No crews were on-site this week due to post hurricane response. The new sod is doing well. The CIPP portion of the project is scheduled to continue on Monday, weather permitting.
The contractor spoke with the Insituform project manager, who informed us that they are not working on installing CIPP lining on their current projects this week due to significant damage caused by Hurricane Beryl to their facilities and job sites. They are focused on recovering and restoring their facilities, equipment, and job sites. Consequently, the CIPP installation will be delayed by a week, with the new expected start date being July 22nd. We have requested a written rescheduled proposal from Insituform, and they committed to sending it to us as soon as possible given their current contingency efforts.
Work has been at a standstill pending the arrival of CIP (cure in place) materials, which are tentatively expected to arrive by July 10th. The remaining repairs should only take a couple of days once the materials are received. Meanwhile, the construction crew has been watering the new sod daily.
Work on the sewer rehabilitation project is currently on hold due to a delay in the arrival of CIPP repair materials, which are expected to arrive after the July 4th holiday weekend.
At the end of last week, a crew was engaged in final sodding activities, which extended into the early part of this week. The crew also utilized a street sweeping machine to clean the streets and the driveway to the storage lot. They have removed all their trash and regraded the dirt in the area.
Another crew has been performing grouting on the new manholes that replaced the old ones. The contractor requested to vacuum test the manholes, but after consulting with Project Manager, it was decided that all testing should be conducted only after all repairs are completed.
This week, crews began removing old sidewalks by sanitary manholes 8 and 9 and the driveway around sanitary manhole 7 at the intersection of Village and Rio Grande. They poured the northeast quadrant of the north intersection of Rio Grande and Country Club, as well as sidewalks and a driveway by sanitary manhole 2 on the west side of Crawford and on the east side of Rio Grande, just south of Wall. They poured a sidewalk ramp at the north intersection of Rio Grande and Country Club and a sidewalk running north on Rio Grande. Rain interrupted work as crews were forming up sidewalks, though one crew continued to work on sanitary manhole 7 in the driveway at Village and Rio Grande, tying the residence service directly to the manhole. Finally, they poured two sidewalk ramps at the northwest corner of Wall and Crawford, the sidewalk adjacent to sanitary manholes 8 and 9, and backfilled the driveway at sanitary manhole 7.
This week, the northeast corner of Wall/Rio Grande pavement was demolished and removed. The crew placed sod in the area of MH 6 (manhole) and began forming up the sidewalk on Rio Grande to the south of Wall Street. The driveway near MH 4 was backfilled and made ready for forms. MHs 3, 8, and 9 were demolished and removed. The northeast corner of Wall/Rio Grande pavement was poured, and the sidewalk formed up. MH 3, 8, and 9 were replaced and backfilled. The driveway of MH4 was poured as well as the sidewalk on the north side of Wall St., east of Rio Grande.
The crew had several productive days this week. There are two joints left to complete the open cut replacement between manhole #5 and manhole #6, which should be finished by Friday at the latest. On Wednesday, the base of the new manhole #2 was put in place. Additionally, the sidewalk for the resident near manhole #1 was formed and poured.
The contractor has been granted permission to conduct work activities this Saturday 5/25/24.
The contractor did not work this past Saturday as the ground was still too wet. They are planning on working this Saturday, May 11.
Excavation and Bypass Installation:
Last week, significant progress was made at the lift station project site. The crew commenced with the excavation of the area designated for a manhole, which is necessary to install a bypass to facilitate work on the lift station. During this process, an abandoned pipe was discovered. A meeting with the engineer determined that the manhole placement could be adjusted to avoid interference with the abandoned line, allowing the excavation to proceed without complications.
Excavation and Trench Protection:
The crew continued with the excavation, implementing trench protection measures to safely reach the 36" line where the manhole would be installed. The line was located successfully, but subsequent rain on Thursday filled the excavation site with water. On Monday, well points were installed to manage and dry the groundwater, preparing the area for the installation of bull rock, fabric, and stabilized sand. This created a stable foundation for the manhole.
Concrete Pour and Manhole Installation:
On Tuesday, the lab supervised the concrete pour, which proceeded without issues. The "doghouse" manhole structure was then placed and left to cure overnight. On Wednesday, the lift station was temporarily shut down to allow for the stabilized sand to be placed. The crew then connected the manhole, grouting where the pipe entered, and the lift station was restarted by midday.
Backfilling and Completion:
The backfilling process began today, with the lab present to ensure proper compaction densities. The well points were removed, and additional risers were added to the manhole structure. Tomorrow, the top "cone" will be installed, and the final backfilling will be completed. The manhole installation is scheduled for completion by the end of the day.
As the contractor has not been able to work the last few days due to rain, they have requested the ability to work on Saturday. That Saturday work request has been approved. The contractor will be working Saturday, May 4, 2024.
Friday the crew completed Sanitary Man Hole (SMH) 6 and will be backfilling today. SMH has been excavated and they will be replacing it today and then do the open cut to replace the pipe between the two.
They also have another crew there today and they will be working on SMH 1, which is at the north side of Crawford at the intersection with Tahoe. They turned off the bypass from the manhole on south side of Rio Grande at Village to SMH 4 which is in the driveway of the residence on the NE corner of Rio Grande and Wall St. There is a good improvement in flow already.
This week the line locates were done so the contractor can begin their work. Work is scheduled to begin on Monday morning, April 22. Please be sure to check out previous updates to find the current schedule of events for the project.
On April 9 the City was provided with a Construction Schedule for the project. You may view that schedule in PDF Format here. It shows the scheduled dates and which streets will be impacted.
Work is scheduled to begin on Rio Grande Street on the week of April 22. This is the longest piece of the project, and is scheduled to take 16 days to complete.
The whole project is schedule to wrap up the week of June 3.
This schedule could change based on weather and other considerations. If the schedule changes we will post that here along with the other regular updates.
During the March 2024 City Council Meeting, the City Council awarded the contract for the project. The contractor has been notified and a Notice To Proceed is expected to be issued in April 2024.
