AS-BUILT DRAWINGS
Upon completion of a facility, the crew
leader or project supervisor should provide
operations with marked prints that indicate
any construction deviations. The information
required must show all features of the
project as actually built. It is necessary for
operations to review the as-built drawings
after they are completed. This assures that
all information appearing on the drawings
shows the exact as-built conditions.
From the as-built drawings, record
drawings are prepared. These drawings are
the original construction drawings but are
corrected according to the as-built marked
print. They then provide a permanent record
of as-built conditions. The original record
drawings must be kept up-to-date at all
times. If maintenance requires a change to
the record drawing, this information should
be passed back to operations or to the
maintenance control division so the record
print can be updated.
SCHEDULES
The schedule is a systematic method of
presenting notes and information in tabular
form. This makes the detailed information
required easily accessible to the Utilitiesman
and specifications writer. Schedules are used
mostly on large projects.
A plumbing fixture schedule lists the
type of fixture and identifies each one on the
drawing by number. The manufacturer and
catalog number of each type of plumbing
fixture are provided along with the number,
size, and type of fixture. A column is left for
additional remarks. This Remarks column
may provide such information as the
mounting height above the finish floor (for
wall mountings) or any other information
required for proper installation. Sometimes
this same information can be found in the
specifications of the project, but combing through
page after page of written material can be time
consuming. You may not always have access to
the specifications while working, but the drawings
are there. Therefore, the schedule is an excellent
way of providing essential information in a clear
and accurate manner, allowing you to carry out
your task in the least amount of time.
SPECIFICATIONS
When project specifications are prepared, they
must be brief, clear, and complete. Specifications
must convey the complete description of the work
to be performed in a clear, concise, and coherent
manner, stating the actual minimum needs of the
government and the conditions known, such as site
location or special construction techniques. The
use of general statements should be avoided.
The specifications should be used with
construction drawings to provide the Utilitiesman
the needed details of a project. The drawings
show the extent, size, shape, generic types of
material, and the relationship between different
materials. The specifications should describe the
quality of materials, the installation requirements,
and the method of construction. The writer of
specifications should review the drawings during
and after the writing of specifications. The
ensures that the information appearing on the
drawings has been covered in the specification and
that all the requirements to accomplish the work
have either been covered in detail on the drawings
or described in the specifications. On the other
hand, the designer or engineer should review the
specifications to ensure complete coordination.
Quite often, a simple detail, section, or note on the
drawings makes it possible to eliminate lengthy,
descriptive statements from the specification and
at the same time clarify the designer’s intent.
Conflicts or duplications between drawings and
specifications must be eliminated. The terminology
used in specifications and drawings must be
identical.
