NIH Master Electronic As-Built Drawing LOP

This NIH As-Built Drawing local operating procedure contains the steps that a contractor must perform when adding to or editing the master electronic drawings for the NIEHS facility located in Research Triangle Park, NC as a part of a project. A contractor must make these changes when a project affects architectural, mechanical, electrical, etc. aspects of the NIEHS facility so that the drawings stay up-to-date and changes from various projects are incorporated into a single master electronic drawing.

Step 1: Request Current Drawings- This step is appropriate when the contractor has made substantial progress in the project and is ready to integrate the project changes with the master electronic drawings. The master electronic files should be requested after the project as-built drawings are accepted by the PO. The contractor is to contact the Project Officer (PO) for the drawings. The contractor must specify which Building/Module/Floor location(s) they require for the changes and which project number/description the modifications are for. The contractor may not use drawings provided for design for this purpose, as the file has likely been updated.

Step 2: Receive Current Drawings-

The PO will reply to a request for current electronic drawings by emailing the files to the contractor. These electronic files have been standardized so that the number and property of AutoCAD layer names, layer colors, linetypes, and layer descriptions remain constant (Table 1). Once the PO sends a contractor a file, no other contractors will have access to that file until the modifications are complete and determined to be accurate.

Step 3: Make Modifications to Drawings-

The contractor can now edit the drawings to integrate the project changes. The contractor may only use the existing layers and may not delete any layers from the drawings. If a contractor has a question regarding which layer to put an item on, they must contact the PO. The contractor may not make any changes unrelated to the project specified in the request. The contactor may not use referenced files (xrefs).

Step 4: Send Drawings to Project Officer-

The contractor can now send the electronic drawings to the PO through email (or CD based on PO’s preference). The contractor should include which Building/Module/Floor location(s) they are attaching and the project number/description the files are for.

Step 5: Project Officer Will Review Drawings-

The PO will now review the drawings for accuracy. The PO will reject the files if they find any errors, omissions, or standardization changes. The contractor will then need to address or make changes for any inaccuracies.

Step 6: Project Officer Will Accept Drawings- The PO will notify the contractor once the electronic submissions are acceptable.
