The landslide occurred on April 2, 2017. The road has been closed since then and will be until further notice. Due to public safety and the location of the landslide, there will not be a temporary bypass or detour constructed at this time. The slide is not very active at this time but there is still some material sloughing off on occasion due to the nature of the slide and the type of soils that are out there.
Lincoln County has given the contractor, Condon-Johnson & Associates, Inc. (CJA) the notice to proceed. The contract time will begin on June 4, 2018. They will have 105 working days to complete the project. 105 working days will be at the end of October.
The Porcupine Bay Road will be closed to all traffic during the construction of this repair process.
For those of you that want to see the construction and what is going on, do so from a distance. Please do not go into the construction area due to safety reasons. It will be clearly marked. We will be updating this page with photos throughout the project. So check back frequently!
6/7/2018- Work has begun!
Video shot by Lincoln County Commissioner Rob Coffman.
7/19/18- Uphill side soldier pile wall is coming together…
8/7/18- Work has begun on the East side (downhill) soldier pile wall!
8/8/18- New drone video!
Wood Lagging is being installed on the East wall and permanent anchors also. Preparation on the West wall for shotcrete is happening. Prefabricated drainage mats are being installed over the wood lagging. Ready for shotcrete.
Shotcrete, also called (trademark) Gunite, concrete applied by spraying. Shotcrete is a mixture of aggregate and portland cement, conveyed by compressed air to the nozzle of a spray gun, where water is added. The wet mixture is then sprayed in place and may be carved or troweled almost immediately. For structural uses, shotcrete is usually applied over a framework of reinforcing bars and steel mesh. Because it can take any shape, is easily colored, and can be sculptured after application, shotcrete is used for a variety of fancy concrete structures, including artificial rock walls, zoo enclosures, canopy roofs, refractory linings, pools, and dams. It is sometimes used in tunneling to bind the walls of the tunnel to prevent leaks and fragmentation.
At about 11:45 a.m. on October 3, 2018, another slide took place inside the limits of the previous slide area. A significant amount of material ended up in Lake Roosevelt. Our geotechnical engineer is assessing the site for safety, damage to the constructed walls and stability of the existing slope. There were 3 pieces of equipment that were in jeopardy of the slide. They were moved to safety on October 4th. Work is continuing on the west wall. Progress on the east wall will take place after safety issues have been addressed.
Work continues on the West wall with sculpted shotcrete facing being applied. The next step will be to stain the wall to match the natural surroundings. We can’t wait to see the finished product!
Sculpted shotcrete facing is getting stained to match its natural surroundings. Behind this cool looking wall is an amazing amount of hidden necessities.
Since the new slide that occurred on October 3, 2018, work has been halted on the east soldier pile retaining wall (downhill side) due to slope stability and worker safety concerns. Due to the possibility of differing site conditions, there is an ongoing engineering investigation to determine if additional work may be needed to stabilize the existing slope and/or east soldier pile retaining wall.
Work continues on the west soldier pile retaining wall. The shotcrete fascia will be completed this week. At that time the project will be suspended until the contractor (Condon-Johnson & Associates) and/or our geotechnical firm (Budinger & Associates) formulate a solution to allow the project to proceed. The solution may be additional structural components to the existing structure or stabilizing the existing slope, either way, the project is suspended for now to allow proper planning and design to address the differing site conditions.
After a month-long Engineers investigation, due to slope stability, the contractor is back to work. They are installing ground anchors on the east wall. Anchors in Row B have been completed and they have started on Row C.
11/16-11/29- Work continues and the progress is looking good!
12/10- Commissioner Coffman did a new video!
12/13- Only 13 anchors remain to be done on Row C and then work will begin on Row D.
1/21/19- Row D is under way.
1/29/19- All permanent ground anchors have been installed as of January 15th. The contractor (Condon-Johnson & Associates, Inc.) is now preparing the east wall for the shotcrete fascia and the concrete gutter. Barring any unforeseen circumstances, the fascia and gutter should be completed by the end of February.
2/11- New video, Thank you Commissioner Coffman!
Due to inclement weather the project has been in suspension since 2/13/19. Starting on 3/11/19 the construction of the East wall shotcrete will resume and hopefully more favorable weather will allow the completion of the wall.
Work is progressing nicely at the project. The plan is to have everything prepped and ready to begin asphalting, striping, and signage in April. We are planning for a tentative May opening date.
Structural shotcrete is complete and the artwork is being done. Landscaping is currently being installed. Paving should be started by the end of this month. We are looking forward to seeing the final result.
Prepped and ready Asphalting begins It looks so good!
Construction has been completed and Porcupine Bay Road is NOW OPEN!
We would like to thank the public for your patience while we have gone through this process. We are very excited to have the road completed. Please go to the National Park Service Website for information on when the park and boat launch will be open. Below is a statement from the NPS from the ribbon cutting event.
“Staff at Lake Roosevelt National Recreation Area are working to have the Porcupine Bay boat launch open by Memorial Day weekend. Due to additional work required on the water system, the Porcupine Bay campground and day use area will remain closed until they can be safely opened for visitor use and enjoyment.” Dan A. Foster, Superintendent, Lake Roosevelt National Recreational Area

