Net D, in the context of the construction industry, refers to the "net deliverable" square footage or area of a constructed property. It applies to the actual usable space that remains after the subtraction of communal areas such as shared hallways, staircases, and residential utilities from the gross square footage. In commercial real estate, it typically excludes areas reserved for mechanical systems, structural elements, elevator shafts, and similar components. This figure is critical as it impacts the leasing or selling value of a property and also informs space allocation, cost assessment, and planning considerations during a construction project. Therefore, understanding Net D is key to optimizing building layouts and the planning of space allocations within any construction project.

A G703 is a continuation sheet used in the construction industry. It's part of the AIA (American Institute of Architects) document set for contract documents. The G703 form includes a schedule of values listing portions of the work, scheduled values, work completed, materials stored, total completed and stored, percentage of work completed, balance to finish, and the amount of change orders. Hence, it is primarily used for breaking down the contract sum into portions of work in accordance with a schedule of values prepared by the contractor. It provides a running total of completed work and can be updated as work progresses.

Double-entry accounting is a system used extensively in the construction industry, where every financial transaction has equal and opposite effects in at least two different accounts. The objective is to ensure the sum of all debits always equals the sum of all credits, thereby maintaining balance in the books. For example, if a construction company purchases building materials, it records the transaction as a debit in the inventory account but a credit in the cash account. This system allows for easier financial analysis, error tracing, and fair representation of a company’s financial position. This method also manages the complexity of financial transactions in the construction industry, increasing financial reliability and providing valuable insights on company performance.
