Chapter hvac engineering Fundamentals: Part 1 Introduction

13.5
Summary
Valid contracts require a scope of work, a time of delivery, and a com-
pensation for service. The best system designs will be unsatisfactory
if they are not communicated properly to the contractor through the
design documents, drawings, and specifications.
Document preparation is both an art and a science, but it can and
must be mastered by HVAC system designers. The drawings and spec-
ifications complement each other, complete the design, and are part of
the legally binding commitment of the contractor or vendor to the
owner. Consistent drawing and specification formats and style help
make a clear, concise directive to the contractor for required work.
