Board Order to Approve
Issuance of a Change Order for
Merrithew Memorial Hospital Replacement Project
Bid Package No. 3
III. REASONS FOR RECOMMENDATIONS
Change Order No.126 will provide for the following:
Proposed Change Order No. 555-3`d Floor Special Use Areas Revisions $42,925.00
Per previous agreements with OSHPD, contract drawings depicted the special use areas larger than
the code allowed 5000 sq. feet. Recent OSHPD interpretations have overruled this prior agreement.
As a result, several areas had to be cordoned off with double egress doors and partitions in order to
comply with sq. foot restriction. In addition, smoke dampers had to be added when ducts penetrated
the occupancy separations.
Proposed Change Order No. 582-Chilled Water Line to Lab $53,425.00
In order to leverage existing utility services and as previously mentioned in prior Board Orders, the
Owner has requested that the new lab building utilize the existing hospital's central plant for chilled
water and electrical service. To avoid disturbing newly completed site work, the Owner deemed it
prudent to install the new cooling lines in conjunction with the surrounding underground site
development. The scope of this additional work includes the installation of(2) 165' lengths of pre-
insulated cooling pipe,from the chiller room to just outside the hospital's limits of work
Proposed Change Order No. 608-Change Crisis, Geriatrics and Psych to I-3 Occupancy $31,303.00
Based on previous Owner requested design changes, several areas of the hospital were revised to
accommodate locked down security areas. Code mandates that when a patient's personal liberties are
restrained — as they would be in the above areas — no combustible flooring materials may be used.
Since these areas receive carpet and vinyl tile, an alternate means of fire protection must be provided.
This results in the upgrade of the sprinkler system classification in these areas from light to ordinary
hazard. The classification upgrade was accomplished by the addition of sprinkler mains and sprinkler
heads.
Proposed Change Order No. 678-Added Ductwork and Exhaust Fan at Emergency Generators $27,400.00
During preliminary testing of the Emergency Generators, enough heat was produced to discharge the
fire sprinklers in the rear of the generator room. To reduce the temperature in the room, the
mechanical engineer directed the installation of additional ductwork and an exhaust fan.
Proposed Change Order No.702-Added Exit Signs Per OSHPD Review $52,218.00
The contract documents depicted exit signs at various locations throughout the building. Code
mandates that "When two or more exits are required from a room or area, exit signs shall be installed
at the required exits from the room or area and where otherwise necessary to clearly indicate the
direction of egress." During field review, OSHPD noted that the corridor exiting signage did not
comply with the above criteria. As a result, numerous exit signs were installed throughout the
building.
The new guaranteed maximum cost will exceed the total estimated cost stated in the construction contract agreement
approved by the Board on February 7, 1995. The new guaranteed maximum cost will total $48,305,069.00.
