SHCA Project No. 5576 CC & CD
Dear Ms. Gilibetti;
This proposal for additional design services includes work requested as part of as part of the review of
100% C.D. submission and subscquart requests for revisions received on June 18, 1998.
Per SHCA’s review of tbe 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
several revisions which are changes in scope. SHCA has reviewed the scope of work referenced in
SHCA's 10-24-97 agreement with Silverstein Properties, Inc. including all scope and program
information referenced in the agreement, all correspondence from Silverstein/DCAS/OEM and all
meeting conference reports to date. SHCA also cannot find any reference in these documents that
require the design of a “hurricane waif that can resist Category 4 hurricane winds with wind pressures
as indicated in OEM’s 04-22-98 comments. SHCA also cannot find any record requesting the
extension of the scope of the “hurricane waif’ beyond the exterior wall which will fully envelope the
entire Emergency (Relations Center and support spaces on fee southern portion of the 23'® Floor per
OEM’s marked-up plan received 04-28-98.
In previous discussions with OEM, OEM expressed a need to have a protective wall in front of the
exterior wall of die Emergency Operations Center to protect its occupants from broken glass and rain
in die 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 concerns.
In addition, the Department of Citywide Administrative Services (DCAS) letter dated June 18,1998 to
Silverstein Properties, Inc., DCAS requests several additional revisions which are changes in scope
including further revisions to the ‘protective wall’. These revisions in scope will require fee issuance
of an addendum to the approved 100% C.D. drawings and specifications previously issued for bid.
Also, the revised C.D. set will require re-submission for review and approval to the Port Authority of
NY & NJ.
Swanke Hayden Connell & Partners LLP (SHCA) wishes to submit its proposal for architectural and
engineering services in connection with the above referenced revised design work as follows:
