10 Tips for Subcontractors Bidding CMAR or CMGC Projects
Bidding on a major infrastructure project with a Construction Manager at Risk (CMAR) or Construction Manager/General Contractor (CM/GC) is a strategic opportunity for subcontractors. These projects are complex, highly structured, and require subcontractors to submit complete, competitive, and well-documented proposals to secure work successfully. To stand out, small businesses must demonstrate capability, compliance, and clarity in their bids.
The terms CMAR (Construction Manager at Risk) and CM/GC (Construction Manager/General Contractor) are often used interchangeably because they represent the same project delivery method. In this model, the construction manager also acts as the general contractor, providing preconstruction services, construction management, and assuming financial risk for the project. Projects procured using this method protect the owner from cost overruns while allowing flexibility in scope and pricing.
How are CMAR or CM/GC projects different from low-bid projects? Low Bid (or Hard Bid) contracts are awarded to the lowest priced qualified contractor. Contractors bid based on fully completed design documents, and there is no pre-bid collaboration between the owner, construction manager, and subcontractors.
At Kuniklo Corporation , we have facilitated connections between estimators and subcontractors, trained subcontractors on the CMAR bidding process, and provided technical assistance to small subcontractors approaching large-scale projects. With over twenty years of experience, we have helped businesses navigate the bidding process with confidence and ensure they are well-prepared when engaging with CMs and GCs. We have helped CM/GCs by strengthening the pool of qualified subcontractors, improving bid accuracy, and reducing scope gaps that can lead to project delays. From lessons learned, here are ten tips to help subcontractors successfully bid on these projects.
10 Tips for Subcontractors Pursuing CMAR or CMGC Projects
1️⃣ Ensure Complete and Accurate Company Information Make sure your business name, address, phone number, email, and contractor’s license number are up to date and match official records. This confirms your legitimacy and makes it easy for the CM/GC to verify your eligibility and contact you with questions or clarifications.
2️⃣ Identify the General Contractor and Project Details Your bid should clearly state the General Contractor or CM, project name, and bid package reference number. Always confirm the bid due date and submission format to ensure compliance and avoid disqualification.
3️⃣ Define a Clear Scope of Work A successful bid outlines exactly what work your company will perform based on the bid package requirements. Clearly define labor, materials, and specific tasks involved to reduce the risk of scope gaps that could lead to change orders later. Subcontractors should also be prepared for scope refinement during preconstruction discussions, a key element of CMAR projects.
4️⃣ Provide a Detailed Pricing Breakdown A well-structured bid includes base bid amounts, alternate pricing (if applicable), and a breakdown of labor, materials, equipment, overhead, and profit. Include the quantities used to reach your price. Be sure to account for potential material price increases and escalation costs for long-term projects. Since CMAR projects often refine costs before finalizing the GMP, subcontractors should expect collaborative pricing discussions.
5️⃣ Clearly List Inclusions and Exclusions Clearly state what is included in your bid, such as materials, mobilization, and site cleanup. Equally important is listing exclusions—define what you are not responsible for to prevent disputes later. CMAR projects require precise scope definition to ensure alignment with project goals.
6️⃣ Include a Realistic Project Schedule Provide a realistic start and completion date, considering manpower availability, material procurement lead times, and possible delays. Ensure your schedule aligns with the project’s overall timeline. A preliminary project schedule is generally provided in the bid documents. CMAR projects rely on subcontractors who can coordinate effectively within an evolving project schedule.
7️⃣ Understand Key Terms and Conditions Your bid should include key contract terms such as bid validity (30-60 days), payment terms (progress payments, retainage, and final payment schedules), and how change orders will be handled. CMAR projects require a higher level of collaboration, so subcontractors must be flexible while aligning with the project’s Guaranteed Maximum Price (GMP or GMAX) structure.
8️⃣ Demonstrate Compliance and Certification Requirements Many large infrastructure projects have prevailing wage rules, DBE/SBE participation goals, and safety regulations. Include proof of relevant certifications, compliance with Davis-Bacon wages (if required), bonding capacity, and insurance certificates to demonstrate your company’s qualifications. CMAR projects often have specific diversity and inclusion goals, making compliance readiness a competitive advantage.
9️⃣ Ensure Proper Bid Formatting and Authorization A bid may be rejected if it lacks a proper signature from an authorized representative or if it is not formatted according to the CM/GC’s requirements. Double-check the required submission format—electronic, printed, or portal upload—and confirm receipt with the CM/GC when possible.
🔟 Include Supporting Attachments Enhance your bid by attaching a material list, proof of insurance, relevant project references, and any additional requested documents such as subcontractor prequalification forms or safety records. Strong supporting documentation reinforces your company’s credibility and experience.
Final Takeaway
Winning work with a Construction Manager under a CMAR or CMGC contract requires more than just submitting a low price—it demands a well-structured, complete, and professional proposal that aligns with the project's collaborative nature and pricing model. CM/GCs value subcontractors who understand how to work within this structure, ensuring smoother preconstruction coordination and stronger project execution. By ensuring these ten key items are included in every bid, subcontractors can improve their chances of selection and build strong working relationships with CMs and GCs for future opportunities.
