Update from January 18, 2024

December/January Progress:

Construction of the new Town Hall facility continues to advance.  Alten Construction and their subcontractors are pushing through the inclement weather and making progress in a variety of areas.  The roofing structure is complete except for the specialty roofing area between the building’s seismic separation.  Once the roof is complete, the solar subcontractors will install the solar panels on the roof structure and install the battery back up components.  

The entry/exit doors and perimeter windows have been installed in preparation of the siding components. The contracting team recently applied horizontal siding along the entry ways and other areas of the building.  Weatherproofing and stucco lath/mesh was applied in anticipation of the scratch coat (1st coat) of stucco material, which was installed last week.  Additional stucco layers including the finish coating will be applied in the coming weeks.  

The electrical contractors are on site daily and are implementing the comprehensive electrical, Audio/Video, and IT related electrical infrastructure.  PG&E returned to the job site this week and pulled power to the building allowing the contractor to energize the building when they are ready to do so.  

Alten Construction has deployed a number of heaters and dehumidifiers in the building to help eliminate moisture and dry building materials in anticipation of the interior work.  The installation of insulation throughout the building is complete. Fiberglass insulation has been installed in both the first and second story walls and ceiling.  Over the last two weeks, the contracting team installed the sheetrock/gypsum throughout the building.  The application of mud and tape will follow in the next few days.  Once the sheetrock, tape and mud components are complete, the surfaces will be prepped for the texture and interior paint. Interior trim, flooring and tile will then be installed towards the end of the build. 

Additional site work is underway including small retaining walls, curbs, and access ramps.  The plaza area has been sealed with weatherproofing and is awaiting the arrival and installation of pavers.  Additional updates will be provided in the upcoming weeks, but in the meantime, enjoy the photos below documenting the current progress and beautiful design of the Town Hall Facility.

Update from December 5, 2023

November Progress:

Since our last update in early November, Alten Construction has continued to make good progress on our Town Hall facility. A lot of progress has been made in a variety of areas.  The contracting team is nearly finished with the  comprehensive roofing structure, and roofing shingles were applied earlier this week.  Once the roof is complete, skylights will be added in the east wing-Town Council Chamber.  Facia trim and eve work is currently under way, while our gutters have already been installed.

Various flashings and weather proofing materials have been applied throughout the exterior surfaces in anticipation of the stucco and siding finishes. Our electricians are finalizing the rough wiring, while our fire alarm contractor is expected to begin their component in the very near future.  The majority of the data cable has been pulled throughout the building, however, additional wiring and finish work will continue in the coming weeks.

Our electrical contractor will be setting/placing the facility's Main Switchboard and transformer in anticipation of our collaborative work with PG&E scheduled for Friday December 16th and Saturday December 17th.  Our contracting team has approval and the Town's permission to work with PG&E on that weekend to supply power to the facility.   During that weekend work, Alten Construction and our electrical subcontractor will pull primary and secondary power feeds to our MSB and work with PG&E to energize our building.  AT&T is scheduled to install telecom service to facility by the end of December.  Following the completion of the Mechanical, Electrical and Plumbing rough-ins, the gypsum/sheet rock subcontractor will begin applying sheetrock throughout the interior.  Sheetrock is scheduled to be delivered within the next week or so.

Alten has spent significant time on our plaza area working on the comprehensive design and applying weatherproofing in anticipation of the finish pavers. Additional hardscape has occurred with several concrete pours for retaining walls, slabs for equipment, curbs, and access ramps.  More to follow in the upcoming weeks, but in the meantime, enjoy the photos below documenting the current progress and beautiful design of our Town Hall Facility.

Update from November 1, 2023

October Progress:

Since our last update in early October, Alten Construction has continued to make good progress on our Town Hall facility.  Over the last few weeks, the contracting team has continued to work on the comprehensive roof structure. Fire sprinkler lines have been plumbed through the roof structure and closed cell insulation was installed/sprayed between the roofing joists.  The contractor has continued to implement temporary winterization measures over the past month but as of this week has begun the final roof sheathing, which will be followed by permanent weatherproofing measures.  This week our contractor has begun sheathing the roofing structure and weatherproofing will follow upon completion of the sheathing.  

