account for the inflation in construction costs over time. This would bring the cost to about $258/S.F. in current dollars for a custom-designed public restroom. This figure compares favorably with costs that staff has solicited from manufacturers for prefabricated structures. As an example, the cost provided by Romtec Manufacturing, Inc. for its standard design structure that meets the City's program is approximately $260/S.F. This cost is for a "turn key" restroom, which includes the cost of all materials and factory construction, delivery to the site, preparation of a receiving slab and finishing trim; however, it does not include upgraded plumbing fixtures or building infrastructure. Design. Architectural and engineering design fees for the preparation of construction documents (this applies primarily to a custom designed structure) may be as much as $35,000 to $45,000. This is approximately 16% to 20% of the overall construction cost for the facility, and is typical for small projects of this type. Design of a manufactured structure is usually borne by the manufacturer; however, site layout and infrastructure design are the owner's responsibility, and therefore, some design cost (perhaps as much as $10,000 to $15,000), would need to be budgeted to accomplish this work. Infrastructure. As mentioned earlier, nearby utilities are available along W. Angela Street to service the proposed building. The cost of providing the actual services - both sewer and water, has been estimated at approximately $14,050. This figure does not, however, include connection fees. The City's Building Division estimates the one-time sewer connection fee (DSRSD) at roughly $13,050, and the City sewer connection fee at $660. It is anticipated that a minimum 3A" size water meter would be required to service the building. Fees for a meter of this size are currently $20,605 (City and Zone 7 fees combined). The total estimated infrastructure cost - both service and fees, is projected at $48,365. This figure must be budgeted as a minimum for either type of building (custom designed or manufactured). DISCUSSION Both City staff and the design consultant believe that an attractive, functional, and maintainable public restroom building can be provided either through custom design and construction, or the purchase ora manufactured building. Furthermore, the difference in operating costs and long- term maintenance or replacement costs between the two (2) building types is negligible. There is a general impression that prefabricated buildings are far less expensive than equally sized custom designed structures. To the extent that prefabricated structures eliminate the need for original architectural design fees and utilize a cadre of standard materials in construction, this is true. By the time one considers the costs associated with delivery to the site, foundation construction and utility connection, set-up and detailing, however, the overall costs between the two building types are commensurate. As a result, cost alone should not be the determining factor for selecting the building type for this highly visible location. The advantages of a custom designed structure would allow the City the freedom and flexibility to develop a building of its choice - both materially and aesthetically.
