Town Center Update - October 3, 2019

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.

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 - September 19, 2019

Atherton Town Center - Project Activity

Overall project work this week focused on finalizing the Police Department's temporary parking area; finishing work on the sewer laterals; continued work on the new water line; drilling and installing piles for the new City Hall/PD building; and excavation of the grade beams for the new Library building. 

Grade_Beams_LibraryThis is a very exciting time for the project! Batter boards are up and forming the perimeter of the new buildings and with the excavation of the grade beams you can see the shape of the new facilities. In the coming months, the buildings will go vertical and it will get even more exciting! The roadway entry for the temporary parking for the Police Department with access off of Fair Oaks is where that new road will enter off of Fair Oaks and cut over to Ashfield when the project is complete. That new roadway is still a naming opportunity that the Council is considering as part of the continuing fundraising effort.

City Hall/Police Building


For the new City Hall and Police Building this week, Amoroso finished up the temporary gate and fencing for the Police Department's temporary parking area. The drilling crew shifted from the Library to the City Hall pad to begin drilling and installing the piers. There are 105 total piers that will be drilled for the new building at varying depths.

Pad_Elevation_Civic_CourtYou will notice as you drive by that the pad itself is a bit elevated from the natural grade - particularly off of Fair Oaks. 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.

Pier_Drilling_City_HallAs Amoroso works on the piers for the building, they will also excavate the elevator. This is a two-story building and as a public facility, it requires an elevator to provide access to the second floor. The elevator is accessed from the lobby area and takes the visitor to the second floor pathway between the Building and Planning Departments on the west side to the Police Department on the east side.

As you 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.

Town Center Update - September 7, 2019

Posted on September 7, 2019 at 11:07 AM by grodericks grodericks

Overall Project Activity

Work this week focused on finishing the new sewer line and laterals, continued work on the new water line, installation of the final paving for the temporary roadway from Fair Oaks into the Police Department parking area, and drilling of the piers for the new Library. 

Live webcams for Library site work and the City Hall/PD site work are now active on the Town's website. There is also a project progress photo gallery

City Hall/Police Building


PD Parking AreaS.J. Amoroso this week finalized the roadway from Fair Oaks into the secure Police Parking lot. Parking for the Police Department has to be relocated as work on the new building moves forward. 

S.J. Amoroso also completed finish grading for the new building pad. Once the finish grade was certified, S.J. Amoroso began installation and layout of batter boards and will begin drilling for the building piers. There are 105 drilled piers for the Admin/PD building. Once the piers are drilled and installed, S.J. Amoroso will begin excavation of the elevator pit and layout and excavation of the grade beams for the building. 

Adjacent to the main City Hall and Police Building is the new Secure Police Parking Lot. Within that lot (between the new building and the Caltrain tracks) is the Police Ancillary Building. After finalizing the main building pad, S.J. Amoroso will finalize the pad and layout for the Ancillary Building. 


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. The front doors of the entry way area are being saved and refinished for reinstallation at the end of the remodel. 

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. 

New Library

Library PadWork this week continued with drilling and installing the piers for the new building. There are 64 piers for this building. There were several issues encountered that have caused a slight delay in moving forward. These were quickly remedied.

Once the piers are complete, work will begin on layout and excavation of the grade beams and installation of the rebar. At this point, you should be able to see the layout of the new building taking shape. 


Site Work

Overall site work was focused on utilities. The new sewer line work completed. CalWater is on site working to finish installation of the new water line.
