Historic Town Hall

Demolition of the interior of the historic Town Hall building is complete. This building will ultimately become a part of the new Library connected via a deck and french doors that spill out from the side of the building onto the new deck. 

Work on this building will be sealed up for the winter season as work continues elsewhere on the project site. Once the interior work begins, work will resume on the historic Town Hall building.

Library Building

Library Main Wall EntryMost of the work this week focused on the forms for the Library foundations and walls. You can certainly see the Library taking shape. Work also continued moving in the underground plumbing to the building.

In the image to the right, you can see the main wall angling back to the historic Town Hall on the right. Atop this wall will be the entry doors into the children's area from the deck. The gap between walls on the left of the image is the entry ramp going into the library. You can see both in the rendering below. 
Library Rendering
Amoroso is also working on the mock up of the rammed earth wall that will traverse the east wall of the new Library. 

Site Work

Site work this week continued to focus on utilities as the contractor works out issues related to undergrounding of the utilities, the SFPUC water line, water and sewer. Storm drain work is also continuing. Once all this underground work completes, Amoroso can seal up the holes and the buildings will begin to go vertical.

We expect the foundations to be complete and concrete slabs to be poured by the end of this year. After that, steel will begin its installation as the buildings go vertical.

Town Center Update - October 17, 2019

Atherton Town Center - Project Activity

36-Inch_SFPUCOverall project work this week focused on finishing up the new water line installation, beginning work on the underground electrical, layout and excavation of the grade beams at City Hall, forming rebar and placing pile caps, installation of rebar and cables, and finishing up underground plumbing.

Site utility work is challenging as we have encountered numerous issues with existing (active and abandoned) underground utilities across the site. All known utilities were identified and marked; but, there continues to be a lot of unknowns that have been encountered on the site due to its uses over the years...and even, some fairly significant active utility lines that are simply not where they are supposed to be...like this 36" SFPUC Water Line.

City Hall and Police Building


For the new City Hall and Police Building this week, Amoroso finished up the layout and excavation of the grade beams as well as the layout and excavation of the elevator pit. Crews also began forming rebar and placing notches and pile caps. This excavated area leads toward the elevator pit from "under" the new Police offices.

The elevator pit is on the left side of the Lobby as you enter off of Fair Oaks. 
Elevator_Pit

Looking at it from the front doors of the lobby area, the elevator is to the left and straight ahead you would exit the site to the Civic Courtyard. The left side of the building is the Police Building areas.

Historic Town Hall

Demolition of the interior of the historic Town Hall building is complete. This building will ultimately become a part of the new Library connected via a deck and french doors that spill out from the side of the building onto the new deck. 

Work on this building will be sealed up for the winter season as work continues elsewhere on the project site. Once the interior work begins, work will resume on the historic Town Hall building.

The image here shows where the new library ends on the left with the rebar (the library entry areas). The deck area will extend to the right and back to the historic Town Hall which will become a multi-purpose room for the Library and Heritage Room. The two windows will be converted to french doors that will open onto the new deck. The room to the right of the two windows is designated as the new mini-cafe space. The space will be plumbed for a future mini-cafe, but an operator has not yet been identified.

Library Building

Work this week focused on the installation of rebar for the pending concrete pour. A second pour will occur next week after the rebar curbs and stem walls are completed.

Library_Concrete_Pour_1
Amoroso will also begin work on a mock up of the rammed earth wall that will traverse the east wall of the new Library. You can see the curved rebar traversing back into the site on the left of the concrete truck. This is the exterior rammed earth wall of the Library. Take a look at the Project Webcams and you'll get a good feel for what the shape of the final building will be and how it relates to the project site. 

Site Work

Site work this week still focused on utilities. While the main sewer line is complete, laterals needed to be added. Storm drain work is also continuing. CalWater is onsite to complete the new water line for the project as well as West Bay Sanitary for their connections. Once all this underground work completes, Amoroso can seal up the holes and the buildings will begin to go vertical.

We expect the foundations to be complete and concrete slabs to be poured by the end of this year. After that, steel will begin its installation as the buildings go vertical.

Town Center Update - October 3, 2019

Posted on October 2, 2019 at 11:48 AM by grodericks grodericks

Atherton Town Center - Project Activity

Batter BoardsOverall project work this week focused on storm drain installation, drilling and installing piles for the City Hall and Police Building, pile caps for the Library, and grouting and wrapping the embeds for the footings on the Library. 

When you view the site, you'll see a series of "batter boards" up around the footprints of the new buildings. Batter boards are temporary frames that are set beyond the corners of a planned foundation at precise elevations. You can get a rough layout of the building by looking at the batter boards. 
batter-boardsThe batter boards are typically set outside the corner stakes of the building. There's an image below that shows the batter boards and the Mason's lines for the Library Building. The batter boards for these buildings are set approximately 4-5 feet beyond the edges of the actual building. Finished floor elevations are above the batter boards by another 8-12 inches.

The total Town Center site is set on approximately 5 acres (219,425 square feet). The footprint of the existing buildings occupied approximately 26,000 square feet distributed across the entire site. There was another approximate 25,000 square feet of restricted and enclosed space for secure police parking, police facilities, and the corporation yard. The remainder of the site consisted of roadways, parking, and open space. There were a total of 122 parking spaces throughout the site (not including the Caltrain parking spaces along the rail corridor). Town facilities (buildings and enclosed spaces) occupied approximately 23% of the entire site area.

With the redesigned site, the footprint of Town facilities (buildings and enclosed spaces) occupy approximately 17.5% of the entire site area returning nearly 13,000 square feet to general public use. Further, the prior site had a significant amount of parking behind City Hall that was used intermittently for construction parking overflow and overnight parking - but overall, rarely used. Based on a site use analysis that evaluated time of use and need based on the types of activities at the site, the parking was reduced to 58 total public spaces (plus the parking spaces in the Caltrain corridor). This resulted in a return of another approximate 10,000 square feet to general open space. Overall, the redesigned site will return approximately 23,000 square feet of hardscape to landscaped open space.

City Hall and Police Building


For the new City Hall and Police Building this week, Amoroso continued work on drilling and installing the piers for the building. There are 105 total piers for the new building at varying depths.

The entry into the building from the Fair Oaks side will include a ramp and a small set of stairs. As you cross the site, the difference in elevation of the pad to natural grade decreases as the natural grade elevation increases. This difference in grade is not something you may have noticed on the original site, but in order for the new Civic Court to daylight out to natural grade near the historic Council Chambers the pad ends up higher on the Fair Oaks side of the project.

As yoSecure PD Parking and Ancillary Buildingu look at the pad from Fair Oaks, to the left you'll see part of the existing roadway that's maintained at the present time. Under this section is the large 36-inch CPUC Water Line. Design and work on this project had to protect that line in place as the CPUC refused to relocate the line as part of the Town's project. This not only put constraints on the design but also causes construction challenges. To the left of the CPUC water line is the pad layout for the Police Department Ancillary Building. The water line traverses the Police Department's new secure parking lot which is west of City Hall. 


Historic Town Hall

Demolition of the interior of the historic Town Hall building is complete. This building will ultimately become a part of the new Library connected via a deck and patio doors that spill out from the side of the building onto the new deck. You can see the layout of the new patio and dec in front of the grade beams currently excavated for the Library. 

Work on this building will be sealed up for the winter season as work continues elsewhere on the project site. Once the interior work begins, work will resume on the historic Town Hall building. 

Library Building

Library LayoutWork this week focused on the pile caps and grouting and wrapping the embeds on the piers. You can see the Mason's lines attached to the batter boards that frame up the exterior wall locations for the new building. 

As the line moves back toward the Historic Town Hall, it meets at two existing windows. These windows will be removed and replaced with a pair of french doors that will lead out from the community room (old Council Chambers) onto a deck that extends to the right of the Mason's lines visible in the photo. 

Take a look at the Project Webcams and you'll get a good feel for what the shape of the final building will be and how it relates to the project site. 

Site Work

Overall site work this week still focused on utilities. While the main sewer line is complete, laterals needed to be added. Storm drain work is also continuing. CalWater is onsite to complete the new water line for the project. Once all this underground work completes, Amoroso can seal up the holes and the buildings will begin to go vertical.
