, NOT JUST SOCIAL MEDIA.

Building a bridge is a special arm of construction, which involves intensive and more specialized labor. Here, you need a company that has all the different construction specialists from the scratch to completion of the entire project. Some construction companies may be good in some aspects but poor in others and that’s why you need to take time and look for the most reliable.
Here are some factors to consider when hiring these professionals.
How is their work relationship?
Find out whether the company has been able to maintain a good working relationship between the planners, builders and the engineers in order for them to perform optimally. Any company whose teams are disjointed will lead to an aborted project and you are the person to absorb the loss in case of delay or where you have to fire and source for a different construction company. Talk to company management and get feedback from previous clients.
How has the company performed before in their service? Probably you’d hired them before, how did they perform? The construction company should be able to move with speed and be precise in rendering service. You don’t want to work with a team that will keep giving excuses due to non-performance and ultimately lead to delay and unbudgeted costs. Let the company commit that they would hand over the finished project within the set timelines and in case they delay, they should commit in writing, that they’ bear the extra cost.
The first step before construction is planning. This is what creates the picture of the finished product on paper and the step-by-step process of accomplishment. The construction company should have the expertise in laying out a clear plan of how they are going to complete every task and the timelines for each step. This will enable you to prepare for the necessary materials, the labor payments among other logistics. Planning gives you the end in mind and thus no surprises.
Does the construction company have the right licenses?
A legitimate company will have a certificate of registration and a license from the relevant government authorities. This would prove that they are fit for the task and would perform the work professionally. Without the license or registration documents, don’t even think twice about such a company because it may mean a world of problems to you. A license is what binds the company so that they don’t run away in the middle of the project or even con you.
Engineering and architectural services
You need professional and efficient bridge construction services and therefore, you must get a good company like Bridge Brothers with the right people. Architects and engineers work closely to get the construction in tandem with the drawn plans for the project. Without any of the above, you may incur a cost in hiring a different company, which is an extra cost.
Remember, building a bridge is a hefty investment. Thus, you can’t just rush into getting any construction company without a thorough check. You need an efficient company for excellent work within the agreed timelines.

Italian Company Signs US$124m Contract for Road Construction in Cameroon
Italian Company, Seas, has signed a contract for construction of the 70km Olounou-Oveng road in Cameroon.
This commercial contract will allow Seas to participate in phase I of the Olounou-Oveng-Gabon border road construction in Cameroon. In mid-February 2021, Minister of Public Works Nganou Djoumessi Emmanuel signed a commercial contract with the Italian company Seas in Yaoundé. Seas was represented by its General Manager Francesco Pauseli. This road project spans over 105 kilometers and is projected to cost XAF67 billion (US$124 million). After signing the commercial contract, the next step will be the public contract’s signature by the State of Cameroon and Seas. The construction phase is estimated to last for 24 months, and the road is planned to be 3.5 meters, 1x2 lanes, with a reference speed of 60km/hr. Other road features will include 59 cross drainage structures, 13 bridges of various lengths, crossroads, and horizontal and vertical traffic signals. The financing of this project, which is a significant point in the commercial contract, includes technical and geotechnical controls, a weighing station, the construction of an automatic toll station, and a counting station. Italy expressed its interest to finance this project back four years ago during the business forum held on the sidelines of President Paul Biya’s state visit to Italy in March of 2017. A memorandum of understanding was then signed that specified that the Italian companies Seas, Italfer, and Leonardo Group will carry out the construction work. Out of the three, only Seas will see the project to fruition. According to the Ministry of Public Works, this axis was chosen as part of the road component of the Triennial Emergency Plan for the Growth Acceleration (PLANUT). This was significant because of the desire to open up production basins by connecting each of the cities that are part of this project to the structuring network.

