This project for the City of Westminster required improvements to both the Semper and Northwest Water Treatment Facilities.

J&T coordinated the work at both plants to maintain operation and water service, while ensuring that the contractor could continue work without downtime throughout the project. The water treatment facilities went through a Colorado Department of Public Health and Environment sanitary survey during construction. J&T worked diligently with the water treatment facility staff and the contractor to continue work on the project while maintaining the plant’s standards.

The inspection noted no issues related to the construction. The project received the 2018 CCA H2O Award for Plant / Pump Stations (Raw Water / Drinking Water) Projects.

J&T designed and oversaw the installation of a new waterline in the median of Sheridan Blvd. between 80th Ave and the slope east of Guitar Center just south of Turnpike Drive in Westminster.

This project was ultimately combined with another project that was installing a portion of waterline from 92nd Ave to the same slope east of Guitar Center, and installing new sewer line in traffic lanes from 92nd Ave to 80th Ave. J&T worked with the engineering firm that was responsible for that other project in a combined project management effort. This included combining schedules, budget management, vehicle and pedestrian traffic control plans, and submittal review.

As part of J&T ’s work on the project, detailed waterline isolation and service maps were created for City staff. This helped staff isolate sections of the line for the required night connections. It also helped them confidently maintain service to residents and businesses in the area throughout the project. During construction of the project, the City discovered that they were having difficulty maintaining water pressure. J&T coordinated with the City to test existing waterlines and review
portable water flowmeter placement, pressure monitoring information, and valves operated. Ultimately, to resolve the problem, J&T assisted the City with the installation of piping and a new pressure reducing valve and vault to connect pressure zones 3 and 1. This allowed for the isolation of other portions of waterline and added a safety measure throughout the project.

Due to the location of the utilities in the state highway, traffic control was a very important aspect of this project. Several utility connections, lateral line installations, and paving operations had to be completed overnight.

J&T provided design review, bidding, and construction management services for the reconstruction of 1,900 feet of roadway along 8th Avenue between 28th and 25th Streets in Garden City.

The 8th Avenue roadway was in poor condition and needed to be upgraded to serve the existing traffic as well as traffic from future developments in the area. This project involved abandoning an existing storm sewer and installing new storm sewer infrastructure along and across 8th Avenue. Services provided on this project include project management, project phasing, drainage & drainage infrastructure design review, pavement design review, coordination of utility location and or relocation, probable cost for construction and total project cost estimates, and development of bidding documents, contractor qualification and selection, review of construction drawings and technical specifications, administration of the construction contract as the owner’s representative, and construction management of the improvements.

This project received the “Best Use of Public Space Award’’ from Downtown Colorado at the Governor’s Awards for Downtown Excellence. The award recognizes outstanding projects in Colorado that demonstrate creativity in the face of challenges and which further downtown initiatives.

The Croke Reservoir Shoreline Stabilization and Huron Street Improvements project was a two-phase project.

Phase One included the rehabilitation of the Croke Reservoir shoreline and the creation of a unique park. This phase received the 2009 American Public Works Association, Award for Engineering; Construction Management for a Medium Sized Community. In Phase Two Huron Street was reconstructed between the intersections of 104th and 112th Avenues, including traffic signal upgrades and/or replacement, storm sewer upgrades and replacement, landscaping and streetscape upgrades, and waterline replacement.

Journey Ventures, LLC., retained J&T consulting to provide design and construction services for a slurry wall associated with an 85-acre aggregate mine site in Weld County.

J&T and Cesare provided daily construction engineering and materials testing services during the installation of the slurry wall as well as performing the leak test. The leak test passed and met the State of Colorado’s design/performance criteria.

J&T Consulting has provided on call engineering and construction management services for the Standley Lake Operating Committee since 2011.

Work has focused on monitoring and improvements for The Standley Lake Pipeline (SLP), which is 35,000 feet long and consists primarily of 48” diameter pre-stressed concrete cylinder pipe (PCCP), and also includes two reaches of 41” and 48” diameter carbon steel pipe. The SLP is the only source of raw water for the City of Northglenn’s water treatment facility.

We have provided on-call engineering and construction management services for the town of Superior since 2011. J&T manages the town’s annual street improvement projects.

The projects include repairing degraded roadway paving and concrete curb, gutter, sidewalk, medians, trails, storm sewers and drainage systems. We have also designed parking lots and a water quality pond and outlet structure as part of this work.

J&T provides capital project planning and prioritization, individual design and construction project management, project phasing, drainage design, pavement design, and surveying. We also coordinate with town staff and residents affected by the construction and with utility owners on accommodating or relocating utilities. As the City’s representative, J&T administers the construction contract and manages the construction of the improvements.
