SECTION 01720 AS-BUILT DOCUMENTS
PART 1 - GENERAL
A. CONTRACTOR shall maintain and provide the ENGINEER with record documents
as specified below, except where otherwise specified.
B. Maintenance of Documents:
1. Maintain in CONTRACTOR'S field office in clean, dry, legible condition complete
sets of the following: Drawings, Specifications, Addenda, approved Shop
Drawings, Samples, photographs, Change Orders, other modifications of
Contract Documents, test records, survey data, Field Orders, and all other
documents pertinent to CONTRACTOR'S Work.
2. Provide files and racks for proper storage and easy access. File in accordance
with filing format of Construction Specification Institute (CSI), unless otherwise
approved by ENGINEER.
3. Make documents available at all times for inspection by ENGINEER and
OWNER.
4. As-built documents shall not be used for any other purpose and shall not be
removed from the CONTRACTOR'S office without ENGINEER'S approval.
C. Marking System: Provide colored pencils or felt tipped pens for marking changes,
revisions, additions and deletions, to the record set of Drawings. Use following color
code unless otherwise approved by the ENGINEER:
1. Process and Mechanical: Red
2. Other Printed Notations: Black
D. Recording:
1. Label each document "PROJECT AS-BUILTS" in 2-inch high printed letters.
2. Keep record documents current.
3. Do not permanently conceal any Work until required information has been
recorded.
4. Drawings: Mark-up actual installations, which vary substantially from the work as
originally shown. Mark whichever drawing is most capable of showing the as-built
condition fully and accurately; however, where shop drawings are used for mark-
up, record a cross-reference at the corresponding location on the contract
drawings. Mark-up new information, which is recognized to be of importance to
the OWNER, but was not shown on either the contract drawings or shop
drawings. Give particular attention to concealed work, which would be difficult to
measure and record at a later date. Note related change order numbers where
applicable. Organize as-built drawing sheets into manageable sets, bind with
durable paper cover sheets, and print suitable titles, date and other identification
of the cover of each set. The following minimum information shall be included, as
applicable:
a. Depths of various elements of foundation in relation to datum.
b. Horizontal and vertical location of underground utilities and appurtenances
referenced to permanent surface improvements.
c. Location of internal utilities and appurtenances Concealed in construction
referenced to visible and accessible features of structure.

d. Field changes of dimensions and details.
e. Changes made by Change Order or Field Order.
f. Details not on original Drawings.
g. information to be shown for potable water mains, reuse water mains, and
sanitary force mains shall include the location of valves, tees, bends and
crosses dimensioned to the baseline survey or monument, including the
station and offset. Elevations at top of pipe shall be provided every 50' and at
locations where design elevations were shown on the plans. For situations
where the pipeline is being adjusted to avoid conflicts with other utilities (less
than 50' in total length), then elevations shall be provided at the beginning of
the deflection (i.e. the first bend), middle of the deflection (i.e. the point where
the conflict would have occurred with the utility), and the end of the deflection
(i.e. the last bend).
h. Information to be shown for gravity sanitary sewer mains shall include invert
elevations at manholes.
i. information regarding all trenchless technologies horizontal and vertical
location including bore/jacking, micro tunneling, and directional drilling. All as-
built drawings shall show the geometry, horizontal, and vertical location of the
directional drill path including the starting point, end point, and resulting
curvatures.
5. Specifications and Addenda: Legibly mark up each Section to record:
a. Manufacturer, trade name, catalog number, and supplier of each product and
item of equipment actually installed.
b. Changes made by Change Order or Field Order.
c. Other matters not originally specified.
E. Submittal:
1. Upon Substantial Completion of the Work, deliver record drawings to
ENGINEER. Final payment will not be made until satisfactory "as-built' drawings
are received by ENGINEER.
2. Accompany submittal with transmittal letter containing:
a. Date.
b. Project title and number.
c. CONTRACTOR'S name and address.
d. Title and number of each record drawings.
e. Certification that each document as submitted is complete and accurate.
f. Signature of CONTRACTOR, or his/her authorized representative.

4. CADD Files -The CONTRACTOR shall provide a CD of the "as-built" drawings in
a digital format compatible with AutoCAD 2000 software.
5. The CONTRACTOR must submit partial plot files or hard copies of As-Built
drawings showing completed work with each partial payment requisition.
F. The CONTRACTOR shall be held responsible for the accuracy of such data and
