The Big Bunker Theory

No doubt some of you have heard of the Diefenbunker. Most everyone who has visited Turtle Falls while the rebar was being installed wondered if we were building the next Diefenbunker. Oh wait...that would mean it might be named the Harperbunker. Hell no...no way!! I'll admit there is a lot of steel in this house and I suppose if you use your imagination you may see some similarities in the following photos.

(Sorry PM Harper, you cannot have your name on this bunker!)
21,000 linear feet of rebar in the slab and walls equals about 10 tons.
The Diefenbunker has 5000 tons of steel. Not even close!
Forming the TurtleBunker walls.
 
So why so much steel, you ask? The concrete slab is a full 12 inches (30.5cm) thick sitting on a 14 inch (35.5cm) floating bed of Styrofoam. Concrete not only shrinks as it dries but continues to expand and contract with temperature changes. The rebar reduces the amount of cracking the slab will endure over its lifetime and helps distribute the weight of loadbearing walls. No saw-cut contraction joints were allowed to be cut in this slab, as specified by the engineers, probably because these saw cuts would likely have to be about 3 inches (7.6cm) deep and would therefore cut through the top layer of rebar installed just 2 inches (5cm) from the slab's surface.

The walls required a similar seemingly over-abundance of rebar. The back wall of the house will be a retaining wall for the hill behind it. Since the concrete is only 6 inches (15.2cm) thick, standing 10 feet (3m) tall, the steel needed to be plentiful and steadfast. There will be massive amounts of pressure against that back wall once backfilled. And even though every last person who has seen the rebar for this house has shaken their heads or rolled their eyes in disbelief and asked us if we are building a skyscraper...or the next Diefenbunker...or if we've just lost our minds all together, we simply smile inside and feel a great sense of security knowing this house has been engineered to last. Nuclear attack, earthquakes and hurricanes be damned. Why should governmental figures be the only ones allowed to hunker down in a bunker when the outside world gets a little out of control?

We have so many names for this house: Casa Tortuga, The Turtle Palace, TurtleBunker. But maybe it really needs to be named Castle Tortuga. At one moment during the removal of forms from the walls the whole scene reminded us of a castle. Yes? All we need now is a moat and a drawbridge.

Castle Tortuga in the making?
A stressful, yet successful pour complete.

Notice all the little nibs left behind from the form ties both inside and out in the above photo. Since we will be installing a rigid insulation on both the inside and outside of the concrete, each and every one of those nibs needed to be knocked off. Fun times at Turtle Falls consisted of nib-knocking for days...and days!

The last nib gets knocked.

I just wouldn't be a good Canadian if I didn't mention the weather. This summer has looked like the following picture every other day. We got one lonely week of solid sunshine somewhere between the first and second weeks of August. Ever since, we've been back to rain almost every other day.

This is the very tiresome scene we see too much of from Priscilla's window.

The ironic part about waterproofing is that things need to be dry to apply waterproofing materials. As you may have guessed from my weather report there was quite a waiting period before we could get to the waterproofing of the joint at the floor and wall. Once we did get our sunny week we wasted no time. The first step was an elastomeric caulk right in the joint. This product needed a week to cure before we could roll on the rubberized membrane. Mother Nature played nice that week and gave us just enough dry days to get this very important step done. Passive houses need to be very air tight and this sealing detail had to be done before we can proceed with anything else.

Those of you familiar with sealing joints for passive house may wonder why we opted not to use the more convenient tapes for this step. It turns out we have a few uneven sections in our floor where the water collects up against this joint and the tapes would most likely fail after successive water submersions thanks to all the rain we've been getting. Even once we get rolling with the framing it will be a while before the roof is installed and any rainwater would be impossible to remove from those collection areas once the 2x6 stud wall is in place. So we chose to caulk and roll! {groan}

Floor/wall joint is sealed with elastomeric caulk for water and air-tightness.
Tooling the caulk for better coverage and adhesion.

waterproofing membrane.

Not all has been lost due to weather though. We have kept the crew busy with building the Turtle Falls workshop while we got the TurtleBunker prepped for them. Here's what they've been up to while we've been nib-knocking and waterproof caulking...

The Turtle Falls workshop is looking mighty fine. Nice work guys!

That's all for now. Pray for sunshine!

Turtle's pace

You are probably wondering what is going on here at Turtle Falls. It's the first day of summer already and the progress with the building is moving along at a turtle's pace...thanks to the weather!

Yes, the weather is the gift that just keeps on giving. In the fall, the snow fell fast and furiously enough to halt our construction plans by mid-December. Now, incessant rain is messing with building schedules...big time...all over the county. The wet spring has delayed all construction around this area.

One would think we are building a swimming pool rather than a house. Check out the short video of trying to keep the water out of the foundation form so when the rebar guys do finally show up they don't have to install it wearing hip waders.



It's hard not to take it personally when the trades won't show for more than a day or two before they disappear again for several. I know they are behind the eight ball trying to keep all their other clients happy as well but it still makes us want to shackle them to the rebar (is that a bad thing?) and not set them free until something...anything...has been completed. By the way, has anyone seen the sun? It's pretty much a figment of our imaginations here at Turtle Falls.

As a side note, when the sun does make a rare appearance the roads become turtle obstacle courses. I guess they get tired of all the rain too and head to higher ground, away from flooded shorelines, to enjoy a brief moment of warmth and look for a cosy(?) spot for their future hatchlings. Can anyone tell me where turtles laid their eggs before roads were built? I can't believe the distances these creatures will travel to park their abounding back ends into the gravelly shoulders of roadways countywide.

The following picture is of Ras doing her bit for the environment by moving a substantially-sized snapping turtle off the middle of the road. The turtle was not impressed with her good Samaritan ways and did its best hissing and clawing imitation to scare the living daylights out of Ras...to the point that you may notice that, yet again, a turtle is falling! Rest assured Turtle was not hurt in the making of this heroic effort. Ras nearly had a heart attack...but Turtle was unharmed. After Ras finally got Turtle safely into the ditch, who's to know if she didn't just turn herself around and trundle back to her tarmacked sunning spot.
  
Ras: "You'll be much safer over here."
Turtle: "Get your hands off me, human!" 

Enough about the turtles. On to the building. I was hoping to have much more to report by now...but I don't. So here's where we're at while we wait for the trades people to wade through their rain-soaked backlogs...
   
Installing vapour barrier over 14"(35cm) of Styrofoam insulation.
All seams and plumbing protrusions need to be taped for a watertight seal.
Rain would have filled this form like a swimming pool so
we tucked the vapour barrier under the form to allow water to run out.
Installing rebar...in the rain!
Un-installing the rain...again! The shovel method doesn't work with the rebar.
Forming the notch around the perimeter of the slab required drilling holes
every 5"(13cm) in 2x6 lumber to accommodate the right angle dowels.
By the way, about 420 right angle dowels were bent on site.
Ras did a few dozen. Go girl!
The form as it sits today...almost ready for concrete. A bit more forming
work is necessary. More bracing is required as well.

And now we wait our turn for the crew to return to us. Promises have been made and broken for return dates. We are doing our best to remain patient. It is what it is...

"I ain't coming out 'til the rain stops."

Anticipation...

Well...here we are in the last week of April and the anticipation of starting construction again at Turtle Falls is growing, by leaps and bounds, with each passing day. It was a long, cold, and very snowy winter and it seems like eons ago that we made the decision to halt construction until spring. There are still a few delays we must wait out before construction can begin again. Nothing says it better than a picture...or several.

You might think the most obvious of the delays would be the high water. All roads leading to Turtle Falls are under water.
This guy stopped and asked us if it was safe to go through. I said 'yes,
as long as you go slow'. From the size of the spray,
 you can tell he was not interested in the advisement of caution.

The other watery road leading to Turtle Falls.

The load restrictions are the main reason for not starting right away. These restrictions are usually lifted by around the 1st of May. And with the amount of concrete we need for the slab and foundation it seems prudent to wait until fully loaded cement trucks are once again allowed to traverse the waterways...I mean...roadways.

Half loads in effect.

There is one delay that we have thwarted though. Our passive house windows and doors are in our possession! Well...they're in the possession of the window dealer at the moment. They have graciously agreed to store our order in their warehouse until they are needed on site. This is all very good news as I remember the 3-month delay we had to endure for doors for the last building project we did.

We are seriously impressed with the people from which we purchased our Gaulhofer windows and doors. The product is not only amazing but Herrmann's Timber-Frame Homes, from Curran Ontario, makes the whole scary process of ordering windows from a foreign country akin to ordering your daily double-double from Timmy's. Easy peasy! They will also be installing the product when we have progressed to that point. {sigh of relief!}  One less thing contractor Mark has to worry about.

Windows arrive safely from Austria during one of the coldest weeks in January.

These next photos have nothing to do with any construction delays. Just interesting...how high the water is in the lake at the moment.

The amount of flotsam, jetsam and zebra mussels on top of the deck tell us
the deck was 'under' water for some time.

The debris removal crew is hard at work.
The conservation authority made us build this deck above the high water line.
That high water line used to be about 4 feet (1.22m) lower than it is here. 
This picture is from last fall. Note the water level. If we had attached the
floating dock with the water as high as it is in the previous photo,
 we would have to walk 'up' the ramp to get to the boat.

We had every intention to get the dock in place during the Easter weekend but there was no way the boat was going in the lake as the ice was still pretty solid at either of the boat ramps we can use. So much for an early dock season! We'll try again next weekend. That will be the same weekend we attempt to de-mouse poor Priscilla...ugh! What is it with the love affair mice have with RV's?

That's all I've got for now.

Famous last words

Here's to hoping there are no more 4 month delays!

That was the last line I wrote in my previous post. Famous last words!

One should never think or write such ridiculous words at the end of November in this part of the country. What was I thinking? Mother Nature has a way of getting the last word in...always. Here's what the building site looks like now...

Whiteness as far as the eye can see!

...and it's snowing again as I write this!

The foot-deep blanket of snow looks lovely and I'm sure when the house is finally built I won't be so disappointed by its presence. Really, it is a gorgeous wintry scene here at Turtle Falls and that's all it will be now until spring...or at least a time when temperatures are conducive to pouring concrete. Along with the snow came the frigid temperatures, so we decided to close the site down until the thermometer and the concrete can play nicely together again.

So...until there is something else to report, and who knows when that will be, here are some fun photos, from prior to the snow, of the plumber making tracks in the foam for the plumbing bits that need to be below the concrete.

Cutting trenches in the foam with the trusty chainsaw.
Clearing trenches with the trusty hammer.
Setting the pipes with expanding foam.

Maybe I shouldn't push my luck with the hoping, but here's hoping you all have a wonderful time with family and friends during this Christmas holiday.

More later...much, much later,
Mimi

Let the building begin!

I can't believe it was the 2nd week of July when I last posted. A lot of life has happened since then, but not a lot of building. Until now!

We were hoping to be well into the project by this point, with not-so-distant visions of enjoying Turtle Falls in something other than a mobile mouse house. Poor Priscilla! She was neglected so much this summer that the vermin vacationed there more than we did. Why such neglectful behaviour towards our beloved Priscilla, you ask? The Reader's Digest version goes something like this....


Ras with her new, but gently-used, water toy.
On the very same day we were madly in the midst of buying a boat by text message...yes, we really bought a boat using only our opposable digits...a call came in from the hospital in the city to inform us that Ras's dad had taken a bad fall while out-and-about. The bad news...broken hip. They forgot to mention the unicorn horn growing on his forehead, the first point of impact during his fall. Fast forward to the partial hip replacement surgery, then a second surgery 5 days later, as a complication of the first surgery...oh, and did I mention Ras's dad, Lou, is 88. Anyway, he healed up pretty fast during his 2 months in the hospital and is now doing very well in his new long-term-care digs out near Turtle Falls. Needless to say, it was a hectic time (3 months in all) of hospital visits, organising 24-hour home care after the hospital stay, visiting and choosing long term care facilities, packing and moving Lou to his new place and clearing out his previous apartment. And hence, the reason Priscilla was left to fend for herself against the menacing mob of mice for the majority of the summer.

But why the delay in the building, you ask?

Let's just say that we lost the race against time to have Contractor Mark start our house before he had to start the next house in his queue. It all worked out as it should have though. The delayed start date for us gave us the chance to help Lou through his recovery and get him established in his new location. Lou loves his new joint...ha...I meant his new place, but I'm sure he probably loves his new and improved hip joint too!

Onward and upward...passive house Casa Tortuga is finally underway! It all started with one little truck loaded with high density geofoam for the sub-slab insulation. Then 2 more truck loads followed the next day. Smaller trucks are the only option for the winding driveway into Turtle Falls.

Here's what the excitement of the last few days looks like.

The first load of foam arrives at 4pm on Thursday.
Two more loads arrive mid-afternoon on Friday. And then we had a
weekend of high winds that lasted through to Monday night.
Nicer weather and the crew both arrive Tuesday, bright and early.
A chainsaw...with a foam-cutting blade?
Two layers of 7-inch (17.8cm) thick sheets getting assembled.
Seams are off-set to lessen thermal bridging.
14 inches (35.6cm) of high density, foot-warming, thermal-breaking
insulation for under the concrete slab.
Foam install almost complete.
The frost has no chance of getting into the ground now.
Next up is the plumber, so until he gets here the foam has been
covered with tarps to keep the wind and weather away.

Next up...the plumber will carve out the necessary water/waste lines in the foam before the slab gets poured.

Here's to hoping there are no more 4 month delays!

More later,
Mimi
