Without regulation, the balancing tank is a simple water tank that will not perform its function properly and will force you to manually ensure that the water level is maintained. The installation of pool water levellers avoids , among other things, your pump from burning out or your water consumption from exploding Animated Video created using Animaker - https://www.animaker.com Team 5 animatio , and stores it before the water is returned to the pool via a system of recirculating pumps, filters and other water Water feeds the one tank only via a 100mm storm water pipe and the two tanks were originally interconnected for balancing via a 32mm poly pipe on ball valves. This will never keep up with the 100mm inlet and if we get a massive shower the first tank will overflow before the second tank is full

Standpipe: A water tank that is a combination of ground storage tank and water tower water. It is slightly different from an elevated water tower in that the standpipe allows water storage from the ground level to the top of the tank. The bottom storage area is called supporting storage, and the upper part which would be at the similar height of an elevated water tower is called useful storage This balance valve allows the plumbing contractor to have the system balanced by throttling the valve. The ports provided allows reading out the pressure drop and referring to programs or tools to determine the flow rate during and after adjusting the valve. A memory stop assures the valve will be returned to the correct setting if the valve is used for its 100% shutoff capability during service The law of water balance states that the inflows to any water system or area is equal to its outflows plus change in storage during a time interval. In hydrology, a water balance equation can be used to describe the flow of water in and out of a system.A system can be one of several hydrological or water domains, such as a column of soil, a drainage basin, an irrigation area or a city
Introduction to processes and the general material balance. A short example on a tank with inlet and outlet flow. Made by faculty at the University of Color.. Keywords: Optimization; Reliability; Demand balancing tanks; Water distribution networks. 1. Introduction Water distribution networks (WDN) are vital part of urban infrastructure and require high investment, operation and maintenance costs. Their design is a complicated task due to strong interconnections between the network components and hydraulic parameters such as nodal pressures and. A water balance is a set of very simple calculations to balance all the inputs affecting a wastewater system and all the outputs returning the hydraulic load (the water) to the hydrologic cycle. Perhaps the easiest way to visualise what is meant by water balance is to think of our wastewater system as a bucket as shown in Figure 1

Storage Capacity of Distribution Reservoirs. The total storage capacity of a distribution reservoir is the summation of: Balancing Storage: The quantity of water required to be stored in the reservoir for equalising or balancing fluctuating demand against constant supply is known as the balancing storage (or equalising or operating storage). The balance storage can be worked. Pool Water balancing is not such a complicated exercise. It is simply the relationship between different chemical measurements in your pool water. Your pool water is constantly changing, year round. Everything that comes into your pool will affect your pool water balance - in short, anything that comes in contact with your pool water. You will probably not change the water in your pool for.
Swimming Pool Balance Tank Cleaning Engineers. Along with filtration and chemical dosing, balance tank cleaning is key to keeping the pool water well balanced and safe. Bathers bring substances into pools, which adhere to the water particles causing bio-films to form on the water's surface. Bacteria can become a problem in such circumstances 6,422. Make up your mind. Either use mass flows, mass balance, and energy balance, or volume flow, volume balance, and temperature balance. Since you are dealing with water, it is easy either way. Use the Isobaric volumetric heat capacity (or ) to convert between the two representations.

If your pH is too high or too low, you will need to use pH minus or pH raiser to fix that. I've only ever had to use pH minus, and I probably only have to do that twice a season. If the pH isn't right, the chlorine cannot be used properly! So make sure to use the chemicals when you need them, and follow the instructions on the bottle. Step 3. Add chlorine.. All water supply systems use a combination of pipes (of different dimensions and materials), valves and outlets to deliver water to building users. Some water supply systems also use storage tanks and pumps. Designing a water supply system involves getting all of these elements right so that clean water is delivered to the user at the appropriate rate and temperature Balancing your tank to the fish who live there is key to their health and safety. Check the water you have before you decide on the fish you are going to get. Remember to let it stand for a minimum of 24 hours. Then test the water. That gives a true picture of the pH. This is also important if you are moving your fish. The new tank must have the same pH. If you are introducing new fish into.

