We placed 48 hollow core concrete panels this morning. The first panel was lifted from the truck at 8:10 am and the last panel was put in place less than 4 hours later at 12:01 pm.
Also, Bryan met with a neighbor that needs a home for some virgin dirt, located only a few blocks away.
Yes, another big day.
One of our stated objectives for this project is to use ‘innovative building materials’. We are one of the first single family residential homes to use hollow core concrete panels in Northern California. We engaged Bill Brown Construction Company to partner with us on 17509 Via Sereno because:
- Bill Brown has extensive experience in all the areas that we need expertise (e.g., seasonal perched water tables, waterproofing, ‘green’ building design and construction, etc.).
- Bill wants to innovate and be a leader with new building products and new construction practices.
- Bill has a great team that can ‘do the hard stuff’ that he leads personally and, most importantly, has a passion for construction while having fun.
We wanted to get in front of the day so our plan was to assemble at 7:15, have the crane arrive at 7:30 am and get into position, and have the first truckload of hollow core concrete panels arrive at 7:45 am so we could start working at 8:00 am as we unloaded the first panel.

Chad extended the boom and confirmed the crane could reach everywhere in the site that was required. We’re good to go!
The First ‘Bay’ of Panels
Chad lifted the first hollowcore concrete panel from the truck at 8:10 am. Bill and Bryan were on ladders so they could position the first panel at the far end of the house, in the first ‘bay’.

We completed placing 18 hollowcore concrete panels in the first bay and were ready to place the largest and heaviest panels in the second bay.

Third Bay Blind
The entire team placing the hollowcore concrete panels were working well, and the difficulty increased. In the third bay, the crane operator (Chad) would have limited visibility as the feature concrete wall between the garage and kitchen would be blocking part of his view. As well, the first panel required Bryan to be on a ladder in the north-east corner of the house.

Although it was very close to the crane, placing the hollowcore concrete panels in the garage was a bit trickier. We had smaller panels and tighter spacing. Fortunately, Pete Janovich from Bill Brown Construction Company came by the job site and used his house-moving expertise to advise us regarding how to move the panels into final position easily, accurately and quickly.

The last hollowcore concrete panel was in position at 12:01 pm. This was quite a milestone!

A couple neighbors from Monte Sereno came by to see the progress we made today. Bill Brown discussed the project with them.
Moving Dirt in Monte Sereno
Another neighbor in Monte Sereno, Luis Allende, has some virgin soil at his project site only a few blocks away that we can use to backfill our excavation.
