.1 Preparing skateboard units for removal.

.3 Relocating armourstone blocks.
.4 Transporting skateboard units to Storage Location
.5 Unloading skateboard units and preparing for storage, including placing

.6 Cleaning up both work sites.
Scheduling of Work
.1
Plan safe and efficient processes for all removal and storage work steps in
consultation with Barkman Concrete Ltd., other subcontractors and City’s
representative as soon as possible after contract award. Note: Barkman Concrete
Ltd. tasks and responsibilities are fully outlined in their quotation provided with
Tender. Review detailed steps and work areas on site with City’s representative
at mandatory pre-start site meeting. Many of the lifting eyes are accessible
without moving the units, so grout removal can begin prior to crane operator start.
However as many of these lifting eyes are on riding surfaces, grout removal
should start close to the lift day to minimize chance of injury in case
skateboarders gain access to the work area.
.2
Schedule all removal and storage steps with subcontractors to ensure a smooth
and efficient process on site, and meet the City’s requirement to remove the
equipment off site as soon as possible; preferably while frost is still present in the
ground to minimize site damage and public site use is low. The later the work
timing, the greater the interest in public use of the skateboard items and
possibility of work delays.
.3
Note that there will be one (1) Barkman Concrete Ltd. Representative, and
in order to preserve the skateboard unit warrantee he or she MUST oversee
