New Driveway Bridge In Oakland Hills

This newer driveway bridge has failed because of improper waterproofing

Dry rot in the framing could result in a serious failure over time

The wall below the garage door was seriously rotted needing replacement.

We rebuilt the bridge with new structural framing. After the big Oakland Hills fire the new code required all bridge rebuilds to be engineered for firetrucks to be safe to park or turn around on them.

Proper waterproofing starts with new metal flashing at the borders

New 1-1_8_ plywood is installed for the deck, along with a bituthene membrane for waterproofing.

A strip drain (AKA drain channel) is installed adjacent to the garage door to keep water out of the garage.

Extreme rebar is part of the engineering. 1_2_ rebar at 4_ spacing one way, 6_ the other way.

The finished product. The stucco used had integral color to match the house. To get it to look good we had to refinishe the entire wall on either side. — The finished product.

The final product looks like new. No those are lights not holes.

Driveway Replacement in Piedmont

This driveway replacement is ready to pour. Note the drain channel to keep water out of the garage. There is also a French Drain in the planting area (middle left) to ensure water stays out of the adjacent basement.

We spent time with the client to layout a pattern for the lines that we agreed on. We also did a wash to the finish to create some texture to make the driveway look a little older and also less slippery

Basement Digout:Remodel- Mandana

Covid postings at the entry point of projects is one of several elements of the new protocol.

Ibeams were installed to support the living room above the garage so the foundations could be removed.

Lots of dirt to takeout, 200+ tons over a few months

We can dig it

Moving dirt and concrete with the Bobcat

Rebar and formwork are being installed for the basement walls

Trenches are shown here for the foundations at the back of the garage

The garage is around 3 feet lower than the rest of the basement, requiring retaining walls around it.

Key supports need to remain in the slab, to be filled in when walls are built in those locations

The slab for the basement and slab for the garage with new concrete to be finished

NOW

The foundation walls have been sealed for waterproofing, with pressure-treated lumber added onto them. Rigid insulation will go in between.

The interior walls have now been installed

Windows are being installed. Areas of dryrot adjacent to windows and doors are also being repaired. It is common to find this type of damage in older homes.

With the wall framing now finished, plumbing and gas lines are being installed.

Archways have been framed ofr the openings in the living room, dining room, and family room.

Interior sheerwalls for seismic stability are complete.

Insulation is now done,. Water resitant insulation panels are installed on the foundation walls.

Sheetrock is in, preserving the original wood beams in the living room.

New wood beams are installed in the family room ceiling to mimic those in the living room

Living room dining room archway is complete

Master floor tile is in, being prepped for plaster walls

Lower bath is now prepped for tile

Extreme Basement Renovation, Remodel and Addition- Grand Lake, Oakland

This side of the basement is being dug to 11′ to create a music room

To create access to this new basement job we went in from the street and under the porch on the side of the house

As we progress with the excavation we are install steel Ibeams in key locations to support the house above.

The digout is becoming deeper and more extensive.

Multiple steel beams (seen above) were needed to support this deep digout where we are creating an 11′ ceiling. We have installed a waterproofing membrane along the left side.

Footings are being dug for the massive retaining walls. Temporary reinforced concrete supports were installed at the 3 story brick fireplace to support it during the digout.

Adding new beams to support the house during excavation of the second section.

Cleanouts for the new French Drains are put in place prior to the pour.

Drainage for the retaining wall is being installed from the inside out to avoid an additional exterior excavation after concrete. Our sometimes problematic clay soils carve out perfectly to allow us to create a notch for the pipe.

Formwork and bracing for the first section.

More Drainage.

Rebar has been installed for the section portion of the first section.

The initial concrete pour focused on one wall of the first section of the basement. Given the 3 story chimney and proximity to the neighbors it seemed prudent to get this wall poured ASAP. The bracing for the new wall pour was substantial.

The new wall after the pour before form removal.

The rest of the basement excavation is nearing completion. The second half will have typical 8_ ceilings versus the 11_ ceiling for the studio.

The second section has the old 3 story brick fireplace remaining. We have been adding underpinning in sections so it can remain supported in place without moving.

Preparing the rebar for the second half of the foundation

The footing will get poured first, with rebar extending up into the wall for the secondary pour.

The wide footing for the new retaining walls is required to prevent settling, overturning and sliding of the new structure.

Overview of the second pour footing

The exterior walls are completed and internal foundations are bing done. In the center will be a new retaining wall where the back level steps down to the music room.

The retaining wall for the external stairway are being built here
