Steel and concrete bridges, box culverts, cast-in-place and precast concrete, riprap, retaining walls, and rock sourced direct from quarries. Site work and installation by Coal Creek Excavation.
We are an excavation contractor, so the dirt and concrete side of a job is our everyday work. We also build the heavy civil pieces that go with it: bridges, culverts, channel and slope armoring, and retaining walls.
From our office in Erie we work across Boulder County, Larimer County and the Front Range, and we take this work in Pagosa Springs and Archuleta County.
Tell us what you need and we will tell you whether it fits. These are the heavy civil services we take on.
Bolt-together galvanized steel girder bridges for driveways, ranches and access roads over creeks and ditches, in spans from about 12 to 60 feet. We build the abutments and install the bridge.
Concrete bridge superstructures, built as cast-in-place or precast, for crossings that need a concrete span. We handle the site work, abutments and installation. The design is engineered to your site by a licensed PE.
Precast and cast-in-place box culverts for creek crossings, drainage, and replacements of undersized or failing culverts.
Cast-in-place concrete for bridges, culverts, headwalls, abutments and other heavy civil structures. We pour our own concrete.
Precast concrete for bridges, culverts and headwalls, set and tied into the site work we build around them.
Riprap for channel and slope armoring, to protect banks, crossings and slopes. Rock is sourced direct from quarries.
Retaining walls and hardscapes that hold up to Colorado weather, including walls that are part of a crossing, a slope or a site-development job.
Riprap, rock and aggregate sourced direct from quarries for the work above, and for site work that needs it.
