should not necessarily be considered schematic designs of the space type. A detailed facility program generally provides sufficient information on which to base a preliminary construction cost estimate or planning exercise. Components of a facility program are given in Box 2.3.

Planning Alternatives

Planning alternatives should be developed after the requirements of the project are determined, should be based on the facility evaluation and program, and should take into account the sequence of construction or renovation activities. A number of preliminary planning alternatives should be developed, which

Facility Program Components

  1. Facility program summary. A facility program summary is a list of the spaces to be included in the proposed new and/or renovated laboratory facility, This list could be an extrapolation of the list of existing spaces; however, it should reflect the users' needs rather than the current spaces occupied. Alternative types and arrangements of space, which may lead to more efficient space allocations, should be considered. In addition, the benefits of standardization of similar use areas should also be recognized. These advantages are more fully discussed in the ''Design Considerations" section of Chapter 3.

  2. Categorization of space by type. The categorization of space by types (office, office support, laboratories, laboratory support, shared support, and so on) can aid in the calculation of total area requirements when area allocations are made for each space type. However, an alternative categorization may also be required when a suite comprising a collection of types of space is allocated to a particular research group.

  3. Identification of appropriate standards to use in estimating total area requirements. Appropriate standards to use in estimating area requirements can be current area allocations, allocations determined as a result of benchmarking, or industry standards.

  4. Determination of total area requirements. The net assignable square feet (NASF) equals the number of types of space multiplied by the area to be allocated for each type. This number will equal 50 percent to 70 percent of the gross square feet (GSF), depending on building type, size, and location.

  5. Identification of desirable space attributes. Desirable space attributes include adjacencies, services, furnishings, and so on.

  6. Identification of required space attributes. Required space attributes include temperature, humidity, lighting level, and so on.
