PACIFIC RAILWAY, PRINCE RUPERT, BRITISH COLUMBIA. 217 
PIER AND PLATFORM WORK. 
The first work to be undertaken will be the pier, marked “Pier No. 1”’ on 
the general plan. This will be 420 feet in length and 60 feet in width, the 
piling being on 10 x 5-foot centers. The pier will require about 600 piles. 
At the same time, there will be built the platform at the shore end of 
this pier 80 feet wide by 930 feet long, having an area of 74,400 square feet, 
and will require about 1,600 piles on 5 x 10-foot centers. 
At the western end of this platform there will be an extension off shore 
350 feet long by about 100 feet wide, and at right angles to this an extension 
560 feet long by 80 feet wide for the attachment of the floating dry-dock. 
It will be noticed that a double line of diagonal bracing is used in the pile 
work. This is on account of the excessive rise and fall of tide at Prince 
Rupert, which for spring tide is 25 feet. The tops of the piles are thoroughly 
secured by double 6 x 12-inch clamps and connected by 12 x 12-inch caps. 
The decking is to be of 4x 12-inch planking. Pilesare tobe creosoted. The 
total area of the platform and pier work will be 181,400 square feet. The 
completion of this work, it is expected, will provide ample space for the 
landing and handling of materials for the rest of the plant. 
LAUNCHING PLATFORM. 
In front of the main platform, east of the pier, there will be built a 
launching platform for side launching. This will be 80 feet wide by 440 feet 
long and will be carried on 16-inch piles on 5 x 10-foot centers, braced and 
reinforced by heavy piling along the edge over which the launching will 
take place. The general arrangement and bracing of this piling can be 
seen by referring to Plate 108, showing the platform in connection with the 
building shed. It will be noticed that the outer half of the building plat- 
form has a slope of one and three-fourth inches to the foot, which is approxi- 
mately the launching grade for side launching. 
POWER-HOUSE. 
The general location of the power-house will be seen by referring to 
Platero7. ‘The interior arrangement and equipment can be seen by reference 
to Plate 109. Electric power is to be furnished for operating the pumping 
machinery of the floating dry-dock, for compressing air and to operate 
machinery in the various pHOns: also, for furnishing electric lighting for the 
plant.
