ARCHITECTURAL DESIGN NARRATIVE

A01 – DESIGN OBJECTIVES

1.1 SCOPE OF WORK

The Architectural & Engineering renovation of the Royal Bahamas Police Force Police College in Nassau, Bahamas, results from a need expressed by the RBPC to upgrade and bring to code compliance the two main buildings of their compound. The existing facility is intended for police administration, training and support.

This 100% submittal is made in preparation of design-bid-build construction documents for the renovation of four buildings totaling 19,872 square feet (SF). As identified within the plans, the scope includes the following building areas:

Building #5: 1st floor 6662 SF, 2nd floor 1241 SF.

Building #5A: 1st floor 2041 SF

Building #8: 1st floor 6646 SF, 2nd floor 1241 SF

Building #8A: 1st floor 2041 SF

Elements of the renovation as defined within the scope of work are included below.

1.2 ROOF REPLACEMENT

A new hurricane-rated roof is a priority for the Administration Building, as the aging asphalt shingle roofing, and prior repairs, are reportedly leaking. Many torn shingles and patches were visible during our site visit in January 2019. After inspection of the roofing, the fastener pattern of shingle attachment to plywood decking is deemed inadequate to resist wind loads required by the Bahamas Building Code.

The specifications offer three roofing options, however the cost estimate is based upon roof replacement work recently completed by the College on Building #5 with shingles. You may choose between asphalt shingles made for hurricane force winds, standard asphalt shingles with a nailing pattern to resist hurricane force winds or optional metal roofing. Metal roofing is a better product but a direct hit by a big hurricane will tear it off just the same as asphalt shingles. The standard warranty period for both metal roofing and asphalt shingle roofing is 10 years. The asphalt shingles specified are not intended to match existing, although they could be matched. The new roof assembly includes self-adhered underlayment, not roofing felt, for better protection from wind-driven rain. The performance requirements in the specifications will make it more secure with an enhanced nailing pattern for greater wind resistance.

1.3 EXTERIOR WINDOW AND DOOR REPLACEMENT

Replacement of all exterior windows and doors is not possible with the current construction budget based upon our cost estimate. However, we are proposing to replace all exterior windows and doors within the main (2) buildings closest to the street within the base bid and bid alternate #1. The only caveat is that window and door replacement for rooms 8-15, 8-16 and 8-17 is within Bid Alternate #5, and rooms 8-12 and 8-13 are excluded as work in these rooms is planned to be performed locally by the

RBPF outside of this construction contract.

We have specified all second story windows to be replaced within the base bid package, to take advantage of scaffolding needed for the roof replacement work. With the balance of money in the base bid package we’ve specified windows visible from the street and other windows and doors within those rooms to be replaced. The remainder of windows and doors within buildings 5 and 8 are within bid alternate #1.

1.4 INTERIOR ROOM UPGRADES

Interior room upgrades including all new floor, wall and ceiling finishes are not possible with the current construction budget based upon our cost estimate. As presented to the RBPC during our site visit debrief meeting, we propose to upgrade finishes primarily in the classrooms. This work is designated to be within the construction contractor’s bid alternate #5 as lowest priority.

1.5 EXTERIOR FINISH REPAIRS

Exterior finish upgrades, which includes repair/replacement of damaged masonry have been included within the construction contractor’s base bid package.

1.6 TOILET AND SHOWER ROOM REFURBISHEMENTS

Complete toilet room refurbishments, including fixtures and room finishes, are not possible with the current construction budget based upon our cost estimate. As presented to the RBPC during our site visit debrief meeting, we propose to provide a complete upgrade of the bathrooms serving the mess hall and canteen.

These bathrooms are currently unconditioned and in disrepair with original plumbing pipes. Other building bathrooms have recently had new piping and fixtures replaced and are functioning adequately.

This work is designated to be within the construction contractor’s bid alternate #3.

1.7 KITCHEN UPGRADES

High priority life-safety and health-safety kitchen upgrades, including equipment and room finishes have been included. A new washroom area will be created, a new vent hood with fire suppression installed, new water supply piping installed to replace aging galvanized steel pipes, new electrical wiring installed and a new HVAC unit installed. This work is designated to be within the construction contractor’s base bid package.

1.8 COMPUTER LAB UPGRADE

A computer lab upgrade, including room finishes and network wiring/wifi (but not including new network equipment or computers) was included within the contract scope of work. After discussion with the RBPC, the room finishes are adequate, except a new raised floor system is requested to provide a level floor surface and allow wiring to be concealed for multiple desk configurations. In addition, the offices will be removed and replaced with one central office for ease of instructor use. This work is designated to be within the construction contractor’s bid alternate #5.