We would all recognize London' s famous Tower Bridge, some may have heard about Iron Bridge, but in general bridges are not obvious tourist attractions. They were built to serve a simple purpose - to join the opposite banks of a river. But despite their apparent simplicity, they can be highly complex, stunningly beautiful, wonderfully inspiring and definitely worth seeing.
Some people believe that bridges were the first structures ever built by humans. Because as people wandered through the countryside easy access across a river or ravine was more important than housing. Later bridges played an important part in establishing cities.
The world' s first Iron Bridge was erected in the English county of Shropshire in 1779. The following century produced a greater number of bridges than had ever existed before. Great Britain was then the world leader in the design and building of bridges. It is estimated that in the British Isles today there are over 200,000 road bridges and over 60,000 rail bridges.
Towering over the Thames
London' s Tower Bridge is definitely the best known and most admired of all Britain' s bridges. It is a symbol of the capital and instantly recognizable around the world. It is also the only bridge where one can have a look inside, where the massive machinery used to lift the bridge is on display. When it first opened, over a hundred years ago, Tower Bridge was raised over twenty times a day to let ships through. Nowadays it is raised only a few times a week and twenty-four hours notice has to be given.
Another, no less famous, is London Bridge. The present one, a very plain structure, is the fifth construction in this place. The first bridge was built of wood by the Romans between AD100 and 400. Later it was replaced by a stone one which, until the middle of the eighteenth century, was the only bridge in London. In 1967 it was sold to an American millionaire and re-erected in Arizona. Apparently the rich businessman thought he was buying Tower Bridge and it was only when he' d spent millions of dollars and the bridge was rebuilt that he discovered his mistake! In London the
present concrete construction was built replacing the old bridge stone by stone without interrupting traffic flow.
Suicidal suspension bridge
It is well worth venturing out of London to see three exceptional bridges designed by Isambard Kingdom Brunel. Probably the most spectacular of them is Clifton Suspension Bridge in Bristol. It was designed by Brunel when he was only twenty-four years old in 1829 and not completed until thirty years later, after his death. The over 213-metre-long structure was the longest suspension bridge in the world at the time. To this day this splendid structure inspires engineers and romantics - but is also very popular with people wishing to commit suicide. Special barriers designed to prevent people from jumping and signs suggesting contacting the Samaritans from telephone boxes on each end haven' t reduced the popularity of the place. On average someone jumps to his or her death almost once a month.
Another extraordinary bridge designed by Brunel is in Saltash on the outskirts of the city of Plymouth and joins Devon with Cornwall. Its two parts were assembled on the banks and then moved into position on pontoons. Brunel directed his army of workmen by a series of complicated signals, using numbers and flags. Over the next months the parts were lifted up one metre at a time to their final position by hydraulic jacks as the masonry was built up.
Brunel designed one more bridge about which all his critics were agreed - it would never stand. At first sight the bridge over the river Thames in Maidenhead does not look so impressive, but it is still the world' s largest brick arch. This bridge was the setting for Turner' s famous painting of the steam age called" Rain, Steam and Speed" . Today trains reach over 200 kilometres per hour while passing over it but the construction of the unrivalled engineer stays intact.
Scottish Eiffel Tower
There are many Scottish bridges which have earned their place in history. The Glenfinnan Viaduct in the Scottish Highlands was the first major structure built of concrete. The Tay Bridge, which joins Newport with Dundee, was at one point the longest bridge in the world. It measures over three kilometres and is still the longest of all bridges in the British Isles. But the most spectacular bridge in Scotland is the Forth Bridge, sometimes called the" Scottish Eiffel Tower" or the" Eighth Wonder of the World" - a hundred years ago it was described as" the uttermost example of ugliness" .
Of the many bridges spanning the banks of the River Liffey in Dublin, Ha' Penny Bridge, designed for pedestrians, is the most elegant. Its name means half penny, the fee one had to pay to cross it until early this century. Nowadays we can cross it for free. It was featured in the excellent movie Lulu on the Bridge. From here Mira Sorvino throws a blue stone and later jumps to her death.
New bridges are always being built throughout the British Isles. In May the new Millennium Bridge opened in London and in Dublin an extraordinary bridge in the shape of a harp is being constructed. And the future? In London' s Science Museum as part of an exhibition showing new uses of materials, it is possible to cross a bridge made of glass, which hangs on wires only one-and-a-half millimetres thick. The sky is the limit for the human imagination and who knows what the future may bring in terms of bridge design. But for the time being, if you' re visiting the British Isles spare a few moments to appreciate the bridges which have already been built.

Bending rebar is all about leverage.
How to bend rebar by hand. In this video, jim blodgett of roy, washington, shows you how to bend rebar pretty easily with a pair of steel pipes. You could easily bend 100 pieces of rebar within an hour. Insert rebar into the bars fixed on the wood.
Unless you work with the material regularly, chances are this is the method you will be using. 1/2 is pretty easy to do. Steel and steel alloy handles help provide strength and durability.
This connects the shell to the footing or ring beam. The speed of this portable bender is a major selling point. This hand held bender has an optional bending die and shoe cover for larger radius bends.
Lock the rebar securely in a vice and position it directly below the point you want to bend the rebar. It may prove impossible to bend a piece of rebar by hand, but with the extra leverage of a rebar bender, you can easily bend these tough steel rods into nearly any shape. Fortunately, in building a monolithic dome only a minimum of the rebar used generally requires bending.
Remember, though that there are significant structural codes to be followed in construction, which means that for projects beyond arts, the type of rebar is not. Do not heat rebar in order to bend. Place the rebar on the ground.
If you need to bend a couple pieces of rebar for a small concrete pour, you could go rent an expensive rebar bender, but if you want to save a few extra bucks, there’s a better way. This footer complete with rebar is ready for concrete. Insert the pipe on the rebar.
Put the rebar into a vise, lining up your future bend with the end of the jaws. We bend the rebar embedded in the footing down to get the airform over it. How to bend rebar by hand.
4.4 rebar cut & bend. Put the rebar in the vise, secure in place, insert a pipe with a diameter bigger than the rebar, and bend until it. The first thing to do before bending rebar is wearing safety equipment.
The 800w hydraulic press is also economical as it does not use a lot of power as compared to most other hydraulic presses. In order to bend rebar, you will need to hold one side of it in place, then pull down on the opposite end to bend it. If you only have a couple to make and the rebar is 1/2 or smaller then just fill the bucket up with sand and snap the lid on it.
The procedure of cut & bend as follow: The astm rebar bend test requirements at any given size are the same for each grade (although ductility, as measured by elongation in tensile test, decreases as strength increases). The vise's jaws should be positioned just below the point where you want to bend the rebar.
One contributor suggested that a rebar bending job can be completed by securing a bar in a vice, and adding heat, and using a torch to make the steel malleable. “torch it?” on this issue, we’ll borrow advice from the common diy guide, wikihow: When other bending angles are re q u i r ed, the o p e r ator must estimate the amount of lever movement needed to achieve the bend.
These 4 rebars must be fixed like the one below. Put a couple of cheaters on the rebar or leave it real long and just use muscle power to bend it around the bucket. Hand rebar cutters and benders allow for the manipulation of rebar to fit the job.
It can bend rebar, steel rods and steel bars up to ⅝” in diameter. Or use anything else that is round that is laying around. As such, it can easily graze you or hurt you if it falls on your foot or.
Bending rebar 1 ⁄ 2 inch (1.3 cm) or smaller. Step 2 put on a pair of leather work gloves to protect your hands. Rebar is sharp and heavy.
Then use a pipe to bend it. Workers who cut or bend rebar may face hazards from stressful hand & wrist activity. How to bend rebar using old school style.
The latter is a simple piece of equipment that will hold the rebar in place and will make it easy to make sure that it will be in a stable position. Larger sizes have to be bent using special equipment for example hydraulic shears. In order to use rebar in ways other than as a straight medium for reinforcing concrete, it may be necessary to learn the best way of bending rebar by hand.
Choose the reasonable size of the rebar if you bend by hand for smaller projects needing to be bent into different shapes, you can opt for thinner rebar, such as a ¼ inch design. To bend rebar in this method you would need a lengthy wood set up in a standing position and 4 small rebars fixed on the wood. As an alternative, you can also bend the rebar by hand with the help of a vise.
This quiet, polite, unassuming device turns mean when it comes to bending rebar. Later, we bend it up so that the rebar becomes included in the concrete shell. Heating the metal slightly will make it bend more easily.
Using a long metal pipe with a large enough internal diameter, place the rebar into the pipe stopping about six inches from the point you'd like to start the bend. Rebar cut & bend works shall be performed in 2 shifts (day and night) depending of the activity. The safest and easiest way of bending rebar by hand is to encase it inside two pieces of metal piping — a shorter piece, and a longer piece.
Performing stressful hand activities while cutting or bending rebar can lead to tendon inflammation (tendonitis) in the hand, wrist, or shoulder, or carpal tunnel syndrome. Now that you have a piece cut to length it is time to bend it. Rebar that has a diameter of up to 1/2 inch can be cut and bent by hand.
But it takes a little knowhow to get the measurements right. As the vise holds the rebar in place, it bends right where the vise stops and the free section of the bar begins.


