Most projects require a set of basic services. They are as follows: preliminary, or schematic, design; design development; preparation of construction documents (drawings and specifications); assistance in the bidding or negotiation process, and the administration of the agreement between you and your builder or contractor, if needed. Some projects will require other services, such as pre-design work, which includes budgeting and financing packages, as well as planning and zoning applications. Projects may also include special cost or energy analyses, models and tenant-related design.
