SPECIALTY CIVIL CONSTRUCTION

With a substantial history of large scale excavation and earthwork, Great Lakes E&I has developed specialty civil construction capabilities to provide innovative solutions for our clients’ clean construction challenges. We selectively pursue specialty civil and geotechnical construction projects that are ideally suited to our in-house resources and expertise. We seek opportunities that competitively add value, using our own experienced staff and fleet of equipment. Typically, this includes large scale excavation, shoring, grading and/or trenching, or projects with an environmentally sensitive component.

PROJECT HIGHLIGHT

EASTMAN LAKE LANDSLIDE & PAVING
EASTMAN LAKE, CA

  • Installation of approximately 800 20 ft and 24 ft long post-tensioned SuperRockBolts™
  • Road protection with trench plates and k-rail

PROJECT HIGHLIGHT

SFWMD RS-G341 CONVEYANCE IMPROVEMENTS
SEGMENTS 1&2
BELLE GLADE, FL

  • Dewatering of canal and farm ditches to elevation 0.0 using 24 in hydraulic pumps
  • Blasting of 12,700 lf of 40 ft wide canal 
  • Excavation of 12,700 lf of canal to elevation -2.0
  • Placement of muck on rock core spoil pile embankment to minimum elevation of 15.5
  • Installation of drainage culverts

Great Lakes Environmental & Infrastructure (Great Lakes E&I) was contracted to provide services for the RS-G341 Conveyance Improvements project for the South Florida Water Management District (SFWMD) in Belle Glade, Florida. Dewatering of the project area was completed after the installation of cofferdams to block off water from the existing Bolles Canal to the east and west of the project. Four cofferdams were constructed and dewatering was completed in three sections using 12 to 24 in diameter hydraulic pumps. Following dewatering of each section, muck within the proposed excavation and spoil pile embankment footprint was removed and stockpiled outside the proposed embankment footprint. Muck was removed to expose a limestone rock layer beneath the muck. Once muck was removed, the proposed canal excavation cross section was drilled and blasted to break up the limestone rock layer within the proposed footprint of the new canal.
