d. Preparation of plans and specifications. The next
step in the repair or rehabilitation process is preparation
of project plans and specifications. When required by a
major rehabilitation project, a Concrete Materials Design
Memorandum, in the form of a separate report or a part
of the Rehabilitation Evaluation report, should be prepared
as outlined in Chapter 9. Existing guide specifications
should be used to the maximum extent possible. However,
many of the materials and methods described in this
manual are not covered in the existing guide specifications.
If the materials and methods needed for a particular
repair project are not covered in the guide
specifications, a detailed specification based upon the
guidance given in this manual and upon experience gained
from similar projects should be prepared. Since the full
extent of concrete damage may not be completely known
until concrete removal begins, plans and specifications for
repair projects should be prepared with as much flexibility
with regard to material quantities as possible. A thorough
condition survey, as outlined in Chapter 2, performed as
close as possible to the time repair work is executed
should help minimize errors in estimated quantities.
