Roof Replacement Amendment Scope of Work

Design Build Criteria

1. Summary

1.1. GSA has opted to amend a full roof replacement into the vegetative roof installation at the Green Federal Building. All prior requirements of the vegetative roof remain intact, with the exception of roof coating requirements for these roof areas. The new roof installation shall supercede the roof coating requirements to provide the same required 20 year waterproof warranty. The existing Green building roof and penthouse level consists of approximately 62,660 square feet of a Built-Up-Roof system with lightweight insulating concrete and the remaining 6,140 square feet consists of a BUR system on concrete deck. The roof is divided in to two areas, the penthouse/mechanical yard and the outer ring of the roof. The penthouse/mechanical yard area consists of over 50% of the area at this level. It is heavily occupied by operating mechanical equipment. The surface of this portion of the roof is worn due to maintenance traffic. The outer ring is just under 50% of the overall roof area and is a relatively open roof plan. This entire roof area shall be demolished, including all abandoned curbs, dunnage and other stub-up mounts for equipment that is no longer there. There are a few select active pieces of equipment that will remain located on this roof. A new inverted roofing membrane assembly (IRMA) shall be installed on these roof areas beneath the vegetative roof already specified for this project.

2. Project Description

2.1. Project Goals

Increase the insulation value of the roof.

Provide a new, waterproof IRMA roof as the base for the vegetative roofing system previously specified.

2.2. Reference Materials

2.2.1. Roofing design and installation must follow the recommendations of the

National Roofing Contractors Association (NRCA) as contained in the NRCA Roofing and Waterproofing Manual.

2.2.2. ASTM E2400-06 Standard Guide for Selection, Installation, and Maintenance of Plants for Green Roof Systems.

2.2.3. ASTM E2397-05 Standard Practice for Determination of Dead Loads and Live Loads associated with Green Roof Systems

2.2.4. EPA Technical Guidance on Implementing Section 438 of the Energy Independence and Security Act, when available.

2.2.5. GSA P100

3. General Requirements

3.1. Performance Objectives

3.1.1. Thermal Performance

Roofing replacement designs should target a composite insulation value goal of R- 50 including insulation and a calculated value of the soils and vegetative overburden. (It is recognized that the insulating qualities of the soils is subject to change based on moisture content etc.) A minimum requirement of R-30 must be achieved on this project. Existing closed cell insulation in good condition without excessive moisture or structural degradation may be reused. The design shall included consideration for existing penetrations and parapets.

3.1.2. Drainage

All drains shall be tri-level design with primary drainage at the membrane to prevent ponding, secondary drainage via through the insulation and vegetative media and tertiary overflow above the level of the vegetation. Access to the drain for maintenance and cleanout must be provided

3.1.3. Water Test

The new roof shall be water tested prior to the installation of the vegetative roof system for a minimum of 24 hours. This shall be witness by GSA and signed off on prior to installation of the vegetation.

4. Scope of Services

4.1. Design Stage

4.1.1. Survey

4.1.1.1. The A/E is to visit the site, consult with the Building Manager concerning the nature of the roof problems, examine the roof, taking non-destructive samples as necessary, and examine any existing record construction documents and/or shop drawings.

4.1.1.2. The structural capacity of the existing deck for the vegetative roof must be assessed in order that the roof will support the extra dead load of the designed planting media, other components, and detained water. All of these loads are exclusive of applicable snow loads. Refer to Vegetative Roof portion of the scope of work (Volume 2 Page 3.3-2) for other loading requirements.

4.1.1.3. Upon accessing and analyzing the data compiled via the above-described process, the A/E is to produce a narrative that validates the type of roof and installation that the A/E has selected to meet the project objectives and maximize the roof membrane warranty.

4.1.2. Design

4.1.2.1. The following requirements must be included in the new IRMA roof.

4.1.2.1.1. Minimum of R-30, with a goal of R-50.

4.1.2.1.2. Use Waterproof Extruded Polystyrene Insulation with a flame spread rating of 15 or better.

4.1.2.1.3. Phasing plan which includes but is not limited to

4.1.2.1.3.1. demolition,

4.1.2.1.3.2. drying of existing lightweight concrete deck if reused,

4.1.2.1.3.3. new installation

4.1.2.1.4. Leak Detection system for vegetative roof (see scope of work for Vegetative portion (Volume 2 Page 3.3-2).

4.2. Construction

4.2.1. Remove existing roof material to arrive at a suitable base for installation of the new vegetative roof. The contractor shall be responsible for the suitability of the substrate surface to accept the vegetative roof.

4.2.2. Provide a new roof installation including but not limited to roof waterproofing and closed-cell waterproof insulation material. The roof waterproofing must be able to withstand ponding water, survive expected deflection or expansion, resist chemical action of acid rain and fertilizers, and be resistant to root penetration. The design shall utilize an engineered soil medium and plants as ballast. Compatibility between the engineered soil medium, plants, and the roofing system below must be demonstrated to avoid negation of any manufacturer warranties. The roof warranty must include the planted roof system and all components.

4.2.3. Any excess water that is not contained by the engineered soil medium shall drain positively to the existing roof drains. Utilize composite drainage mats to assist with drainage. The selection of the roof waterproofing system must support the ease of leak detection and not allow water to travel under the waterproofing.

4.3. Warranty

4.3.1. A planted roof is a complete system and the waterproofing warranty shall include all components of the waterproofing and planted roof. The waterproofing system shall be warranted for a minimum of 20 years covering wind damage for up to 60 mph.

4.3.2. A plant warranty against disease and death shall extend for 2 years from date of planting. Replant areas that fail to provide a uniform cover of plants, with specified materials, until the Owner accepts all affected areas.

4.3.3. Provide for all new roofs a single source responsibility warranty, including removal and replacement of the overburden and the growing media.

4.3.4. The Design Builder shall provide for a period of two years, maintenance of the vegetative roof including but not limited to the insulation, membrane, soil medium and the planting.

0.0 PURPOSE

GSA will require the Contractor to utilize an Enterprise electronic Project Management (e-PM) system on this project. GSA’s goal is to implement this state-of-the art technology to reduce administrative and overhead costs, eliminate redundancies, and institute a collaboration tool to ensure better accountability among all project team members. This technology will provide up-to-date information, encourage disciplined methods for monitoring progress, ensure better communication regarding changes, provide improved documentation, and enable PBS executives to have real-time access to status of projects.

1.0 DEFINITION

e-PM is defined as an internet-based information and project communication system that allows the entire project team to collaborate in a centralized and secured repository. All project-specific correspondence, workflow processes, and documentation will be stored and routed within the ePM system.

2.0 PROJECT DOCUMENTATION

The Contractor is required to timely and accurately post, review, respond, and collaborate with other team members using the following features and/or workflow processes within the ePM system:

Project Team Directory – Contractor shall provide an updated directory of contact information for all companies, subcontractors and project team members who are engaged on this project.
