PART 1 - GENERAL PROJECT DESCRIPTION

1. This project is intended to provide new HVAC systems for buildings 101 (Head Quarters) and 414 (Hazardous Storage). The project shall also renovate electrical service lines, electrical service entrance and electrical distribution and lighting within the mechanical room of Bldg 101 (Head Quarters). Also, associated architectural modifications are included.

2. Building 101 (Base Head Quarters) was constructed in 1958, with minor modifications along the years. The complete HVAC system was replaced in 1993. In 2001, a new pitched roof was installed and the HVAC equipment was replaced. No major renovations regarding the electrical system have been performed since the original construction, but there have been multiple small size modifications performed by base electrical shops.

3. Building 414 (Base Hazardous Storage) was constructed in 2001, with minor modifications since then.

PART 3 - SCOPE

1. GENERAL: The work covered by this Statement of Work (SOW) consists in the design and build of the project, performing all necessary travels and furnishing all professional services, facilities, labor, equipment, materials, plants, transportation, specifications, detailed drawings and cost estimates that enable the Contractor to construct a complete and usable facility under a firm fixed price contract. The Contractor shall investigate site conditions, perform topographic surveys (geographic information system) at each facility and utilize manufacturer’s standard installation plans, specifications and drawings to the maximum extent feasible in developing the final design documentation necessary for obtaining Government approval. Any design change suggested by the Contractor to the SOW requires the approval of the Contracting Officer before its acceptance is given. The Contractor shall be responsible for the temporary markings, signs, markers and lights at the area affected by the construction and, if required, shall provide the flagmen, escorts and foreign object debris controllers during the work hours.

2. WORK DESCRIPTION: The construction works consist of, but are not limited to, the items indicated below, including the testing to be performed by independent laboratories for quality control. All items do not limit or reduce the Contractor’s responsibility to design and build all works as required by the project in order to provide a complete, operational and low-maintenance facility.

2.1. The project consists in the design and construction works to install new Heating, Ventilation and Air Conditioning (HVAC) systems in buildings 101 and 414, renovate electrical service entrance and electrical installations in mechanical room (only for building 101), and related architectural works.

The two general phases of the project shall be the Design Phase and the Construction Phase. A unique notice to proceed (NTP) for both the design and for the construction phases will be issued. The design and construction phases below can be balanced, i.e.: if the Contractor completes the design faster, the remaining time can be used for construction; on the contrary, if the Contractor design is delayed, the construction period shall be shortened accordingly, so the overall project performance period shall be maintained at no extra cost to the Government in case that the Contractor needs to increase resources to accomplish the overall contract. The construction phase shall consider the phasing plan required to perform works with minimum interferences to Base operations and security, including a Construction Phasing Plan, if needed. The estimated project phases (not to exceed days) will be as follows (see next page):

Milestones Periods Contract Award – Notice To Proceed (NTP).

Kick-off meeting Any time within NTP+25 calendar days.

35% Design Review Submittal Preparation NTP + 30 calendar days.

35% Design Review and Approval NTP + 60 calendar days.

4.1 The total performance period proposed for this project is 400 calendar days, including the design, the preconstruction, construction and finish activities and average inclement weather days.

The start of construction can be requested by the contractor before the design phase is completed. In this case, the Contractor should request an updated AF103 from the Contracting Officer when preparing to mobilize for construction, the updated AF103 can be requested before design has been finalized and construction shall not start until receiving the AF103 from Contracting Officer.

5. The Government design review continues through the 100% design to provide direction, as pertaining, to the quality and content of the documents.

PROJECT QUUG 22-1015 Page 18 of 130

SOW 18 of 130 shall be placed on this coordination when certain elements of the design are performed under sub-contract to the A-E contract. Drawings shall be prepared in order to avoid errors, omissions, inadequacies or conflicts with the specifications. Applicable parts of the following design data shall be shown on the drawings.

5.7. Format for Drawings:

5.7.1. AUTOCAD Requirements: All designs shall be accomplished in AUTOCAD 2023 or higher and shall be submitted on CD ROM and in one set of Mylar reproducible.

5.7.2. Size of Drawings: The A-E shall use drawing size DIN A-1 841 mm x 594 mm in all cases unless specifically directed to use another size.

5.7.3. Lettering and Shading: The minimum size lettering on all project drawings shall be

2.5 mm high. Make minimum gap between lines equal to one-half the letter height. Shading is not acceptable.

5.7.4. Scales: Locate it directly under the title of each plan, elevation, section and detail and shall be an indication of the scale of the object drawn (example: SCALE 1:100) on the metric system unless otherwise approved. In addition to the conventional scales, and directly to the left of the title block, shall be a series of graphic scales, which shall include every scale used on the sheet. Scales shall be placed in sequence according to size with the smallest uppermost. If it is not sufficient to place all scales on one sheet, each sheet must be treated independently, as the drawings used usually are reduced in size and not always at scaled. For these reasons, it is imperative that graphic scales be shown.

5.7.5. Title Blocks: Sample of title block is available at Morón Air Base, Bldg. 202, Design Section.

5.7.6. Arrangement of Drawings: Drawings shall be arranged and comply with the A/E/C CAD Standard – Release 5.0, prepared by the CAD/BIN Technology Center.

5.7.8. Drawing Orientation: The orientation of drawings shall be arranged with North toward the top (or left edge, if better suited) of the plotted sheet and perpendicular to the sheet borderline. On individual sheets, if the shape of the area dictates, the North symbol can be oriented between these directions to accommodate the site. For example, on drawings having excessive longitudinal but limited lateral dimensions, such as those for roads and railroads, the North symbol can be oriented obliquely to make the best use of available space. All drawings of the same discipline shall be consistent in orientation in so far as practicable.

PART 5 - PERFORMANCE TECHNICAL SPECIFICATIONS

1. ARCHITECTURAL WORKS

1.1. An inspection will be carried out with the necessary means of the existing damaged structural elements, wall of the previous enclosure and beam, among others. After the inspection and revision of the state of the elements, we will proceed with the necessary restoration and reinforcement.

For the brick masonry element with existing crack, we will proceed to demolish the extreme part and then reinforce either with solid brick interlocking to the sound wall or by another method such as steel pillar as deemed necessary by A&E . Depending on the solution, partial demolition of the brick masonry will be performed.
