Many general contractors are not too familiar with technical trade work and must rely on experts. A water line added or a new electrical circuit requires more than meets the eye to accomplish the installation of the item. Experienced MEP – Mechanical, Electrical and Plumbing tradesmen are experts with apprentice programs often totaling 8 years or 16,000 hours of work to become a master journeyman. These MEP experts should be relied upon for their respective systems that can cause many ongoing problems in a home or business. The MEP tradesman’s work if improperly designed or incorrectly installed can result in sewer gas, explosions, gas leaks, water leaks, flooding, excessive humidity issues, carbon monoxide poisoning, fire and electrocution. Because of this risk to the structure and the inhabitants of a building we have building codes.
Skipping the building permit or MEP permit is never a good choice. The truly professional contractor always plays by the rules as the permit and inspection process allows for peer review of the work and ensures that local jurisdictions are satisfied. The process often slows the job down and tends to delay construction but it is also a safety net used by general contractors to ensure that building is progressing according to code.
Many general contractors must rely on specialty mechanical contractors, electricians, and plumbers for their estimates and work skills. In some states contractors must test and have a working knowledge of all trade areas, best construction practices and common code issues encountered to get a contractors license. Other states may only require a fee to obtain licenses along with a vernal liability insurance policy. In spite of the local licensing requirements or if knowledge based testing is required a smart general contractor is a generalist. The generalist is like the family Practitioner who treats common colds and looks for signs or disease and other systemic problems. He doesn’t fix many problems but refers you to a specialist i.e., heart doctor or an orthopedic surgeon. So to must the contractor be able to manage tradesman properly, framing spacing, shingle layouts, plumb door, etc….
In the insurance world of restoration work- restoration contractors deal with the same issues of safety and temper utilities during mitigation and need professional help. During the construction phases skilled trades are vital to the project. In the insurance world MEP estimates requiring knowledge of these trades are often left “open” or “undetermined”. Many contractors stated that they are waiting for a license electrical, plumber or HVAC company to assess the job before preparing the estimate. Why because general contractors and restoration contractors are either not knowledgeable of these trades, the codes and the specific design requirements of the systems.