Most windows have been installed and flashed with the weatherproofing pending on the exterior in preparation of the siding material.  The interior framing work is complete and sheetrock has begun in some areas. Progress is made daily on the Mechanical, Electrical and Plumbing (MEP) and Town inspections are occurring regularly. 

The utility preparation work that necessitated the closure of Willow Ave for the past few weeks is nearly complete. We anticipate the remaining work to be completed in the next couple weeks.  When it's safe to do so, the Town will re-open the road for vehicular traffic.  Our  construction team is working with local utility providers including PG&E and AT&T to relocate our power pole and establish utility services to our Town Hall Facility.  

Some hardscape framing and concrete pours have occurred and additional concrete pours are scheduled regularly.  Work continues in our plaza area which is really beginning to take shape.  More to follow in the upcoming weeks, but in the meantime, enjoy the photos below documenting the current progress and beautiful design of our Town Hall Facility.

Update from October 4, 2023

September Progress:

Since our last update in early September, Alten Construction has continued to make good progress on our Town Hall facility.  Over the last several weeks, the contracting team has focused a lot of effort on the comprehensive roofing structure.  You'll see from the incorporated photos that the roofing system is made of several layers and surfaces.  Our fire sprinkler subcontractor is actively installing the necessary fire sprinkler piping into the roof system.  

The interior framing is nearly complete with next steps involving sheetrock and other interior surface installation following the completion of (MEP) Mechanical, Electrical and Plumbing rough-ins. Progress is made daily on the (MEP) rough-ins and Town inspections are occurring regularly.  Our electrical contractor is currently installing the rough-in electrical in the first story roofing system which involves mapping out lighting configuration.  You'll see from the incorporated photographs that the scaffolding arrived last week and is fully installed giving workers the ability to focus on the exterior surfaces, including sheathing, windows and the pending siding surfaces.  Window installation began late last week and will continue in the weeks to come until the structure is fully closed in.  Alten Construction performed the saw cut and subsequent excavation into Willow Ave to prepare for PG&E utilities for the building.  The current road closure on Willow Ave, and associated traffic/neighborhood impact will remain in place for approximately six more weeks, or until the utilities are in place and the road conditions are safe to reopen.   

More to follow in the upcoming weeks, but in the meantime, enjoy the photos below documenting the current progress and beautiful design.

Update from September 7, 2023

Late August/Early September Progress:

Since our last update in mid-August, Alten Construction continues to make good progress on our Town Hall Facility.  Over the last few weeks, the contracting team has focused significant efforts on the comprehensive roofing structure.  The contracting team is making great progress on the roof system as evidenced by the incorporated photographs of the west wing.  Please take note of the first photograph in this update which was provided by the project architect, Ron Kappe, of Kappe Architecture.  It's a little difficult to see in the photo, but if you look closely, you'll notice the roof pitch design matches the natural flow and shape of Mt. Tamalpais in the back drop!

Look Ahead Schedule (February & March):

  • Once the concrete foundations have had a chance to cure, the forms will be stripped and waterproofing and drainage measures will be installed on the back side of each of them. 
  • Temporary shoring will also be utilized as a time saving measure to support the new retaining walls as they cure and reach the needed concrete design strength. 
  • This will allow for backfill of soil behind them and further erection of the structural framing for the building.
  • Steel columns and horizontal beams will start to be erected in early February and will continue through the month of March.
  • Also, the utility conduits and plumbing for the first floor slab will be prepped in March in anticipation of the concrete deck pour.

Update from December 1, 2022

  • Grade beam and footing work will continue to prepare the perimeter and other critical structural supports for the new foundation. 
    • Rebar is currently being placed for concrete grade beams and footings, with concrete pour expected the week of 12/5.