Atlantic Council’s Strategic Foresight Initiative
The greatest challenge for engineers will be developing and deploying more resilient solutions at scale….
Call me a pessimist, but I believe engineers will be in a race against time and climate change to replace destroyed and failing 20th-century infrastructure—roads, power lines, pipelines, etc—with new technologies, materials and networks out of necessity.
Hurricane Sandy in 2012 not only exposed the weaknesses of America’s coastal infrastructure, but also the inability of local governments to afford replacements in the face of increasingly frequent storms. Meanwhile, the back-to-back-to-back typhoons Pablo, Yolanda and Glenda in the Philippines exposed just how difficult it will be for developing nations to physically rebuild ahead of the next storm.
The greatest challenge for engineers will be developing and deploying more resilient solutions at scale, whether that be solar micro-grids, new transportation alternatives and, (hopefully), cheap, transformative infrastructure that hasn’t been invented yet.


Dam Saves $2 Billion
January and February brought a lot of snow to the Mid-Atlantic states. In fact, record-breaking snows in the “all time” category fell near and far across the region. Not too far from the Mid-Atlantic, off to the northwest a bit, is the shoulder area between the Great Lakes and the Mid-Atlantic: Pennsylvania and, more specifically, western Pennsylvania.Western Pennsylvania was on the receiving end of many of the Mid-Atlantic snows in 2010, more or less, depending on the storm. But western Pennsylvania was also on the receiving end of many of the infamous lake-effect snows from the Great Lakes. Again, “more or less” depending on the storm. However, certain regions of western PA certainly had residents wondering, “Snow? Again? C’mon, March!” Well, March is here and all that snow is melting. Making a bad situation worse, rain has been in the forecast for this region for the past few days and is expected to continue. Flooding from rain and snowmelt now falls to the flood control programs in place across western PA.

In 1952 the Conemaugh River Lake Dam was completed. Designed to prevent flooding to the lower Conemaugh Valley, the Kiskiminetas Valley, the Lower Allegheny Valley and the upper Ohio River Valley, the lake/dam is one of 16 flood control projects in the Pittsburgh district. When rainfall, melting snow or accelerated stream flows indicate the possibility of flooding, the dam retains the additional water until it can be released without flooding regions downstream of the dam.

Authorized by the Flood Control Acts of 1936 and 1938, the Conemaugh River Lake Dam is one of many Flood Control and U.S. Army Corps. of Engineer projects across the United States. Since its completion, it is estimated that Conemaugh has saved more than $2 billion in flood damage. It’s estimated that $375 million in flood damage was prevented when the remains of Hurricane Ivan visited the area in 2004 with between five and nine inches of rain — most of which fell during long periods of heavy rain.

Rehabilitation is not only science but art. Retrofitting should not be attempted before understanding the problems involved in that particular building. If the building is damaged, the cause of damage should be clearly identified prior to retrofitting. The choice of retrofitting technique depends very much on the nature of problems involved, architectural restrictions and functional requirements. It is also important to know the cost of interrupting the functionality. In some cases cost of interruption can be the determining factor in selecting the retrofit technique to be used.

Support Community Development
Community-based projects are proposed by local community councils in coordination with their regional CRIPDES team to address development or infrastructural needs as perceived by the people who live there. These projects may range from $100 to $10,000, and can include anything from organic vegetable gardening projects to constructing a new potable water system.
Such projects are identified by the community’s board, analyzed and executed by the CRIPDES promoters.
It is our goal that all of these projects help with the organizing efforts and education of rural communities. We actively aspire to support on-going efforts instead of imposing an external solution.
You can read some of the projects we have been involved with here.

