Storm Drain

13th Street Reconstruction – Phase I

Installing the triple 60-inch storm drain

Owner: City of Artesia
Engineer: Smith Engineering Company

Location of Project: Artesia, NM
Contract Amount: $8,524,429
Completion Date: July 2015

This project was a full-width street reconstruction including over 10,000 LF of 60-in storm drain plus water lines, valves, fire hydrants, sanitary sewer line, manholes, sub-grade prep, base course, hot mix asphalt paving, concrete paving, concrete curb and cutter, sidewalks/fillets, and signalized intersections.  AUI completed the project within budget and over two months ahead of schedule.

The project site was constrained by the 32-ft street width. The triple 60-in storm drain installation required complete excavation and a trench width of 25-ft, plus access for material removal. Careful planning and execution was necessary to avoid damaging nearby facilities. The existing infrastructure was quite old, leading to numerous unknown utilities. We avoided damage by potholing each area prior to beginning excavation.

“It has been one of the most efficiently managed projects I have ever been associated with.”

The project area included a school, a hospital, parks, businesses, and residences. Extra care was required to maintain both vehicle and pedestrian safety. In addition to cordoning off work areas, AUI held a “Safety Day” at the elementary school. We placed a piece of the storm drain pipe in the school parking lot and let the children walk through it to understand how large it was. We also brought in and demonstrated a trackhoe. We talked about what the heavy equipment does and how much it weighs, as well as explaining the reasons for the construction fences.

Because maintenance of access was required for all constituents throughout the project, we completed the project in four phases to limit the number of alternative entrances required at any one time. Utility services also had to be maintained during construction so bypass pumping was used to maintain sewer service during construction.

Special Assessment District #228

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.

Lead and Coal Avenues serve as main arterials connecting downtown Albuquerque to its east side. The project involved over five and a half miles of construction through the heavily traveled residential area. In addition to resident and business access, mail, bus service, garbage pick-up and other services had to be maintained throughout the project, and heavy pedestrian traffic was a concern with the project’s proximity to CNM and UNM.

The existing three-lane streets that encouraged speeding and weaving were replaced with two-lane streets that included traffic-calming features and encouraged multi-modal transportation. The project made the entire corridor ADA accessible with the installation of over 500 wheelchair ramps. In addition, designated transit stops with shaded structures were installed, bike lanes were added throughout the length of the project, and the existing 3’ sidewalks were widened to a minimum of 6’ wide. Over 18,000 cubic yards of concrete were placed within the project.

The inadequate storm drain system and aging infrastructure were updated, including installation of up to 66” diameter storm drain that had to be placed up to 20’ deep in some sections. The project also included signalization and roadway lighting; fiber optic cable, splicing and terminating; CCTV installation; traffic count station installation; signing and striping; garden walls, retaining walls and landscaping. The 18-month project was completed on time and under the City’s budget.


Paseo Del Volcan (Northern Section) Stage II, IRIS to US 550

City of Rio Rancho
Location of Project: Rio Rancho, NM
Contract Amount: $8,796,959 (AUI Inc.’s subcontract amount)

The project called for a 3.1 mile extension of Paseo del Volcan from Iris Road to US 550 consisting of the addition of a two-lane roadway, drainage crossings, roadway intersections with traffic signals, three bridges, and the raising
of Enchanted Hills Boulevard.  Once again AUI was a subcontractor to Mountain States Constructors, Inc., the prime contractor for this City of Rio Rancho project. Under AUI’s $8.7 million subcontract, AUI constructed four bridges (two single-span and two double-span), a seven-barrel box culvert , a two-barrel box culvert , approx. 10,000 SF of soil nail walls , 3,000 SF of pre-cast sound walls , approx. 50,000 SF of MSE wall, and 2,000 LF of concrete barrier wall. AUI also placed over 2,500 LF of RCP storm drain ranging from 72” to 96” in diameter, in addition to 2,000 LF of 12” sanitary sewer and approximately 800 LF of 16” waterline.

This American Reinvestment and Recovery Act (ARRA) funded project began construction in August 2009 and was scheduled for completion by February 2011; however, AUI successfully completed its construction activities by the end of 2010.

I-10, Las Cruces to Texas State Line

New Mexico Department of Transportation (Owner)
Location of Project: Dona Ana County, NM
Contract Amount: $5,092,543.51 (AUI Subcontracted portion)

AUI was subcontracted by Mountain States Constructors, Inc. to assist in the new construction and rehabilitation of I-10 from Las Cruces to the Texas state line. The overall project scope involved the lane expansion of I-10 northbound and southbound lanes from two to four lanes. AUI’s portion of this project included the construction of a 4,800LF permanent concrete wall barrier, a new Gateway Sign for visitors entering the state of New Mexico, and construction of a 42,000SF precast concrete sound wall held in place by drilled piers. Scheduling conflicts were kept to a minimum as the project progressed smoothly with AUI placing over 13,000LF of culvert pipe extensions in addition to approximately 20 drop inlets of various sizes, to provide the necessary drainage for the lane expansion of I-10. The installation of culvert pipe and box culvert extensions; cleaning and or filling existing culvert pipe and box culverts; in addition to preparing the area for Mountain States paving portion by backfill and compaction over these installations, had to be done in an efficient and timely manner to assure that all contractors and subcontractors involved could stay on schedule.
AUI’s success on this project was dependent upon positive working relationships with both NMDOT and the prime contractor, Mountain States Constructors, Inc. The quality of the final project was enhanced by AUI’s commitment to the safety of their employees as there were no lost time accidents on the project and in large part to the dedication of our employees who take great pride in their work. Every effort was made to work together on this project and share resources when necessary; while efficient productivity allowed the project to stay on schedule and on budget.
