for the US Army Corps of Engineers at Holloman AFB

The Bonito Pipeline, located in southern New Mexico, provides raw water from Bonito Lake outside the Town of Ruidoso to the City of Alamogordo and other small communities along the way. Once treated, the water supplements the water supply for the City of Alamogordo and Holloman Air Force Base. The project entailed replacing a 55-mile plus portion of deteriorated 16-inch and 20-inch diameter concrete cylinder pipeline with new 14-inch through 20-inch SDR-18 and SDR-25 PVC pipe. The construction flanked State Highway and Union Pacific Railroad (UPRR) right-of-way, ran through residential neighborhoods, under several arroyos and crisscrossed the highway and railroad.

The more challenging aspects of the project included, working in close proximity to the active pipeline, working next to the railroad, and through the arroyo crossings. Working adjacent to the railroad required constant coordination between AUI and UPRR to ensure that all construction personnel and equipment were moved beyond the clear zone each time a train passed through the work zone. The arroyo crossing at Temporal Creek required an excavation 35-feet deep and roughly 200-feet in length in order to protect the pipeline from scour. The volume of soil excavated created spoil piles stretching sometimes two-hundred feet behind the active work zone and requiring constant monitoring to control dust during periods of elevated winds.

In February of 2004, the United States Air Force Air Combat Command honored AUI Inc. with a Construction Excellence Award for this project stating that the project exceeded ACC's expectation for excellence in cost, schedule and quality control.

for the County of Los Alamos

The North Road Reconstruction project was initiated due to the "Cerro Grande Fire" in Los Alamos County and the extensive damage to the local watershed. The mountainous forest that suffered the fire could no longer naturally handle the runoff associated with normal seasonal rainfalls and severe damage to North Road resulted. The basic premise of this project was to rebuild North Road with enlarged drainage structures over Pueblo Canyon and Pueblo Tributary Canyon. In the process of rebuilding the washed out roadway, extensive utility relocations were required including several thousand lineal feet of trunk water main.

for the City of Albuquerque

This project is part of a series of contracts that will bring Rio Grande river water to a purifying station where it will become a much-needed supplemental source of drinking water for the City of Albuquerque. It consists of furnishing and installing over 1,285 LF of 60" and 3,723 LF of 54" high pressure welded steel pipe with 54" butterfly valves in two reinforced concrete vault structures. This project begins on Sequoia Road west of Alamogordo Drive, continues east on Sequoia Road down the west bluff, and crosses the Rio Grande at the west end of Campbell Road. The pipe installation beneath the river will included a temporary diversion of the Rio Grande, dewatering of the trench through the bosque and the river, asphalt and concrete removal and replacement on Sequoia Road and relocation of an existing 8" waterline.
