Hiring A Commercial Contractor

Most business owners start the contractor search backwards. They collect a few names, send out bid invitations, get some numbers back, and pick the lowest one. Then they wonder why the project ran over budget and behind schedule. The problem is not the contractor market. The process is the problem.

At Ascension Construction, an Indianapolis-based commercial general contractor, we have seen both sides of this more times than we can count. The owners who get good outcomes are not lucky. They are methodical. They do the work before a single contractor shows up at the table, and that preparation changes everything about how the project goes.

This checklist covers 10 specific steps to help you hire a commercial construction contractor with confidence, from initial scoping through contract review. It covers licensing, insurance, references, bid comparison, and contract terms. Follow it in order, and you will not get caught off guard.

1. Get clear on your project before you start searching

The most common reason a hire goes wrong is that the owner was not clear on what they needed before talking to anyone. Before you contact a single contractor, define the project on paper. Scope, budget, and timeline all need to be established before you open the door to bids.

Know whether you need a general contractor or a specialty contractor

A commercial general contractor manages the full scope: planning, permits, subcontractor coordination, inspections, and delivery. A specialty contractor handles one trade. If your project involves multiple trades, a full space buildout, or a renovation that touches multiple systems, you need a GC, not a collection of individual vendors. Hiring specialty trades separately without a GC coordinating the work is one of the most reliable ways to create scheduling chaos and accountability gaps.

Set a realistic budget range before collecting bids

Without a budget range, you cannot evaluate whether a bid is reasonable or a red flag. Talk to a few local GCs informally, review published cost-per-square-foot ranges for your project type, and establish a working number before formal bidding begins. Most experienced contractors can sense when an owner has no budget anchor, and that uncertainty tends to produce padded bids, misaligned proposals, and more friction during negotiation. Everyone ends up in a worse position.

Define the timeline and how it affects contractor availability

A contractor fully booked for the next four months is not the right hire, even if their work is excellent. Know your required start date and completion deadline before you shortlist anyone. Schedule fit is just as important as skill fit. Overlooking this step is a common source of mid-project crew pullouts and costly delays that no contract clause can fully fix after the fact.

2. Verify Credentials Before Hiring a Commercial Construction Contractor

This step gets skipped more than any other, and it is also the most consequential. Credentials are not a formality, they are the baseline for whether a contractor can legally and safely operate on your project.

How to check a contractor's license and bond status

In Indiana, commercial general contracting is licensed at the local city or county level rather than through a single statewide license. Requirements vary by jurisdiction, so check what your municipality requires. Specialty trades are a different matter: electrical, plumbing, and HVAC each require separate state-regulated licenses. Confirm that any GC you are considering ensures their specialty subcontractors carry the appropriate trade licenses before bringing them on your project.

What insurance coverage to require and how to verify it

At minimum, require a certificate of insurance showing general liability and workers' compensation. For most mid-size commercial projects, the standard general liability requirement is $1 million per occurrence and $2 million aggregate, thresholds consistent with industry norms, though your specific project scope and risk profile may warrant higher limits. Do not accept a verbal confirmation. Ask for the actual certificate listing your business as an additional insured, and verify coverage amounts are appropriate for your project scope before moving forward. Because coverage implications and endorsement forms vary by jurisdiction, confirm the exact wording with your insurance counsel.

Why workers' compensation matters even for subcontractors

If a subcontractor is injured on your site and their employer carries no workers' compensation, your business may be exposed to liability. Confirm that your GC requires coverage from every subcontractor they bring on your project. A reputable GC will have a process for collecting and verifying subcontractor certificates before work begins. If they do not, that tells you something important about how they manage risk generally.

3. Evaluate their track record with real questions, not just portfolios

A polished portfolio on a contractor's website is marketing. What you need is evidence of how they actually perform under pressure on projects similar to yours. That evidence lives with past clients and project teams, not in photos.