The unique KTZ system, there is no other system like it.
In collaboration with Kliko, we developed the KTZ system, an exceptionally effective, reliable and safe waste collection system for underground and above ground containers.
The system utilises the latest technologies fully tested to provide a user friendly, robust system and consists of two main components.
First, the underground waste container, stored invisibly underground with a waste litter pillar above, the KTZ system container requires no electrical or hydraulic power installation meaning that the system is pretty much maintenance-free and installation is as simple as it can be. Additionally, a range of above ground containers are available.
Second, the KTZ collection vehicle, an exceptional sophisticated vehicle, developed by Terberg Machines and fitted with an automatic side-loader allowing 5m3 inner containers to be emptied.
The KTZ system consists of two main components;
Containers: The under-ground waste container, stored invisibly underground complete with an above ground waste insertion pillar. The KTZ system container requires no electrical or hydraulic power installations meaning that the system is largely maintenance-free and thus provides a considerable saving in capital outlay. The above-ground container options have been specially designed for the KTZ system and are also compatible with the side loading KTZ system.
Collection Vehicle: The KTZ collection vehicle, an exceptional sophisticated vehicle, developed by Terberg Machines and fitted with an automatic side-loader allowing above and 5m3 under ground containers to be emptied automatically by just one driver/operator. The underlying principles for the KTZ system design are to ensure safety and offer the best working conditions possible. The collection system co-developed by Terberg and Kliko offers municipalities, architects and town & country planners possibilities that have not been available previously. The compact design and efficiency of the KTZ system make the solution possible, not just physically but financially.


Traffic congestion is one of the most prevalent and vexing characteristics associated with major cities every city tries to manage the traffic congestion depending on the population, geographical, cultural, and political and of course, most important the economic background of that city/state. Congestion and traffic pollution has been a major problem in new york city for years there have been many laws, tolls, and fines implemented over the past few decades to try and fix the problem yet, congestion still exists congestion occurs when there is overcrowding on roadways that's. Traffic congestion is a problem which faces many large cities around the world many cities face the problem of traffic gridlocks especially during rush hour periods when employees are rushing to or from work in toronto, this is a major problem which threatens the long term economic growth of canada.
traffic congestion and parking difficulties congestion is one of the most prevalent transport problems in large urban agglomerations, usually controlling the access to a congested highway by letting automobiles in one at a time instead of in groups the outcome is a lower disruption on. Workers who experience traffic congestion for more than three times a week report significantly higher level of stress but traffic problems instead can feed a sense of helplessness she says: i grew up in toronto and i lived in new york before this so i'm used to the big cities and the traffic. Traffic congestion is not primarily a problem, but rather the solution to our basic mobility problem, which is that too many people want to move at the same times each day why because efficient operation of both the economy and school systems requires that people work, go to school, and even. The problem is clear: traffic congestion will become significantly worse and more widespread without big changes in how people and products get around traffic comes to a stand still on the northbound and the southbound lanes of the interstate 405 freeway near los angeles international aiprort.

