Dear Ms. Oiliberti:

This proposal for sidditional design services includes work requested as part of as part of the review of 100% CD. submission and subsequent requests for revisions received on June 18, 199g

Per SHCA's review of the Mayor’s Office of Emergency Management’s comments to the 100% C.D. drawing issuance (04-06.98) which were received 04-22-98 and 04-28-98, the OEM comments request severai revisions which are changes in scope. SHCA has reviewed the scope of wexk referenced in SHCA’s 10-24-97 agreement with Silverstein Prc^rties, Ine. including all scope and program intormation referenced in the agreement, all correspondence from Silverstein/DCAS/OEM and all meeiLng conferKoce reports to date, SHCA also cannot find any reference in these documents that require the design of a “hurricane wall” that can resist Category 4 hurricane winds with wind prasures as indicated m OEM’s 04-22-98 conjincnts, SHCA also cannot find any record requesting the extension of the scope of the “hurricane wall” beyond the exterior wall which will hilly envelope the entire Emergency Operations Center and support spaces on the southern portion of the 23'“ Floor per OEM’s marked-up plan received 04-28-98.

In previous discussions widi OEM, OEM expressed a need to have a protective wall in front of the exterior wall of the Emergency Operations Center to protect its occupants from broken glass and rain in the event of a hurricane (of an unspecified magnitude). In a SHCA Conference Report dated 11-17- 98, item 3.4 records agreement that the exterior wall glazing shall be blocked-off by a lightweight drywall partition designed to address the OEM security and hurricane wind load cancer ns.

In addition, the Department of Citywide Administrative Services (DCAS) letto dated June 18, 1998 to Silverstein Properties, Inc., DCAS requests several additional revisions which arc changes in scope iiicluciing further revisions to Ute ‘protective wall’. These revisions in scope will require the issuance of an addendum to the approved 100% C.D. drawings and specificatiors previously issued for bid. Also, the revised C.D set will require re-submission for review and approval to the Pon Audiority of NY & NJ.

Swankc Hayden Connell & Partners LLP (SHCA) wishes to submit its p’opcsal for ai'chitectural and cngineei ing services in connection with the above referenced revised design work as follows:
