IV. EXISTING CONDITIONS CONSIDERATION

A. The design and analysis shall be calculated based on the attached drawings.

SOW-4

B. The contractor is responsible for correcting any unplanned / unapproved adverse impacts to the facility due to their work at no additional costs.

V. DESIGN POLICY AND CRITERIA

A. The Government will furnish the basic design criteria to the contractor from which the project documents can be developed and produced as described below. Suggestions that will improve the operational functions, enhance appearance, and prove to be more economical and advantageous shall be made at the appropriate review conferences. Meeting minutes shall be provided by the contractor within 3 working days from the date of conference. The design must be accepted by the government before construction can start.

1. Design instructions: The design shall incorporate the requirements as discussed in the pre and post-award conferences and site visits as well as the requirements of the publications listed below. Modern construction techniques may be incorporated into the project design to obtain both quality and economy and to provide a functional, complete, and useable facility.

2. Cost saving techniques: The design is to provide functionality without embellishment.

Also, the design is to achieve an optimum balance between aesthetic consideration, operations and maintenance costs, energy conservation measures, and durability of materials and systems. Design and support items will be limited to the minimum essential support construction required to provide a useable facility. Every effort will be made to reduce utility runs and site preparation requirements through proper design.

B. Government furnished information: The age of government data and as-built drawings, along with the fact that there has often been undocumented tenant construction, reduces their usefulness and reliability. The contractor shall verify the data shown on government-furnished reference documents by performing reconnaissance, surveys, and field measurements. The following information (see XIII. ATTACHMENT) will be furnished by the government for the execution of this project.

VI. DESIGN SERVICES

A. Site design data: The contractor shall perform site investigations/surveys in accordance with requirements of this project. During the site data collection, the contractor shall record all existing conditions (inside and outside) and obtain engineering information/design data for the accomplishment of this project. All material sampling, testing, and removal shall be performed in accordance with the JEGS.

B. Field measurements: The contractor is required to make field investigations to verify dimensions and other information shown on Government-furnished reference data and drawings.

C. General: The contractor will consider all design options and criteria reductions that may be necessary, in those instances, where possible cost overruns may be expected. All drawings, and specifications shall be prepared, reviewed, and approved by registered professional architects and engineers. All hardcopy and electronic submittals of the drawings, specifications, basis of design, construction schedule, and submittal register shall be submitted and delivered to the contracting officer. One copy of the final drawings shall be submitted in specified editable electronic format for incorporation into Geobase.

SOW-5

1. 60% Design: 60% design submittals shall be based on the concept drawing. The preliminary design submittals will include detailing of the requirements of the project so to leave the reviewer no question as to scope of this project.

2. 90% Design, and 100% Design (including 100% corrected final): The final submittals shall be based on the previous submittals and comments furnished by the Air Force along with an anticipated design/construction time schedule (bar chart). The Final Design submittals will include all requirements shown on the Preliminary Design, a complete and thorough detailing of all the requirements of the project.

3. The design will not be deemed 100% Final until the government has accepted all response(s) to comments made on previous submittals. The contractor shall make such required revisions at no additional cost to the Government. It is recommended that the contractor electronically submits to the government a compilation of response to comments along with pages / drawings / calculations that will change between 90% and final submittal. This will minimize the possibility of multiple versions of Final Design, (such as 100% Corrected Final Design 1, 100% Corrected Final Design 2, etc.)

4. Design submission copy quantities: All submittals shall occur in the number and format as prescribed below:
