END OF SECTION 5

SECTION 1 - PROJECT DESCRIPTION

A. SUMMARY

The project involves the design, replacement, and improvement of roof cover systems at the Charles

Bennett Federal Building 400 West Bay Street, Jacksonville, Florida. The existing roof cover is severely deteriorated. During Hurricane Irma, the roof was severely damaged. Moisture migration and entrapment at the roof cover is disrupting tenant operations as well as precluding satisfactory thermal performance of roof insulation materials. In addition, the roof cover does not meet government and industry standards for energy and environmental conservation by the roof surface.

The existing low-slope roof cover involves two (2) roof areas; Main building roof and penthouse roof both containing 36770 square feet. The existing low-slope roof cover consists of a multi-ply asphalt roofing membrane system with a gravel cover and board insulation over a second multi-ply asphalt membrane on top of lightweight insulating concrete on metal decking atop a steel structure. The roof assembly also involves metal flashing and parapet caps; internal rain leaders; and associated sealants. It is assumed that asbestos containing materials (ACMs) are not present. This will be confirmed via testing completed by the design-builder in the investigative phase of the project. A change order will be issued for the removal of any ACMs, if found.

The designer-builder shall design and construct appropriate repairs, replacements, and improvements of the low-slope roof cover, rainwater drainage systems, and joint sealant systems.

New low-slope roof membranes are limited to atactic polyproylene (APP) or styrene butadiene styrene (SBS) modified bitumen roofing systems. The surface of the roof membrane shall be highly reflective. New joint sealants are limited to silyl terminated polyether, silyl modified polyurethane, and standard polyurethane and silicone sealants. Section 4 of this statement of work provides additional requirements for these new systems and components.

This project requires construction and demolition (C&D) waste diversion plans, waste diversion monthly reports, and related documentation.

The Designer-Builder shall also provide a web-camera surveillance system to monitor on-site work progress on low-slope roofs through project completion.

In addition, the designer-builder shall provide a twenty-year (20-year), no-dollar-limit (NDL) warranty on all areas of low-slope roof replacements. The low-slope roof warranties shall include wind riders to cover damage caused by wind up to the design wind speed for the building location or up to 140 miles per hour, whichever is less.

B. PROJECT GOALS AND OBJECTIVES

1. Goals:

a. Provide new low-slope roof cover that is leak-free for a minimum of twenty (20) years.

b. Repair, upgrade or improve rainwater drainage systems on the roofs of the building as required to provide effective and efficient removal of water from the roofs.

c. Maximize the project's contributions to environmental sustainability.

d. Maximize the project's contributions to national energy security.

2. Basic Contract Requirements (Base Offer):

a. Remove all low-slope roof cover at the federal building and replace with new roof cover that includes multiple-ply modified bitumen membranes. The membranes shall have a highly-reflective surface. Embedded surface granules shall not be used to achieve reflectivity. New insulation shall meet the R-value recommendations of ASHRAE 90.1 or come as close to these recommendations as is possible without raising door and window sills, through-wall flashing, or similar components. Repair or improve roof slopes as required to prevent ponding of rainwater and to insure efficient flow of rainwater to roof drains. Provide ¼” per foot slopes where absent.

b. Remove and replace all flashings associated with roof covers. Replace existing metal flashings and wall caps with new aluminum and copper flashings, as appropriate. Lead flashing materials are prohibited. Replace non-metal flashings and pitch pans at roof penetrations with new reinforced, fluid-applied PMMA or similar fluid-applied flashing material. Fluid-applied flashings shall also be applied to the inside face of exterior walls surrounding the cooling towers, including under wall caps, in accordance with manufacturer’s recommendations.

c. Replace joint sealants associated with replaced roofing components and at exterior walls of the penthouse, including at expansion joints, parapet caps, and copings. New joint sealants are limited to silyl terminated polyether, silyl modified polyurethane, and standard polyurethane and silicone sealants.

d. Repair or replace all existing equipment supports that exhibit deterioration, non-conformance with manufacturer's recommendations, or non-conformance with NRCA recommendations. Raise existing supports where required to accommodate additional roof insulation and to meet NRCA recommendations. Install new curbs where required but missing. Any unneeded or abandoned equipment supports must be removed.

e. Replace all strainers on roof drains and improve drains as required to insure effective roof drainage and to prevent ponding and leaks at drains.

f. Remove and reinstall all electrical conduit, wiring and antennae on roof surfaces and associated components as required to accomplish roof work. Comply with UL, IEEE, and NEC requirements when reinstalling lightning protection. Conduit and wiring for security cameras can only be removed and reinstalled by Meridian Security System Incorporated personnel. The contractor is responsible for the cost for this work and must coordinate with Meridian Security System to accomplish it.

g. Provide new roof walk pads from roof access points to, around, and beneath all powered rooftop equipment.

h. After completion of roof work, rout out all roof drains for a distance of forty feet from the drain opening to remove all obstructions. After routing is completed, inspect the drain pipes with a fiberscope, borescope, or similar tool to the same distance. All inspections shall be recorded on video. Also provide a report descriptive of findings.

i. Comply with LEED requirements for Sustainable Sites, Energy and Atmosphere, Materials and Resources, and Indoor Environmental Quality credits as applicable to the project. Also comply with LEED Pilot Credit 54: Avoidance of Chemicals of Concern, Option 2.

j. Provide a web-camera surveillance system to monitor on-site work progress through project completion

k. To minimize Contractor Security requirements, contractor forces should access the roof work area without entering the Federal building via exterior lifts, as practicable. Use of interior elevators for construction activities will be minimal.

l. New materials, tools and demo wastes should be taken to and from the roof work areas via exterior means, as practicable. Use of interior elevators for construction activities will be minimal. Reasonable Staging area(s) will be provided by the Government at the rear of the facility for the Contractor’s use.
