Note any ambiguities, missing details, or conflicts between drawings. Submit RFIs early. Assumptions kill profit margins. ### Step 2: Get Subcontractor Quotes Send bid packages to 3+ subs per trade. Include plan pages, specs, and your schedule. Set a firm deadline 5-7 days before your bid is due. Late sub quotes are the #1 cause of rushed, inaccurate bids. ### Step 3: Build Your Estimate Compile material takeoffs, labor hours, equipment costs, and sub quotes. Organize by CSI division for commercial or by phase for residential. Double-check quantities against plans. A 5% takeoff error on a $200K job is $10,000. ### Step 4: Add Overhead, Profit, and Contingency General conditions (supervision, temp facilities, insurance) typically run 8-15% of hard costs. Add your profit margin (5-12% for competitive commercial, 15-25% for negotiated work). Include 3-5% contingency for unknowns. ### Step 5: Submit and Follow Up Submit your bid package with the required forms, insurance certs, and bond letter. Follow up 2-3 days after the deadline to confirm receipt and ask about the timeline. A professional follow-up shows you want the work. ## Average Construction Project Costs to Guide Your Bids Use these benchmarks as starting points. Actual costs vary by region, materials, and job complexity. | Job Type | Material Cost | Labor Cost | Total Range | | --- | --- | --- | --- | | Custom home build (2,500 sq ft) | $125,000 – $250,000 | $100,000 – $175,000 | $250,000 – $450,000 | | Commercial tenant improvement | $40 – $80/sq ft | $30 – $60/sq ft | $80 – $150/sq ft | | Multi-family (per unit) | $80,000 – $150,000 | $60,000 – $100,000 | $150,000 – $275,000 | | Restaurant buildout (2,000 sq ft) | $80,000 – $150,000 | $60,000 – $120,000 | $160,000 – $300,000 | | Warehouse/industrial (10,000 sq ft) | $50 – $100/sq ft | $30 – $60/sq ft | $80 – $160/sq ft | | Site development (1 acre) | $30,000 – $80,000 | $20,000 – $50,000 | $60,000 – $150,000 | ## Bidding Best Practices for Construction Contractors ### 1. Never bid from incomplete documents If the plans are missing structural details, MEP specs, or finish schedules, submit RFIs before bidding. Assumptions become disputes. If the owner will not clarify, add contingency and note your assumptions explicitly. ### 2. Get at least 3 sub quotes per trade One quote is a guess. Two quotes show a range. Three quotes give you confidence in your number. The lowest sub is not always the best. Factor in their track record, insurance, and ability to meet your schedule. ### 3. Include clear exclusions State what is NOT in your bid. Furniture, low-voltage, landscaping, permits, owner-furnished items. Spell them out. Unclear exclusions lead to scope disputes that eat your profit. ### 4. Build in material escalation protection Lumber, steel, and copper prices swing 10-30% annually. For bids valid 60-90 days, include a material escalation clause or add 3-5% to cover price movement. The alternative is eating the difference. ### 5. Submit early, not at the deadline Early submission shows organization and confidence. Last-minute bids suggest desperation or disorganization. For public bids, arriving early avoids the panic of traffic, printer issues, or upload failures. ### 6. Track your bid-to-win ratio If you are winning less than 1 in 5 bids, you may be too high. Winning more than 1 in 3? You are likely leaving money on the table. Adjust your markup based on data, not gut feeling. ## Frequently Asked Questions ### What’s the difference between an estimate and a bid? An estimate is an internal cost projection for planning. A bid is a formal price submission to a client or GC. Bids typically include a fixed price, schedule, qualifications, and bond (for commercial). Your internal estimate informs your bid price. ### How long should a construction bid be valid? 30 days for residential, 60-90 days for commercial. Include a material escalation clause for bids over 60 days. Some public projects require 90-120 day validity. Price that risk into your contingency. ### Should I include a bond in my bid? Commercial and public projects usually require bid bonds (1-5% of bid price) and performance bonds (100% of contract). Build the bond cost (1-3% of the contract value) into your overhead. Residential rarely requires bonding. ### Should I include alternates in a bid? Yes, when the spec allows. Alternates give the owner pricing options (upgrade finishes, add scope, substitute materials) without rebidding. Price each alternate as a standalone add or deduct and note how it affects your schedule. ### How do I win more construction bids? Be the most complete and professional submission. Include all required forms, reference similar projects, provide a realistic schedule, and submit on time. Follow up after submission. The lowest price does not always win. Reliability and presentation matter.
