Progress update for the one's interested;

Attachment 13024 Floor finishes going down. 8000 sq. ft of 6"x6" quarry tile on a running bond.

Attachment 13025 Anti-fracture membrane installed over the 12'x12' slab control/expansion joints and a 24' x 24' control joint pattern on the tile.

Attachment 13026 Painting completed and up lighting installed.

Attachment 13027 Spiral staircase to second floor. Stairs will have granite treads and risers with a thermal finish slated to be installed next week.

Attachment 13028 The rush for completion is on.
Standing seam copper being installed on the barrel roof.

Meanwhile on the other side of the project of phase two;

Attachment 13029 Well, footings have been stripped and cleaned ready for wall layout for the formwork.

Attachment 13030

Attachment 13031 Pouring the elevator pit footer
A water stop has been cast in the base footer to make the pit water tight.

Attachment 13032 Two matts of steel at the elevator pit. A two foot sump hole incorporated in the pit for future sump pump that will be connected to an oil water separator on an alarm system.

Attachment 13033 Poured footings. Concrete mix design for the Project is 4000 PSI. 7-day break results should be in today. Anticipated 7 day break should be around 3800 to 4100 psi. Design is for 4000 psi at 28 days, but we use a mid-range water reducer additive that shoots up the compression strengths dramatically. Concrete is usually poured at between 4-5" slumps.

Well, in the past couple of weeks, the Book Store project has been delayed due to starting yet a third project on Campus of an emergency gym floor water problem.

After twenty years, water found it's way underneath the Field House Gym floor and destroyed it.

18,000 sq. ft. gym floor, to remove the floor, bleachers, and the concrete floor underneath.
Abandoned piping of all sorts over the years contributed to the water envasion.

So here are a couple of pictures of the form work in progress at the book store.

Attachment 13479

Attachment 13480 We do our own foundations and use the newest of the Western Alluminum form system. The gasketed system does not allow any liquids escape even with the use of the vibrator.

Do you think there is enough reinforcement?

Maybe House foundations would not bulge in with this design. ha. ha.

Hope some interested.

Will follow up on the 18,000 sq. ft. Gym Project.

What happens when water intrusion hits a Gym Floor,? everything has to be taken out and redone properly.

Here is a picture showing 18,000 sq. ft. of concrete floor being saw cut 6' x 6' to be taken out. Attachment 13550

Here is what a 6 mil. vapor barrier looks like at 20-25 years.

Attachment 13551

Nice clay soils to help the moisture.

Attachment 13552

Pretty interesting find.

Update on the Book Store Project.

Forms are done and the Concrete goes in. Hopefully the forms will hold.
With this Western Aluminum form system, it should not be a problem.

130 Cubic yards.

Attachment 13749Attachment 13751

Attachment 13750Attachment 13752
Attachment 13753

4000 PSI Concrete with Air Entrainment and mid-range additive for a water reducer for flow and pumpability ease.

Hope it interest some and will provide the next phase of water proofing, perimeter drainage and backfill.

Don't we all love this hard work? ha. ha.

I love it, I just delegate my authority now. ha. ha.

Well, kids are moving in on the 28th of this month, and right at the wire the Northern part of the project is pretty well complete. Phew that is to close for comfort.

Spiral staircase brings them up to the College Pub.
That should be fun to watch. ha. ha.

Hi Marcel, nice project! you must be glad it's winding down,

Remember my project in No. Berwick where I was converting a ranch into a cape? Well two months later we have the permit! funding is secured, just waiting for paper work from the bank.

Job includes a second story addition with a full dormer, complete trenching around the foundation for a perimeter drain, upgrading the electrical service to 200 amps and putting it underground from the house to the street.

OH, by the way, they actually use the 1999 BOCA code!!!! this should be interesting as most of Maine uses the 2003 IBC.

I'll post some picture's, sorry not commercial but interesting anyway.

[Marcel R. Cyr]

Peter, how did you manage to get the permit? Was it not turned down the first time?

Marcel

[Peter C. Russell]

I finally got the town manager to agree that since the house was built before the town had any zoning it should be exempt. He agreed.

I'll post pictures as we go.

[Marcel R. Cyr]

Wrapping up the Project before the 28th.

Attachment 13877Landscape improvements going in like this 2' thick granite block retaining wall. The back side of the wall backfilled with stone and a fabric to prevent silt from coming out the vertical and horizontal joints.


