Capability
Five service lines. One contract, one accountable party.
You can hire us as the general contractor who holds everything, or as the specialist who does one hard thing better than anyone else on the shortlist. Both are legitimate. We will tell you which one you actually need.
Choosing a delivery route
The question is not which method is best. It is which risk you want to hold.
Progressive design-build transfers the most risk to the contractor and is usually the fastest route on complex, poorly defined scopes, which is why we use it on roadway and industrial work where the existing conditions are genuinely unknown. CM/GC gives the owner a seat at every table but requires the owner to make decisions on schedule. Low-bid transfers risk to everyone and satisfies nobody, and we will say so in the interview.
Our honest advice: if your scope is well defined and the site is clean, do not pay a premium for design-build. If it is neither, do not try to low-bid it.

Working with us
What you can expect, and when.
Nothing below is unusual in this industry. It is simply what we commit to in writing, and what you can hold us to.
| Stage | What happens | Committed turnaround |
|---|---|---|
| First contact | Call the switchboard any hour. The automated receptionist records your project type, location, scope and budget, and schedules a call-back with the right estimator. | Same business day |
| Go / no-go | A named preconstruction lead reviews the opportunity against our capacity and licence coverage, then tells you honestly whether we are pursuing it. | 2 business days |
| Estimate | Constructability review, site walk where access allows, and a written basis of estimate with quantities and assumptions exposed. | 10–15 business days |
| Interview | Named superintendent, project manager and safety lead attend in person, with a project-specific hazard analysis. | As scheduled |
| Mobilisation | Buyout complete, submittal register issued, utility locate and risk register closed out before the first crew arrives. | 30 days from NTP |
| Reporting | Cost-loaded schedule, earned value, safety metrics and change log published to the owner weekly. | Weekly |
| Turnover | As-built drawings, O&M manuals, training, warranty register and digital twin handed over before final acceptance, not after. | At substantial completion |
Urgent field or emergency matters should be directed to (303) 555-0199, staffed 24 hours a day, 365 days a year.
Questions
Service questions we hear most.
Email bids@ironwoodgroups.com with your company profile, trade classification, bonding capacity and three references. Our preconstruction team reviews new subcontractor and supplier applications monthly and will confirm your classification in writing.
Bidding & Suppliers
Yes. We self-perform earthwork, structural concrete, structural steel, deep foundations, mechanical and piping, and electrical and instrumentation work as a subcontractor to other primes, particularly on projects outside our four core markets.
Bidding & Suppliers
Our surety programme supports $750M single-project and $1.5B aggregate bonding capacity through an A+ XV rated, Treasury-listed surety. We can provide letters of bonding capacity on request within one business day.
Bidding & Suppliers
Every brownfield project begins with a joint risk assessment alongside the facility operator, producing a project-specific safety plan and permit-to-work matrix before mobilisation. We staff a dedicated Site Safety and Health Officer on any project over 200,000 hours, and we work to the operator's permit system, not ours.
Safety & Quality
The Experience Modification Rate is an insurance industry measure comparing a contractor's injury record to its peers; 1.00 is average, and lower is better. Our three-year rolling EMR is 0.61, which lowers our workers' compensation cost and, more importantly, is the clearest evidence we can offer that our safety programme is real rather than a document.
Safety & Quality
Yes. All work carries a standard one-year warranty in addition to any longer manufacturer or specified warranty, and we administer warranty claims directly rather than routing them through a subcontractor. Structural and waterproofing warranties extend to the period specified in the contract documents.
Safety & Quality
Yes. Since 2014 the majority of the company has been held by an Employee Stock Ownership Plan, which means every eligible employee is a shareholder at no cost to them. It is the single largest reason our field leadership tenure averages eleven years.
Company
Ironwood was founded in Denver in 2001 and has operated continuously since. We have worked in 34 states, four Canadian provinces and four countries.
Company
Our emergency line at (303) 555-0199 is answered 24 hours a day, every day of the year. Calls to the main switchboard after hours are answered by our automated receptionist, which will take your details and page the on-call duty manager immediately.
Company
Yes, and we prefer to. Our registered apprenticeship programmes in operating engineering, ironwork, carpentry and electrical take candidates with no prior trade experience, pay a wage from day one and provide paid classroom instruction. Applications open each February for a summer intake.
Careers
For field leadership, engineering and professional roles, yes, typically a lump sum or a managed relocation package. Many of our projects also carry per diem and rotational schedules for candidates who prefer to travel rather than relocate.
Careers
We actively recruit transitioning service members and veterans, particularly for field supervision and safety roles. Our Federal Programs group is led by a retired U.S. Army Corps of Engineers officer, and we participate in SkillBridge and Hiring Our Heroes.
