VILLAGE CENTER STATION

Diamond Excavating is the excavation and utility infrastructure contractor for new Village Center Station in Greenwood Village, Colorado, including the office towers, plaza and parking structure.

MORNINGSTAR BOULDERS

200 tons of "hand picked" boulders were precisely placed, then specially grouted-in to create a natural flow for water and erosion management along Windmill Creek at MorningStar Assisted Living and Memory Care.

ANTHEM MEMORY CARE

More than 15 thousand cubic yards of earth were moved. Excavated for large multi-level retaining walls. Wet utilities included a water line loop with fire hydrants and building services, sanitary, storm water management.

The 90,000-square-foot school Park Street Elementary School demonstrated the complexities of pipeline installations handled by Diamond Excavating. A reinforced concrete pipe with sewer line and grease interceptor crosses over storm lines.

High-End Custom Homes

Multi-level excavation, specialized foundation and footer support excavation, as well as underground utilities and demolition of pre-built site locations with site preservation a priority.

Marquez Hall - School of Mines

A 23-foot overexcavation and a complex tie-in for a new tunnel. Diamond offered a professional level of value engineering for the tunnel excavations and tie-ins.

POUDRE VALLEY HEALTH SYSTEM

The Cancer Center addition to the existing hospital required significant structural fill import, placement and foundation backfill, along with tie in to existing wet utilties.

RTD JEFFCO PARKING

MAIN LINE TIE-IN

Diamond is experienced in cut-in and wet-tap tie-ins to main line infrastructure. These projects typically require roadway traffic control, crossing of existing utility system lines, and carefully managed excavation.

COBANK BUILDING