When you have a concreting service pour fresh concrete on your property, you may not think to ask how to take care of it once it's poured and as the years go by. Concrete is very durable but it's not indestructible, so it's vital that you know how to maintain it and keep its strength from being compromised after being poured. Note a few questions you might have about fresh concrete on your property and then be sure to cover these with your concreting service so your area lasts as long as possible and always looks its best.
What is curing and how long should it be done to fresh concrete?
Curing refers to putting something over fresh concrete to protect it and allow it to set; this might include straw, plastic, special blankets meant for concrete, and the like. This covering keeps out excess moisture that can soften the batch of concrete and also protects the surface from twigs, branches, and anything else that might make a permanent indentation.
The time period for curing concrete will vary according to the mixture, the depth of concrete, and even local weather conditions. Don't assume that the time your neighbor kept the plastic over their new concrete driveway is what your driveway needs, but check with your concrete pouring service for how long this curing should take place on your property.
How long before new concrete cracks?
All concrete cracks over time; it will absorb moisture and then expand, and then contract as it dries, causing cracks. Heavy traffic also puts pressure on it so that the surface eventually cracks. There is no "one size fits all" answer to this, but be sure to ask your concreter about how long fresh concrete should last. If it starts to crack before this, you might need to have your property graded or sloped to keep moisture from collecting under the concrete. You may have also opted for a very cheap mixture and depth of concrete that isn't strong enough to withstand your heavy caravan or other such wear and tear.
Ask how to clean the concrete
Concrete might have an aggregate, which is a material added to the surface to give it texture and color. Cleaning this with a stiff brush or certain chemicals might damage the aggregate, even though the chemicals say they're safe for concrete. Certain cleaning products might also damage painted concrete. To ensure your newly poured concrete looks good for years to come, ask about how to clean it and keep it looking fresh.


The domestic hot water cylinder is often seen as a permanent fixture in the home. However that is not always entirely true. It may be that your current hot water system is in need of an overhaul or perhaps an upgrade. Perhaps you are embarking on a new build or house renovation project. In any of these scenarios, you will need to make choices about the design of the hot water system and one decision will be whether to choose between a vented and unvented heating system. In this article we will explain the difference between the two types of hot water systems..
What is an Unvented Hot Water Cylinder
As Mr Scot, the chief engineer from Star Trek taught us, “you can’t defy the laws of physics”. The fact is that when various materials are exposed to heat, they have a tendency to expand. You may wish to read up on Charles’ law which explains the principle.
This is especially the case when we consider a hot water cylinder, where the water itself as well as the air on top of it, needs to have a potential escape route to prevent too much pressure building up and causing damage.
There are a number of ways of achieving this safe reduction of pressure. As its name suggests, an unvented hot water cylinder is a sealed heating system. There is no water tank in the loft. Instead, water to be heated is fed into the water tank from the mains supply and heated by the electric element or a heat exchanger coil from the boiler.
Since the system is effectively sealed, there has to be a mechanism which allows the pressure to be safely relieved as the water in the cylinder is being heated. This is achieved by using a device called an expansion vessel. An expansion vessel is a sealed chamber fitted with an internal flexible membrane which stretches to allow for the increase in pressure by up to 4.5%, thereby reducing the risk of damage to the heating system.
Pros and Cons of Unvented Hot Water Cylinders
Here are some facts which you should be aware of before you choose your domestic hot water system.
- No water storage tank in the loft is required as the water supply is directly from the mains.
- This gives a much wider choice when it comes to the location of the hot water cylinder.
- With no water storage tank in an unheated roof space, this also means that there is very little risk of the water freezing or becoming contaminated.
- With no tank of water feeding the cylinder, the unvented cylinder is much quieter in operation than in a vented system.
- Unvented hot water systems are relatively complicated so maintenance and installation can be costly.
- Expansion vessels have a limited lifespan, usually around 10 years, before they need to be replaced.
- There is no cold water tank in the loft which means that there is no reservoir of water if the mains supply is turned off.
- Unvented heating systems may not supply enough water pressure for modern power showers, or sufficient flow for some types of mixer tap..
What is a Vented Hot Water Cylinder?
Unlike in the unvented system, a vented hot water cylinder is not entirely sealed. They are also known as ‘gravity fed’ cylinders as the water supply comes from the cold water storage tank in the loft rather than from the mains. Instead of the excess pressure being relieved by an expansion vessel, the water is allowed to flow up an open vent pipe, back into the storage tank. This can lead to a certain amount of heat loss, although good insulation around the tank and pipes helps to reduce this.
Pros and Cons of Vented Hot Water Cylinders
As with the unvented cylinder, vented cylinders also have advantages and disadvantages.
- The vented system is considerably simpler than the unvented system, so there is less to go wrong, particularly as there is no expansion vessel in place.
- The vented system is therefore cheaper to install and to maintain.
- There is a ready source of cold water to the system even if the mains supply is disrupted, in the form of the cold water tank in the loft.
- The water pressure is dependant on the height of the water tank above the taps. So it follows that in any building with more than one storey, water flow will be more powerful from taps in the lower floor than those at a higher level.
- Because of this variation in water pressure, it may be necessary to fit a water pump in order to boost water flow, which adds to fitting and running costs and potential maintenance issues.
- The requirement to have a water tank in the loft means that more space is required for a vented hot water cylinder and as a result, the options for locating it are also reduced.
Should I buy a Vented or Unvented Hot Water Cylinder?
As we have already seen, there are both advantages and disadvantages with both types of hot water cylinder. It should be emphasised that if your home is already fitted with one type of cylinder and it is performing its job of supplying hot water adequately, there is probably no need to swap it for a different model. Hot water cylinders generally have a life expectancy of about 30 years, so it is sensible that older models are regularly checked for water leaks.
If however, you do need to replace your existing hot water tank, or are installing one in a new build project, an unvented hot water cylinder is the preferred choice. Whilst it is a more complicated system than a vented cylinder, it has distinct advantages.
There is no need for a tank of water in the loft, which allows much more freedom of choice when it comes to the location of the cylinder. While the expansion vessel is likely to need replacement before the main cylinder, this is a routine job that any qualified plumber can undertake with no difficulty. Of the two heating systems we have looked at here, the unvented hot water cylinder is quieter and more efficient in terms of water usage than the vented system, so this is the heating system we would recommend.


