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.
