Hurricane Charley Roof Construction Project
July 31, 2005 Update
This report is being written on the 31st of
July, however it pertains to activities from the 27th and 28th.
I will start with R. l. James first. Walkways 9 and 10 have been sloped and
waterproofed. Another tile crew will be on site Monday morning to start
tiling one of those floors. The first tile crew worked Saturday to finish
tiling the 11th floor, will grout the floor on Monday and move to the other
waterproofed deck. Thursday afternoon John Z. and I inspected the remaining
walkway floors for crack chasing and concrete repair items. These are now
ready for final repairs, surface preparation and waterproofing. Bob James,
owner of R. L. James, Inc. was at the meeting and after looking at the 11th
floor commented on how good the floor looked. He said it was "awesome
looking".
There was a project meeting Thursday morning with the majority of discussion
centered around the coordination of use or lack of between the two
contractors. It appears the north climber will be moved this coming week to
the 37 riser to commence tile removal. Monday, John and I should be able to
perform the pre-pour inspection and quantity take-off on the 34 riser. To
date, all exterior mounted shutters have been removed from both penthouses
and the screen enclosure for Penthouse 2. Penthouse 1 is starting to remove
their tile and as yet do have permission to remove their sliding glass
doors.
Regarding the windows, John Dahin has sent out a contract to KNZ for windows
and install and has received the signed version back. I should be receiving
the window and shop drawings via FedEx Monday to begin review and
processing. As I will be out of town a week from Monday, this submittal will
be turned around this week. I've been told by a number of individuals at
RL's office that the window is still open for the delivery and installation
to coincide with the restoration contract.
Now to West Coast Roofing. I was informed Friday to contact Service Painting
to schedule themselves to finish prepping and painting the gable walls of
the two penthouses. If you recall, we held out some money from their last
payment application to come back and finish painting those walls and West
Coast doesn't want them on the new roof panels. West Coast had some problems
with the high reach from Sun Belt so they ordered a slightly larger piece of
equipment from another equipment rental company. Both upper flat roof decks
have been stripped and covered with the torch-down smooth surfaced base
sheet. You can observe quite a bit of corroded conduit penetrating the
existing slab surface. As the contractor began to remove the roofing at the
lower mechanical deck, they found this deck to have the original
light-weight insulating concrete. I observed the condition of it with Scott
Otey VP and everyone agreed that since there was no evidence of water
intrusion into the concrete, we would use it as a base for the new roof
system. There will be a deduct change order for not removing the deck sub-strate
in this area. There is slope on the deck and some modifying would be
required at the roof drain to lower the drain about 2 inches. We uncovered
an overflow scupper that had bee covered over some time ago - this we will
have Avis Plumbing rework to empty out through the soffit.
The procedure shown in the photos includes stripping the old membrane off
the lightweight concrete. The concrete is then cleaned off of debris and
dust and chalk lines are set as guides for the sheets of Dens Deck Prime
(the gypsum-based based green finished sheet for the new roof system). The
Dens Deck is attached using a two part structural foam adhesive. It comes
out of the mixing nozzle as a yellow liquid and within 30 seconds starts to
expand. The Dens Deck is placed over the adhesive and pressed lightly. In
five minutes it is set and men are walking on it. Following completion of an
area, approximately one quarter of the deck, the smooth surface base sheet
is torched on and up the wall about 12 inches and the roof is watertight. We
did find out that the rectangular box on the lower roof deck is a solid
reinforced concrete pad probably for future mechanical equipment and the
other smaller pads are for supplementary support of the penthouse sun decks
to keep those decks off the roof membrane.
West Coast and I met with Jim Mabry from Mabry Brothers Mechanical to
discuss the repairs to the electrical feeds through the slabs and the
lightweight. From what he observed, and he will have one of his electricians
come out Monday morning to confirm his belief, we may be able to abandon the
existing conduit and wiring in the slabs and run new flexible plastic
conduit from the wall-mounted disconnects and along the new support rails
for the condensing units. This would keep the mechanical decks cleaner and
minimize the number of penetrations in the roofing membranes.
One item West Coast did say regarding the new roof panels, that when the
seaming machine comes out to run the 180 degree double lap seam, due to the
overall thickness of the aluminum sheets and the clips, the finished look
along the seams will be a little wavy.
Finally, West Coast is providing daily clean-up of nails, fasteners and
screws that have fallen onto the grass areas and driveways. Early Friday
they came out and covered the pool with Styrofoam blocks, 2x4s, plywood and
plastic. It is definitely off-limits to everybody until their work is
completed. However, Tom has an area he can lift up to check the pool
chemistry and add chlorine.