Our approach is the same for every project: work closely with the client from assessment through construction to prioritize and meet their needs. Our project development phases focus on providing value at every stage:
The Clemson project team is assembled.
The team meets with the client to discuss and clarify the project’s scope, budget and schedule.
The team establishes project reporting procedures and decision-making processes.
When necessary, the team identifies and selects sub-consultants. All sub-consultants utilize Clemson CAD standards, design standards and software.
The team reviews relevant reports, studies and plans such as previous master plans, renovations, mechanical and electrical system and maintenance upgrades, building plans and documents, historical records and client standards and guidelines.
The team then creates a detailed work plan.
The team assesses the clients’ needs, i.e., identifies and documents operational and strategic objectives.
Systems schematics and outline specifications are prepared.
Schematic estimates of probable construction costs based on identified scope are prepared.
A schematic report, outline specifications and engineer’s estimates of probable construction costs are created based on client priorities and budget.
Design Development Phase
Design development floor plans and system schematics to identify equipment locations, utility distribution routing, systems zoning and project phasing are prepared.
The first draft of technical specifications for systems materials and installation requirements are prepared.
Design development estimates of probable construction costs are developed.
Previous needs assessments are reviewed, schematic phase needs are confirmed and client design concerns are addressed.
The team participates in the design development review meeting to review value engineering options, assess systems design, finalize implementation and packaging of contract documents, and refine the project schedule. Design development plans and technical specifications are prepared for review and approval by the client.
Contract documents are prepared for competitive bidding based on approved design development documents.
If necessary, separate bid packages are prepared accordingly to accommodate project scheduling.
Estimates of probable construction costs are prepared based on refinement of project scope and adjustment to contingencies.
Team members attend pre-bid conferences and walk-throughs with contractors/suppliers.
Addenda required for clarifications to the bidding documents are submitted.
The team reviews bids and makes recommendations to the client regarding award of contracts.
Post Design and Construction Services
Respond to contractor’s request for information
Review construction shop drawings and submittals
Perform field inspections
Perform post occupancy evaluations
Assist the client in the formulation of lessons learned
Provide occupancy planning including development of move schedules, cost estimates, inventory lists
Provide telecommunication and computer coordination
The team reviews schedule of values and the contractor’s installation schedule.
Project managers attend scheduled project meetings and prepare meeting minutes.
Team members conduct periodic pre-approved site visits to review work progress and progress payment applications, and verify installation conformance to contract documents.
On-site systems start-up training sessions are scheduled with contractors, suppliers and owner representatives.
The team conducts final site observation inspection and completion of documentation.
Clemson recommends that we be retained to provide commissioning for your mechanical and electrical building systems in order to confirm that these systems are installed and performing to the standards for which they were designed.
The commissioning process involves ongoing interaction with the client and the installing contractors during the construction phase of a project. The process involves installation verification, operational performance testing, functional performance testing, owner training and preparation of a final commissioning report, i.e., documentation compiled during the commissioning process.
In the end, Clemson strives to deliver designs that:
• Meet the client’s goals and budget requirements
• Are properly sized and designed to operate efficiently
• Are fully integrated with all disciplines


