Concrete is being poured on the south side of the building for the solids contact clarifiers and the lime sludge basins. Several loads of precast walls and hollow core panels were installed in the last month. Here is a photo looking down in the filter area and you can see the 100' long precast double tee sections which span this area.

All of the flooring in the garage was placed along with the diesel tank for the new generator. This week the precast walls of the north half of the building were erected. The high service pumps and much more process piping was installed and precast hollow core flooring was set for a portion of the operations level.

The plans and specifications for the bridge are nearly complete. The City will begin advertising the project for construction next week with a bid opening at the end of August. At part of the road re-alignment, Lair Road was closed earlier this week so City's crews could work on the water service for the Channel Inn. Construction for the new bridge is expected to begin sometime in September. The City's construction page has a image of the new alignment of Lair Road and the location for the new bridge.

This precast installation will continue for the next two weeks until the vehicle garage area is fully enclosed around the back-up generator that was set earlier this week. In other portions of the site, the filter walls are being constructed. Those are the high walls beginning to extend above grade. Also, process piping is being installed in the subgrade level. Below is a picture of some of the process pipe installation from earlier this week.

Subgrade walls continue to be formed and poured. It is anticipated that all subgrade walls will be complete by the end of next week. This picture shows the shoring and decking currently being placed in the northwest corner of the clearwell to prepare for installation of the gallery level floor. The grading contractor will be back onsite soon to begin backfilling sand on some of the subgrade walls.

Concrete is continuing to be placed with at least two pours a week. Generally, one pour of concrete is 50-75 cubic yards. The interior walls of the subgrade level have begun to take shape. Those of you who are able to visit the site can see quite a maze of walls in the clear well area.

At the end of January, Wells Concrete began production of the precast wall panels for the new WTP. Last week several of us visited Wells, MN and observed the process they use to construct precast walls and beams. I have attached a photo of one of the first ones to be completed. Wells will also be casting several double-tee beams for the roof of the new plant later this summer.

After taking the week between Christmas and New Year's off the contractors are back to work. The weather has cooperated up until today as temperatures begin to fall and the talk of snow is in the forecast. Yesterday about 70' of wall was poured with another concrete pour scheduled for Friday of this week. Material continues to arrive and is being stored on-site. Some of the material includes, steel rebar, ductile iron piping, ductile iron pipe sleeves, and other miscellaneous pipe fittings.
