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.
