Electrical contractor

Bids received can vary by up to 100 per cent over a range of hrms. The higher bids may be from hrms who do not want the job but wish to keep contact with the client. Where there is a difference of more than 10 per cent between the lowest and second-lowest bidder, this can cause problems. For example, the Electrical Contractors Association offer a guarantee of completing through their members, at no extra cost, in the event that a member is unable to do so, but only if the difference between the contractors appointed and the next bid is not more than 10 per cent. In some instances, this could be enough to seriously consider not accepting the lowest bid. 

The installer engaged by the furniture supplier did a truly professional job. It was finished sooner than expected. There was some fear that the monolithic countertop slabs, which were pre-fabri-cated at the factory, might have size discrepancies. They did not, due to very careful measurements taken when the order was placed. The plumbing contractor chosen by the engineering firm did excellent work. The electrical contractor was pleased with the way circuits had been planned, and the planner in turn was highly satisfied with his installation. At the laboratory operator s request, all information regarding installation and maintenance was saved and later filed. The contractors admitted that this was not their common practice, but they were all in favor of it. 

The detailed-t eoff method can rarely if ever be used. When detailed drawings are available, costs may be estimated by pricing materials and components from suppliers catalogs or, for special items, from quotations. Handbooks are available which give typical values of the labor-hours required to perform units of installation work, such as installation of switches, starters, motors, conduit wiring, and push buttons of various sizes, for both hazardous and nonhaz-ardous areas. Labor rates can be obtained from various government statistical sources or elsewhere. For the United States the National Electrical Contractors Association publishes an excellent manual of electrical costs. From the complete plans and specifications, the estimator can take off materials, estimate the labor cost, apply appropriate factors for labor efficiency, productivity, and local conditions, and achieve good results. 

There are two large electrical contractors well qualified to handle the job. Neither has instrument installers but both have connections, and have worked with well-reputed national firms specialized in instrumentation and would use them as subcontractors. 

Electrical / Instrumentation. Include both electrical contractors. 

Electrical Rough- Work performed by the Electrical Contractor after the plumber and heating contractor are complete with their phase of work. Normally all electrical wires, and outlet, switch, and fixture boxes are installed (before insulation). 

Electrical Trim- Work performed by the electrical contractor when the house is nearing completion. The electrician installs all plugs, switches, light fixtures, smoke detectors, appliance "pig tails", bath ventilation fans, wires the furnace, and "makes up" the electric house panel. The electrician does all work necessary to get the home ready for and to pass the municipal electrical final inspection... 

Electrocutions kill an average of 143 construction workers each year. Data from 1992 through 2003 indicates electrical workers suffered the highest number of electrocutions per year, 34 percent of the total deaths caused by electrocution ( Alarming statistics, by D. Bremer, 2007, Electrical Contractor). Direct death from electrical shock results from ventricular fibrillation, paralysis of the respiratory center, or a combination of the two. Electricity can be hazardous to the process employees in a variety of forms. They are ... 

An electrical contractor is a part of the construction team, usually as a subcontractor, and therefore the regulations particularly aimed at the construction industry also influence the daily work procedures and environment of an electrician. The most important recent piece of legislation is the Construction Regulations. 

There is a lot of work for electrical contractors in my part of the country, updating and improving the lighting in government buildings and schools. 

Finally, it should perhaps be said that a foolproof method of giving protection to people or animals who simultaneously touch both live and neutral has yet to be devised. The ultimate safety of an installation depends upon the skill and experience of the electrical contractor and the good sense of the user. 

The brackets are usually made from flat iron, which is painted after manufacturing to prevent corrosion. They may be made on-site by the electrician or, if many brackets are required, the electrical contractor may make a working sketch with dimensions and have the items manufactured by a blacksmith or metal fabricator. 

The electrical contractor is charged with a responsibility to carry out a number of tests on an electrical installation and electrical equipment. The individual tests are dealt with in Part 6 of the lET Regulations and described later in this chapter. 

The electrical contractor is required by the lET Regulations to test all new installations and major extensions during erection and upon completion before being put into service. The contractor may also be called upon to test installations and equipment in order to identify and remove faults. These requirements imply the use of appropriate test instruments, and in order to take accurate readings consideration should be given to the following points ... 

Electrical contractors install equipment and systems in new buildings. Once a building is fully operational, the electrical contractor may provide a maintenance service to that client or customer or alternatively the client may employ an in-house electrician to maintain the installed electrical equipment. It all depends on the amount of work to be done and the complexity of the customers systems. 

Customers employing an electrical contractor who has ECA membership are guaranteed that the work undertaken will meet all relevant regulations. If the work undertaken fails to meet the relevant standards, the ECA will arrange for the work to be rectified at no cost to the customer... 

It is a common practice to ask a number of electrical contractors to tender or submit a price for work specified by the bill of quantities. A tender is a formal offer to supply goods or carry out work at a stated price. The contractor must cost all the materials, assess the labour cost required to install the materials and add on profit and overhead costs in order to arrive at a final estimate for the work. This will be the tender price. The contractor tendering the lowest cost is usually, but not always, awarded the contract. 

To complete the contract in the specified time the electrical contractor must use the management skills required by any business to ensure that men and materials are on site as and when they are required. If alterations or modifications are made to the electrical installation as the work proceeds which are outside the original specification, then a variation order must be issued so that the electrical contractor can be paid for the additional work. 

The supplementary agreement - this allows the electrical contractor to recoup any value-added tax paid on materials at interim periods. 

In signing the contract, the electrical contractor has agreed to carry out the work to the appropriate standards in the time stated and for the agreed cost. The other party, say, the main building contractor, is agreeing to pay the price stated for that work upon completion of the installation. 

The contractor - the main contractor takes on the responsibility of the whole project for the client. The main contractor may take on a subcontractor to carry out some part of the whole project. On a large construction site the electrical contractor is usually the subcontractor. 

Handing over the completed electrical installation to the client is a big day. The job is finished and the electrical contractor can now be paid in total for the work done. You are effectively saying to the client here are your electrical circuits, systems and equipment just as you ordered, let me show you how everything works . You should then ... 

An electrical contractor is responsible for the installation of electrical equipment within a building. An electrical contracting firm is made up of a group of individuals with varying duties and responsibilities (see Fig. 2.1). There is often no clear distinction between the duties of the individuals, and the responsibilities carried by an employee will vary from one employer to another employer. If the firm is to be successful, the individuals must work together to meet the requirements of their customers. Good customer relationships are important for the success of the firm and the continuing employment of the employee.
