Sep 5 2017 Kees and Claire Hut Construction Report

Another two weeks have passed and we are now walking around a building! Well… atleast we’re walking around the basement. The concrete pour for the foundation walls happened on August 30th. With the larger Bell 212 off fire fighting up the Mamquam River, it took two Astars from Blackcomb Helicopters and a tiring 10 hours to get it done. Trucks from Cardinal Concrete staged out of the base of the Harmony chair on Whistler once again. We have to thank Tasso Lazaridis, Kat Siepmann and Michael Blaxland for managing the concrete buckets there. Plus the team from Coast Essential Construction: Trevor MacDonald, Reid Madiuk, JD Hare, Troy Jungen and Kelven Vail and volunteers: Rob Withey, Tom Vernon, and Rodger Williams for pouring the walls on site.

The forms were stripped soon after, revealing the clean insulated foundation walls and concrete piers and columns. Over the Labour Day weekend, the waterproof membrane was applied to the exterior and top of the walls, followed by the black drain mat. The membrane will protect the hut from water infiltration and the mat helps to direct water away from the walls and into the perimeter footing draintile.

Henry Van Hell of Envirosept came in to start work on the greywater dispersion system. A 2 foot trench was dug by excavator operator Alex McCullough of North Construction for the main discharge line from the hut to the pump chamber below. The chamber was buried at the low point of the field and anchored to heavy boulders. Henry also installed the dose meter and the air release valve with help from Stephen McVeigh. Volunteers began the task of trenching the driplines… eight at 63 meters long each to be dug by hand. While only 4” wide and 6” deep, it was surprisingly hard going with a lot of rock.

With cooler late summer weather, many volunteers are hiking in over the Musical Bumps from Whistler Mountain to help out at camp. The cooks, Kim Eijdenberg, Marlene Ford and Bridget Daley, continue to keep people happy with boxes of food flying in every 3 to 5 days.

A big push is on now to finish the work for the season and demobilize. The next tasks are the completion of the perimeter draintile and the installation of one floor drain. We have one more concrete pour to do for a slab on grade. Then we’ll be completing the greywater dispersion system, building rock retaining walls and backfilling soil. It will be very rewarding to see the site re-graded and close to its final form.

We’re on the home stretch, but we still need volunteers to get us to the end. If you’re back from your summer holidays, please consider coming out now! See the volunteer schedule for the last shifts in September:

Black drain mat will direct water away from the walls and into the perimeter draintile. Half of this surface will be below grade once the backfill is complete; the rest will be clad.
Bas Rijniersce and John Duffy apply the drain mat to the west wall of the hut. When complete the concrete piers will support posts for the entry deck above.
Work starts on the greywater dispersion system. A trench is dug and the discharge line and electrical conduit is installed from the hut to the pump chamber below.
Manrico Scremin and Lawrence MacIntosh begin the driplines with mattock and shovel. Excess rock will be carried to nearby talus fields, and in time the meadow will knit back together.
Heading back to camp and dinner at the end of the day. Snow helps to wash off the dust.
