FIGURE 17.5 Analysis of subcontractor bids.
In a complicated trade, such as Moisture Protection, shown in Fig. 17.5, it is
necessary to tabulate, from answers obtained by questioning each of the bidders,
the exact items that are included and excluded. In this way, an evaluation can
intelligently be made, not only of the prices submitted but also as to whether or
not the subcontractors are offering a complete job for the section of work being
solicited. Where an indication in the subcontractor’s proposal as in Fig. 17.5 shows
that a portion of the work is being omitted, it is necessary to cross-check the
specifications and other trades to be purchased to ascertain that the missing items
are covered by other subcontractors.
Subcontract Forms. Various subcontract forms are available for the written agreements.
A commonly used form is the standard form of agreement between contractor
and subcontractor (Contractor-Subcontractor Agreement, A401, American
Institute of Architects). A short form of subcontract with all the information appearing
on two sides of one sheet is shown in Fig. 17.6a and b. Changes may be
made on the back of the printed form with the permission of both parties to the
agreement.
Important, and not to be neglected, is a subcontract rider (Fig. 17.7), which is
tailored for each job. Only one page of the rider is shown in Fig. 17.7. The rider
takes into account modifications required to adapt the standard form to the specific
project. The rider, dealing with such matters as options, alternatives, completion
dates, insurance requirements, and special requirements of the owner or lending
agency, should be attached to all copies of the subcontract and initialed by both
parties.
One additional clause that should appear in all subcontracts is the following:
