stair install part 2

With the integral landing stair install complete, focus has now shifted to the parallam stair install.  These will have posts and landing fabricated on site, and will be more time consuming due to the custom nature of the work.  Fortunately the basement stairs were able to be installed and the landings will support the stairs to the second floor.

With the landing built, the heavy set of six rise stairs were slid into place from the main floor.  

This is the basement stair as shown from the top floor.  With these in place the final basement framing can take place

Ready for install!

Stair install part 1

The first set of stairs to be installed features integral landings.  This means the landing and the treads are connected and self supporting.  Once bolted to the wall, no further structural support is required.

these stairs are ready for safety railing to be installed

Stairs update

With the raw material prepped and sent back to the shop, it seemed like a good time to visit and check on the progress.  The open tread stairs were almost ready for delivery and assembly of the final pieces were underway.  The basement stairs were also nearing completion and have a very unique look to them.  More pics will be posted once the stairs are delivered and installed next week, and again when the landings are prepped and the staining is complete.  Eventually we plan to have a unique metal railing installed.

Heating, Ventilation and Air Conditioning (HVAC)

With the roof on we are able to install the HVAC system.  In Calgary it is key to have a very efficient furnace and ventilation system.  On this install we are using an upgraded furnace that features a variable speed fan and dual stage burner. Basically this allows the furnace to run at less than maximum speed and gas combustion, thus it is quieter and more efficient.  The furnace needs to operate through a huge range of outdoor temperature while keeping interior temperature within a small comfort zone, so it makes a lot of sense to have the variable speed unit installed.  We also can scavenge the stale air we have paid to heat by using an energy recovery system where the stale air has its heat partially transferred to the incoming cold exterior air.  This also prevents uncontrolled cold air from entering into the mechanical room and possibly causing a draft.  The installation team was extremely proficient and had most of the two heating systems installed over a two day period.  It is fortunate there are many good tradesmen in Calgary. This crew from WJ Mechanical had a combination of over 45 years of sheet metal bashing experience, and it showed!

Heat runs through the very few interior walls on the main floor

Having the tin bashers cooperate with the plumbing (already installed) can be a problem on a custom house as the routes are not always pre-determined collaboratively.  In this instance, it work out fine

Dropped ceiling here must be rebuilt and the plumbing vent is cut out

Windows

For the window installation, we are using a metal clad vinyl frame with a typical dual pane low e window.  These are quite effective in keeping the cold out and also some of the hot western sun out that will be bearing down on the front of the building.  Here is a photo of the window installation.

Fireplace preparation

We will be installing two fireplaces per home,  one in the living room and a second in the master bath.  The basement should not need a fireplace given that we are installing in-floor heating in the slab.  The  bathroom fireplace vents through the roof and the install crew will do that job, but the living room fireplace will vent through the wall, so insulation, poly and drywall are needed to be installed behind the unit.  Here is a picture of the rough framing for the fireplace.  We have some creative ideas of how to deal with the finishes of the living room fireplace that we are going to discuss later.

Ready for the fireplace installation

Roofing and skylights

With the rainy season fast approaching (and the multiple snowfalls and rain of late winter behind us) we were able to get the building shingled.  With the skylights on as well the building is significantly protected during rain and we can focus on the interior now up until we can apply for the pre-board inspection.  It is always a huge relief to get a house shingled in Calgary and of course it aids in keeping the birds out!

With shingles on and the 'whirly bird' installed we will ensure good roof cavity ventilation

The skylights are carefully flashed to ensure a watertight seal

Interior stairs

For the right side house, we decided to pursue a less conventional stair installation using an open tread concept but with a solid industrial style timber finish.  To do this we will use a parallam beam (3.5 inch width treads), with notched stringers placed at the 1/3 and 2/3 increment of the tread.  These will be heavily prepped by sanding the boards, and eventually stained and clear coated. Here are some initial images of the significant preparation underway to make these stairs a reality.

A hardwood floor sander is needed to remove a significant layer of material

All four sides of each board must be sanded

Safely loaded and the boards are on their way back to the shop for assembly
