Gregory Hill Area Construction Projects

Gregory Hill Pipelines

For the past several years the City of Westminster has been coordinating the replacement of aging infrastructure in the area north of 80th Avenue and west of Lowell Boulevard. To date, work has included installation of new water transmission mains in Lowell Boulevard and Turnpike Drive.

Project Update - Jan. 17

The contractor has completed the installation of the new water mains and has completed making connections to existing water mains. The new water mains are now in service. The remaining work includes final paving, clean-up and demobilization by the contractor, which is scheduled to occur over the next two weeks. Replacement of the concrete pavement in the Lowell Boulevard and 80th Avenue intersection, which is scheduled for this week, will likely result in overnight road closures and detours to continue to be in place while the concrete cures. Revegetation of some of the disturbed landscaping will not occur until the spring.

Project Details

The next improvements involve construction of new water transmission mains to replace aging water systems that have reach the end of their useful life. The new water transmission main will be installed in 80th Avenue between U.S. 36 and Lowell Boulevard, then north in Lowell Boulevard to Turnpike Drive. New water and sewer mains will also be installed in Laplace Court from 80th Avenue to 82nd Avenue. (see map)

These new water mains will serve area residents and also the new Gregory Hill pump station and tanks planned as part of a phase later this calendar year. Information regarding the new pump station and tanks will be distributed later in the summer and will include an invitation to a project open house information session to be hosted by the City. Overall, these improvements are necessary to meet the level of service experienced elsewhere in the system for adequate water pressure, flow, redundancy and stored water available for irrigation, firefighting, and emergencies. Connections to the new water main will be sequenced to minimize service interruptions as much as possible. Construction is scheduled to start in a few weeks and will extend through to the end of the year. Check this website for regular updates during the project. 

Westminster City Council has awarded the project to Brannan Construction Company, a reputable contractor in the industry. Normal work hours will be Monday through Friday beginning no earlier than 7 a.m. and ending by 5 p.m. Special circumstances may arise requiring extended work hours. In these special cases limited nighttime or weekend construction could be necessary to avoid times of higher traffic volume. During working hours, construction equipment will be in operation and some materials may be stockpiled close to the work area. The Contractor will maintain traffic control during construction and will maintain access to side streets and parking lots as much as possible. However, temporary lane closures, sidewalk closures, and detours may occur. Safety of the pedestrian, biking, motoring public and of the contractor crews is of the utmost importance and assistance in abiding by all construction related signs is greatly appreciated.

Thank you for your patience during this capital improvement project. We look forward to maintaining a high-level of service for you now and into the future.

 

      

Gregory Hill Pump Station and Tanks Replacement

The city will replace the existing water pump station and tanks known as the Gregory Hill Pump Station and Tanks located near 82nd Avenue and Osceola Street.

Project Update - Jan. 17

Rough grading and subgrade excavation for the new tanks and pump station is nearly complete. Demolition of the old pump station building, the west steel tank and the buried concrete tank is scheduled to begin later this month after some electrical equipment is relocated. Also scheduled to begin later this month is the drilling for the piers that will support the pump station and new tanks. The contractor will continue to haul away excess materials that are currently stockpiled.  (See photos below).

A project webcam has been established link and will be used to create a time lapse of the project construction. The webcam provides an image that is updated approximately every hour.

Project Details

Overall, the work is necessary to replace aging infrastructure that has reached the end of is useful life span. The project will include system improvements to meet the level of service experienced elsewhere in the system for adequate water pressure, flow, redundancy and stored water available for irrigation, firefighting and emergencies.

Timeline

The replacement project is anticipated for completion summer 2019. The work includes complex operations that require a long-term construction period and mobilization of specialized construction equipment.

Project Impact

Due to the proximity of this project to our customers, the city is taking special precautions to minimize disruption and inconvenience, including: 

Hiring a specialty contractor with high qualifications specifically for this type of work. All contractors bidding this work completed a detailed prequalification process.
Restricting work hours to Mondays through Fridays from 7 a.m. to 5 p.m. to limit the impact of construction equipment and work noise. Weekend and evening work will only be permitted if special circumstances arise.

Careful monitoring of contractor compliance to state and local permit requirements for noise and dust control. Sequencing the work to minimize the need for water service disruptions. 

Information/Questions

For general questions, concerns or comments, please contact the city’s Project Manager Dan Strietelmeier, at 303-658-2179, or dstriete@cityofwestminster.us.
