1) 35% DESIGN SUBMITTAL: Contractor must submit 35% design documents within 21 days after Notice to Proceed (NTP). The 35% design must include complete and thorough detailing to leave no question as to how demolition and construction is intended. All design documents must be clearly annotated (in both title block and revision block of drawings) with “35% REVIEW SET” and the date.

2) 65% DESIGN SUBMITTAL: Contractor must submit 65% design documents within 21 days after receipt of the “Approved” 35% design. The 65% design must include complete and thorough detailing to leave no question as to how demolition and construction is intended. All design documents must be clearly annotated (in both title block and revision block of drawings) with “65% REVIEW SET” and the date.

3) 95% DESIGN SUBMITTAL: Contractor must submit 95% design documents within 21 days after receipt of the “Approved” 65% design. The 95% design (essentially complete design and drawings, pending review and acceptance by Government as the 100% APPROVED CONSTRUCTION SET) must include complete and thorough detailing to leave no question as to how assembly is intended. All design documents must be clearly annotated (in both title block and revision block of drawings) with “95% REVIEW SET” and the date.

4) 100% DESIGN/APPROVED CONSTRUCTION SET: Contractor must submit the 100% DESIGN APPROVED CONSTRUCTION SET within 14 days after Contractor receipt of the “Approved” 95% design. The construction set must incorporate and/or address any Government comments on the 95% design and should leave no question to how demolition and construction will be done.

Extraordinary Events include: unscheduled holidays for base personnel; base-wide training exercises; etc. The Government may prohibit work during such events.

3.6.3 PARTIAL SUBMISSIONS: Partial submissions normally will not be accepted. However, under some circumstances, to expedite project execution, the Government may accept design/shop drawings or material submittals for major elements or long-lead-time equipment for review and approvals prior to 95% design submittal. Government approval of such items does not relieve the Contractor of his responsibility to ensure a complete, constructible, code-compliant design.

3.6.4 CONSTRUCTION PRIOR TO 100% DESIGN: Construction may not commence until Government approves the 100% design. Exception: To expedite contract completion, Contractor may petition CO for an Interim Notice to Proceed with specific elements of construction. Government review does not constitute approval or acceptance of any variations from this SOW, the Contractor’s Proposal, or the Contract unless authorized in writing by the CO. The Interim Notice to Proceed, if exercised, will in no way mitigate the responsibility of the Contractor to provide a complete, constructible, code-compliant design.

All drawings, specifications, design analyses and other project materials become the property of the Government.

3.7 DESIGN REVIEWS

3.7.1 DESIGN PHASE REVIEWS: Government review of each XX% design submittal (where XX = 95 or 100 as required per 3.6.2) will require up to fourteen (14) days after Government receipt. The Government will determine the sufficiency of each XX% design submittal as follows:

1) Approved as Submitted. If design is sufficient to proceed without correction to the next phase submittal, one (1) copy of AF FORM 3000 marked "Approved" will be returned to the Contractor.

Contractor must advance to the next stage design submittal.

2) Approved - Except as Noted. Design submittals that have only minor errors or deficiencies will be marked in red to indicate necessary corrections. Marked materials, along with one (1) copy of AF FORM 3000 indicating "Approved - Except as Noted" will be returned to the Contractor.

Contractor must revise the design documents, making the necessary corrections, and advance to the next stage design submittal.

3) Disapproved. Design submittals that are incomplete or require more than minor corrections will be marked in red to indicate necessary corrections. Marked materials, along with one (1) copy of AF FORM 3000 marked “Disapproved” will be returned to the Contractor. Contractor must revise the design documents, making the necessary corrections, and re-submit as the current stage “XX% Design – 2nd (or subsequent) Submittal”.

