Removing boulders to allow trenching for utilities

Removing boulders to allow trenching for utilities

Owner: City of Albuquerque
Engineer: Wilson & Company
Location of Project: Albuquerque, NM
Contract Amount: $26,750,711
Completion Date: June 2014

AUI’s largest site development project to date, Special Assessment District (SAD) #228 consisted of 72-acres of site work including:

  • Over 65,000 CY of rock excavation requiring extensive blasting and rock trenching
  • Over 200,000 CY of import fill material
  • Over 50,000 TN of base course material
  • Over 200,000 SY of superpave asphalt concrete
  • Over 90,000 LF of concrete work that included curb and gutter, sidewalks, ADA ramps, and driveways
  • Over 12,000 LF of reinforced concrete pipe in various diameters from 18-in to 96-in
  • Approximately 38,000 LF of 8-in to 18-in diameter PVC sanitary sewer pipe installation, 2,000 LF of 6-in ductile iron forcemain, and 1,500 LF of 2-in PVC forcemain, plus a lift station
  • Over 200 manholes ranging in diameter from 4-ft to 10-ft
  • Approximately 42,000 LF of 4-in to 12-in diameter PVC waterline requiring over 30,000 lbs of ductile iron fittings
  • Water and sanitary services to approximately 430 individually owned properties
  • Over 66,000 LF of dry utility installation to include electrical, communication, and natural gas infrastructure
  • Signalization and lighting
  • Signage and striping
  • Garden walls and landscaping
  • Bike trail

The extensive rock removal on the project had numerous challenges. Basalt formations were very diverse and unpredictable; a single formation could contain voids, veins, and cracks which made blasting difficult due to the unpredictable release of pressure. Blasting was required directly above existing residences and both above and adjacent to active arterial roadways. The entire site was adjacent the Petroglyph National Monument, containing federally protected artifacts. We mitigated these challenges by using vibration and air blast monitoring for all rock blasts, utilizing both permanent and roving monitoring stations.

The fixed Owner’s budget with minimal contingency required careful budget management, especially since the entire design was preliminary and had to be constantly modified to meet the intent. We were also required to provide access to over 300 private land owners throughout the project.

Combat Aviation Brigade (CAB) Water and Sewer Infrastructure Phases III & IV

Owner: Army Corps of Engineers
Engineer: Brown & Caldwell
Location of Project: Fort Bliss, Texas
Contract Amount: $7,171,179

AUI was asked to perform this scope of work under an accelerated schedule which was accomplished utilizing a 7 day work week with a consistently scheduled transition of crews and equipment. This allowed for maintaining effective daily production and adherence to the schedule despite unforeseen changes in conditions. AUI’s contracted scope of work included the installation of approximately 17,940LF of C-900 PVC water line of various sizes ranging from 4” to 24”, including meters and valve vaults. Also involved in this project was the installation of approximately 9,225LF of SDR-35 PVC sanitary sewer pipe of various sizes ranging from 6″ to 12” and installation of approximately twenty-nine 48″ precast manholes including all necessary appurtenances and coatings. Additional work included removal and disposal of approximately 5,400LF of asbestos contaminated pipe ranging from 4“ to 12”. AUI was also involved in the demolition, removal and replacement of the existing ground and elevated water storage tanks. This work included, but was not limited to SCADA, yard piping, special coatings and cathodic protection.

AUI’s on-going presence at Fort Bliss has enabled us to become familiar with the base required processes and procedures for participation in construction activities on a military installation from safety regulations, permits and badging, to protocols that are to be followed with the Director of Information Managements (DUIM) and other base entities possibly affected by our scope of work.

Combat Aviation Brigade (CAB) Water and Sewer Infrastructure Phases I & II

Owner: Army Corps of Engineers
Engineer: Brown & Caldwell
Location of Project: Fort Bliss, Texas
Contract Amount: $8,511,910

AUI built and maintained a solid relationship with Brown and Caldwell, Fort Bliss Water Services, Co. and the Army Corps. of Engineers throughout the CAB Phase I and II Project which in turn lead to the completion of Phase I ahead of schedule and the start of Phase II earlier than anticipated. AUI was contracted for the demolition and replacement of existing water and sanitary sewer. This water and sewer infrastructure project included construction of approximately 23,887LF of 8”, 12” and 15” respectively of SDR-35 PVC sanitary sewer  pipe in addition to 33,903 LF of C-900 PVC pipe waterline varying in sizes from 6” to 12”, which included all necessary fittings, valves, and appurtenances. Contracted work also involved the installation of approximately eighty-five 48” precast manholes with required appurtenances and coatings, and twenty-eight fire hydrants. During the installation and tie-ins of new services, AUI installed temporary connections as necessary to maintain services, ensuring limited interruptions for the Fort Bliss area.

AUI was presented with a safety award from the Corps of Engineers while working this project, exemplifying our dedication to the safety of our employees.