Second Sindh Research and Technology Showcase 2023 organized by Sindh Higher Education Commission in partnership with NED University of Engineering and Technology Karachi, highlights indigenously developed technologies/products/services from the Universities and Higher Education Institutes of Sindh Province to the relevant industries, government bodies, R&D organizations etc., for the promotion of research and commercialization culture to create significant impact on the Pakistani society.
The project exhibited at 2nd Second Sindh Research and Technology Showcase comprises the development of reinforced plastic composite construction blocks .The production of plastic waste negatively impacts our ecosystem and contributes to air pollution. These high production rates prompted us to research and investigate the possibility of using plastic waste. Plastic brick, also known as eco-bricks or bottle bricks, are a relatively new invention that has gained popularity in recent years as a solution to plastic waste. Traditionally, bricks are made of dried clay, but recently much research has focused on using waste as an alternative material for traditional bricks. In this research project, thermoplastics waste such as high-density polyethylene (HDPE) and polypropylene (PP) are used to manufacture building blocks through a recycling process. They are preferred over other materials because of their light weight, low cost, low density, superior strength, durability, ability to be easily formed, excellent impact resistance, and mechanical properties. A comparison is made between plastic brick walls and conventional brick walls according to compressive strength and fire resistance tests. The exhibition highlights the immense benefits of polymer bricks, ranging from their reduced environmental impact and energy efficiency to their enhanced durability and design flexibility. Incorporated by Bigger Bricks, a temporary rehabilitation center built of ABS bricks was also shown for better exposition.
The event features a range of exhibits that demonstrate the applications and advantages of polymer bricks in various construction projects. From residential buildings to commercial structures, visitors will witness the seamless integration of polymer bricks in architectural designs, showcasing their adaptability to different styles and construction techniques.


Work Begins on Felixstowe Skateparkadmin | May 27, 2009
After years of fundraising and hard work by many people, the building work has began on Felixstowe Skatepark. The area where the skatepark is to be built on Orwell Green has been fenced off near Morrisons supermarket and Christ Church. Lots of ground work has been happening on the site including the removal of large amounts of top soil for the £180,000 skatepark’s sunken design. The contract was awarded by Suffolk Coastal District Council to Bendcrete Ltd to build the skatepark, who also built Woodbridge skatepark last year.

When faced with roof damage from storms, hail, rain, or wind, many Georgia homeowners wonder if they should simply have their roof fixed or if they should replace their roof and get a total re-roof.
There are several things you need to consider which might affect the decision to repair or replace your roof. You must remember that no two roofs are alike. If you have damage to 30 percent or more of you roof, or there is a lot of moisture damage to the roofing layer or the wood decking, replacing the entire roof may be necessary.
If your roof was damaged by a tornado, hail, or a hurricane, then you should probably replace the entire roof. Damage that cannot be seen often occurs so replacement is the best solution. Better safe than sorry.
Pre-existing conditions can lead to a full roof replacement such as inferior material, bad design, rain during installation leading to mold, and poor installation practices.
Two indications of major roof repair are if the walls and ceilings in your home have moisture marks and/or the paint on your walls and ceilings are flaking or peeling.
Long, hot sunny days, wind, tree branches, and ice can cause damaged or missing shingles. In most cases the repairs are fairly inexpensive and easy to accomplish. However, there is always the chance of more serious conditions.
That is the reason it is always important to consult with a professional roofing contractor who can help you determine if there is a major problem.
Asphalt shingled roofs should last between 15-20 years if the materials used in the initial installation were of good quality. If your roof is over 12 years old and experiencing roof leak problems, you should consider replacement.
If you have more than 3 layers on your roof and are having problems then it’s probably time to replace it.
When pressed for an answer, most reputable roofing contractors will give you an honest answer as to whether to repair or replace. Always get three quotes and opinions with dealing with any contractor. Always check with the Better Business Bureau on any contractor you intend to use to make repairs. source
The Next Step…
The very next thing you should do is contact a reputable local Roofing contractor near you and get them to perform a free roof evaluation and roof repair estimate.


Is Trackless Gate good?
Trackless gates can offer several advantages and are considered a convenient and space-saving option for certain applications. Here are some potential benefits of trackless gates:
Space-saving design: Trackless gates do not require a bottom track or rail system, allowing for more efficient use of space. This can be particularly advantageous in areas where the installation of a traditional sliding gate with tracks may not be feasible.
Flexibility in installation: Trackless gates can be installed in various locations, including areas with uneven ground or limited space. They can be customized to fit different architectural styles and site conditions.
Ease of use: These gates often come with motorized or automated systems, making them easy to open and close with the push of a button or through remote control. This convenience can be especially useful for properties where frequent access is required.
Reduced maintenance: Trackless gates typically have fewer mechanical components compared to traditional sliding gates with tracks. This can result in lower maintenance requirements and potentially reduced long-term costs.

PAPAR: The Federal Unity Government, led by Prime Minister Datuk Seri Anwar Ibrahim, has approved the recommendation of the Sabah and Sarawak governments – the devolution of powers the Technical Committee of the Public Works Department and the Irrigation and Drainage Department to implement federal development projects worth less than RM50 million.
Minister in the Prime Minister’s Department (Sabah, Sarawak Affairs, and Special Duties), Datuk Armizan Mohd Ali, said the devolution is expected to help expedite the implementation of various planned projects, thereby boosting economic development in both states.
He said this means that federal projects valued at less than RM50 million that were previously implemented by federal agencies are now directly implemented by the Public Works Department and the Irrigation and Drainage Department.
Armizan told reporters this after officiating the Bicara Merdeka Programme in conjunction with National Day 2023 at the SM Agama Negeri Toh Puan Hajjah Rahmah in Kinarut, near here today.
He said empowerment was also given to district offices to implement projects at the grassroots level.
However, he said the problem that is often raised is the lack of technical officers to supervise and monitor the implementation of federal projects at the district level.
In this regard, he said the federal government agreed to place three technical officers on a contract basis, namely one engineer and two assistant engineers, in each of the 38 districts in Sabah.
Armizan said with the appointment of the technical officers, it will help speed up the implementation of federal development projects for the good of the people.
Commenting on the Bicara Merdeka programme, he said it was the best platform for the people to understand the significance of independence day and the sacrifices of past leaders who worked tirelessly to develop this country.
Armizan said it also provides an opportunity to deepen the knowledge of the Madani’s aspirations, which are aimed at enhancing the economy and the well-being of the people.

Every type of roof has its strengths but no roof, no matter how well built is completely immune from the relentless assaults from wind, sun, and rain. Sooner or later a roof will need some repair work and while we always prefer to avoid repairs through our preventative maintenance programs it's good to know we are there on call if things need a little fixing.
Leaks can be down to a number of causes depending on the type of roofing but our first steps usually involve examining the flashing. Drains and gutter issues are another source of trouble since any water that's not encouraged to flow away runs the risk of ponding. If there's standing water then you have a secondary problem in the making because that water exacerbates the affect of UV damage so it's essential to call us as soon as you notice water isn't running away as it should.
Blistering, Cracks, Punctures
Blistering is a big problem for built up roofing and is usually the fault of the asphalt layers not having been heated to the right temperature when they were applied in the first place. It's not a problem with our professionally installed roofs but we often get called in to fix other people's work where significant blisters and cracks are opening in the asphalt. Some blisters aren't a problem but there is always the risk of the blisters bursting and starting a process of water ingress. Punctures aren't something you associate with roofing but they are a real problem for membrane roofs and often happen due to improper installation or maintenance workers accidentally being a little heavy handed or careless. Once the membrane is punctured there is a risk of leaks and erosion so we will find the puncture and fix it.
Shingle and Slate Replacement
Broken shingles or tiles should be replaced as soon as possible before the elements get a chance to do their thing and work on the surrounding tiles. It's often not a big job but for our roofing professionals it is also an opportunity to check that there isn't any further damage beyond the broken tiles you can see. We also check for any underlying issues with the frame or underlay that may have led to the tile problem in the first place.
Preventative Maintenance and Inspections
We know from long experience that the very best way to repair a roof is to ensure it never gets the point where it needs repairs at all and that means preventative maintenance. We are happy to inspect your roof and suggest everything that needs to be done and the steps that can be taken to reduce repair bills in the future. We provide roofing inspections for property buyers before they buy, for insurance estimates, and on a regular basis for commercial and residential maintenance. Why worry about the roof over your head when you can make the job of full time roofing professionals to take care of your property?


There are a lot of factors that influence the use of roof replacement Frederick. But there are some salient features that cannot be simply ignored that ensure a good work at the right budget too. The prime concern of any roofing contractor is timely completion of any given work and within the estimated budget. It does not help toward the reputation and as well as the work quality to have cost over runs as well as not finish within the time set forth.
Discussed in brief are some of the more prominent points that need to be heeded at the time of any build.
Sticking to the cost estimate with roof replacement Frederick
The cost is important with any project and a contractor that realizes the importance of the cost factor would try and keep the work within cost by all means. A consistent habit of cost over runs does not reflect kindly on the ability of any worker and with time would soon get to be a trait of a particular contractor.
People are always cost conscious and with some work the cost of executing a work would be the single most important factor. There are of course workers that would quote a low rate for work only to land a job with very little intention of sticking to the given estimate. This is a very wrong practice and can bring about a bad reputation in the long run. In a field that relies on reputation more than anything else this could well be suicidal.
The need to be in complete control at all times during a project
Keeping costs under control is just a single factor in any work and there are other factors that need to be kept in check as well. Of prime importance to any work is the quality of materials used. Often in a bid to keep costs down, the contractor resorts to using very substandard work materials. This can really hurt the reputation of a contractor in the long run. The consequence of using poor work material is that the work executed would not last long and more patch work would need to be done soon after the completion of a work.
Most people would not take kindly to having to spend an extra sum in rectifying a fault that occurs due to poor quality work material. As the first work would be in itself costing a packet, to having to rectify faults would not be taken to every kindly. This would affect the reputation and standing of any roofing contractor in the long run.
The need for competent personnel
Few people realize the importance of the workers in any work and it would be rather an understatement to say that they are important as well. A good worker takes pride in his work and would produce work that is with quality as well as use good quality work material at all times. Rectification and repairs are minimal when proper skills are applied to any work.

The most common interior concrete sealers include the film-forming ones you apply to the surface of the concrete. There are several types of sealers, though, to consider. Polyurethanes have a high-build protective film on the concrete surface and are best on high-traffic flooring, providing good resistance to staining and scuffs.
Acrylics form a thin protective coating on the surface of the concrete and are available in water-based and solvent formulations. If you require concrete sealing services, contact DPA!

Last update: May 3, 2013
Glacier Point Road: Opened on May 3.
Tioga Road: Tentative opening date of May 11. Bicycles will not be allowed on the Tioga Road prior to the road opening because of rock debris and snow plow operations, which make the roadway unsafe for bicyclists and pedestrians.
Dates listed above are contingent upon safety of the park crews and on conditions. Any spring storms would result in road crews being diverted to keeping other roads open and may delay opening of the Tioga and/or Glacier Point Roads.

Road markings need to be robust and durable but this can make their removal difficult. With hydroblasting, highway lines - whether thermoplastic or painted - are removed quickly and efficiently, without damaging the surface or substructure.
For cutting concrete, hydroblasting is an efficient alternative to traditional methods such as jackhammers and large-wheel saws. The technology allows concrete of almost any thickness to be cut through cleanly and quickly, with no damage to steel reinforcements and minimal dust.
The traditional method of anti-fouling - using the sandblast technique - is increasingly being replaced by hydroblasting as the preferred solution and with complete control, water pressure can be adjusted to suit precisely the number of coating layers that require removal.