The problem with light rail transit (lrt) is simple when the roads are congested to the point of standstill traffic, building a rail-road line right smack down the centre of it if a massive subway project were to begin in toronto, the money spent would immediately be recirculated throughout the city. Within canada, toronto has one of the busiest roads short distances become longer when travelling by own transport however, everyone needs a more permanent solution to the traffic problem traffic not only leads to delays but also causes wastage of time and productivity. The report named many culprits for toronto's productivity problems: traffic congestion due to overreliance on private cars, railway capacity that was pathetically low, poor regional transit integration, underdeveloped public transit, and the worst federal government support for transportation in the.
Toronto traffic problems abstract toronto, which is the provincial capital of ontario, is one of the fastest growing cities in the globe, and has an one of the most palpable reasons for the high traffic congestion in toronto is the large number of private cars that owners utilize to commute to work. Traffic congestion is caused by commuters travelling to work one of the main reasons for traffic jam is that the majority of people prefer using their own cars instead of public in conclusion, the problem of traffic congestion can be tackled by improving public transportation, changing our habits and by. School-related traffic congestion and the risks such congestion poses to the safety of the students, teachers, parents, residents, and motorists in and around school locations is a significant problem in communities both throughout the united states and abroad the most obvious cause of traffic. Traffic congestion is a condition on transport networks that occurs as use increases, and is characterized by slower speeds, longer trip times, and increased vehicular queueing.
The major cause leading to traffic congestion is the high number of vehicle which was caused by the population and the development of economy to solve this problem, the government should encourage people to use public transport or vehicles with small size such as bicycles or make tax on private. Traffic congestion may be considered a problem, by many, they often fail to see the extent of its impact on the community and country demand spreading there are many methods adopted in different countries to spread the traffic during peak hours since it is when large numbers of people. To ease traffic congestion, it should, at the same time, push for the development of franchised bus services and improve the attractiveness of other forms of public transport for example, the government can encourage minibus operators to ensure their vehicles have a barrier-free design.

Post Tension - FAQ
What Does Post-Tensioning Mean for Residential and Commercial
What is a Post-Tensioned Foundation?
- Eliminates contraction joints
- Minimizes the size an number of expansion cracks
- Eliminates cracked and uneven floors and walls.
- Far superior foundation to traditional floating slabs.
Simply put, Post-Tensioning is a method of reinforcing concrete, masonry,
and other structural elements by prestressing the structural element during
the construction phase for the purpose of counteracting the anticipated
external loads that it will encounter during its lifecycle.
What are the two methods of prestressing?
1) Pre-tensioning -- This method consists of stressing the reinforcing inside
of large steel buttresses, and then casting the concrete around the
reinforcing. This method can only be done at a precast manufacturing facility
and requires the completed prestressed concrete members to be trucked out
to the job site and then assembled.
2) Post-tensioning -- Reinforcing is simply installed on the job site after the
contractor forms up the slabs or constructs the walls. The reinforcing steel
is housed in a sheathing or duct that prevents the steel from bonding to the
concrete so that it can be stressed after the concrete cures (hardens).
Using the posttensioning method enables a builder to get all the advantages
of prestressed concrete or masonry (described below) while still enabling the
freedom to construct the member (slab, wall, column, etc.) on the job site.
Why Does Concrete and Masonry Need to be Reinforced?
Concrete, masonry, and most cement based products are very strong in
compression. However, concrete is relatively weak in tension. Conversely,
steel is very strong in tension. Combining reinforcing steel with concrete or
masonry results in a product that can resist both compressive and tensile
forces. Also, compressing the concrete increased the tensile bending
strength of the concrete so that a designer can achieve longer spans with
thinner concrete sections. Compressing the concrete also helps resist the
development of shrinkage cracks.
What Kind of Materials are Used in Post-Tensioning?
Post-tensioned reinforcing consists of high strength steel strands or bars.
Typically, strands are used in horizontal applications like foundations, slabs,
beams, and bridges. Bars are used in vertical applications like walls and
columns. A typical strand has a tensile strength of 270,000 psi and a typical
bar has a tensile strength of 60,000 psi. Strands typically have a diameter of
1/2 inch and are stressed to a force of 33,000 pounds using a hydraulic jack.
What are the uses and advantages of using post-tensioning?
Post-tensioned reinforcing has been used for many decades in bridges,
elevated slabs (parking garages and residential or commercial buildings),
residential foundations, walls, and columns. The use of post-tensioned
reinforcing can result in thinner concrete sections, longer spans between
supports, stiffer walls to resist lateral loads, and stiffer foundations to resist
the effect of shrinking and swelling soils. The additional advantage of putting
the concrete into compression can be used to construct slabs and walls that
have fewer visible cracks that can allow the passage of moisture and

Thanks to the two-year shut down of Bertha (the giant tunnel boring machine), the opening of the Highway 99 tunnel will now be delayed until 2019. When the project was in its planning stages, officials promised it would open by late 2015.
Unfortunately, that’s not the only bad news to come out about the project. The Washington Department of Transportation (WSDOT) delay will also burden taxpayers with at least an additional $223 million in cost overruns.
However, $223 million in cost overruns is a rosy estimate. As Shift pointed out, the estimate is based on the assumption that tunnel contractor Seattle Tunnel Partners fails to win claims against the state that exceed $200 million. The dispute is currently in court.
It’s important to note that a dispute review board has already ruled that the responsibility for Bertha hitting a pipe (and, consequently causing the breakdown/delay) lies with the state, not Seattle Tunnel Partners. Considering that result, it’s well within the realm of possibility that Seattle Tunnel Partners will win its lawsuit.
But, a possible win in the ongoing court case is not the only possible way the cost overruns can grow beyond $223 million. In fact, according to KIRO Radio’s Dori Monson, the cost overruns already exceed that amount.
Monson argues that the Highway 99 tunnel project is actually $523 million over budget. He points to the following statement made by former WSDOT Secretary of Transportation Paula Hammond prior to the project’s launch:
“The project may cost $2.8 billion. We believe we could bring it in for under, although we’re not going to talk too much about that until we get further in our design…”
You see, WSDOT says that the original cost of the project was $3.1 billion. But, prior to the start of the project, WSDOT officials like Hammond said the project would cost $2.8 billion. WSDOT explains the extra $300 million by saying it would pay for entrance and exit ramps — as if entrance and exit ramps were not considered in the project’s planning phase (which would just make them incompetent).
So, just to wrap-up what we know, WSDOT officials say the original cost of the project is $3.1 billion. But, according to statements made by the WSDOT officials at the time, the original cost was $2.8 billion.
That, of course, means the project is actually $523 million over budget not — as WSDOT now claims — $223 million over budget.
Ladies and gentlemen, the incompetence of WSDOT for all to see.