4) Disapproved – Major Deficiency. Examples include, but are not limited to, design submittals that fall significantly short of indicated level of completion, grossly deviate from or misinterpret the SOW, or contain errors of a nature or quantity that indicate failure of Contractor to review submittals for completeness, correctness, and coordination between trades. For such submittals, the Government will not complete a comprehensive review or provide an exhaustive list of needed corrections. Rather, one (1) copy of AF FORM 3000 marked “Disapproved – Major Deficiency” along with general reason(s) for disapproval will be returned to the contractor. The CO will issue a written warning to the Contractor that any subsequent grossly incorrect/incomplete submittals constitute evidence of inability to complete the project and may result in declaring the Contractor “In Default.” Contractor must correct deficiencies and resubmit as current stage “XX% Design – 2nd (or subsequent) Submittal”.

3.7.2 100% DESIGN REVIEW: The Government will have fourteen (14) days to verify that all review comments have been addressed and no unapproved changes have been made. Upon Government approval of the 100% design documents, the Contractor may begin construction.

3.7.3 IMPACT OF REVIEW ON PERIOD OF PERFORMANCE: Contract completion time includes time for Government review of drawings, specifications, and material submittals. Unless otherwise noted, the Government will use no more than 14 calendar days for review of each design submittal and each subsequent re-submittal of “Disapproved” submittals (paragraph 3.7.1, c or d). There will be no increase in the period of performance for review of re-submittals.

3.7.4 RESPONSE TO REVIEW COMMENTS: The Contractor is required to respond to all review comments and submit their annotated comments as a design analysis appendix in the subsequent design submittal. All comments must either be accepted and incorporated into the next design submittal or satisfactorily rebutted.

3.7.5 DESIGN ACCOUNTABILITY: The Contractor is solely responsible for accurately designing and constructing everything necessary to provide a fully functional product. Government approval of any design or design-related submittal does not waive or remove full liability from the Contractor to provide a design, facility, or final product that meets the intent of this SOW, performs as intended, and adheres to all applicable codes and standards.

3.8 CONFERENCES

3.8.1 PRECONSTRUCTION CONFERENCE: A Preconstruction Conference (Pre-Con) will be held at the Contracting Office as indicated.

3.8.2 COORDINATION/REVIEW CONFERENCES: Coordination/review conferences may be held from time to time as required. The Contractor may request such conferences when it is deemed necessary by both parties to clarify the work or expedite the preparation of plans, specifications or construction.

3.8.3 REVIEW/CONFERENCE MINUTES: The Contractor will be responsible for making memoranda of record of any conversations and minutes of any meeting with Government personnel concerning this project and forward one copy of these memoranda/minutes to each party concerned and one copy to the Contracting Officer within seven (7) days. The final version of the meeting minutes will be approved and filed at the CO’s discretion. Each copy will be numbered consecutively and chronologically.

3.8.4 MEETING LOCATIONS: Meetings will be held in person at Columbus Air Force Base.

Contractor transportation costs for attending all conferences/reviews and meetings must be included in the Contractor’s Proposal. There will be no teleconferences unless permitted otherwise by the Contracting Officer.

ADMINISTRATION OF CONSTRUCTION

4.1 PERFORMANCE CAPABILITIES

4.1.1 One week prior to the start of work under this contract, Contractor must submit in writing to the CO for review and possible approval the names and credentials of Contractor Project Manager, Contractor Site Superintendent, and Quality Control Manager. Subsequent proposed changes of approved personnel must be submitted in writing to and receive prior approval from the CO before working on the project. Each of these personnel may upon CO approval hold additional onsite duties which must not diminish their required performance. Contractor must demonstrate to the Government’s satisfaction that proposed personnel exceed education, technical and experience levels of personnel described in this Contract including the following:

1) Contractor Project Manager (CPM) - Provide management of the prime contract to include subcontract purchasing and administration, review of material submittals and shop drawings. CPM must have full authority to develop cost proposals, negotiate with Government and subcontractors, sign awards and modifications, supervise project superintendents, attend weekly CO/CE/PM Contractor status meetings as well as pre-performance site visits, pre-final and final inspections.

The CPM must have a minimum of 5 years previous experience as primary contract manager or equivalent experience as a primary estimator and negotiator with a contracting firm engaged in similar multi-discipline commercial construction projects. CPM must also have not less than 5 years’ experience managing subcontractors.

2) Contractor Site Superintendent (CSS) - Provide on-site construction superintendent(s) to oversee all work under this contract. Site supervision must be daily (constant throughout each day) and includes submission of detailed weekly progress reports, scheduling and coordination of subcontractors and material suppliers, and attendance at all construction progress meetings, CO site visits, and pre-final and final inspections. Superintendents must have a minimum of 5 years previous experience as a project superintendent (exclusive of time employed as a tradesman or working foreman) for a general contracting firm overseeing one or more multi-discipline commercial construction projects. The superintendent must be available within 15 minutes during all normal working hours, except for such incidental errands as required by his duties. The superintendent must be responsible for the proper coordination and timeliness of the work, and for the proper workmanship of all trades; therefore, his absence from the project site without a suitable substitute Contractor representative must be considered as damaging to the Government.

3) Quality Control Manager (QCM) - Provide quality control management for the project. QCM must continually (constant throughout each day) ensure full compliance with all safety requirements, verification that work and materials in place and stored on site are in accordance with the approved construction documents, shop drawings and material submittals.

4.1.3 Contractor must be available by telephone 24-hours a day, 7-days a week and upon 15 minutes’ notice during normal duty hours and 30 minutes’ notice during non-duty hours must meet the CO at a CO designated location.

4.2 COMMENCEMENT, PROSECUTION & COMPLETION

4.2.1 Contractor must start design and various construction phases at times specified by CO issued Notice(s) to Proceed (NTP), prosecute the work, and complete the entire work within the Period of Performance.

4.2.2 Contractor must provide a Submittal Log (Schedule of Material Submittals), Progress Schedules, Progress reports and Status Reports.

1) Submittal Log: See Material Submittals and Shop Drawings below.

2) Progress Schedule: (AF Form 3064) Submit the progress schedule to the CO within 10 days after contract award, unless otherwise specified by the CO. Subdivide total schedule into individual work items. Show completed work percentages at the end of each two-week reporting period. Progress schedule should only be resubmitted during the project duration if there’s an issue with Period of Performance or if deemed necessary by the CO as described in 4.2.2.3.

3) Progress Reports: (AF Form 3065) Submit Project Progress reports to the CO minimum twice per month on the first working day of each month and again on the 15th. Describe the percentage of work completed during the report period. If behind schedule, report in writing what actions will be taken to regain the schedule. If the CO agrees to add days to the contract performance period, Contractor must provide an amended schedule.

4) Status Reports: Submit to the CO daily reports of the work status. In each report, list the tasks accomplished for that day, any deliveries received, equipment currently on-site, weather conditions for that day, and number of personnel working on each area listed by trade. Photos may be included.

4.2.3 Period of Performance: Is the period between the issuance of the NTP and the time all construction is complete, including all punch list items, and final inspection is approved by the Government. The total Period of Performance for this project is 330 days.

4.2.4 Contract Completion: At contract conclusion, vacate all work areas, including: Contractor offices, storage and staging areas, and individual work sites. Restore these areas to their condition prior to Contractor occupancy not more than 14 days from the earlier of: approved final inspection or CO notification.

4.2.5 Coordination and Project Conditions: Schedule and manage submittals, materials, products, equipment, manpower, etc. to control all parts of the work efficiently and orderly. Verify compatibility of existing building utilities with new operating equipment. Coordinate required space, supports, and mechanical and electrical work shown (even if via diagrams) on Drawings. Follow routing shown for pipes, ducts, and conduit; place runs parallel with building lines. Use space efficiently to maximize maintenance and for repair accessibility for other systems. Conceal wiring behind finish surfaces and locate fixtures and outlets with finish elements. Coordinate pre-Substantial Completion clean-up in separate building areas.

