documents?
Answer: A list of the contract documents is contained in General Clauses and Conditions. A
listing of the Commercial Building contract documents is presented in this chapter under the
heading “Commercial Building Plans.” The instructor may wish to have the students check over
this listing and compare it with the plans provided.
2. The requirement for temporary light and power at the job site will be found in what
portion of a commercial building’s specification?
Answer: The Supplementary General Conditions specifies the job site requirements for
temporary light and power. In some contracts, this electrical system becomes the responsibility
of the general contractor; in other contracts, it is the electrical contractor’s responsibility to
install and maintain the temporary electrical system. The instructor may wish to refer the student
to NEC Article 590 and discuss the requirements in detail.