Attachment 13878 Installing black granite counter tops in the food court. Came in about 8-10' pieces and heavy as a rock, ha. ha.

Attachment 13879 Checking out the epoxy joint adhesive on the granit and figured I would also capture the gas hook-up to the grill.
The gas supply comes from underground and up to the ceiling of the second floor where the Main Gas shut off is as it comes in the building and also serves the roof top Make-up air unit for the exhaust hood.

It is kind of redundant, because the gas valve that you see behind the grill will activate when a head on the suppression system activates and also sends a signal to the fire alarm panel. The fire alarm panel will then activate the main gas shut-off where it comes in to the building.

The main gas shut off was Engineered with the type that closes when the fire alarm panel is energized.
When the fire alarm panel is reset, the gas valve was automatically open.

Well, I did not buy this set-up and brought it up to the Owners and Architect.

I said the way you have this designed, everytime you have a fire alarm drill or the real thing and re-set the alarm, the gas is now flowing in the building with the possibility of pilots out, defective thermal couples, defective electronic gas selenoids, and gas is pouring in.

They entertained my safety concern and paid an extra $1400 to change the main valve to a Mainually Reset Valve.

Notice in the picture the steel cable that will prevent the flexible gas line from being damaged when the grill is rolled out for cleaning purposes.

Attachment 13880 Fire suppression system electrical and fire alarm interface control box.

Attachment 13881 Fire suppression system at the Pizza Oven.
Hope they don't burn my pizza with an open flame. ha. ha.

Well, back to the Gym Project.

Things are going along fairly well considering it is 18,000 sq. ft..

The existing slab all removed and 6" of stone and underdrain grid has been installed.

The vapor barrier has been installed along with a re-bar matt at 16" o.c. spacing.

The reinforcement is because it will not be saw cut for control joints in prevention of slab curling, which would not work with the tolerance of the Gym Floor installation.

The Gym floor requirements on moisture is set at no more than 4.5 lbs. per 1000 s. f. of slab area in 24 hours.

Some flooring material requires 3 but no more than 5 for any finished flooring material.

Attachment 13896Attachment 13897Attachment 13898[ATTACH]

You will notice that the vapor barrier is down and Manufactured by Grace Manufacturing.
This product has a Perm rating of 0.00.
The critical fact of vapor permeability importance is due to the floor system being installed and it's requirement as of other floors to remain in a usefull state as it was designed for.

Attachment 13901

As you can see here in an inspection area, the underdrainage is visible in 6" of stone with a textile fabric on top of the clayier till.
This is a depression also for gym tennis court inserts.

Above and beyond this and extra measure, a complete perimeter installation of floor drains are being installed under the wood floor to guard from a water source other than the ground. These are connected to an outside outfall.

Since the use of this gym is critical, eliminating slab moisture is of the up most importance and procedures on this is explained in another post that I will insert in the BB., under this same category.

Vapor barriers: nuisance or necessity.

Hope some learn the importance of this information.

Yes and I have all seen the cement finishers when they think no one is looking to take their shovels and punch the Plastic so the floor will set up quicker so the do not have to work 1/2 the night finnishing the floor.

Hope they do not do this any more .

Roy; they would not even think of it when I am around, and the only water they are going to see is the bleed water.
We will be using a mid-range concrete with high cement low water ratio, so that should not be a problem.

And yes I have seen that stunt you are talking about.

Last time it happened, it cost them some bucks to come and clean the floor drain traps. ha. ha.

[Marcel R. Cyr]

I am in the hopes that I will have time to be present on Thursday's projected concrete pour scheduled for the 18,000 s. f. pour with the use of a laser screed so I can share the experience with all Members.

Will do what I can to keep you all in mind and post as many pics as I can for those that have not seen this type of installation.

Marcel

[Marcel R. Cyr]

Well, the gym floor pour is on schedule and ongoing, and expect to be done by 1:30 p.m..

The mix design ended up being a 4000 psi mix with 1&1/2" and 3/4" stone.
Midrange additive was also added with no air entrainment.

Super flat floor achieved using a laser screed machine with a tolerance of 1/8" in ten feet for the gym floor.

300 cubic yards is anticipated.
The re-bar mat is being lifted on to plastic chairs as the machine moves back.

Here are some pictures.
