Even the simplest electrical system can become dangerous. Unless proper procedures are instituted, personnel installing or servicing these systems are frequently exposed to the hazards of shock, arc flash and arc blast. Eliminating and/or reducing these hazards require a basic knowledge of electric circuits. The following is a brief overview.

National Electrical Installation Standards™ are designed to improve communication among specifiers, purchasers, and suppliers of electrical construction services. They define a minimum baseline of quality and workmanship for installing electrical products and systems. NEIS® are intended to be referenced in contract documents for electrical

Electrical estimating is fast becoming a profession, performed by professional people. Contractors can no longer look at a job and "guesstimate" a price, or for that matter, even "square-foot" the job. If an electrical contractor is to survive in today's competitive

Any indication of system deficiencies whether discovered as a result of the Owner's or Contractor's checks and tests, shall be brought to the immediate attention of the Quality Control Manager so the system can be modified to correct these deficiencies. This Project Quality Plan shall be refined and modified as required to support Overall

Before covering any plumbing with hardscape or concrete, cap all spray lines and pressure test the system. It is recommended the system be pressurized between 20psi and 25psi for a minimum of 2 hours. Maintain a pressurized system during the concrete phase of construction to be sure no damage is done to the pipes.

source of a separately derived system, or to the equipment grounding conductor at each building or structure disconnect that is supplied by a feeder. As pointed out above, a Ufer ground refers to an electrical system ground which utilizes the reinforcing steel rebar(s) in a concrete foundation as the grounding electrode.

Cement companies face a major challenge in emerging markets where bulk and bags coexist. To gain competitive advantage, these cement companies have to build two different supply chain strategies, one for each type of product. The bulk cement supply chain has to be focused on efficiency to obtain benefits from optimization

Batch plants are provided on projects where it is more economical to produce concrete on site than to buy a ready mix. Aggregate storage piles, cement silos and admixture tanks will accompany an on-site batch plant. Shops are used where materials and equipment are fabricated on site. This includes electrical, mechanical, carpentry, and paint shops.

required for electrical generation from geothermal energy in stable continental areas of moderate to low heat flow. Because it is not economically feasible to drill this deep for electrical power generation, exploration for geothermal energy focuses on areas where higher than normal heat flow is expected. provide a generalized review of

Line Diagrams A line (ladder) diagram is a diagram that shows the logic of an electrical circuit or system using standard symbols. A line diagram is used to show the relationship between circuits and their components but not the actual location of the components. Line diagrams provide a fast, easy understanding of the connections and

MEP systems must satisfy multiple objectives and criteria for design, installation, commissioning, operation, and maintenance. Different types of specialty contractors (e-g., process piping, HVAC piping, WAC ductwork, plumbing, electrical, fire protection, controls) are responsible for these systems.

Concrete is an ideal medium for recycling waste or industrial byproducts. Many materials that would end up in landfills can be used instead to make concrete. ! Concrete is modest in its energy needs and generous in its payback. The only energy intensive demand is in the manufacture of portland cement, typically a 10-15% component of concrete. !
