Many contractors use a combination of spreadsheets, templates, and specialized estimating software to build a public bid package, with the choice often depending on the complexity of the project and the contractor's internal processes. For federal projects, the FAR outlines specific requirements, but for state and local projects, the process is driven by the state's procurement code and the specific portal's vendor guide. Specialized estimating software can integrate takeoff calculations directly into the pricing, reducing manual data entry and the risk of arithmetic errors that can occur when transferring figures from a spreadsheet to a bid form.
These tools often have features for managing different cost elements, tracking labor rates, material costs, and equipment usage, and they can help with version control as you refine your bid. They also typically allow for easier incorporation of changes from addenda, which is crucial for maintaining a compliant and accurate bid. Bond paperwork and other required documents can be tracked through project management features within some of these estimating systems, or through a dedicated document management system. For construction contracts above the simplified acquisition threshold but not exceeding an amount for which the Miller Act applies, the contracting officer selects two or more alternative payment protections, such as a payment bond, an irrevocable letter of credit or a tripartite escrow agreement. For federal construction contracts, the Miller Act requires performance and payment bonds for any contract exceeding a certain amount.
