Programming Methodology Staff net space requirements were derived from the growth projections and existing standards utilized -by Indian River County and many other counties of similar size throughout the state of Florida. Support spaces were tested in diagrammatic form to establish the area (net square foot) requirements for these spaces. Other key areas such as the conference center and food service (breakroom) were developed in diagrammatic form allowing for equipment, staff and circulation requirements. Common amenities were developed by a process similar to that used for other key areas, utilizing diagrams presented to and reviewed by the County. The diagram which best represented the program requirements established the net square foot allocation in the program. Building support spaces were sized by establishing criteria for population count and mix for restroom facilities, capacity, size and level of redundancy for machinery and equipment spaces and by applying historical knowledge of other projects of similar size and complexity for maintenance areas. Circulation, the net to usable (circulation) area factor was derived by applying historical knowledge of other projects of similar size and complexity. This factor was adjusted or deleted where internal circulation was already accounted for in the diagram for certain spaces. The factor used was 1.35 x net SF. Usable to gross area factor was derived by applying historical knowledge of other projects of similar size and complexity. This factor was reasonably constant throughout the program spaces. The factor used was 1.2 x department net equals GSF. This factor results in a building that is approximately 83.3% efficient versus the existing building which is approximately 69.9% efficient. Conclusions Staff Projections (both buildings): :I As of calendar year 1998, the county staff count is 280; 264 will be housed in the administrative building while 16 will be located in the purchasing building. o As of calendar year 2001, move -in, the county staff count is projected to be 339; 319 will be housed in this administrative building while 20 will be located in the purchasing building. ZI As of calendar year 2010, the county staff count is projected to be 401; 378 will be housed in the administrative building while 23 will be located in the purchasing building. Building Area: The new Administrative Office and Purchasing/Buildings and Grounds/Probation Facility will contain a County Commission Chamber and office space for each Commissioner, Supervisor of Elections, Property Appraiser, Clerk of Circuit Courts, Clerk to the BOCC, County Administrator, and County Attorney. Office space is also provided for the departments of General Services, Public Works, Emergency Services, Management and Budget, Risk Management, Community Development (Planning and Building Divisions), Personnel, Utility Services, Data Processing, as well as other County functions. Common amenities and building support spaces comprise the remainder of the building. The Purchasing Department, Buildings and Grounds and Probation Facility will house space for these departments, as well as file storage space for other departments. The total gross square footage of the two components, the Administrative Building (163,980 SF) and the Purchasing/Buildings and Grounds/Probation Building (27,985 SF) is 191,965 GSF. Included in the total gross square footage is an allowance of approximately 8% for mechanical/electrical spaces, 35% for departmental circulation and 20% for building items such as building skin, elevators, stairs, interior columns, etc. Master Planning SCP looked at many options for master planning the new facilities. Initially, 8 to 10 scenarios were studied for positioning the buildings on the site. Vehicular and pedestrian traffic buildings "front door" as approached by vehicles and pedestrians wconsiderations were studied. Flexibility and expansion capabilities were also consideredas critical to the. The establishment of the site plan. Of the many scenarios studied, SCP presented 3 of the most viable solutions to the County for review in early November. The final master plan presented in this document is the result of the comments received at the November meeting and the subsequent design effort. The proposal seeks to create a new civic neighborhood of public buildings by placing the new county administration building between 26h and 27"' Streets north of the existing county administration building, with access from the north and the south. In the first phase public access is provided to the main entrance of the building on the south from 18' avenue, linking the new building's entrance to the existing building's entrance. This approach will serve both as public and ceremonial access for citizens coming to seek services in the building as well as those visiting the commission chambers. Surface parking is proposed immediately to the west of the N. MARCH 169 1999 -81- BOOK i0C' PAGE 696 I
