Completed Concrete Haunch and Rebar in Swimming Pool

Friday, November 21st, 2008

The forms came off the concrete haunches today and they look good.

Next step is for the steel I-beams to arrive and be placed on the concrete haunches.

Meanwhile, Michael Benison’s team was rockin’ with the rebar in the swimming pool.

The workers would bend the #3 rebar (3/8 inch in diameter) with a special tool that they have.  This is exactly how the rebar will need to be bent at a 90 degree angle once the hollow core concrete panels are in place.

My friend, Roshan, dropped by the job site to inspect the project.  He thought it was going well and approved the work (so far).

Pouring Concrete into Haunches and Completing Plumbing Rough-In for Pool

Thursday, November 20th, 2008

Bill Brown’s team and Michael Benison’s team continued to work in parallel on site in complete harmony.

Thanksgiving is approaching rapidly and, as they say, ‘pressure makes diamonds.’

Pouring Concrete into Haunches

There was a small pumper truck for the haunches. Everything was set up nicely and the pouring was completed.

Michael advised me to move the inspection well to the north side of the pool (from the west side). This allowed us to take advantage of the existing excavation.

Next step is for the City of Monte Sereno to inspect the plumbing rough-in and the rebar in the swimming pool.

Forming Haunches to Support Wall and Re-Shaping Pool

Wednesday, November 19th, 2008

We have two activities going on in parallel – Bill Brown’s team is making the forms for the five concrete piers that will support the existing walls; and Michael Benison’s team is re-shaping the swimming pool.

Concrete Forms

The five piers that will support the I-beam that will, in turn, hold the existing walls in place need to be formed above grade. This required making the forms out of sono-tubes and building the custom rebar cages.

The City of Monte Sereno made some changes to the plans for the rebar cages.

Drilling the Final 5 Piers to Support Our Walls

Wednesday, November 12th, 2008

Of the 25 concrete piers that are required, 5 of those piers will support steel beams that will, in return, support the existing walls of the house.

All of the piers have been completed, except these final five piers. Until now, the rebar cages have been 30 ft long, now the rebar cages are 38 ft long.

More rain is forecasted so today is (another) big day.

Statutory Holiday; Bill Brown and Madalen Closson Visit the Job Site

Tuesday, November 11th, 2008

Since Veterans’ Day is a stated holiday in Monte Sereno, no construction activities could take place on November 11. I was busy quietly putting the HDPE tubing into the remaining five 38 ft rebar cages and several people visited the site.

Bill Brown, who lives nearby, saw the gate was open so he stopped by to check on progress. At the same time, our good friend Madalen Closson happened to be driving by and she stopped in for a quick peak at our progress.

Continuing to Drill, Drop and Pour

Thursday, November 6th, 2008

The weather was cooperating and it was a great day to be drilling the piers.

You can see the details of the rebar cages and the HDPE geothermal tubing coming out of the cages, protected by the flexible insulation.

Of course, after the pumper truck and everyone else left the site, the ‘real’ inspectors arrived! Jo-Anne, her mother, Dode, and Wendy Watkins came to the site and reviewed the progress.
