Fisher Associates provided construction engineering services for the steel erection sub-contractor for the Phase 2 bridges
of the new Route 15 in Lindley, NY. Steel girder erection plan submittals were provided for three large, single and multi-span steel bridges that were erected
using 150 ton and a 275 ton cranes.
The submittals provided the sequence of girder erection, confirmed girder weights, designed temporary shoring towers, determined crane locations based on crane capacities and radii, and verified
the effect of the cranes on bridge substructures.
This project involved rehabilitation of
the powerhouse and pier foundations
of the Mount Morris Dam, located on
the Genesee River. Fisher Associates designed temporary shoring of a reinforced concrete slab spanning over
a spillway between an abutment of the dam and the powerhouse foundation.
The shoring provided a safe working surface for a 50 ton crane in a constrained site with limited access and resulted in no damage to the concrete slab.
As part of the Eastside Water Supply Project, Fisher was sub-contracted to design the rigging and work platforms needed to support the concrete slip forms used for construction of a 2.5 ft. thick reinforced concrete lining for raw intake tunnel riser shafts. The riser consisted of two risers; one was 45 ft. in diameter and 165 ft. in depth and the other was 20 ft. in diameter and 60 ft. tall, located inside the larger riser.
Fisher Associates was retained to provide construction engineering services for the Rehabilitation of the Fairport Road (Route 31F) Bridge over Irondequoit Creek in the Town of Perinton, NY. Fisher developed erection plans for the new pre-fabricated steel girder with concrete slab super-structure (Inverset) units, designed a temporary sheet pile wall to support vehicular traffic during staged construction and developed and designed a temporary pedestrian bridge to provide safe passage around the project site.