After CAFB occupancy, coordinate site access to correct defective (or non-compliant with CDs) to minimize disruption of Government activities.

4.2.6 Cutting and Patching: Only employ skilled and experienced workers to cut and patch. Report in writing to the CO wherever cutting and patching might degrade: safety; appearance, structure, weatherproofing, O&M, or separate Contractor or government construction. Prevent damage to existing or new construction and provide proper surfaces to receive patching and finishing. Match new finishes to existing adjacent surfaces unless noted otherwise. Maintain integrity of existing walls, ceilings, or floors;

completely seal voids. Refinish entire assemblies and continuous surfaces to nearest intersection. Cut, fit, and patch where CDs require e.g.: mechanical and electrical penetrations; integration of new components with one another or with existing construction; removal and replacement of defective and non-conforming elements; remove samples for testing.

4.2.7 Special Procedures: Employ skilled and experienced tradespersons to perform alteration work.

Remove debris from open work areas and concealed spaces. Remove, cut, and patch to minimize damage and provide means of restoring products and finishes to original or specified condition. If a change of plane of 1/4 inch or more is discovered, submit recommendation to the CO for providing a smooth transition.

Patch or replace portions of existing surfaces which are damaged or showing other imperfections. Finish surfaces as specified.

4.2.8 Airfield Waiver: The work will be done on or near an active airfield and special considerations apply for vehicle traffic control and work in the vicinity of the airfield. A FOD control plan must be established and maintained at all times. Vehicle operators must be trained on flight line driving procedures prior to entering the airfield. Disruptions to airfield activities must be scheduled with the Government in advance. The airfield is a controlled area; contractor shall comply with CAFB controlled area procedures. Coordinate with the Government and provide any assistance needed to prepare an Airfield Waiver. Work may not start on the airfield until the waivers are approved. Waiver information shall be supplied a minimum of 30 days before desired start date.

4.2.9 Welding Permits: No cutting or welding will be permitted without first obtaining a permit issued by the Base Fire Department. All fire and safety regulations are to be followed stringently. Contractor’s failure to obtain a cutting or welding permit may not be reason for extending the contract performance period. Any damages incurred while welding work is done without a permit are the responsibility of Contractor.

4.3 SCHEDULING

4.3.1 Contractor must coordinate all work schedules and manage progress of work with the CO and CEPM prior to start of work. Weekly progress meetings will be conducted with the CO, CMI, and Contractor’s team which may require corporate management representation at CAFB discretion.

4.3.2 Contractor must schedule all work. Performance periods must not be established or extended to accommodate insufficient personnel resources. Contractor will not move crews on and off the project while making minimal progress on concurrent projects as this must be construed as having an inadequate work force to fulfill the contract requirements. Contractor’s CPM and CSS must not change more than two (2) times during project construction as this would demonstrate an inadequate management force to fulfill contract requirements.

4.3.3 Before construction begins, Contractor must agree with CO on a sequence of procedures; means of access to premises and buildings; materials and equipment storage space; delivery of materials and use of approaches, corridors, and stairways. Contractor may be required to revise the CD work-phasing schedule.

4.3.4 Contractor must ensure that all required materials, equipment, and labor is available and on-site before beginning construction actions of this project. Contractor shall notify the Government when everything is available and on-site, and receive approval by the Government to perform construction actions of this project.

4.3.5 Interference and inconvenience to Government operations and personnel caused by project work including use and delivery of materials, tools and equipment must be kept to a minimum.

4.3.6 The Government may require that work, so far as practicable, be done in separate phases. Each phase may relate to a different occupied or unoccupied area, in which work in one area must be completed before work in another area may begin. Phased work areas must be clearly delineated and annotated in the CDs.

4.3.7 Hours of Work: Normal work hours will be Monday through Friday from 7:30am to 4:15pm excepting days observed as Federal Holidays as listed below:
