Water Lines

New Phase I – Double Eagle Waterline

Owner: City of Carlsbad
Engineer: Molzen-Corbin & Associates
Location of Project: Maljamar, NM
Final Contract Amount: $9,351,098
Completion Date: June 2015

Award Received:
2015 Associated General Contractors-New Mexico Building Branch (AGC-NM) Best Buildings Award–Municipal and Utilities

Project Description:
The New Phase I – Double Eagle Waterline Project presented many unique challenges, so the Owner chose to use a qualifications-based selection process to select AUI as the Contractor. The project scope included:

  • Over 3.5 miles of 24” water transmission line
  • Over 11 miles of 16” water transmission line
  • Four jack and bore crossings under state and county roads and 59 jack and bore crossings under other utilities
  • Four pressure reducing/pressure sustaining stations in pre-cast concrete structures
  • Associated shutoff valves, air release/vacuum valve stations, and appurtenances

Located between Carlsbad and Hobbs, the Project spanned a remote area of about 20 miles. The numerous hills and soft, sandy soil required 4-wheel drive trucks to traverse and limited the ability to get equipment in and out.

The Project area contained dozens of gas and oil lines, from 2” to 16”, running both above and underground. More than one excavation site had in excess of 30 existing utility lines that had to be protected while carefully trenching in the area. Many of the underground lines had to be crossed by the new waterline. All major underground crossings required jacking and boring, and lines were buried up to 13-feet deep, requiring bore pits of 16- to 17-feet. To further complicate the situation, the oil and gas lines running through the Project area had more than 30 different owners.

Approximately two-thirds of the Project area was designated as an “Environmental Area.” This area is habitat for the potentially endangered Sand Dune Lizard and Lesser Prairie Chicken. In addition to providing special precautions to protect these species, any wildlife discovered in the active Project area had to be relocated by the New Mexico Environmental Department (NMED) monitor prior to work continuing. Even rattlesnakes were protected in this area, and some were encountered during the Project. This area was also restricted to having no more than 400 feet of trench open at any one time. Even though the total contract time allowed for the Project was one year, all of the work in the Environmental Area (2/3 of the job) had to be constructed between August 1st and November 30th to avoid disrupting the nesting season of the Sand Dune Lizard. This seemingly insurmountable schedule milestone was met by overlapping crews working 16-hour days, seven days a week, including staggering lunches for crews so that equipment never stopped working.

Because the locations for water were so far apart (only four locations over the 20-mile Project area), and the terrain was not suitable for water trucks, we had to find another way to get water for dust control and backfill to the needed locations. The Project superintendent had our crews weld taps into the existing steel waterline every 5,000 feet. He then used 2,500-foot sections of 2-inch poly hose with a tee installed every 500 feet to have water available anywhere it was needed.

These are just a few of the many unique challenges that had to be overcome to successfully complete the Project. By responding to the challenges with innovative solutions, AUI completed the Project on time and on budget with a high level of quality.

 

 

Special Assessment District #228

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.

Effluent Reuse Pipeline Improvements Contract 2

Owner: Albuquerque Bernalillo County Water Utility Authority
Engineer: Wilson & Company
Project Location: Albuquerque, NM
Contract Amount: $7,029,510.19

The Effluent Reuse Pipeline Improvements project included the installation of 27,500 LF of large (30” to 16”) and 28,200 LF of small (12” to 4”) diameter pipeline with appurtenances in southeast Albuquerque from University Boulevard by the Albuquerque Sunport Aviation Facility north towards the University of New Mexico sports facilities on University Boulevard and also east up to Louisiana Boulevard.  The pipeline threaded its way through arterial and residential roadways towards public parks, golf courses and other sports facilities to provide stub outs which will eventually be connected to the existing irrigation systems in order to replace the potable water supply currently being utilized.  Roadway surfaces and structures were removed and replaced in-kind.

Working through the middle of congested arterial corridors and established residential neighborhoods, AUI was met with a complicated maze of underground public utility lines.  Exhaustive efforts were made to pre-locate and expose the numerous gas lines, sanitary sewer and storm drain lines, water mains and services, communication lines, street lighting and traffic signal lines the length of the project.  AUI’s vacuum excavators were used to pothole and explore without damaging the facility.

In an effort to minimize the duration of disturbance through residential areas, AUI worked extended hours, seven days a week.  Extensive planning and coordination was required to keep the fast paced project moving smoothly without obstructing or restricting access of the public.

UNM Domestic Water Phase 5

Owner: The University of New Mexico
Engineer: WHPacific, Inc.
Location of Project: Albuquerque, NM
Final Contract Amount: $1,162,520.55

The scope of work for this project included installation of 3,370 LF of 10” water line through the most central and heavily utilized sections of the University of New Mexico (UNM) main campus. The path of the water line crossed existing pedestrian walkways, mature landscaping and existing irrigation lines. This project was scheduled for construction during the summer break months to allow enough time for completion of the project while the student and faculty population would be at a minimum. Offering a large selection of classes during the summer break and many students take advantage of the fast-track summer semester classes to gain additional credit hours; presented some challenges during the construction of this project.

This project also included a portion of the water line installed within the utility tunnel. Installation within the tunnel required AUI crews to work in severely constricted space, with limited access, and in close proximity to live utility lines within the tunnel. AUI crews completed this portion of the project successfully.

This project serves as a clear demonstration of AUI’s ability to remove and replace waterline on a University campus setting, within constricted spaces, to manage utility replacements and new installations within complex existing utility systems, and to care for existing utilities during all phases of construction. AUI completed this project well within the contract amount and calendar days allotted by the Owner.
