Hillcrest Water Project Update – 9/30/2019

PROJECT UPDATE 9-30-2019

New Project Contact

Mechelle Little is the new communications contact with MWHC and will serve as the liaison for neighbors with construction questions regarding the Hillcrest Project onsite construction. Her contact information is provided below.

Pipeline Work

The installation of the new pipeline that runs behind homes along South Hillcrest Drive is nearly complete. The remaining section of 40 feet of pipe will be completed in spring 2020 after other construction activities in the area are completed.

Construction Progress and Stockpile Update

During the demolition of the existing concrete storage tanks, asbestos boards were discovered in a small area of concrete supporting the foundation of one of the tanks. As a safety precaution, tank demolition, stockpile removal and backfill work were halted. The issue was immediately reported to the Colorado Department of Public Health and Environment. Denver Water and MWHC isolated and covered the area of concern in accordance with CDPHE containment standards. CDPHE has given its approval to move forward with our sampling plan to test the backfill areas around the tanks.

Denver Water and MWHC have conducted the asbestos sampling and are working with CDPHE to review the final sampling analysis. Pending the results of the sampling, we expect tank demolition and stockpile backfill work to resume in late October to early November.

 

General Construction Hours

General work hours are 7 a.m.-6 p.m., Monday-Friday. Saturday work has resumed to help offset project delays. Personnel will arrive at 7 a.m. and equipment use will begin after 8 a.m.

Hillcrest Update

PROJECT UPDATE 8-21-2019

 Project Contacts

MWH is in the process of hiring a new communications liaison to replace Casey Corrigan. This person will serve as the liaison for neighbors with questions regarding the Hillcrest Project. Gianna Lombardi will be replacing Julie Seagren as your Denver Water contact. The updated contact information is provided below.

Pipeline Work

The installation of the new pipeline running behind the homes along South HillcrestDrive is nearly complete. The remaining 40 feet of pipe will be completed this spring after other construction activities in the area are completed.

Return of the Construction Crane

MWH is scheduled to bring back the large construction crane on Aug. 23 to help with the removal of a water tank on-site. The crane is anticipated to be on-site only for the day.

Construction Progress and Stockpile Update

During the demolition of the existing concrete storage tanks, asbestos was discovered in a small area of concrete supporting the foundation of one of the tanks. As a precaution, and to ensure the safety of our neighbors and workers, tank demolition and stockpile removal and backfill work was halted and the issue was immediately reported to the Colorado Department of Public Health and Environment. Denver Water and MWH isolated and covered the area of concern in accordance with CDPHE containment standards.

Denver Water and MWH are working with a third-party contractor specializing in environmental remediation to develop a sitewide sampling plan to confirm that the asbestos has been confined to its original location. We expect CDPHE approval of the plan within the next week and completion of site sampling and analysis over the next two months. CDPHE will review the final sampling analysis to ensure the site is safe before resuming work. Pending the results of the sampling, we expect tank demolition and stockpile backfill work to resume this fall.

General Construction Hours

General work hours are 7 a.m.-6 p.m., Monday-Friday.

No Saturday work is currently planned, but it will continue to be an option that MWH and its subcontractors will use when necessary to keep the project on schedule or at times when the additional work could result in condensing the overall construction timeline. Saturday work hours will be consistent with weekday hours, 7 a.m.-6 p.m

Water Board Update: 2-14-2019

PROJECT UPDATE 2-14-2019

Existing Basins Demolition – What’s That Noise?

The demolition of the existing basins officially began earlier this week. The additional noise you are hearing is the large equipment breaking apart the old structure. We anticipate the demolition activity to take approximately 8 weeks. As a reminder, there will be a strict dust mitigation plan in place and we will be monitoring both noise and vibration levels more closely to minimize as much disruption aspossible. There will be no demolition work outside of normal hours (Monday – Friday from 7:30am to 4:30pm).

Stockpile – When Are the Large Piles of Dirt Going Away?

Backfilling around the new reservoirs has begun. Good news! That means the stockpiles of dirt around the site will slowly be going away.  Please note that this is a slow process and is also weather dependent. Like other construction activities onsite, dust and noise are being monitored and dust mitigation is being used. We continue to appreciate your patience with these activities.

General Construction Hours

General work hours are 7:00 am – 6:00 pm, Monday – Friday.

Saturday work will continue to be an option the subcontractor and MWHC will retain and use when necessary to keep the project on schedule or at times when the additional work could result in condensing the overall construction timeline. Saturday work hours will be consistent with weekday hours 7:00 am – 6:00 pm.

Existing Basins Demolition

Demolition of the Existing Basins is expected to begin as early as next week (January 28th). There will be a strict dust mitigation plan in place and we will be monitoring noise and vibration to minimize as much disruption as possible. Please note, there will be no demolition work outside of normal hours (Monday – Friday from 7:30am to 4:30pm).

 

Stockpile

Work on the backfill of the new tanks continues. Due to the time of year and the possibility of inclement weather conditions, we anticipate the large stockpile along Happy Canyon Road to be gone by the end of March 2019. There will be increased truck traffic in mid-February as we start the backfill behind the retaining wall.

 

General Construction Hours

General work hours are 7:00 a.m. – 6:00 p.m. Monday – Friday.

 

Saturday work will continue to be an option the contractor and MWHC will retain and use when necessary to keep the project on schedule or at times when the additional work could result in condensing the overall construction timeline.