How to review project history for relevant experience

Ask specifically for completed projects that match your project type, size, and delivery timeline. A contractor with strong retail buildout experience is not automatically a good fit for a healthcare renovation. Relevant experience reduces execution risk in ways that raw years in business simply do not. The more similar the prior work, the more predictive their track record becomes.

The reference check questions that reveal real performance

Contact past clients directly. Ask whether the project finished on time and on budget. Ask what went wrong and how the contractor handled it. Ask whether they would hire that contractor again without hesitation. Vague or reluctant answers are as informative as direct ones. A reference who pauses before saying yes is a reference worth following up on.

Interview questions that predict on-site execution

Ask who will actually manage your project day to day, not just who is presenting in the meeting. Ask about their current workload and how many projects the same team is running simultaneously. Ask how they communicate progress, delays, and decisions. Get specifics on tools and meeting cadence. General promises about responsiveness mean nothing without a concrete process behind them.

4. Compare Bids Carefully When Hiring a Commercial Construction Contractor

Most owners look at the final number on a bid and start comparing from there. That approach consistently leads to the wrong decision, and the cost of that mistake shows up weeks into construction when it is too late to change course.

Why the lowest bid is often the riskiest

A low bid often reflects missing scope, understated allowances, or a contractor cutting corners on supervision and coordination costs. Once work starts and scope gaps emerge, change orders bring the final cost well above what a more complete bid would have delivered. The lowest number on day one rarely ends up being the lowest number at completion.

How to read general conditions, markups, and allowances

General conditions cover project-level costs: supervision, temporary utilities, permits, scheduling, cleanup, and site management. On commercial projects, general conditions typically represent 8 to 12 percent of total project cost, though ranges can vary by project type and complexity. When comparing bids, request an itemized general conditions breakdown from each contractor, do not rely on a single lump sum. Allowances are placeholder amounts for items not yet selected, like flooring or fixtures. Two bids can show the same bottom line while carrying very different general conditions and allowance levels. Compare these line by line, not in total, before drawing any conclusions.

What to ask when bids come in significantly different from each other

A gap of more than 15 to 20 percent between bids often points to a scope difference, not a pricing difference. Ask each contractor to walk through what their bid does and does not include. Exclusions, allowance amounts, and what is covered under general conditions are where the real differences live. Normalize the scope first, then compare the numbers.

5. Review the contract before you sign, and know what to walk away from

A solid contract protects both parties. It also tells you a great deal about how a contractor operates before any work begins. If they push back on including standard provisions, that is useful information.

The contract clauses every commercial project owner must insist on

At minimum, the agreement should include a clear scope of work, a defined payment schedule tied to milestones or draw dates, a written change order process with approval requirements, a warranty provision specifying coverage period and correction obligations, and liquidated damages language if schedule performance is critical. These are not extras. They are the foundation of a professional commercial contract.

Warning signs to walk away from before you sign

Contractors who pressure you to sign fast, refuse to pull permits, ask for large upfront payments, or provide vague scope language are showing you exactly how they will operate during construction. Unlicensed specialty work, missing insurance certificates, and no physical business address are immediate disqualifiers. These are not negotiation points. They are exit signals.

Payment schedule structure that protects both sides

A reasonable commercial contract structures payments as milestone-based draws or monthly progress billings with retainage held until substantial completion. Avoid contracts that front-load payments heavily before work begins. Retainage, typically five to ten percent on projects under two million dollars, consistent with common industry practice, gives you leverage to ensure the project is properly closed out. Note that public projects may be subject to statutory retainage caps that differ by state. Retainage protects you without being punitive to a contractor who performs well.

The right process changes everything when you hire a commercial construction contractor

Selecting a commercial construction contractor does not have to be a gamble. The owners who get it right are not lucky. They define the project before they shop, verify credentials before they meet, and ask hard questions of references. They interview the actual team that will run the job, read bid line items instead of just totals, and review the contract before they ever hand over a dollar.

That process filters out most of the risk before a single nail is driven. It also signals to the contractors you are considering that you are an owner worth working for, which tends to attract better performance from the start.
