• though these ceilings must be replaced, the height is greater than necessary for single -story office occupancy, and less than required for two-story use in most of the facility. • Toilet room cores exist in each of the anchor stores and at the south end of the central building. Only the central restrooms are handicap accessible, however. All toilet rooms and fixtures are dated and unsuitable for a modern facility. Demolition and reconfiguration of these rooms will be necessary. It will also be necessary to cut concrete floors to install new water and sanitation lines. Architectural Summary: Even though the site is large and contains considerable parking space, the distribution is one-sided. As a result, access to the building is also one-sided and not well suited to easy or balanced employee or visitor access. Little of the "architecture" is salvageable for a conversion to offices except the building structure and shell. The exterior walls will require modification to provide windows and an updated general appearance appropriate for a County Administration Facility. Even so, the height of the building and large depth of lease spaces do not offer optimal space for refit to office use. The efficiency of a Mall retrofitted for use as an Administrative Facility will be considerably less than if designed as a new facility. The following items would be necessary to convert this building into usable office space: • A total demolition of all interior elements as described above. • A roof replacement to meet hurricane and energy criteria. • Insulation of the exterior precast concrete walls to meet energy and sound attenuation requirements. • Totally new HVAC, plumbing, and electrical systems. • Cutting of the exterior precast concrete panels for windows to allow natural light into an office environment. • A major effort to light, landscape, and enter/exit the site. • Provide an upgraded or larger sanitation system. • Additional acoustical attenuation to negate the sound of pass- ing trains. • Dampproofing of the exterior wall will be required to eliminate the possibility of water infiltration which can cause poor air quality. • Site drainage must be increased and more retention is required for both the Indian River Farms and St. John's Water Management Districts. Both of these requirements will reduce the total number of parking spaces on-site. It is easy to expect the cost for conversion to appropriate office space to cost similar to that of building a new facility. We estimate that a new facility will cost approximately $115.00/s.f to build, exclusive of site costs; and we expect the conversion of this mall to be less than a $10.00/s.f. difference, or about $105.00/s.f. In addition, the new facility will be appropriately designed as a County Administration Facility, while this mall will always be a less - than -optimum converted mall. We estimate site costs to be simi- lar in both locations, approximately $750,000. July 28, 1998 35 0 BOOK 106 PACE 408
