Clay Tennis Court Construction

Posted on by blogger

The very name of clay court reminds you of French open, Italia Open and the god of clay court – Rafael Nadal. The concept of clay courts is highly variable in terms of materials and the methods of clay tennis court construction, so an in-depth know-how is an utmost requisite. In many countries including France and United States the so called Clay Courts actually may not contain Clay at all. The reasons why they are called so are because they tend to behave very much similar to a clay court. Today the fast-dry type courts are very popular due to their building cost and low maintenance. These are known to be the Synthetic Clay courts. When deciding among the Natural and Synthetic courts there are few points that need to be taken care of.

First thing to check is the availability of synthetic materials in your locality. For example if good quality clay is available then it might be cheaper to build a clay court than importing synthetic granules to build a court.

The climate also plays an important role. As natural clay tends to hold and capture moisture for a long it cause sever building damage if the place you are staying has far amount of precipitation.

Cost of maintenance, a clay court with surface level drainage system will definitely cost less than maintaining a below surface level irrigation for synthetic court. Not to be forgotten the availability of water source for natural clay court.

Following are the tips for constructions:

Firstly check with the authorities if a special permission will be required to build a tennis court. Usually if your backyard is the place then no permission is required.

A standard tennis court is 120ft by 60ft, but for general purpose court 110ft by 55ft will the do the job quite adequately. Not only this, it can save a fortune which can be used in building a store house.

Fencing around the back of the tennis court can be visually less intrusive.

The thickness of the clay tennis court can impact the speed and bounce of the ball. A thicker court will mean the ball will speed away after hitting the ground. Similarly a softer court will slow down the speed but for the very same reason the ball bounces higher and a player gets more time to take his or her shot.

As discussed earlier drainage can take a severe toll on your budget if not planned properly. The elevation of the court if same as the surrounding area will assist a lot in surface level drainage system.

For a natural clay court, the basic rule goes like 8 inches of cinders, then 1.5 inches of grave, 3 inches of clay and on top around 1 inch of surface mixture. Color of the surface is very important in reducing the glare of the sun.

The aesthetics of the court should be given extreme care. For a great range of color and textures there are varieties of materials available today. Not only texture, they also come in various grades from very fine to coarse materials. These can play important role to control from the amount of slide to the speed of play. The depth of granules over the surface can be cleverly adjusted to control the degree of slide on a synthetic clay court.

Dusting the tennis court with chloride of calcium helps to bind the surface material and make the courts wear better.

Even after every care been taken there can be chances that after first rain small depressions start to appear. These should be marked and gradually brought to grade by light top dressing of the clay surface mixing.

Finally, a court set open on the landscape can be somewhat of an eyesore. Plant some trees at a distance so that broken shadows dont fall on the court. Also borders of low shrubs around the court can harmonize the same with a natural look.

How Caulks And Sealants Are Used In The Modern-day Construction Industry

Posted on by blogger

A trip to your local home improvement store can be an overwhelming experience for the average person, especially if you’re trying to figure out which caulks and sealants to use for your exterior home improvement project. Unlike the interior, the exterior faces high UV exposure, extreme temperatures and the requirement to stay 100% waterproof.

When you’re dealing with silicone caulks, you have a non-paintable surface, with poor UV performance. Although water based and latex caulks have good paintability, they also have high shrinkage, poor elasticity and poor UV performance. Synthetic-rubber (polyurethane) sealants and tri-polymer sealants (silyl terminated polyether sealants) can do it all: paintable, great moisture sealing, no or low shrinkage, and very good UV resistance. Many are also pre-tinted in popular colors. These include the popular NP1 (polyurethane sealant), Sonolastic 150 VLM, and Novalink sealants.

All of these sealant and caulk materials are heavily advertised and marketed with super flashy packaging, labels and all kinds of fancy logos. If you’re looking for a high performance caulk or high performance sealant, you can literally be confronted with hundreds of brands and companies that claim to have the best product for your needs. So what can you do, when you are bombarded with all kinds of choices?

Each brand of caulk generally has its own special and unique qualities. Although, it is in your best interest to read all of the labels and also follow the company specifications, for the use of the caulk and sealant, the very thing you want to know may not be found on the labels of the containers at all! Many of the best products are architectural / commercial grade and not generally available to the public.

Sealant was originated through the needs for exterior finishing in the home building industry. Caulk was originally a term that was used to describe the sealant material used to build boats. Many companies and manufacturers these days are using caulk as an all-purpose word to describe paintable interior grade products. Sealants by definition have at least /-25% elongation capability over a long-term period and are UV resistant. Advanced sealants are 100% solids and offer up to 100% elongation.

Most of the general public use caulk and sealant interchangeably to serve the same basic purpose, which is to fill gaps between building materials and to shield materials from air and water.

Although sealants and caulk work the same basic manner, they both also fail for the same basic reasons. There are three major types of caulk failures that you will encounter. These are substrate, cohesive, and adhesive. The bond that is put between the substrate and the caulk can actually fail, making the caulk tear and break down. Caulked joint problems are also very common and are usually due to the substrate not being effectively prepared or using the wrong product all together.

So, before you choose a certain kind of product, you want to really think about how you will be using it and for what purpose. You will also want to consider the area or location you are going to apply the caulk or sealant.

For example, if your intent is to seal the area around the base of a toilet, sink, bathtub or shower, it will be imperative that you purchase a product that both mildew-resistant and durable enough to survive scrubbing and chemical cleaning. If your intent is going to be to use sealant or caulk between wood clapboards and vinyl windows, then you’ll need to purchase a product that is able to bond very well to both types of materials and is weather resistant.

You will also want to keep humidity, temperature and moisture in mind when you are shopping for caulk or sealant. Water-based caulks not recommended for outdoor projects, because these products do not withstand the hot-to-cold and cold-to-hot weather changes, as well as other harsh weather situations. If you are living in an area that is below 50F during the time you need to apply sealant, then you’ll probably want to use a silicone sealant, instead of polyurethanes, because polyurethanes are very difficult to apply in chilly conditions.

Other Applications: For sealing skylights, glass domes, greenhouses and such, Sonolastic Clear 25 is a popular product. For Kynar or siliconized paint finished metal roofs, a special sealant formulated to seal to these surfaces is a must. Products such as Duralink are popular. For repair of swimming pool tile grout lines, polyurethane sealants are excellent. Products like Ultra provide a very durable seal, which can survive in areas where grouts fail quickly. Ultra is also used as a pickproof sealant in security applications.

To the delight of many, who prefer the do-it-yourself project, certain caulks and sealants can be color-matched to paints, tiles, grout, wallpaper and even carpeting. The beauty of these products is that they can be color-matched while they are still in the product tube. NP1 is also available in many popular pre-formulated colors. Any good home building products store will be able to help you color-match your caulk and sealant to your desired color. Once the caulk has cured, then it will precisely match the color you were seeking to acquire.

In summary, let’s review your options again:

1. Water-based caulks are the easiest to work with. They have a smooth, thin and consistent flow, and they are easy to apply with almost any tool. These products cure quickly, have very little odor, and the clean up is easy with water.

2. Silicone caulks and sealants are good for interior or exterior areas, which will not be painted and are good for areas that will be exposed to extremely cold weather, certain metals, and glass. Silicone materials do not repair well (nothing wants to stick to cured silicone material, not even more silicone)

3. Synthetic rubber sealant is best used for areas with high movement and dissimilar materials. These materials can be painted and are designed for long-term exterior exposure. There is also less chance that the synthetic rubber bond will break during movement. Common applications are roof tile repairs, roof moldings, and roof to wall sealing, window frame sealants, and doorsill sealant.

4. Self Leveling Expansion Joint Sealant, such as SL1 and SL2, are used to fill and seal the expansion joint gaps in concrete and driveways.

5. Tri-Polyimer sealants, such as Sonolastic 150VLM are the next generation. Although somewhat more expensive, they offer superior exterior performance.

6. New Hybrid products are available that defy all classifications. Using these kinds of sealants can yield a lot of surprises, so be sure to read the instructions carefully. Some of these products tend to expand upon drying, so it is best to test them out in an inconspicuous location before actually using them on your project.

Print this article and take it with you when you are shopping for caulk and sealant. Review it and then follow any instructions on the containers of the products you buy. It is our hope that this quick tutorial will help provide some clarity on exactly what products you should buy for your home improvement or home construction project.

the delays in construction assignments

Posted on by blogger

excepted delay in Building projects/p>

No less than 60 percentage with the task delay are simply because on the method of taking care of the other forty per cent. The delays beginning using a change order demand, and further delays arises because of the technique of managing the original delays. 59 pct of task delays could possibly be prevented by having an useful project administration program.

During my work within the construction projects for that previous 5yrs, I noticed that greater than 80 percent of my corporation jobs are postponed. The main reason on the delays is varied coming from a task to a different task, however, there is a shared component in all the project and that isthe means of managing the original delays.

I will explain beneath the leading reasons in the construction projects delays , their effect on the project and also the probability to prevent the delays a result of each cause. I split the reason why in the delays in to a pair of primary variables

1- DELAYS On account of EXTERNAL FACTORS:

External factors are those occasions of delays which are not connected on the builder and never under his control, they happened from the customer or the expert, and impact the development on the perform or break the normal series on the activities. The exterior aspects are typically modify requests and successor activity, i think, they present 40 % from the building project delays reasons.

A. Modification requests:

Change orders or variation orders is among the most well known issue influencing the work progress, and also this commonly issued for the contractor through the customer or even the project consultant. Change orders occurred on account of designing inadequacies or because of customer requirement.

B. Successor tasks:

In case the contractor works linked with others tasks complete to commence, this could be an excellent basis for building delays. A case in point of complete to begin connection, one company is answerable to the project structure (groundwork and concrete), and another builder is responsible for the finishes works. This factor can’t be handled, but needs to be clearly identified in the company supervision plan to notify your client that in case X activity delayed by builder 1, Y activity will likely be delayed by builder 2.

2- DELAYS As a result of Inside Variables:

Interior Aspects are completely within the contractor control and liability, any delays takes place for the task on account of those Aspects, the contractor will carry all of the implications. Sad to say 60 percent from the task delays are caused by interior factors for instance poor management and insufficient man power and equipment.

A. Poor operations:

Insufficient a good project management programme and bad Building Project Preparing is usually a typical cause with the project waiting times . It really is easy with the contractors to get ready a period of time schedule, However, to develop a full project management software plan and adhere to it, here is the actual concern. Below is really a listing of the missing elements from the normal project managing strategy for just a building project.

B.Lack of labor and equipment:

Labor and tools will be the sources to carry out any task, any insufficient these resources will straight lead to a delays. The productivity is also involved with the numbers, reduced efficiency will defiantly result in project delays. The subsequent causes will explain the reasons you can have insufficient effort and tools in a construction project.

Underestimation on the activity complication.

Lower productivity charges.

No available resources inside regional market.

Task management technology is important now. If you want to deal with any project you ought to be mindful of the planning approaches and regulations. You may check the Planning Engineer website for no cost lessons and more project management products. http://www.planningengineer.net

Negligence To Blame For International Construction Accident

Posted on by blogger

In a continued showing of gross negligence in international construction, official reports from India this week announced that cost cutting measures circumvented many construction standards and safety protocols in order to cut construction costs. The same construction site under the supervision of the Delhi Metro Rail Corporation (DMRC) that experienced the worst accident in its history on July 12 suffered another setback to rescue operations when the rescue cranes collapsed, injuring 5 workers.

The official report, announced by Saugata Roy, minister of state in India’s Ministry of Urban Development, revealed that in order to save money on the project, the construction company contracted to perform the work was also given the task of designing parts of the bridge. This presents not only a conflict of skills, but a conflict of interest; the construction company has it in their best interest to save as much money as possible on materials and construction. The construction company in question, Gammon India Ltd, maintains that costs were not cut and that all safety standards were followed to the letter. The question of the legitimacy of this claim is up for debate, however. During the first phase of construction for the Delhi Metro, the design was performed by Delhi Metro Rail Corporation and its consultants while construction was carried out by separate contractors. However, during the second phase the duties of construction and design were combined, creating a possibility for a serious construction site accident.

The initial construction site accident occurred on July 12, when a section of railbed bridge collapsed, killing 6 total workers and injuring approximately 15. This accident followed the October 2008 construction accident in which a crane placing concrete slabs collapsed killing two and injuring 30 others. Opinions differ on the true cause of these construction accidents; negligence and cost cutting measures have been officially announced, though there are some who say that these factors are part of a larger problem of rushing the work in the first place. In anticipation of the the 2010 Commonwealth Games, scheduled to be held in New Delhi beginning October 3rd, 2010, the government is pushing the metro project with haste. This will be the largest multi-sport event conducted to date in Delhi and India, and the municipal government wants to present a modern transit system to the world’s visitors as they arrive and travel throughout the city.

However, despite all the pressure and money funneled into the project, progress is not being made as fast as the city would like. With setbacks such as these fatal construction accidents and the looming possibility of several construction accident lawsuits, completion of construction is on a tight time line. It is almost certain that there will be legal action against Gammon India Ltd., as family members have likely contacted a construction accident lawyer. Indeed, Gammon India Ltd. been involved in legal proceedings in the past, though it is unclear what the future holds for the company.

Renting Construction Equipment Will Save Project Cost

Posted on by blogger

When you are renting out construction equipment, you are saving on the cost of your project. Construction equipment rentals have helped to save costs on many construction projects. Not every construction company owners would like to purchase such equipment because it would not fit their budget. Also the utility of such equipment would be less as per the whole project. Each of such equipment would cost a lot but there use would be only limited from project to project. Therefore it makes no sense to buy such equipment and keep for such a high price for a single purpose alone. This is why it is better to rent such equipment out and control the cost of the project.

There can be different vehicles required for construction. These can include mixers, excavators, industrial loaders, boom lifts, rollers etc. Purchasing all such equipment can quite often cost a fortune for the company. Therefore it is necessary for companies to rent such equipment out. This will help save the company money time and labor.

There are many other cost benefits that can be associated with renting out construction equipment. Breakdown costs are totally eliminated. If there is any fault in the machine then it is taken care of by the rental company. It is the duty of the rental company to provide fault free equipment that will help to complete the construction on time. If there are any breakdowns then they will be attended to and repaired by the rental company. Similarly all the maintenance cost of the equipment is taken care of by the rental company.

The construction company would only rent these vehicles to use them. However, the maintenance and the service of these vehicles would be taken care of by the rental company. Now if the construction company had purchased these vehicles then they would have had to take care of their maintenance as well which is again a lump sum amount at intervals of time. This cost is now being completely eliminated.

Storage of the vehicles will also be a big problem. If you have purchased such vehicles, you would also have to think of their storage facility. You cannot just store them in a garage. This equipment is quite bulky and most of the times you need to store them in a special manner. This is taken care of by the rental company. You dont have to go looking for special places to store these vehicles.

There is no capital investment involved in the. The equipment is rented out on a contract basis. The money that is saved by this can be effectively used in other areas. Also this increases the borrowing power of the construction company. The equipment that is rented out will not appear as a liability. It on the other hand increases the asset to liability ratio in favor of the construction company.

With so many benefits at hand, it is obvious why more and more construction companies are now going for renting out construction equipment rather than purchasing them.