Floating Floor Systems
5The Warmafloor Floating Floor system is for use when underfloor heating is to be installed on concrete floors where a dry finish to the floor is required, not a screed topping.
The maximum heat output of 75 W/m2 is less than for a screeded floor system, so the Floating Floor system is predominantly for use in new buildings, where the heat requirements of the building are less.
This system relies on the floor being flat and level and involves pre-grooved polystyrene floor insulation panels, fitted with pre-grooved metal diffusion plates into which the underfloor pipework is fitted.
The installation involves laying the Floating Floor panels to cover the complete floor area.
At door openings, floor support battens will need to be fitted as in a normal Floating Floor. Warmafloor PB pipe is then clipped into the di¢usion plates, circuited to design requirements and run back to the manifold. Flooring is laid then on the system – chipboard, plywood or dry screeding flooring panels such as Fermacell – and then the final floor covering is laid.
This system offers complete access to the installation for any component repair or replacement, by lifting the flooring.
Panels available in:
25mm, 35mm, 50mm and 75mm thick

The Minister for Municipal Administration, Rural Development and Implementation of Special Programme, S P Velumani headed the review meeting for the proceedings of the Smart City plan and the Amrut Plan implementation in Corporation and Municipality areas in the State, at the MRC Nagar Administration Block, today.
The Minister enquired about the proceedings of the project implementation in the Smart City which is estimated to cost Rs.11,296.30 crores for 326 projects and also about the status of implementation of the Amrut plan in 12 corporations, 15 municipalities and 1 Town Panchayat costing Rs. 11,441 crores for 445 projects. S P Velumani instructed the authorities to speed up the completion of the ongoing projects and a faster initiation of the remaining projects.
Addressing the meeting, the Minister urged that proper water distribution must be ensured and immediately implemented. "The water storage resources needed to be properly maintained and in case of blockage or damages in pipelines, they need to repaired with immediate effect," he reiterated. He also ordered immediate inspection of the condition of all motors and to replace worn ones. He also asked the officials to ensure the generators were ready to use, at all times. In case of faults, he urged them to hire from private entities to ensure seamless distribution of water.
S P Velumani asked the authorities to provide clean chlorinated water regularly, check water reserves,clean nearby ponds and wells if there is decrease in water levels, check the quality of water and ensure continuous water supply to the public. He also asked to check the distribution of water through lorries where pipelines were not possible.
The Minister instructed authorities to arrange for registration of complaints through phones and computers. On receiving the complaints, he instructed that a meeting be held every evening to plan and sort the complaints quickly. He insisted on strict action to be taken against individual houses that use motors to pump copious amounts of water, leaving others in the neighbourhood suffering from water scarcity. He also instructed the Town Panchayat Assistant Director to conduct a meeting with all the Assistant Engineers and officials to ensure drinking water distribution in town Panchayat areas. He ordered for distribution of drinking water to the poor and needy in remote areas through water lorries.
S P Velumani also asked the Corporation and Municipality officials to use media to spread awareness on the importance of using water wisely and asked the public to support the cause to ensure there is no scarcity.

Types of Milestones on the basis of road
How do you know if a highway, you are travelling on, is a national highway, a state highway or a district/city road.
You would have noticed the different colours of the milestones alongside a road. In India, on administrative basis, there are 3 kind of roads – the one maintained by the Central Government bodies like NHAI, the respective state government and the district administration.
So the national highway has a white and yellow milestone.
A state highway has a white and green milestone.
And a city road has a black and white or simply white milestone.
A road constructed under “Pradhan Mantri Gram Sadak Yojana” will have orange and white milestone.

HVAC systems are used to provide optimal thermal comfort and air quality in indoor facilities. These system uses approx. 70% of the building energy, in that chiller uses approx. 30% energy for producing chilled water for air conditioning.
In current systems, user sets the thermostat and chiller produces chilled water based on that. Let say that outside weather is going to change ±3 °C in few hours. Due to which there is a slightly discomfort to the users as the have to again change the thermostat for maintaining the optimal comfort.
Designing a closed loop system where consideration of outside weather parameters can help in energy saving and maintaining optimal thermal comfort through the day.

Hurricanes are Categorized from 1 to 5 according to what is known as the Saffir-Simpson Scale.
Storm surge is the combination of a bubble of ocean water raised above the mean water surface by low pressure contained within the eye and a delicate balance the wind pressure that counters the force gravity applied to a wall of moving water. As the wind speeds vary, the height of the wall of water increases or disperses over open water. Momentum would not be a factor as the wind force providing the push decreases dissipation storm surge off to the sides of the hurricane would occur.
Storm tide is the combined factors of surge and the level of the tide at the hurricane's landfall.
(Courtesy NOAA/Neal Dorst)
Mechanics of the Storm Surge
At least five processes can be involved in altering tide levels during storms. These include the pressure effect, the direct wind effect, the effect of the earth's rotation, the effect of waves, and the rainfall effect (Harris, 1963). The pressure effects of a tropical cyclone will cause the water level in the open ocean to rise in regions of low pressure and fall in regions of high pressure. Wind stresses cause a phenomenon referred to as "wind set-up", which is the tendency for water levels to increase at the downwind shore, and to decrease at the upwind shore. This effect is inversely proportional to depth (Harris, 1963). Wind set-up on an open coast will be driven into bays in the same way as the astronomical tide.
Surge and wave heights on shore are affected by the configuration and bathymetry of the ocean bottom. A narrow shelf, or one that drops steeply from the shoreline and subsequently produces deep water in close proximity to the shoreline tends to produce a lower surge, yet a higher and more powerful wave. This situation is seen along the southeast coast of Florida. The edge of the Floridan Plateau, where the water depths equal 91 meters (300 feet), lies just 3 km off shore of Palm Beach, Florida; just 7 km off shore, the depth plunges to over 180 meters (Lane, 1980).
Conversely, coastlines such as those along Florida's Gulf coast and the Florida Keys have long, gently sloping shelves and shallow water depths. The 180 meter (600-foot) depth contour followed southward from Palm Beach County lies more than 30 km to the east of the upper Keys. On the Gulf side of Florida, the edge of the Floridan Plateau (91 meter depth) lies more than 160 km offshore of Marco Island in Collier County. Florida Bay, lying between the Florida Keys and the mainland, is very shallow; depths typically vary between 0.3 and 2 meters (Lane, 1981). These areas are subject to higher storm surge, but smaller waves.
This difference is because in deeper water, a surge can be dispersed down and away from the hurricane. However, upon entering the shallow, gently sloping shelf, the surge can not be dispersed away, but is driven ashore by the wind stresses of the hurricane. Topography of the land surface is an important element in storm surge extent. Areas such as those seen in southern Florida where the land lies less than a few meters above sea level are at particular risk from storm surge inundation.

