Subcontractor Invitation to Bid Letter

What a good one includes

• A clear project overview including the location, type of residential construction, and overall estimated project schedule.
• A detailed scope of work specific to the targeted trade so the subcontractor knows exactly what parts of the project they are pricing.
• A comprehensive list of bid documents, including architectural drawings, engineering plans, and specifications, along with instructions on how to access them.
• A strict submission deadline with a specified date, time, and preferred method of delivery.
• Mandatory compliance and qualification requirements, such as general liability insurance minimums, worker's compensation, and licensing details.
• A designated point of contact with direct phone and email information for any Request for Information (RFI) questions.
• A standardized bid form or breakdown structure to ensure all received quotes are formatted identically for easy comparison.

Common mistakes to avoid

• Sending vague project scopes that force subcontractors to make assumptions, leading to inaccurate pricing or unexpected change orders later.
• Omitting clear deadlines and submission formats, which results in scattered, late bids that delay the overall project estimation process.
• Failing to provide easy access to complete blueprints, specifications, and site condition reports needed for precise calculations.
• Neglecting to mention mandatory licensing and insurance requirements upfront, resulting in wasted time evaluating unqualified trades.
