Denver has been building for years — towers along the Platte, infill projects across RiNo and the central neighborhoods, warehouses out toward the airport, and endless roadwork on I-25 and I-70. Every one of those sites depends on workers doing genuinely dangerous jobs at height, around heavy equipment, in trenches, and near live traffic. When something goes wrong, the injuries are rarely minor: falls, crush injuries, electrocutions, struck-by incidents involving equipment or vehicles.
Most injured construction workers are told the same thing within days: 'You're covered by workers' comp.' That's true as far as it goes — and it doesn't go far. Workers' compensation covers medical care and a portion of wages, but nothing for pain, nothing for the full scope of lost earning capacity, nothing for what your spouse and kids lose. What that early conversation conveniently omits is the third-party claim: the separate lawsuit you may have against someone other than your employer who helped cause the injury.
Whiteford Mountain West investigates Denver construction accidents from our office in the Highland neighborhood, backed by Whiteford's national trial platform. This page explains how third-party claims work, who the defendants usually are, and why the difference between 'a comp claim' and 'a comp claim plus a third-party case' can define your family's recovery.
Third-party claims: the case beyond workers' comp
Workers' compensation is a trade: you get benefits without proving fault, and in exchange you generally can't sue your own employer. But that bargain only binds you and your employer. Modern Denver job sites are crowded with other companies — general contractors, other trades' subcontractors, equipment lessors, delivery drivers, property owners, engineers — and none of them are shielded by your employer's comp coverage. If their negligence contributed to your injury, you can pursue them in a full civil claim for everything comp doesn't pay.
These cases turn on untangling who controlled what. Site-safety responsibility on a multi-employer project is defined by contracts, safety plans, and day-to-day practice — who ran the safety meetings, who had authority to stop work, whose crew created the hazard. That paper trail, plus OSHA findings and witness accounts, is where third-party liability gets proven, and it's why early investigation matters so much.
- General contractors who controlled site safety but let hazards persist
- Subcontractors from other trades whose work created the danger
- Equipment manufacturers and rental companies, when machinery or scaffolding fails
- Drivers who strike workers in roadway work zones
- Property owners and developers, in some circumstances, under Colorado premises law
Common Denver construction injuries — and why the evidence disappears fast
Falls from height remain the most consistent source of serious construction injuries — from scaffolds, ladders, roofs, and unguarded edges — followed by struck-by incidents, trench collapses, electrocutions, and crush injuries around cranes and heavy equipment. In roadway work zones along I-25, I-70, and metro arterials, workers face the added danger of passing drivers, which often makes the third-party defendant obvious.
Construction sites change daily by design. The scaffold gets rebuilt, the trench gets filled, the site gets cleaned up — often within days of an incident, and sometimes faster when liability is in the air. Photographs, witness names, equipment maintenance records, and safety-plan documents need to be preserved almost immediately. An injured worker recovering in a hospital can't do that, which is exactly why early legal help changes outcomes in these cases.
How we handle Denver construction cases
We investigate the site while it still tells the truth: preservation letters, site photographs, witness interviews, equipment records, and the contract documents that reveal who actually controlled safety. We coordinate carefully with your workers' comp claim, because the two cases interact — comp carriers typically assert repayment rights against third-party recoveries, and managing that interaction well protects what actually reaches your family.
It starts with a free consultation, and an honest answer: if there's no viable third-party claim, we'll tell you that plainly rather than sell you false hope. If you want a first read before talking to anyone, our free case estimator is an educational place to start. Call (720) 821-3784 — the sooner the site is documented, the stronger your position.
