Patients in hospitals, outpatient facilities and nursing homes require special protection from the elements of a fire, of which smoke is one of the most dangerous. In fact, smoke control is especially critical in these facilities.
Commissioning is not primarily a process of error identification. It is a quality-assurance program-undertaken while the workforce is still on the site and before the damage is done. When the commissioning process begins in the planning and design phase, it can be the ounce of prevention that eliminates the pound of cure required in the final project stages.
When executing the design of a security system, the bid award and contractor selection may be the most important part of the project. While it sounds like an easy task, choosing the wrong contractor for the desired security systems can be a nightmare.
Commissioning and acceptance testing demonstrate that the final integrated system complies with the design and that any modifications were correctly and successfully incorporated, so that the result is a properly functioning system. The design engineer must be involved with the test-and-balance contractor, the mechanical contractor, electrical contractor, controls vendor and fire-alarm vendor.
