DESCRIPTION OF PROJECT

2.1 SUMMARY

The Contractor must provide all plant, labor, equipment, transportation, and tools required to replace, modify, and upgrade mechanical and electrical equipment in B847. The intent of this project is to replace all mechanical and plumbing equipment in the mechanical room/yard, and its associated electrical components, except for the boiler and water heater. Perform all work according to this Statement of Work (SOW), the Concept Design Drawings, and all related AF requirements and other codes and references.

2.2 BACKGROUND

B847 serves as the Base Operations HQs and is a vital facility for properly executing the mission. The building is roughly 8,420 square feet and is conditioned via a VAV system with a 25-ton McQuay chiller. Over the years, the mechanical equipment has begun to degrade and is in need of replacement, but only within the mechanical room and the mechanical yard. The ductwork and VAV boxes themselves have been replaced/maintained and are in good condition. The work required in this project includes, but is not limited to, replacement of the chiller, air handler, piping, insulation, pumps, and related electrical components. A full recommissioning and testing, adjusting, and balancing of the HVAC system will also be required under this contract.

2.3 SCOPE OF PROJECT

This project also includes the replacement of the mechanical room doors, the installation of LED lights throughout the mechanical room, and anything else necessary to meet the intent of this SOW.

2.3.2 Demolish and remove the existing air handler in its entirety, along with its variable frequency drive and all associated ductwork, dampers, and actuators within the mechanical room (up to wall penetrations) and through/above the roof where the intake/exhaust/relief penetrations are. In its place, furnish and install a new air handler sized to handle both the sensible and latent loads of the facility. The outside air intake for the air handlers needs to be located per UFC 4-010-01. Furnish and install all new ductwork, dampers, and actuators in the mechanical room, all new roof penetrations and ductwork/caps for the intake/exhaust/relief, and provide all curbing, flashing, and other roof work necessary. Coordinate roof work with the government to keep any roof warranty intact. Existing penetrations should be reused to the extent possible. No existing ductwork, dampers, or caps for the air handler should be reused within the mechanical room or on the roof. The air handler is to receive all new control valves, actuators, sensors, and gauges necessary, as well as a new VFD. Install new breaker(s) for the air handler and make any necessary upgrades to the air handler’s electrical service as needed.

2.3.3 Replace the chilled water system in its entirety. Demolish and remove the existing chiller in its entirety, including all chilled water piping, wiring, breakers, and disconnect switch. In its place, furnish and install a new Daikan chiller with integral controls compatible with JCI, extending the equipment pad as needed. Provide a new exterior disconnect switch, new breakers, and all new wiring. Reuse the existing conduit where possible. The chiller must be sized to properly handle the loads of the building, and it may not match the existing 25-ton unit. The underground chilled water piping can be abandoned in place by removing it to 6” below grade on the exterior and flush with the mechanical room floor on the interior. Fill both ends of this abandoned piping with concrete to cap the line and make repairs to the mechanical room floor to create a smooth finish. On the exterior, infill the area with dirt where the underground line is abandoned and provide like materials to match the surrounding area.

2.3.4 Demolish and remove the existing chilled water pump in its entirety along with its HOA switch. In its place, furnish and install a new base-mounted chilled water pump with a balancing valve and HOA switch. Demolish and remove all chilled water piping throughout the mechanical room. Provide all new chilled water piping from the chiller, through the mechanical room walls, and to the pumps, air handler, and any other equipment needed including all valves, actuators, sensors, gauges, and expansion tanks necessary for a complete system. Provide a new balancing valve coming off the chilled water pump.

Install a new chemical feeder for the chilled water system. All piping must be insulated.

2.3.5 Replace the heating water system in the mechanical room in its entirety, except for the boiler. This includes demolishing and removing the heating water pump, circulating pump, the pumps’ HOA switches, piping, expansion tank, valves, hydronic heater, and any other piece of equipment except for the boiler. Furnish and install a new complete heating water system including piping, base-mounted system pump with balancing valve, any needed circulating pumps, HOA switches, balancing valves, isolation valves, actuators, expansion tank, hydronic heater, sensors, gauges, chemical feeder, and any other piece of equipment necessary for a complete heating water system. All piping must be insulated.

2.3.6 Replace the make-up water, domestic hot water, and domestic cold water system/lines in the mechanical room in their entirety except for the water heater. This includes all piping, pumps, certified backflow preventer, valves, actuators, sensors, gauges, chemical feeders, exterior water spigot, and anything else that’s part of the systems. Furnish and install everything necessary for a new makeup water system, domestic hot water system, and domestic cold water system in the mechanical room. The existing backflow preventer must be returned to the government. All piping must be insulated.

2.3.7 Demolish and remove existing roof-mounted exhaust fan and its associated electrical service back to the panel. Furnish and install a new exhaust fan in place along with a new disconnect, switch, wiring, and breaker. Make any necessary roof alterations and repairs for the new exhaust fan to provide a completely sealed roof. Coordinate with government to keep any existing roof warranty intact. Provide a line voltage thermostat to control the exhaust fan to maintain a temperature of 104°F or below.

2.3.8 Demolish and remove the existing mechanical room doors in their entirety. Furnish and install new louvered-metal mechanical room doors with new weather stripping, door sweeps, hardware, hinges, lockset, and anything else necessary for a complete and functional product. Hardware must be Best 7-pin compatible. New doors must be factory finished to meet base standards.

2.3.9 Demolish and remove existing lights and fixture whips throughout the mechanical room. Furnish and install all new LED suspended lights with new fixture whips. Provide any new breakers, wiring, and conduit necessary. Existing switch may be reused.

2.3.10 Update all electrical panel schedules within the panels to account for any changes in equipment and associated breakers.

2.3.11 Throughout this project, reuse existing equipment pads when possible, making any alterations necessary. Upon installation of all new equipment, demolish any remaining unused equipment pads.

Perform all work necessary to repair and refinish the floor in these areas to match the surrounding floor.

If any equipment pads are altered, details must be added to the design outlining the changes.

2.3.12 Perform non-destructive hydrostatic testing on all systems after new piping is installed.

2.3.13 This facility will remain occupied and operational during the project. The contractor must provide temporary HVAC units to condition the building throughout the project duration.

Recommissioning and Testing, Adjusting, & Balancing

2.3.14 Recommissioning (RCx) & TAB will also need to be conducted under this contract on both the existing and new facility HVAC systems and equipment to ensure proper HVAC conditions throughout the facility. The contractor must provide a qualified independent, third-party team of technical, engineering, and operating personnel to systematically inspect, test, and verify the current operating condition of the facility’s HVAC systems. Based on their findings, the RCx & TAB team(s) will adjust all relevant systems and their interactions to optimize them for the facility’s occupants. This includes, but is not limited to, water flow, airflow, temperatures, humidity, the DDC system, and anything else that affects the conditioning of the facility. The contractor must furnish and install all valves, actuators, sensors, gauges, and other appurtenances on all new equipment, piping, etc. being installed under this contract as necessary to complete this work. This facility recently underwent a controls upgrade, so existing equipment not being replaced under this contract already has all new sensors, control valves, etc.

that should not need replacing, but the contractor is responsible for verifying this and providing everything necessary to ensure the system can be fully recommissioned under this contract. These findings and adjustments should be coordinated with the Government’s EMCS team to ensure the system and all required set points are set up as needed. Provide a Recommissioning Plan to the government for review and approval along with the 95% design at the latest, prior to beginning any sort of commissioning.

3.6.2 SUBMITALS AT INTERMEDIATE STAGES OF DESIGN COMPLETION: To facilitate review and feedback throughout the design process, designs are submitted at various stages of completion as follows:

1) 65% DESIGN SUBMITTAL: Contractor must submit 65% design documents within 28 days after Notice to Proceed (NTP). The 65% design must include complete and thorough detailing to leave no question as to how demolition and construction is intended. It must also include all load calculations and equipment sizing. All design documents must be clearly annotated (in both title block and revision block of drawings) with “65% REVIEW SET” and the date.

2) 95% DESIGN SUBMITTAL: Contractor must submit 95% design documents within 21 days after receipt of the “Approved” 65% design. The 95% design 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.

3) 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. If professionally stamped and sealed drawings are required for this project (paragraph 3.2), the approved construction set must include all stamped drawings. All final design documents must be clearly annotated (in both title block and revision block of drawings) with “APPROVED CONSTRUCTION SET” and the date.

4) For each holiday or extraordinary event in a submittal period, increase the required days for submittal by one day for each day in the event. Deliver no submittals within (before or after): one week of Thanksgiving; two weeks of Christmas; or one week of New Year’s Day. 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.

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 210 days. Due to long lead times, the nature of the work, and the need for temporary HVAC units, no on-site work is to begin until all equipment is either on-site or confirmed for delivery.

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 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 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.

4.3.5 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.

4.3.6 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:

New Year’s Day 1 January Martin Luther King’s Birthday Third Monday in January President’s Day Third Monday in February Memorial Day Last Monday in May Juneteenth Day 19 June Independence Day 4 July Labor Day First Monday in September Columbus Day Second Monday in October Veterans Day 11 November Thanksgiving Day Fourth Thursday in November Christmas Day 25 December

1) Observe Saturday holidays the preceding Friday. Observe Sunday holidays the succeeding Monday.

2) For weekend, after hours, or holiday work, submit a 72 hour advance written request to the CO, describing dates, locations, and types of work. CAFB has the right to approve or deny the request.

Work in CAFB occupied areas during extra-normal work hours require AF escorts in the occupied areas. Modification to contract sum or period of performance will not be allowed.

3) The Government’s request for Contractor to work outside of the normal duty hours must be justification for modification to contract sum or period of performance.

4) If CAFB observes an unscheduled holiday, participates in training exercises, etc. Contractor may be prohibited from working for part or the whole of a day. 14CES does not know how many or when these activities might be scheduled but anticipate not less than two per year. CMI will allow additional contract time for these disruptions. Zero-cost modification to period of performance will be allowed.

4.3.7 Construction Schedule: Submit preliminary schedule to the CO at the Preconstruction Meeting, but not later than fourteen (14) days after issuance of Notice to Proceed. After CAFB review and comment, revise and resubmit schedule within seven (7) days. Upon approval by the CO, the schedule becomes the official Construction Progress Schedule. Keep a copy available at Contractor (field) Office. This schedule will only be changed with prior approval of the CO through a contract Modification.

4.3.8 Construction Progress Schedule: Submit and maintain an accurate and current Gantt chart to track construction progress with a separate horizontal line for each major work activity of subcontractors, manufacturers, and suppliers. Vertical lines must identify the first workday of each week. Show complete sequence of construction by activity, identifying separate stages of work and other logically grouped activities. Indicate early and late start, early and late finish, float dates, and duration of each activity.

Revise chart weekly to accurately identify progress made, percentage completion, and projected completion date for each activity. Show activities modified and scope changes. Submit written report to identify problems, anticipated delays, corrective actions, and affected completion dates. Provide additional progress schedule information as requested by the CMI. Construction progress schedule update forms will be provided at the preconstruction conference.

4.5 MATERIAL SUBMITTALS AND SHOP DRAWINGS

4.5.1 Definitions: A submittal is a package of project information, samples, drawings, schedules, certifications, product data, etc., submitted to the Contracting Officer for Government review. A deviation is a submittal wherein Contractor identifies an item that is in agreement with the intent of the Contract Documents, but does not precisely conform to those documents and Contractor requests either substitution or change for the purpose of increasing the quality of the final product. A Submittal or Deviation of a system must be considered as an integrated collection of component parts.

4.5.2 Purpose: Submittals formalize Government review of Contractor choices in complying with the CDs and providing Minimum Installer Qualifications (Section 4.8.1). They also formalize Contractor’s proposed Deviations, color choices, shop drawings, etc. early enough in the contract time when changes will have less impact on the ordering of materials and products.

4.5.3 Accountability: Contractor is wholly responsible for the contents of a submittal. Contractor by act of submittal certify that all items listed or implied, fully meet the intent, materiality and requirements of the design, quality, and functionality of the CDs. Neither Contractor furnishing nor Government approval of a submittal either suspends or waives Contractor responsibility for full compliance with the CDs. This includes materials, equipment, equipment sizing, performance, etc. The Contractor maintains sole responsibility for providing a fully functional product that meets the intent of this SOW, performs as intended, and adheres to all applicable codes and standards.

4.5.4 Basic Compliance: Comply with all “Material Submittals and Shop Drawings” requirements of the SOW. All submittals must be delivered to the Contracting Officer within twenty-one (21) days of approval of the 100% design unless otherwise specified by the CO. Failure to deliver all submittals within this time period constitutes basis for the CO to refuse Progress Payments until all submittals are delivered to the CO.

4.5.5 Submittals must be accurate, easily legible, with all detail necessary for a thorough review. Every copy of Product data must clearly identify proposed models, options, and relevant design data including physical, functional, and utility connection requirements. Where practicable, render manufacturer data specific to this Project.

4.5.6 Contractor must…
