3.1 General Facility Layout

The facility layout shall conform to the design as supplied in ANNEX B

3.2 Elements interfering with the new construction

It is estimated that new construction shall be placed in an area without any prior construction within its footprint. However, it is possible that there will be underground utility lines which may need to be rerouted in coordination with the construction of the new facilities. The contractor is responsible to survey the area prior to submission of their bid or to place the building where it does not interfere with any utility line.

Anything interfering with the new construction and extending more than 1 meter above or below the new facilities shall be rerouted (if still in use) or demolished by the contractor if no longer in use. The contractor shall locate and reroute any potential utility line (cables, piping, etc.) that may interfere with new construction.

The contractor shall design the construction to minimize removing any tree. The removal of any tree shall be done by the beneficiary following the same principle: contractor to notify the beneficiary with 2 months advance notice and contractor to remove what will be left under grade elevation.

The contractor shall copy the Contracting Officer Representative on any official correspondence related to this PTS between the contractor and the beneficiary.

3.3 General Design / Construction Requirements for Structures

General requirements:

- Emergency Escapes: The building shall comply with the emergency escapes requirements of the

Bulgarian regulations. All exterior doors shall open to the outside and be equipped with the required panic hardware.

- Ceiling height: 2.8 meters from finished floor to suspended acoustic ceiling

- Windows: The contractor shall provide the necessary windows to maximize the use of natural light, to provide ventilation and to provide an esthetically pleasant building.

- Structure: Reinforced concrete superstructure: foundations, columns, beams, deck. No wood shall be used as a permanent structural member.

- It is noted that the design of the foundations depends on the results of a geotechnical report, which is not included in these PTS. For estimating purposes, the contractor shall estimate the worst soil conditions available in this part of Bulgaria. The contractor needs to be familiar with recent construction projects in the area to estimate the necessary foundations for the new facility.

Contractor needs to obtain this information from beneficiary, from Ministry of Defense, or from other local sources, prior to submission of their bids.

- Exterior Enclosure: Use traditional solid natural stone bricks or other concrete masonry units (CMU) authorized by Bulgarian construction standards with masonry walls, with rigid thermal insulation, mesh, plaster, and paint. Provide similar finishes as the existing installation HQ building.

- Internal Partitions: Masonry walls, plastered, and paint. The rest of interior partitions shall be made with ceramic masonry walls, as thin as allowed by Bulgarian regulations to maximize the usable area of the new facility.

- Seismic: Strict compliance with seismic criteria applicable for this region of Bulgaria. It must be noted that the seismic requirements in Bulgaria are very high, which will require very heavy reinforcements and building structure.

- Elevation: Ground floor of new construction shall be 0.3 m higher than average grade elevation surrounding the new building.

- Drainage: Provide adequate drainage system around the new construction. The contractor shall grade the grounds around the new construction as far as technically necessary to guarantee that there will not be any accumulation of rain water next to the new construction. This will require underground drainage or sloping and grading of all the areas.

- Roof: Similar to installation’s existing HQ’s building. Provide thermal insulation on the roof. Provide with minimum 0.8 meter wide roof eaves.

3.4 Requirements for Support Building

Some rooms will have specific requirements that are described in later in this PTS.