Massive shortages have been reported for framing lumber this year, according to the National Association of Home Builders (NAHB). Lumber costs are steadily on the rise and it doesn’t look like there will be relief any time soon. Home builders are eager for solutions that can reduce lumber costs without sacrificing quality or structural integrity. One popular solution is value frame engineering at DPIS.
How it Works
Frame engineering takes the smart approach by precisely and meticulously pinpointing strut locations onto beams. This minimizes the number of struts needed while still providing rock-solid structural integrity to the homes. The smaller beam sizes required in this process further reduces the amount of wood required. The precise nature of this technique also allows for the widest range of lumber choices which results in greater efficiencies.
What to Look for in a Frame Engineering Plan
A proper frame engineering process will provide ceiling joist layout, beam locations, rafter layout, and purlin in addition to strut locations. An integrated floor system design is a good idea for high quality homes or homes with more complicated floor loading due to design parameters.
Finding the right plan means finding the most detail. In general, the most extensive plans are more accurate to your specific needs and require a highly knowledgeable engineer to complete.
A good plan should show layout, size, spacing and allowable span for all these areas. And it should integrate each area with a comprehensive, big-picture view as well as the scrutinized details. Our method at DPIS incorporates both of these important factors. Give us a call and discover how frame engineering with DPIS can start saving you money this quarter.

No, it does not matter if you don’t have an electricity grid connected to your property.
We will work with you to understand your loads and uses of these loads, then design a system to suit your energy needs.
This type of system is typically known as OFF GRID.
Unfortunately, one size does not fit all solutions. We need to consider a number of factors when designing a system suitable to your needs.
For example, best panel positioning, orientation, available roof space, available control system space, energy needs and use are the main drive factors for installing solar.
There are also a number of situations when battery storage is a good solution when coupled with solar energy.
This will entirely depend on the demand for power from the system and the rate at which energy is required.
Each system is designed to be tailored to the customer’s needs.
Solar modules have been tested in controlled environments as well as in the field, with results showing module lifetimes in excess of 25 years.
Modules typically have 25-year performance warranties and 10-year workmanship warranties.
Solar panels are approximately 1 metre wide and 1.7 metres high. Most systems are designed and installed in rows. Traditionally one would normally leave a minimum of 2 metres between rows or more if mounted on a frame to avoid shading by the adjacent panels.
The general rule of thumb is to allow 300 square metres per 10,000w.
Commercial solar systems which are purchased and installed under the current rebates and tax incentives usually pay for themselves in approximately 4-6 years.
The exact return on investment will depend on electrical usage, the current and future cost of power, and the overall cost of the solar system.
Typically speaking, larger systems will be better suited to ground mounts. For example, a 50kW system in size and greater is our recommendation.
Power is normally supplied directly to the grid at an agreed tariff. Ideally, you would need to secure a site for 20 plus years for the system viability and return on investment.
Buildings which are best suited to commercial solar systems have flat roofs or an orientation to the North.
Most roof types are suitable for solar panels, including tile, tin, kliplok and concrete.
Large roof spaces cater well for larger solar systems.

World is researching to get more energy from sustainable energy sources as fossil fuels causing lot of pollution. In a step forward, Dutch engineers claimed their under test solar road is generated more power than their initial expectations. Dutch company “SolaRoad” is experimenting on a road paved with solar panels to generate sustainable energy for human needs. In 2014 they laid a 70-metre test bike path with solar panels near the Dutch town of Krommenie on the outskirts of Amsterdam.
Over the 3,000kwh energy is generated in the first six months since it was installed from the panels beneath the bike path. This power is enough to provide a single-person household with electricity for a year. This is an extraordinary achievement as we expect more than the 70kwh per square metre per year,” says Sten de Wit, spokesman for SolaRoad.
SolaRoad uses cheap mass-produced solar panels and sandwich them between layers of glass, silicon rubber and concrete. The current version of the panels can withstand a fire brigade truck of 12 tonnes without any damage,” said Arian de Bondt, a director at Ooms Civiel, one of consortium of companies working together on this pilot project.
They are researching on this for past five years to develop a road that can withstand big trucks and large vehicles. If they succeed then we no need to worry about energy anymore.


