This letter serves to document wind design pressures for roof cladding at the upper roof only in accordance with ASCE 7-98' based on the building parameters provided, and establish attachment requirements for the proposed Soprema roof assembly to meet said pressures. Note: The Project Information Form indicates the project is not eligible for a wind warranty rider. 1. DESIGN PRESSURES: The following parameters are set forth in the referenced documents. Design Parameter Value Source Max. Roof Height: 181 ft From PIF Parapet Height: > 3 ft From PIF Building Exposure: C From PIF Category: II Assumed Importance Factor: 1.0 Assumed Wind Speed: 140 mph From ASCE 7-98 map Designing for: Roof Cladding Tributary Area: < 10 ft2 Area per fastener Int.

Re: Atlantic View Condominiums February 21, 2005 Page 2 of 3 Table 1: Design Pressures, ASCE 7-98 Pressure Zone Design Pressures (psf) - Roof Cladding Upper Roof Zone 1 (field): -113.4 Zone 2 (perimeters): -177.9 Zone 3 (corners): See Zone 2* Zone 2/3 Dimension: Min. 10.5 ft Notes: 1. Perimeter and corner pressure zones are those within the lesser of 40% of the height or 10% of the minimum building width, but not less than 3 feet, and not less the Soprema requirements. 2. *It is reported that a parapet wall > 3 ft exists on the upper roof. ASCE 7-98 specifies treatment of Zone 3 as Zone 2 if such a wall exists. If no such wall exists, reevaluation is required. 2. PROPOSED ROOF SYSTEM: It is understood the following assembly is under consideration: • Roof Deck: Existing lightweight insulating concrete cast over existing concrete deck • Base Membrane: Soprafix[F] mechanically attached with Tri-Fix Fasteners • Cap Membrane: Sopralene Flam 180 FR GR, heat welded. 3.- PERFORMANCE DATA: LABORATORY TESTING: The proposed roof system has been tested for wind uplift resistance in accordance with FM Standard 4470 / TAS 114(]). Review of data yields a base membrane attachment value of 214 Ibf per fastener. Applying a 2 to 1 margin of safety provides a laboratory design value of 107 Ibf per fastener. FIELD TESTING: Protech Products field report dated 01/01/05 documents withdrawal resistance testing of the Tri-Fix Fasteners installed in the existing roof deck at the upper roof. Statistical analysis of the data in accordance with TAS 105 yields a Minimum Characteristic Resistance Force (MCRF) of 182 lbf. The existing deck at the upper roof is suitable to receive the Tri-Fix Fasteners while maintaining the above noted design value (107 Ibf). 4. ATTACHMENT REQUIREMENTS': Table 2 provides minimum base membrane attachment requirements to meet the design pressures in Table 1. Attachment is based on a design value of 107 Ibf per fastener. I Determined in accordance with procedures published in FBC PAS 117.

The information herein relates solely to the upper roof at the project. ERD's scope excludes any work at the lower roof. B. The analysis herein relates solely the new roof cladding to be installed atop the existing roof deck. ERD does not purport to address wind loading or adequacy of the existing LWIC or structural concrete roof decks, perimeter edge terminations, flashings or rooftop equipment. C. Tri-Fix Fasteners shall be installed in strict accordance with published installation instructions, using the correct angle of installation for each of the three nails. D. The laps in the Soprafix[F] base membrane, as well as the cover -strips in center rows, shall be heat -welded in accordance with Soprema installation instructions, fully encapsulating the fasteners within the lap or beneath the cover strip. 6. CONCLUSIONS: The proposed roof system outlined in Section 2, when attached in accordance with Section 4, meets the wind load requirements of FBC Chapter 16 / ASCE 7-98, provided the applicable comments in Section 5 are fulfilled.