The U.S. is falling apart.
To prosper and grow, and live safely, the U.S. must start rebuilding the most basic infrastructure of the country.
You cannot leave a country of more than 310 million people unattended for 30 years without dire consequences. But that’s where we’re at. Roads crumble, bridges crack, sewers break, water pollutes. People get hurt or sick.
Problems are everywhere. For years the old ramps on the Chicago Circle Interchange have stalled close to 300,000 vehicles a day, with an estimated 25 million hours in delays per year.
The Industrial Canal Lock in New Orleans is critical to commerce, carrying 20 million tons of cargo a year. But the 87-year-old lock is undersized, and vessels wait 36 hours to navigate it.
As much as 18% of Atlanta’s drinking water was hemorrhaging through leaking pipes, as a recent drought had residents rationing. Estimates are that municipal lines running beneath U.S. streets lose massive volumes of water.
The Robin Hood Tax could raise billions every year to address America’s crumbling infrastructure. These projects could employ millions through direct hiring or as a result of increased demand of suppliers. America’s jobs crisis could be addressed at the same time we desperately play catch up on the country’s declining system of roads, waterways and bridges.
Who leaves behind a mess like this?
It’s 30 years and the clock is ticking. The need to repair and upgrade infrastructure is obvious to all. Way overdue.
Across the nation, in every region, every city, every locale, America is crumbling. An 80-year-old, over-stressed system of levees and spillways on the Mississippi River shut down the country’s greatest river way. Ancient water lines and sewer lines rupture in cities across the country-- the nation’s capital included. Antiquated drainage systems lead to devastating floods and sewage spills.
The U.S. is spending a miniscule 3% of its GDP on infrastructure repair and renewal. While other countries plow ahead with high-speed rail projects, here we are bogged down in debate on its soundness. Meanwhile, interminable lines of car and truck traffic grow longer – their fired-up engines burning fuel and burning out the environment- as the list of cities mired in gridlock gets longer.
At this rate, Americans will start turning to bottled water, if you can afford it, as H2O from the tap becomes unreliable. The roads are a mess: interstates crumbling, urban road ruts and holes the norm, rural road maintenance elusive. Bridges will collapse and not be rebuilt. Try the long way around.
A badly-needed new national electric grid will not be developed. Nor will a state-of-the-art satellite air traffic control system.
In the next 30 years, there will be almost 100 million more people living in the U.S. But the infrastructure will not support them all.
A Robin Hood Tax could start funding infrastructure projects without delay and start rebuilding America so that we do not leave a battered and broken country for the next generation.
And more. Millions of quality jobs in an array of planning, manufacturing and construction for infrastructure would be created, a double dividend given the enduring unemployment, dearth of opportunity for young adults and dead-end, low-pay service jobs that define our economy today.

Bay Bridge West Tower - sans road and cables c1935
This tower sure turned out well - with baited breath and the patience of Jobe, I look forward to seeing the new tower on the Eastern span rise...a new landmark and symbol of the gateway to the City by the Bay
The West Tower of the Bay Bridge rises to 281 feet, and its concrete anchorage was sunk 235 feet below the water line. Its total height is taller than that of the largest of the Pyramids of Egypt.

Nantes − Saint Nazaire Port’s dredging policy is based on delivering optimal maintenance of channel depth according to expected traffic levels, while also limiting the impact of such operations on the estuarine environment. This strategy relies on making due allowance for the hydrology of the River Loire, since the River’s flow has a significant effect on inputs of sediments and the conditions for their removal. The tidal conditions also play a decisive role in terms of the re-suspension or the deposition of suspended matter present in the area of maximum turbidity, resulting in the sedimentary deposits on the bed of the Estuary.
In addition to the three hydrographical survey craft tasked with mapping the bed before and after each intervention, Nantes − Saint Nazaire Port employs three dredgers: the Samuel de Champlain, the first mobile suction dredger to be fitted with an LNG propulsion system, which is leased from the GIE Dragages Ports Port Dredging Group, the André Gendre, a stationary suction dredger, and the Milouin, which is equipped with a low-pressure water injection system.
The dredging operations are subject to authorization under the relevant water management regulations. Nantes − Saint Nazaire Port has notably been granted authorization to carry out maintenance dredging and disposal-at-sea operations, in the form of a Loire Atlantique and Vendée Inter-Prefectural Authority approval dated 24th April 2013, for a period of 10 years. That approval requires that regular environmental assessments be carried out in respect of the dredging and disposal operations (quality of the sediments, water quality, benthic fauna, macroalgae, marine habitats), and that an interim review be conducted after 5 years of operations. The assessments carried out also contribute to a better understanding of the Loire Estuary.
The average annual volume of dredged materials for the entire Loire Estuary is approximately 6.4 million m3. That volume is less than the average volume authorized under the Inter-Prefectural Authority approval granted in 2013 (8.5 million m3). The sediments present in the Loire Estuary are mainly muddy (in the proportion of 80 to 90 %), but the sand content is locally high in the Nantes channel. The proportion of sand has been tending to increase over the past few years, marking its return some 25 years after aggregates stopped being extracted from the bed of the River Loire upstream from Nantes. Because of the low level of chemical contamination in the sediments, it is considered that there is a low risk of pollution of the water and living habitat in the zones impacted by the resuspensions of sediments resulting from the dredging operations carried out by the André Gendre and by the Milouin, and from the disposals at sea by the Samuel de Champlain in the La Lambarde disposal zone.

About the Book:
Engineering rock mechanics is the discipline used to design structures built in rock. These structures encompass building foundations, dams, slopes, shafts, tunnels, caverns, hydroelectric schemes, mines, radioactive waste repositories and geothermal energy projects: in short, any structure built on or in a rock mass. Despite the variety of projects that use rock engineering, the principles remain the same. Engineering Rock Mechanics clearly and systematically explains the key principles behind rock engineering.
The book covers the basic rock mechanics principles; how to study the interactions between these principles and a discussion on the fundamentals of excavation and support and the application of these in the design of surface and underground structures. Engineering Rock Mechanics is recommended as an across-the-board source of information for the benefit of anyone involved in rock mechanics and rock engineering.

To be able to choose the best roofing products for Michigan, homeowners need to take into consideration a variety of factors – here are the most important aspects to consider when choosing the most suitable materials for your roof.
Michigan is located in the area of the Great Lakes and it consists of two large peninsulas separated by the Straits of Mackinac and lots of other, smaller and larger islands. The geography of the peninsulas is varied, with not only lakes, marshes and forests, but mountains as well.
The climate of the state is predominantly continental, with precipitation distributed quite evenly throughout the year, with hot summers and cold winters, but has two distinct climate zones, a warmer area in the southern and central parts and an area with short summers and very harsh winters in the north.
These climate variations mean that the roofing materials chosen need to be able to withstand harsh weather, be it scorching heat, strong solar radiation, heavy rain or thick snow. A good roof in Michigan needs to keep the interior of the building cool in summer, it needs to retain the heat inside in winter and it needs to provide suitable protection against moisture as well, and is usually installed by a contractor experienced in roofing Lansing Michigan homes.
Most roofs in Michigan are sloping roofs that permit the water coming from either rain or snow to run down on the surface of the roof without accumulating. The best roofing products in the area are materials that work on steep roofs and that come with superior water-resistance features as well.
Buildings that have thicker or brick walls can sustain the weight of heavier roofs, such as clay or slate, but the owners of lightweight constructions need to pay special attention to the weight of the roofing materials chosen, metal roofs and asphalt roofs being the most suitable solutions for these buildings.
Roofing materials show considerable variety in terms of pricing – natural materials, such as slate, wood or clay are the most expensive materials, while asphalt shingles and metal are among the cheaper options.
The Best Materials to Choose From
Here are a few of the most common types of roofing materials used on Michigan roofs:
- Asphalt shingles – preferred for their affordability, resistance and durability, asphalt shingles are among the most popular and most affordable roofing materials used in Michigan. Available in more simple, cheap, 3-tab varieties and in slightly more expensive architectural versions that come in more sizes, colors and textures, asphalt shingles come with long warranty periods and they offer durable and attractive protection for your home.
- Metal roofs – another great, weather-resistant solution that comes with superior fire-resistance and increased durability. Metal roofs are available in a wide range of colors, they are lightweight, easy to maintain and require almost no maintenance at all.
- Slate – heavy and not cheap at all, slate is a natural material of unparalleled beauty that can last for over 50 years and is resistant to both moisture and fires.
The best roofing products for Michigan homes are the materials that are suitable for the climate of the area, for the features of the building and for the aesthetic preferences and the budget of the owner – just weigh your options, factor in every important aspect and you will surely make the best choice.


Traffic lights on railway transport
The traffic lights by appointment are divided into the following types:
1) entrance – allowing or prohibiting the train to follow from the stretch to the railway station;
2) weekend – allowing or prohibiting the train to go from the railway station to the stage;
3) route – allowing or prohibiting the train to proceed from one area of the railway station to another;
4) checkpoints – permitting or prohibiting a train to proceed from one block-section (inter-station haul) to another;
5) covers – for fencing the intersection of railways in one level by other railways, tram tracks and trolleybus lines, drawbridges and ections that pass with a conductor;
6) barriers – requiring stopping in case of danger to traffic arising at railway crossings, large man-made structures and landslides, as well as fencing trains for inspecting and repairing wagons on station railway tracks;
7) precautionary – warning of the indication of the main traffic light (entrance, passing, barrier and cover);
8) repetitive – for notification of the permissive indication of the output, route, entry (exit), technological and indication of the hill, shunting traffic lights, when under local conditions the visibility of the main traffic light is not provided;
9) locomotive – to allow or prohibit the train to follow the stretch from one block to another, as well as a warning about the indication of a traffic light, which the train is approaching;
10) shunting – permitting or prohibiting the production of maneuvers;
11) humps – allowing or prohibiting the dissolution of cars from the hill;
12) entry (exit) – allowing or prohibiting the entry of railway rolling stock into the production area and exit from it on non-public railways;
13) technological – allowing or prohibiting the supply or cleaning of railway rolling stock when servicing objects located on non-public railway tracks (wagon tippers, car scales, devices for restoring cargo flowability, discharging devices, etc.).
One traffic light can combine several appointments (input and output, output and shunting, output and route, etc.).
Light emitting diodes or incandescent lamps are used as light sources in traffic lights.
Traffic lights are used lens or floodlights; by location they are divided into mast, dwarf, as well as installed on bridges, consoles, trusses of bridges, walls of tunnels, and on railway tracks of non-public use also on the walls of industrial premises.
Signal lights at traffic lights are used: continuously burning, normally non-burning, non-blinking and flashing (intermittently lit and extinguished).
Normally non-burning signal lights of the traffic light in areas equipped with automatic blocking, light up when the train enters the block section in front of it and go out after the train leaves the block section.
The traffic light should be provided with a letter plate containing its designation. Auto-blocking traffic lights are denoted by numbers, all other traffic lights – by letters or letters and numbers. On double-track and multi-track hauls of newly-equipped permanently operating devices for organizing movement on the wrong railway track by locomotive traffic lights, the letter plate must be provided on the reverse side of the masts of traffic lights as well.
The main values of the signals given by traffic lights (regardless of the installation location and their purpose) are as follows:
1) one green light – movement is allowed at a set speed; the next traffic light is open;
2) one yellow flashing light – movement is allowed at a set speed; the next traffic light is open and requires it to be traversed at reduced speed;
3) one yellow light – movement is allowed with a readiness to stop; the next traffic light is closed;
4) two yellow lights, the upper one of which is flashing – the traffic light is allowed to pass at a reduced speed; the train follows a turnout switch; the next traffic light is open;
5) two yellow lights – a traffic light is allowed to pass at a reduced speed and ready to stop at the next traffic light; the train follows a turnout switch;
6) one red light – stop! It is forbidden to pass the signal;
7) one moon-white light – it is allowed for the shunting train to proceed with the shunting traffic light and further to be guided by the readings of passing traffic lights or directions (signals) of the head of the maneuvers;
8) one blue light – it is prohibited for a shunting train to proceed with a shunting traffic light. The use of these signals at traffic lights for various purposes is provided for in the relevant paragraphs of this annex. The order of application of these signals in other cases not covered by this annex with