Four more miles of US 68 will open to four-lane traffic in Trigg County on Friday.
The section of US 68 runs from the west connection with US 68-Business at Cadiz extending eastward to the eastern connection with US 68-Business, according to a news release from the Kentucky Transportation Cabinet.
A state contractor anticipates making the switch to four-lane traffic sometime around noon on Friday, weather permitting.
Motorists should be alert for construction personnel along the roadway during the day Friday moving traffic control equipment to make the shift possible.
Drivers should use appropriate caution and be alert for changes in traffic flow that will be created at intersections along US 68 around Cadiz.
After the traffic shift on Friday, motorists should be aware that it will continue to be an active work zone. Lane restrictions will be required along this section of US 68 to complete ongoing electrical work, as well as landscaping, guardrail work, and other finish work along the project area.

Roof Gardens have a deeper growing medium than Extensive Green or Brown Roofs because trees, shrubs, turf, and hard landscaping can be incorporated into the design. To create a green roof, you first install a layer of waterproof membrane and provide adequate drainage. Go green with a roof garden from Bauder. Green roofs have been proven to help reduce heat islands. These are not the same distinctions we discussed in our introductory post on green roofs, relating to the type of planting. by alan burchell & rubyana lyon green roof mar 3 2017. All three types of roofs require specific layers of roofing materials not found on regular roofs. Article by Cristina Ferrara – We explore 10 of the best green roof designs in the world, looking at what makes them so special and how they impact their environment. In order to reduce differences based on roof types, we will only deal with the extensive roof type. Types of Green Roofs. These areas are more like small parks rather than roofs. Succulents, particularly colourful sedums, dominate shallow substrate green roofs across temperate Europe and North America. Each green roof is unique, as their designs and performance vary by region, climate, and building type and use. The main factors which influence the shape of roofs are the climate and the materials available for roof structure and the outer covering. Intensive green roofs require the deepest soil and have the greatest impact on the structural design, but they also accommodate all types of plantings including large shrubs and trees. Green roof presentation 1. Green roofs are covered with plants and can improve air quality, reduce water runoff and insulate homes to reduce urban heat islands. Each green roof brings back a piece of nature and on some buildings a recreational space can be created for people to enjoy. Their estimated lifespan is 40 years. This is better for the climate and for health. Green roofs are versatile and can include a vast array of different plants or designs. There are three main categories of green roofs: Extensive – This is the simplest kind of green roof, involving small plants and greenery that … It can put oxygen back in the air, provide thermal insulation to your house, absorb rainwater, and even allow you to grow plants. Intensive – These roof types can support trees, shrubs, and even benches. Thanks to its simplicity, it costs less to build than an intensive green roof. Green roofs come in many different forms and types, including extensive, intensive and biodiverse or brown roofs. A green roof offers many benefits in terms of sustainability, the environment and perceived value. A green roof absorbs rain water by the water buffering in the plants, substrate and drainage layer. Comparison of the various green roofs An extensive green roof is characterised by its low weight, a thin layer of growing medium (green substrate), a mix of plants adapted to conditions on the roof, minimum maintenance and low installation costs. Seed mixtures can be bought specifically for green roofs. They require complex structural support and irrigation. Got a stunning green roof project of your own? Provides a rainwater buffer. Roof terminology is also not rigidly defined. Link to this table. General characteristics of extensive and intensive green roofs (adapted from Green Roofs for Healthy Cities and the Cardinal Group, 2006). A green roof is one that is covered – either partially or completely – with vegetation. However, they need extra structural support, a vapor barrier, thermal insulation, waterproofing, drainage, water filtration, soil, compost and plants. Noise Reduction. Types of green roofs 7 Intensive ExtensiveSemi-intensive 8. The environmental benefits provided by green roofs derive from their functioning as ecosystems. Green roofs are usually covered with an artificial soil or growing medium to minimise roof loads but earth-sheltered homes often use heavier natural soil as a continuation of the indigenous site conditions. GREEN ROOFING TECHNOLOGY M. ARAVIND MBBS I YEAR DSMCH, PERAMBALUR 2. Intensive green roof • Depth 10 inches and more • Supports trees and shrubs • Initial investment is high • Heavier than both the types • Requires more maintenance 8 9. Intensive systems allow the designer to create a park-like setting so they are the best option for roof … 9. WHAT ARE GREEN ROOFS? A Bauder green roof combines the finished planting scheme and all its supportive components with a high quality and secure waterproofing system to give you the best results every time. Roof shapes differ greatly from region to region. The other type of green roofs is called extensive green roofs. This paper will give basic information on green roofs, their advantages, construction elements, as well as different substrate types and features. Submit your projects before February 14th to secure a special Early Entry Discount.. Green roofs are making a comeback. Green roofs can be seen as flat or very low-slope roofs, partially or completely covered with vegetation; they are mostly of two great types 1) modular, that is, built with pre-vegetated plastic trays 2) or site-built with a layer of soil and vegetation.. What green roofs are not. The plants used in this type of green roof are mostly sedum varieties. The basic anatomy of a green roof consists of vegetation, growing medium, filter membrane, drainage layer, waterproof/root repellant layer, roofing membrane support for plantings above, thermal insulation, vapor control layer, and structural roof support. DIfferent Types of Green Roofs 0 July 30, 2012 1:03 pm July 30, 2012 A green roof allows vegetation to grow in a growing medium and usually includes the following elements: waterproof membrane, a root repellent system, a drainage system, a filtering layer, a growing medium and of course plants. A green roof or living roof is a roof of a building that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane.It may also include additional layers such as a root barrier and drainage and irrigation systems. Green roof: types, construction & pros and cons. A green roof, or rooftop garden, is a vegetative layer grown on a rooftop. This style of roof requires regular maintenance, including weeding and pruning. This page provides a brief overview of the role of green roofs in mitigating the heat island effect, including green roof types, other environmental and social benefits, and cost-benefit considerations. Extensive green roofs have a shallow growing medium and generally use plant communities designed to tolerate the intense sun, wind and drought conditions of a roof … These terms refer to the degree of maintenance the roofs require, and the level of vegetation that can be utilised. They are mainly developed for aesthetic purposes, but also have various advantages to the environment. Extensive Green Roof. Green roofs are vegetated layers that sit on top of waterproofed roof surfaces of a building. These types of green roofs are covered by lighter vegetation and are easier to maintain than the intensive green roofs. Studies on a large number of sites are necessary to understand the importance of environmental variables, especially how the type of vegetation affects the green roof … Extensive Green Roofs. A green roof has many advantages and different green roof systems can be distinguished. The vegetation converts CO2 into oxygen and filters particulate matter from the air. Usages vary slightly from region to region, or from one builder or architect to another. In an inexorably urbanizing world, green roofs could be an interesting tool to conciliate the greening of cities with ecological services. The roof structure will require extra loading capability to withstand the weight of the roof garden and support an irrigation system for maintenance, if required. 3 Different Green Roof Types . As well as protecting buildings and adding character to the urban environment, green roofs can help to manage rainfall and create diverse new habitats for plants, wildlife, and people. The types of plants that you will have will depend on the type of green roof you are installing. Green roofs are becoming very popular, especially with house owners who have an eye for nature and also with companies and towns that are paying more and more attention to ecological management. In urban areas in particular, green roofs can significantly improve air quality. Three types of green roofs exist: extensive, semi-intensive, and intensive green roofs. Below we explain the benefits one by one. While there are an infinite number of potential designs for green roofs, there are two principal types:intensive and extensive.There is another type of green roof, known as ‘semi-intensive’, which lies somewhere between the intensive and extensive varieties.The difference between these types comes down to the depth of the material which is placed on the roof. Standards relating to flat roof and green roof construction distinguish between different types of green roof. For extensive green roofs, it’s good to use moss, sedum, herbs and grasses. Semi-intensive: Semi-intensive roofs can … For semi-intensive green roofs, consider grasses, shrubs, small trees, woody plants and herbs. green layers which can differ in different types of green roofs. 8. There are three types of green roofs. Plant finishes; depths and types of substrates; and drainage boards are all carefully considered in each green roof system to allow the roofs to flourish. Living roofs Vegetated roofs Eco roofs Roof gardens DEFINITION: A green roof is a planted roof top Container gardens on roofs are not generally considered to be true green roofs. Types of GREEN roof construction and plants used in them. Each type of green roof brings different benefits, so it is well worth learning more about each system on offer. Green roofs are part of climate-proof construction. Green roofs have excellent noise attenuation, especially for low frequency sounds. The following table summarizes characteristics of the different types of green roofs. An extensive green roof has the benefits of an intensive one, without the heavy landscape and garden appeal. Green roof systems are generally classified as extensive, semi-intensive or intensive. Types of green roof plants Low-growing succulents. Types of Green Roofs. Semi-intensive green roofs represent a roof design intermediary between extensive and intensive roof. What are Green Roofs. Although green roofs represent a distinct type of urban habitat, they have been treated largely as an engineering or horticultural challenge, rather than as ecological systems. Green roofs mainly consist of a vegetation layer consisting of trees, plants, and other shrubs, a substrate layer where water is retained and in which the vegetation is secured, and a drainage layer which helps to evacuate excess water. Enter it in the 8th Annual A+Awards for a shot at international publication and global recognition. The systems differ in many ways. Green roofs. What's more, people are happier in a green environment than in grey surroundings. Green roofs are capable of reducing electromagnetic radiation penetration by 99.4% (Herman 2003). A truly unorthodox type of roof, the green or living roof nevertheless holds much promise. Their roofs are essentially green roofs and usually deep (intensive) roofs that need considerably more structural support than the more shallow extensive type. Green roofs of this type can include bushes and small trees, gardens, and more.


Alpharetta to spend $10M extending Big Creek Greenway
The Alpharetta City Council has approved spending more than $10.5 million on a 1.77-mile extension of the Big Creek Greenway.
The Greenway will be extended from Marconi Drive to Union Hill Park, with about a half-mile of the extension to be an elevated concrete trail, according to a staff report to the council.
The council awarded a construction contract valued at roughly $10.1 million to Integrated Construction and Nobility Inc. (ICAN); approved Atkins North America Inc.’s $372,572 proposal to handle construction management, engineering, and inspection services; and allocated $100,000 for utility relocations.
CAN anticipates being able to mobilize and begin construction by the end of January 2020,” with an anticipated completion of the project “no more than 480 days from the notice to proceed,” staff said.
The Alpharetta portion of the Big Creek Greenway is a concrete trail and linear park that runs eight miles from Mansell Road on the south to Windward Parkway at Marconi on the north. Information: https://www.alpharetta.ga.us/government/departments/recreation-parks/facilities/big-creek-greenway


….Announces alternate routes
The federal government, in collaboration with the Lagos state government said emergency repair work on the Eko Bridge from Costain to Alaka will commence with partial closure from June 4 to August 13, 2021.
Olukayode Popoola, federal controller of works in Lagos and Fredric Oladeinde, Lagos state commissioner for transportation, while announcing this in separate statements, explained that, the repairs were necessary to complete the rehabilitation at the opposite side of the bridge earlier embarked upon by the Federal Government.
Lagos state government said it had prepared alternative routes for motorists during the period of repairs, while the federal controller of works appealed to the public to shun rumours that the bridge would be closed on Friday, May 28. He promised that, the construction would be fast-tracked to minimise discomfort for road users.
According to the statement, which read in part, “The Federal Government shall embark on the rehabilitation of Eko bridge and to facilitate early completion. The bridge shall be closed from midnight of Friday 4th of June until Friday 13th of August. “The motoring public are advised to disregard the rumour going on that Eko bridge shall be closed from Friday 28th of May. The Federal Government regrets the inconveniences this may cause the public.”
Meanwhile, Lagos commissioner, Oladeinde, said alternative routes had been made available for motorists during the period of repairs. He said, “Traffic from Apongbon to Alaka, stadium, inner Surulere or Ikorodu road will be diverted to Eko Bridge to access Costain roundabout to Iponri, through Alaka and Funsho Williams Avenue.
Similarly, motorists from Eko bridge will have to navigate their desired destinations through Costain roundabout to Abebe Village (by Nigerian Breweries Plc) through Eric Moore to Bode Thomas to Adeniran Ogunsanya, to access Shitta Roundabout by Stadium under the bridge to Funsho Williams Avenue to Dorman-Long Bridge and Fadeyi-Ikorodu road.
Motorists can gain access to Apongbon through CMS Outer Marina Road to connect Ebute Metta Ikorodu road to access their destinations. Apongbon through CMS to Outer Marina to Adeniji Adele, Third Mainland Bridge, Adekunle to Herbert Macaulay Way, Jibowu and Ikorodu road will also be available.” He added that traffic directions and road signals would be made available to minimize inconveniences throughout the construction period.

CLICK HERE to see what ENERGY.GOV has to say about sealed crawl spaces?
Why sealed crawl spaces or crawl space encapsulation?
Many building professionals in Raleigh, Durham and Chapel Hill, now recognize that building an unventilated crawl space (or closing vents after the crawlspace dries out following construction) is the best option in homes using proper moisture control and exterior drainage techniques. Insulating the foundation walls, installing a sealed vapor barrier, adding a crawl space dehumidifier, installing a sump pump, and if necessary a french drain.
If you have or will have an unventilated crawl space, the best approach is to seal and insulate the foundation walls rather than the floor between the crawlspace and the house. This strategy has the advantage of keeping piping and ductwork within the conditioned volume of the house so these building components don't require insulation for energy efficiency or protection against freezing. It’s best to build and maintain an airtight, insulated access door in the perimeter wall.
Sealed crawl spaces perform better in terms of safety and health (pest control), comfort (warm floors, uniform temperatures), durability (moisture) and energy consumption than passively vented crawl spaces. Crawl spaces should be dry so that they are less likely to have pests, termites and mold. A dry crawl space is therefore safer and healthier than a wet crawl space. Ground cover prevents evaporation of ground moisture into the crawl space.
However, vented crawl spaces experience serious moisture and mold problems that cost builders and the homeowner significant resources to repair. Also, wintertime ventilation makes crawl spaces colder and increases the heat loss from the home – venting crawl spaces wastes energy, and can lead to freezing pipes and uncomfortable floors.
In short, crawlspace vents should be sealed, crawlspace walls insulated, rim joists and spaces where air may leak should be sealed, and the ground should have a continuous sealed cover such as taped polyethylene.


Brent Council is proposing multiple road closures across the borough, which will have a severe and detrimental effect on many residents and visitors. Brent is implementing these measures immediately using 'Experimental Traffic Orders' to avoid consulting with the community beforehand.
Initial plans were leaked, leading to significant local opposition. As a result, Brent now intends yo implement the road closures in stages, with Tiverton Road bridge to be closed as a first step, before putting in place the others.
After the closure of Tiverton Road, Brent plans for the following roads to be blocked, some in more than one place:
1. Chevening Road;
2. Hanover Road;
3. Kingswood Avenue;
4. Mount Pleasant Road;
5. The Avenue.
These closures will force even more traffic onto Chamberlayne Road and Salusbury Road, lengthening journey times and significantly increasing congestion and pollution. Both these roads already suffer from delays, long tailbacks and significant pollution and both have large primary schools roadside. The impact will be especially harmful for those residing, attending school or struggling to make a living in these roads.
Click below to see how these schemes could affect you.
These closures are underway already.
We are awaiting more information on this area.

Intermodal simulation with the Road Traffic Simulator
The SimWalk Road Traffic Simulator (RTS) allows to model all areas where car traffic and pedestrian interaction must be analyzed. Conduct capacity analyses at intersections, ramps, pavements, crossings, intersection corners, roundabouts, metro and station entrances - all in the same SimWalk model. Discover
the full potential of an intermodal simulation to improve transport infrastructure
The SimWalk ‘Road Traffic Simulator’ (RTS) is a microscopic continuous-time traffic flow model, based on the principles of the intelligent driver model (IDM). The IDM is a car following model; the decision of any driver to accelerate or to brake depends on her own speed.
The RTS module is an add-on to the SimWalk Pedestrian Simulator, based on an independent traffic engine communicating with the User Interface. It is destined for small- to medium-sized traffic networks, such as intersections, small urban areas or station environments.
Simwalk track nodes are used to define start and destination points as well as road traffic signs (e.g. speed limit, yield, stop or lights). Vehicles are used to determine the color and dimension (e.g. body, axles and bumpers) and type of cars (e.g. car, van, bus, truck...).

Due to its nature reed is suitable for developing any traditional roof forms. It is capable to follow every curves and corners of the roof perfectly. Reed is a natural material it does not do any harm to the environment. Due to its excellent heat insulation characteristics it is suitable for roofing buildings made by both traditional and eco-technologies. In summer reed roofing keeps the houses cool while in winter it preserves their heat.


WSP to assess environmental impact of MarramWind
WSP, one of the UK’s leading engineering and environmental professional services consultancies, is to assess the environmental impact of the proposed MarramWind offshore floating windfarm secured as part of the ScotWind leasing process in Scotland on behalf of ScottishPower Renewables and Shell.
Alongside the proposed CampionWind windfarm, MarramWind would be among the world’s first large-scale commercial floating offshore windfarms and could bring enough clean energy to power the equivalent of more than six million UK homes.
WSP will provide key front-end services, including Environmental Impact Assessment, stakeholder engagement and consultation support, advising on onshore works as well as supporting wider consents and licensing requirements.
Richard Eakin, Project Director for MarramWind, said: “We’re really pleased to have WSP on board, bringing its industry expertise and knowledge to help us deliver these exciting projects, which will help transform the offshore wind industry and have the potential to power the equivalent of more than six million homes with clean, green electricity.
“This contract award also highlights the potential supply chain opportunities our ScotWind projects will offer, and we look forward to working with companies across the supply chain to deliver jobs, investment and a clean energy future for us all.”
Ian Cromie, Senior Vice President for Environment and Infrastructure at WSP, said: “It’s fantastic to be supporting ScottishPower and Shell on these innovative clean energy projects. This will be a step-change in the future of large-scale, offshore floating windfarms and the technology and the will to see projects like these come to fruition is accelerating.
“The contract builds on Wood E&I’s extensive track record of supporting offshore wind and other major infrastructure projects from an environmental, engineering and technical perspective in the development phase and through the project lifecycle globally.”
Barry Cowell, Head of Earth and Environment at WSP, said: “As the UK works to develop its offshore wind capacity to deliver our energy transition and achieve net zero carbon emissions by 2050, it will be essential that these initiatives simultaneously protect the habitats and environments in which they are built.
“We’re excited to be working on sector-leading projects like MarramWind and CampionWind, to deliver a clean future for Scottish communities.”

In recent years, the Florida Keys have become increasingly accessible and friendly to bicyclists and pedestrians. The Florida Park Service has already completed more than 70 miles of the Florida Keys Overseas Heritage Trail, which will one day link Key Largo to Key West via a paved multi-use path. In addition, new sidewalks and crosswalks have been constructed by the Florida Department of Transportation, while local governments have also gotten into the act. For example, last year Monroe County completed a 12-mile-long bike lane along County Road 905, in North Key Largo. The county is also building a new bayside bike path in Key Largo to augment the state-owned oceanside path.
Despite this progress, a recent analysis undertaken on behalf of the county shows that there is much work that can be done to make the Keys transportation network safer and more efficient for everybody.

Best sander for concrete floor Buying guide
Finding the best sander for your concrete flooring project is an important part of the process. Consider the following features when selecting the best sander for your project:
1. Power Source: Electric sanders are the most common for concrete flooring projects, but pneumatic and manual sanders are also available.
2. Sanding Head: Select a sander with a large, flat sanding head to ensure that the entire surface of the concrete floor is properly sanded.
3. Dust Collection: Look for a sander with a dust collection system to ensure that the dust generated by the sanding process is contained and not released into the air.
4. Variable Speed: A sander with variable speed settings will allow you to adjust the speed of the sanding process to suit the job at hand.
5. Sanding Discs: Choose a sander that is compatible with different types of sanding discs, such as standard sandpaper or diamond-coated discs, to ensure you have the right tool for the job.
By considering these features, you can select the best sander for your concrete flooring project.


Soft-Actuation Based Dynamic Facade for Building Performance
Our concept is to create a soft-actuation-driven dynamic architectural facade element that enhances building performance. The American Institute of Architects (AIA) has established a goal for 2030: all proposed and built projects must be net-zero. Whether or not that is achievable is not within the scope of this research.
Our system uses a soft, flexible, and robust material as a mechanical pump, creating a negative pressure in a closed-loop heating system. High-performing architectural facades inspired this proposal in locations farther from the equator, which sees relatively higher temperatures during daylight hours and vice versa. A few architectural terms must be addressed to understand this project proposal fully.
- Low-E Coating
- A type of metallic, invisible to human eye coating that is applied onto glazing assembly to reduce infrared light transmission rate significantly. It is often used to allow natural light to enter and block heat.
- Direct light creates a highly uncomfortable indoor environment.
- Internal Heat Gain
- Somewhat related to the purpose of Low-E Coating. Internal Heat Gain refers to the increasing temperature inside a building, usually caused by solar radiation penetrating the glazing assembly. Still, it can also penetrate via opaque surfaces much slower.
- A light measurement unit.
The plan above depicts the two states of our system. Upon exposure to daylight or heat, the soft pump will activate and enlarge, pulling water resources from an off-site location. Then, the water inside the pump structure would be maintained inside and gradually heated up due to solar exposure. To accelerate this process, Low-E coatings are applied to the interior of the assembly chamber, effectively trapping heat. This process will also reduce the building’s internal heat gain. At the same time, the enlarged pump structure will serve as a shading device, reducing glare and creating indirect light.
Once the exterior temperature or lux drops to a certain threshold, the heated water will be released inside a closed-loop heating system via tubes connected to the pumps. The heated water can then be used as hot water for lavatories or as floor heating using a pex-tubing system.
We are currently investigating the affordance of the soft pumping mechanism, especially the volume differences between the two states. Ideally, the greater the difference, the more efficient and cost-effective this system will be. However, other issues regarding the system invites future studies, such as maintenance, material, and thermal-exchange performance.


Marble powder is a waste product formed during the production of marble. A large quantity of powder is generated during the cutting process. The result is that about 25% of the original marble mass is lost in the form of dust.
It is also known as calcium carbonate, a chemical compound with the formula CaCO3. At room temperature, it is a white slightly soluble in water solid, which imparts a slightly basic reaction.
Marble Powder is made from calcium carbonate and is white in colour. The granularities of Marble powder can vary from 0 to 400 microns. It is a solid waste material generated from marble processing and can be used either as a filler material in cement or fine aggregates while preparing concrete. Marble powder can be used as an admixture in concrete, so that strength of the concrete can be increased.
Powdered Marble Dust can be used to make acrylic modeling paste, glue base gesso, and all water and oil-dispersed paints as well as to create a textured surface for drawing. It is made from pH-neutral basic calcium carbonate.
