PART 3 - EXECUTION

3.01 Contractor Receiving CADD Files:

1. CADD Files will be provided after contract award and at Contractor request to the Technical Representative of the Contracting Officer (TRCO), normally after the mid-point of construction to ensure any contract modifications are shown on the final design drawings.

2. The Government will provide an electronic copy of the final design drawings and associated files to the Contractor at that point. The electronic copies will consist of the CADD files on CD standard format. The CADD files will be in the MicroStation version current at the time of design, prepared according to the base standards then in effect.

CEPD accepts either Microstation V8 or AutoCAD 2007 or the latest version.; CEPM requires the Contractor/AE to keep the original file type (Microstation V8 or AutoCAD 2006 or the latest version).

3.02 Submittals:

1. Acceptance and Quality Review by Government: The Government places a high value on the accuracy and detail provided in these as-builts. The contract shall not be considered complete until the as-built information is approved and accepted in its entirety.

2. 50% and 75% completion Submittal (Hardcopy Only): Submit for approval at 50% and 75% completion (with AF Form 3000) a full set of hardcopy contract drawings with “redline” changes indicated on the drawings. The as-built hard copy shall show all red lines in red color.

a. Mark all drawings as “50% AS-BUILT” or “75% AS-BUILT” as applicable in the revisions block of the title block area.

b. If no changes to the drawings are required, submit the hardcopy drawings with "no changes" printed in large red letters on the title sheet.

c. Do not submit drawings with stray markings or sketches made in the field which are not red and are not intended to convey as-built information. Do not create new drawings to convey as-built conditions. Submit all redline information on an otherwise clean sheet of "hard copy" contractor drawings. If necessary and upon request, the Inspector will provide an extra set of drawings for this purpose.

3. The Inspector will evaluate the submittal for correctness and completeness and either approve or disapprove them via notation on the AF Form 3000. If the submittal is disapproved, it will be returned to the contractor, along with directions for corrections. Incorporate these corrections into the drawings and resubmit with AF Form 3000 for approval.

4. After receipt of the Inspector’s approval and prior to updating the drawings electronically, contact the Inspector and make contact with the As-built Coordinator for the originating design office to discuss technical issues associated with preparing the final as-built drawings.

5. Final Inspection Set

a. Submit (with AF Form 3000) at Pre-Final Inspection a full set of harcopy redline as-built drawings for approval, along with a full set of electronic drawing files (sheet files and model files) provided by the Government per para. 3.01.2 above, modified electronically to reflect the reflect the redline changes made on the hardcopy drawings. Accomplish all changes to the electronic drawing files according to industry standard CADD drawing practices acceptable to the Government. . The as-built hard copy shall show all red lines in red color.

b. Maintain the file names and naming pattern of the files as provided by the Government.

c. Label the drawings as “Final As-built” in the revision block area of the electronic drawings.

d. Retain the existing model file and sheet file structure originally used to produce the drawings to create the final drawings. Maintain the links of the reference (model) files. For example, if the floor plan was a model file, any changes to the floor plan shall be accomplished on the model file. If utility lines were a part of the sheet file, the changes shall be made to the sheet file.

e. Also submit PDF format files of all drawings readable with Adobe Acrobat Reader. Format files are to be printed at a 1:1 scale on the original size sheet (no enlargement or reduction will be allowed for accurate plotting to the original size sheet).

6. The Inspector and As-built Coordinator will reevaluate for correctness and completeness and then provide either approval or further directions for corrections to the Contractor.

7. Resubmit (with AF Form 3000) complete submittals as directed until the Government provides full approval.

3.03 Format:

1. Provide electronic copies of the design drawings and as-built drawings either Microstation V8 or AutoCAD 2007 or the latest version.

2. Drawing elements shall be retained in original format. Raster elements may remain raster, and vector elements shall remain vector.

3. Make all changes in the colors and levels that match those in the original drawings that were provided by the Government.

4. Notes shall be legible and changes shall be shown clearly indicating differences, however minor, between actual construction and project drawings. Include corrections to underground utilities and unforeseen site conditions discovered during performance of contract.

5. Update the indexes of the electronic files to reflect any changes.

3.04 Utility Data: Provide the following exterior utility information as “smart lines” when already on the original drawing files. If smart lines were not used, then provide a separate file in Microsoft Word or Excel format with the following data, as a minimum, for each segment of utility lines:

Size

Material

Depth

Date Installed (Normally to coincide with warranty date)

3.05 Accuracy of Dimensions for Site Drawings: Locate all significant exterior features and utility lines within a one (1) foot accuracy for purposes of as-built submission, even if not changed during construction.

1. The locating may be accomplished by traditional survey methods or by global positioning system (GPS) satellite equipment supplemented by traditional methods where required.

2. Locations may be from existing buildings or from base monument system. Any existing structures used as a survey reference must be checked for conformity to NAD 83 surveying coordinates.

3. Recognize that the base maps which are often the basis for the contract site plans have been prepared from aerial photographs and as such show the roofline instead of the building structure line.

3.06 Qualified Firms for CADD and GPS Support: The Contractor may use any commercial firm or in-house resources to accomplish the requirements. In some cases we used an Architect-Engineer (A-E) firm to design the project, and in those cases they are noted on the Drawings and may be used if desired. If requested, the Inspector will also provide names of other firms the Government believes should be capable of providing the services required, based upon base personnel experience with them.

3.07 GIS Submittals for Facilities and Utilities: (Omitted.) This project also requires data and CADD drawing info for updating the Robins AFB GIS/Geobase data system.

1. GIS Software: The Robins AFB GIS utilizes the ESRI Suite of GIS products. Deliverables to RAFB must be compatible with ArcGIS 8.3 or newer.

2. IGDS File Format - IGDS Graphic File Format: All graphic files are to be supplied in Autocad 2007.dwg file format. The symbology of graphic features must comply to Tri-Service Spatial Data Specifications (TSDDS) Version 2.40.