1.9 MAIN ELECTRICAL SERVICES UPGRADE

Main electrical service upgrade, including electrical distribution panels was requested. We recommend the replacement of all building mounted electrical distribution panels, branch panels and equipment disconnects that are currently non-code compliant. These pieces of equipment create a life safety issue that should be remedied. It appears the main electrical service is adequate for the building demands.

Upgrade of the service transformer, main disconnect and transfer switch, and generator are not possible with the current construction budget. Those pieces of equipment will remain in service as is. This work is designated to be within the construction contractor’s base bid package.

1.10 ELECTRICAL UPGRADES

Electrical upgrades, including interior and exterior lighting, power outlets, etc. for all rooms are not possible with the current construction budget. We are recommending new lighting within the classrooms primarily. In addition, code required life-safety upgrades for exposed above ceiling wiring and wire splices is being recommended.

Code required life-safety upgrades are designated to be within the construction contractor’s base bid package. New lighting within classrooms is designated to be within the construction contractor’s bid alternate #5 to be performed when ceilings are replaced or repaired.

1.11 HVAC UPGRADES

HVAC upgrades, including spilt system A/C units, exhaust fans, etc. are being recommended for all units that are at or nearing the end of their service life. New exhaust fans are being specified in the bathrooms to provide ventilation. This work is designated to be within the construction contractor’s bid alternate #4.

1.12 HAZARDOUS MATERIALS

Hazardous materials are present in buildings and structures to be selectively demolished. A report on the presence of hazardous materials was received just prior to the release of our 100% documents. This report should be examined by bidders and contractors to become aware of locations where hazardous materials are present.

Laboratory analysis of the samples for suspect materials determined that asbestos is present in the ceiling panels and 9” x 9” vinyl floor tile with black mastic. Toilet room mirrors are assumed to be adhered with asbestos-containing mastic. Ceiling panels and mirror mastic require abatement as described in this report and in Division 02 Specification sections. Vinyl floor tiles, if undisturbed, may remain in place. Lead is present in buildings, though only trace amounts well below EPA allowable levels were found in areas tested.

Hazardous material remediation shall be done in accordance to requirements of the local jurisdiction, removed and disposed of legally, before proceeding with building renovations. Hazardous materials, or items suspected of containing hazardous materials, shall not be disturbed except under procedures specified elsewhere in the Contract Documents. The cost of Hazardous material remediation has been included in the final cost estimate.

1.13 CODE REVIEW, COMPLIANCE AND WAIVERS

Generally, restoration work for building repairs and replacement of roofing, windows and doors does not require code review or code upgrades. Areas of buildings that are expanded or altered are generally required to comply with the International Building Code (IBC), local code jurisdiction and accessibility codes outlined in the IBC and further described in the Americans with Disabilities Act (ADA).

Enforcement of these code requirements is subject to interpretation by the governing code official for any given project. Two areas within the building subject to code review and upgrades are the

Auditorium and Bathroom Addition.

During the 2022 Design Revisions, the Auditorium work was completely removed from the scope of work and our documents. However, if this work is eventually undertaken by the RBPC, the Auditorium alternation proposed would increase the occupant load by 3 persons. With the removal of the projector room, area designated as an Accessory equipment space in the IBC has become part of the auditorium

Assembly area. Assembly area has a much higher occupant load factor than the area in a projector room, increasing the overall occupant load. This would likely be subject to review by a code official.

Potential code upgrades, requiring a waiver if not provided, include the following:

1) An illuminated exit sign is required above relocated exit doors in the area where the projector room was removed. This has been added to the Construction Documents. Existing exit signs shall remain above exit doors on either side of the stage.

2) Exit doors next to the stage may be required to have egress hardware.

3) New wood paneling in area of old projector room, to match existing, is not a Class A rated material

(fire resistant) as required.

4) Fire Protection: Fire extinguisher(s) may be required. Additional fire protection may also be required, such as 2 layers of type-X gypsum board (for 1-hour rating) on the ceiling to protect wood roof construction, or an automatic sprinkler system.

5) Restroom alterations create two rooms in place of one. The addition of one restroom in a building not having accessible toilet rooms might be subject to code review and compliance with IBC and ADA requirements. If so, each restroom would need to be accessible with an accessible route into the building leading to the restrooms. In this case, the following code upgrades shall be waived by the COR.

a) One ADA accessible sink in each restroom.

b) One ADA accessible toilet in each restroom with grab bar.

c) Area for required wheelchair turning radius.

d) ADA accessible door hardware.

e) Accessible route from restrooms to ADA accessible exterior door.

f) Ramp with handrails from exterior door landing to parking level.

STRUCTURAL AND CIVIL ENGINEERING NARRATIVE

S01 STRUCTURAL DESIGN NARRATIVE

1.1 GENERAL

The subject buildings are two-story masonry bearing wall structures with concrete framed second-floors and wood-framed roof structures. The lateral force–resisting systems consist of masonry shear walls which receive loads from plywood roof diaphragms and concrete second floor diaphragms.

The existing structural condition of the buildings appears to be in good condition, with no significant visible cracking in concrete or masonry or moisture damage in wood members and decking.

The tenant requested a significant auditorium expansion which is not possible with the current construction budget. As presented to the RBPC during our site visit debrief meeting, we propose a smaller re-configuration which relocates the projector room to create an entry area and slightly increase the seating capacity. During the 2022 Design Revisions, the Auditorium work was completely removed from the scope of work and our documents.

As part of the Kitchen health and food safety upgrades, the exterior trash enclosure is being replaced and enlarged to be relocated away from the kitchen back service door.

C01 – CIVIL DESIGN NARRATIVE

1.1 GENERAL

The site and site grades are to generally remain as is. Existing site utilities are to remain undisturbed and all existing utilities and installations to remain shall be protected during construction.

1.2.1 STORM DRAINAGE GRADING

Based on input from the RBPC, the existing storm drainage is functioning adequately. The island and site are very flat, and no city storm drainage piping exists in this area. There are storm drainage inlets located within the center island of the parking lot, which drain vertically into deep holes that are reported to have been drilled 200-feet into the ground.

1.2.2 POTABLE WATER SERVICE

The existing water service piping is to be reused. The existing water tap sizes from the street are too small to provide adequate pressure to the buildings, however they have been supplemented by water tanks, pumps and pressure tanks for each building.

1.2.5 SANITARY SEWER PIPING

No City sanitary sewer service exists on the street or adjacent to the site. The site is serviced by a series of multi-chamber in-ground septic systems.

E01 ELECTRICAL DESIGN NARRATIVE

1.1 GENERAL DESCRIPTION

A. Main Electrical Service Upgrades: At the time of inspection, the building was in use. While some of the electrical equipment disconnects and circuit breakers were exercised to determine connected loads, the majority of the equipment was not exercised. It is clear that over time, equipment has been modified in ways that has left the equipment non-code compliant. In addition, the electrical equipment is near the end of its useful life. As a result, we recommend the replacement of all building mounted electrical branch panels and equipment disconnects that are being bypassed, missing enclosure parts and are currently non-code compliant. These pieces of equipment create a life safety issue that shall be remedied.

This does not include, however, the service transformer, main disconnect, transfer switch, generator or main distribution panels for each building. Those pieces of equipment will remain in service as is.

B. Electrical Upgrades: At the time of inspection, non-code compliant wiring and splices were discovered above accessible ceiling cavities and accessible attics. As a result, we recommend that all Non-Metallic Sheathed cable (NM, NMC and NMS) above accessible ceiling cavities be installed in conduit and all splices be installed in junction boxes. In addition, we recommend that all Non-Metallic Sheathed cable (NM, NMC and NMS) in accessible attics be installed in compliance with NEC 334.23 and all splices be installed in junction boxes.

Interior Lighting and Fans will be replaced in all rooms with ceiling grid replacement. The new fixtures will be LED and include emergency battery backup, as required.

C. Kitchen Upgrades: In addition to replacing HVAC equipment as discussed in the Mechanical

Narrative, all receptacles within the kitchen area will be replaced with GFCI protection in accordance to NEC 210.8 (B). This includes 120V single-phase receptacles, 50A or less and 208V three-phase receptacles, 100A or less.

D. Computer Lab Upgrades: A new raised floor shall be provided for the Computer Lab. As a result, new floorboxes with power and data shall be provided for student desks. In general, existing floorboxes will be utilized to provide power to new floorboxes. This will minimize the need for new branch circuits throughout the space.

E. HVAC Upgrades: Equipment replacements required by the HVAC [MECHANICAL] DESIGN

NARRATIVE shall have the required electrical upgrades. If new equipment is provided in the existing location, existing electrical infrastructure shall be utilized to minimize cost. If new equipment is provided in new location and replaces existing equipment, existing electrical infrastructure shall be spliced and extended to new equipment location, to minimize cost. If new equipment is not replacing existing equipment, such as exhaust fans, new branch circuits shall be provided for new equipment.