The ever-increasing urbanization has not only changed our landscape and living condition, but has also placed a growing demand on the infrastructure needed to support it. As a result, a great deal of attention has been placed on developing technologies capable of operating in these increasingly complex environments. In the field of underground pipe installation, horizontal directional drilling (HDD) has become an essential resource.
Developed from the directional and deep drilling technologies, HDD is the ideal steerable drilling method for the trenchless installation of pipes and cables. Utility and communication providers swear by the benefits of HDD technology because of its capability to provide them with numerous customized solutions for virtually any problem. Because of its many applications, it is necessary to systematically capture and outline the full range of the HDD technology, so that it can be effectively communicated to the engineers and decision makers of today and tomorrow.
This book "Trenchless Technology for Installation of Cables and Pipelines - 2ndVolume: Horizontal Directional Drilling" is extensively devoted to this particular issue. Developed by the pipeline design specialists at S & P Consult GmbH in Bochum Germany, the book covers and highlights every detail of the HDD process. This comprehensive reference book is regarded as the absolute standard within the industry, and is thus a valuable guidance and decision making tool.

Port Chester residents to vote on 2018 PCMS capital project
The Port Chester School District asks community residents to vote on a vital, comprehensive $12.5 million BOND PROJECT for much-needed renovations to Port Chester Middle School’s building exterior on Tuesday, FEBRUARY 6, 2018. This project primarily addresses the recent emergency safety work and necessary reconstruction at Port Chester Middle School for a long-term, safe and cost-effective solution.
The PCMS Safety Project will resolve emergency safety concerns by removing the exterior concrete cantilevers, repairing pedestrian bridges and replacing stairwell fire safety doors. The district/school will see an annual 8% energy savings, thanks to the replacement of the 50-year-old single-pane windows with state-of-the-art energy-efficient insulated windows. A smaller portion of the project also addresses two delayed projects on other campuses: installing ADA-compliant hand rails at Edison School and upgrading the high school auditorium’s audio system.
Port Chester Middle School is a National Blue Ribbon award-winning school (2005), that currently serves approximately 1,000 students in grades 6-8. The Board of Education approved the Bond Project at its December meeting and now shares it with district residents for their consideration this winter season.


We are specialists in the supply and install of rubber playground mulch in Alwoodley LS17 7 and we can offer top quality installations. This type of safety surfacing is great for play areas and parks, due to the safety features included. Rubberised mulch is a soft surface, which makes the children much safer if they fall. The depth of the rubberised mulch is dependent on the height of play equipment which the surfacing will be installed beneath - this is known as the Critical Fall Height (CFH). A certain depth will be required to ensure the safety of children.
Rubber playground mulch is well-liked in parks and other recreational areas due to the natural appearance. For more details on the depth, please click here https://www.rubberplaybark.co.uk/depth/west-yorkshire/alwoodley/ The safety surfacing is available in a variety of different colours in order to meet specific requirements. Feel free to get in touch with our team if you'd like an idea of costs to install this surface type.
Bound rubber mulch materials are produced with recycled vehicle tyres, and they are typically installed for local play areas closest to you in Alwoodley. This surface is designed to look comparable to wooden chippings since the rubber tyres are crumbled into little pieces. They are then combined with a specialist glue and laid onto the elected surface area with the required design and style. The shredded flooring is a preferred option for children's play areas, in addition to many other exterior places.
Just like wetpour, this glued rubberized mulch can be applied in an assortment of depths. To find out about the installation, please click here https://www.rubberplaybark.co.uk/installer/west-yorkshire/alwoodley/ The thickness of the surfacing is dependent upon the Critical Fall Height from the play area features. The tests are completed to British Safety Standards. Various features including play constructions and climbing frames can often get the play bark surfacing laid around them. Together with presenting top rated safety features, the colour choices and specification are excellent for current rustic designs and timber features.
With regard to facilities with existing outdoor furniture and structures in Alwoodley LS17 7 we can install the rubber surfacing to fit with them. You might have equipment like climbing structures, roundabouts, picnic benches and slides, and we can fit around these.
Our own bonded rubber bark is specifically created to have resilient strength and durability. Even in playgrounds that are used frequently, the bonded mulch flooring is resistant against damage and wear. The impact absorbing qualities create improved safety qualities for kids. It has been often constructed to be an impact absorbing surface type under playground apparatus. In addition, it creates a good looking and decorative specification for community areas and pathways.
Open parks and leisure spaces nearby will occasionally have the bonded mulch flooring laid to make a comfortable walkway through woods and grassy surfaces. These can be used for golf course pathways and other outside areas to cushion players' bones when walking around. To learn more about the pathways please visit this page https://www.rubberplaybark.co.uk/use/walkways/west-yorkshire/alwoodley/ Regular brushing should really be sufficient to help keep the flooring totally free of grime and rubbish. The upkeep may then stop litter from being stuck in the gaps of the flooring system. We recommend keeping the flooring as fresh as possible to make sure it’s still safe at all times.
We can carry out the installation of safety surfaces that include wet pour, rubberised mulch and lawn mats meant for recreational places and their surrounding areas in Alwoodley. It's important for children’s playground flooring to meet standard safety laws; our safety floors see to these types of specifications for example the Critical Fall Height specification. This play area flooring feature will be made permeable to allow them to be used in any climate mainly because standard water moves within them successfully. For play-area surface types that demand a more natural appearance, rubber mulch flooring is usually installed to accommodate the natural surroundings.
Please contact us through our enquiry box today if you would like to discuss prices for installing rubber mulch surfaces in Alwoodley LS17 7 .
