How To Bid a Job as a Subcontractor
Bidding on a job as a sobcontractor is great chance to secure the projects and grow the business. So, here is a quick way to do this.
Pre-Bid Preparation
Before diving into pricing, proper preparation is essential. Start by reading the project scope thoroughly. Know every detail of what the job entails. Missing even a small part of the requirements can cost you money and reputation.
Next, gather all required documents including blueprints, addenda, and specifications. Organize these documents so you can reference them easily throughout the bidding process. If possible, visit the job site to get a feel for site access, working conditions, and any potential obstacles.
Finding Bid Opportunities
To win more jobs, you need to consistently find new opportunities. Use online bid portals like BidClerk, Dodge Data, and Buildertrend to discover active projects. Build relationships with general contractors to get on their preferred subcontractor lists.
Often, repeat business and word-of-mouth referrals come from showing up and doing good work consistently. Networking at trade shows, industry meetups, and even on-site visits can also lead to new projects.
Analyzing the Project Documents
Proper analysis of project documents separates the successful subcontractor from the one who underbids and loses money. Start by reviewing the blueprints and specifications carefully. Focus on your trade but also understand how your work interacts with other scopes.
Look for risk areas like incomplete drawings or undefined materials. Clearly define your scope in the bid to avoid misunderstandings and scope creep later.
Estimating Costs Accurately
Your bid is only as good as your numbers. Begin with labor—calculate how many hours the job will take and multiply that by the appropriate wage rates. Then add material costs, using up-to-date prices from your suppliers.
Don’t forget to factor in equipment rentals, overhead expenses, and insurance. Finally, include your profit markup. Be realistic but competitive. A typical markup ranges from 10–20%, depending on the project size and risk.
Creating a Competitive Bid
To stand out, your bid must strike a balance between price and value. Avoid the trap of lowballing just to win the job that often leads to lost profits or poor-quality work. Instead, showcase your strengths in your proposal. Highlight your experience, certifications, past performance, and any value-added services you offer.
Format your bid clearly and professionally, using bullet points or tables where necessary to improve readability.
Submitting Your Bid
Before sending your bid, double-check all calculations and review the documents for accuracy. Follow the general contractor’s submission guidelines carefully. Failure to meet instructions could disqualify you. Make sure to submit by the deadline. Late submissions are typically not considered, no matter how competitive your pricing is.
Follow-Up After Bidding
Once your bid is submitted, don’t just sit and wait. Reach out to the GC with a polite follow-up email or call to confirm receipt and ask if they need any clarifications. If you don’t win the bid, seek feedback to learn where you can improve. Staying on their radar ensures you’re considered for future projects.

Mistakes to Avoid While Bidding
Avoid bidding on projects without fully understanding the scope. This often leads to disputes and lost money.
Don’t ignore change orders; make sure you have a plan for handling modifications during construction.
Also, remember to account for inflation or price fluctuations, especially on long-term jobs.
Legal and Contractual Considerations
Always review your contract before signing. Understand the terms, payment schedule, penalties, and liability clauses. Know what insurance and bonding requirements apply to the project. Being legally prepared protects your business and avoids disputes later.
Conclusion
Bidding as a subcontractor isn’t about luck—it’s about strategy, preparation, and professionalism. When you understand the process, accurately estimate costs, and submit polished, well-thought-out bids, you position yourself for consistent success. Keep refining your process, invest in the right tools, and focus on delivering real value. That’s how you win more jobs and grow your subcontracting business.
