The revisions from Contractor Markups and field inspection notes are transferred to the Final as-built set of drawings. The final as-built drawings include modifications during construction, field requested changes, shop drawing modifications, and contractor designs, B. DESCRIPTION OF WORK

Section includes: Administrative and procedural requirements for as-built process for contractor to follow.

C. RECORD DOCUMENT SUBMITTALS

Record As-Built Drawings: General Contractor shall maintain on-site 2 sets of as-built Contract Drawings, in Contractor Field Office. Working as-built drawings shall be kept current on a weekly basis and at least one paper set of as-built drawings shall be available on the jobsite at all times.

Note that MEPCE will not provide plumbing CAD files to the Contractor.

1. Changes to material or equipment for substitutions approved through the

Architect/Engineer’s submittal process.

2. Where contract drawings or specifications show options or alternates, only the option selected for construction shall be shown on the final as-built prints. Cross out such words and phrases as “approved equal” and list specifically the material provided. This shall include actual make and model number of equipment installed, as well as voltage and MCA.

D. MARK-UP GUIDELINE

22 0500 - 4 COMMON WORK RESULTS FOR PLUMBING

The following information is provided to improve the quality of the marked-up prints and thereby facilitate preparation of final as-built drawings. The most important guideline is that the marked-up changes on the prints shall be complete and understandable.

1. Frequently use written explanation on As-Built drawings to describe changes. Do not rely totally on graphic means to convey the revision.

2. Legibility of lettering and digit values shall be clean and clear and readable from a scanned copy.

3. Whenever a revision is made, make changes to affect related section views, details, legend, plans and elevation view, schedules, notes and call-out designations, and mark accordingly to avoid conflicting data on all other sheets.

4. When changes are required on small-scale drawings or on drawings with limited area available, large-scale inserts shall be drawn or sketched, with leaders to the location where applicable.

5. When attached prints (or sketches) are provided with marked-up print, indicate whether:

a. Entire drawing shall be added to contract drawings or

b. Whether the contract drawings shall be changed to agree, or

c. For reference only to further details not required for initial design.

6. Make the comments on the drawing complete without reference to letters, memo’s or materials that are not also a part of the As-Built. For instance, do not just say, “As per Change Order #12”, when the actual change order states, “Changed water pipe from 2-1/2” to 3”. This also applies for changes as per the Architect/Engineer, Owner or Inspector.
