Update on the project for Brian Wood of FMCBC grant committee.
Depending on receiving the grant from FMCBC, option #4 (long line) is currently the preferred option.
I spoke with Darren at Black Tusk Helicopters. Flight time from Squamish airport to Sigurd Creek is 10 minutes each way. Flight time to staging area on the Ashlu is 6 minutes each way.
Helicopter rates and loads- The A-Star five person chopper is $2,257/hour including HST. It has a lift capacity of 1,400 pounds.
- The Bell three person chopper is $1,260/hour inclusive of HST. It's lift is 600 pounds.
Regarding option #3 - wire ropeAesthetically, this is the least desirable. Interestingly, I spoke with Christian Veenstra of the VOC. I picked up a rock drill from him last night. The VOC put in a wire rope crossing last fall of the outlet of Long Lake leading to the Brian Waddington hut. They used 3/4 inch rock hangers. They sheared off this spring. It was a possibility no one foresaw. It looks like an ice dam must have formed against the cable snapping it. I am also concerned that we would have to anchor the wire across Sigurd Creek to trees. That could be damaging to the trees and also may not be sufficiently sturdy. We had a wire rope hand rail on the footbridge around 2001 but it did not last through the first winter. So, at this point I am not in favor of a wire rope crossing.
If we receive the FMCBC grant, our total grant monies will be $4500. This is how we propose to allocate it.
There will be two heli-assisted work parties over two separate weekends in August 2012. We are ready to go with the first work party on the August long weekend, once we receive confirmation of the grant monies.
First work partyPurpose of the first work party is to:
- Prepare the bridge abutments for the log
- Measure and cut the log stringer(s) for the crossing
- Time permitting, construct the shorter crossing from the south bank to the rock.
Fly in from Squamish in the Bell 3-person chopper. Three persons on the flight with the following tools:
- 20" Stihl chainsaw
- 16" Mac 10-10 chainsaw as backup
- fuel and oil
- Mikata rock drill
- rock anchors and hangers
- additional battery packs for rock drill
- nails and spikes to 12 inches
- 100 feet of 5/8" hemp rope for pulling logs for abutments
- wire rope for anchoring bridge abutments (length and diameter TBD)
- wire rope cable clamps
- wire rope cable cutter
- sledge hammer
- buckets for carrying rip rap material
- wet suit or hip waders for crossing Sigurd Creek
- come-a-long
- jack
- pry bar(s)
- bent shovels
- shovels
- mattocks
- approx. forty 2- to 3-foot long rebar drifts
- hand drill and bits for rebar
- axe
- hand saws
- loppers
- long measuring tape
- hi-viz vests
- first aid kit including bone splints
- two-way radios
Publish the trip on the BCMC schedule to get additional volunteers. Volunteers can walk in from Ashlu Main or arrange individual flights from Ashlu staging area, flight cost to be borne by individuals.
Second work partyPurpose of the second work party is to:
- Long line the prepared log stringer(s) into place
- Anchor the log to abutment
Fly in from Squamish in the A-Star 5-person chopper. Five persons on the flight with the following tools:
- 20" Stihl chainsaw
- fuel and oil
- chicken wire to surface the log
- Adze to level the log
The A-Star will take out all tools from the first work party that are no longer required.
