A complete construction estimate should include: a written scope of work defining the project and its boundaries; line-item costs organized by trade with labor hours/rates and material quantities/specifications separated; subcontractor scopes as solicited bids or clearly labeled allowances; general conditions (supervision, temporary facilities, cleanup); overhead and profit stated transparently; permit fees by permit type; a visible contingency line item with the percentage and basis explained; and an explicit list of exclusions — things that are not included. If any of these elements are missing, the estimate is incomplete and will produce change orders after work begins.
