Lift Station #6

We're working the last steps for the lift station 6 project, there are intermittent workers on site, and usual visits by City workers to operate the station.

The site is starting to look more like the project image. In the last month demolition completed on the old lift station, and seeding and tree planting was done. We're still working a few punch-list items inside the station. In the next month we will see paving, concrete and more finishing touches to the site, street, boulevard and nearby sidewalk.

The old station demolition is nearly complete. When the site dries out from the recent rainfall, there will be several utility installations and final grading will begin. Restoration including paving sidewalks, driveway, landscaping and seeding will take most of July.

Outside the station we're waiting for Xcel Energy to disconnect the former station from power, and then the demolition will begin.

Inside the station the contractor is putting on finishing touches. The station is up and running and we're working to seal and finish the spaces and test the equipment. Pictured is the overhead crane that is used to pull the submersible pumps for maintenance and repair.

Startup week is going well, and the end of construction is near. Here are the remaining steps and approximate times:

1. April - Startup of new station, connection of new pipes, demolition of old station starts
2. May - Demolition of old station finishes, final grading starts
3. June - Final grading finishes, driveway, sidewalk preparation, paving starts,
4. July - Paving and sidewalk finishes, final seed and landscaping

We're coordinating with a separate contractor for the related pedestrian connections and intersection improvements. We'll update with more details for those improvements when they are better known.

During the week of April 1, the new station will be programmed, tested and commissioned. The new station will run with the old station off, but available as backup as the operators train on the new station during the week and over the next weekend.

Following the testing and commissioning period, the old station will be demolished and final site utilities will be installed.

The old station served for 70 years!

Lot of action but nothing much to see these days, here's a summary of the work inside the station:

1. Insulation, roofing materials
2. Framing, drywall
3. painting, coatings
4. electrical, communications
5. plumbing, pumps

This week roofing, insultation and waterproof membrane are going on. Once the structure is water tight internal work such as dry wall and electrical can begin.

The station is going vertical this week and next with precast concrete panels, welding, pump lifting beam, roof truss installation, fence and electrical pad installation.

72nd and Cornelia is open: This intersection is being completed for the pedestrian safety project. Pavement is planned for Friday or Saturday this week.

72nd, Oaklawn and Claremore is closed to traffic and will be opened to pedestrians this week to prepare the the neighborhood Halloween Parade event this Sunday. This intersection is paved but there is a large hole just off the pavement on the site that is currently blocked with a variety of dewatering pipes that are supporting the deep pipe work on site.

This week on site there will be continued deep pipe installation work. Next week will include electrical transformer installation and shallow site pipework, and the beginning of the above grade structure if the weather cooperates.
