Project Challenge:
The Federal Transit Administration mandates that the Southeastern
Pennsylvania Transportation Authority (SEPTA) inspect its bridges,
viaducts and culverts at least once every two years. SEPTA typically
performs most of these inspections with inhouse staff. However,
since the bridge inspection and reporting
program for the bridges on the Routes 100, 101 and 102 lines
needed to be completed within a three-month time frame, SEPTA
turned to K&H, who has assisted SEPTA on previous biennial
bridge inspections, to supplement its own forces and ensure
that the work would be completed by the required deadline.
Project Solution:
Under a General Engineering Contract Task Order Assignment,
K&H provided a Team Leader certified through PennDOT's comprehensive
Bridge Inspection Training Program and SEPTA's safety certification
program to perform visual biennial inspections of 84 railroad,
highway, bus, pedestrian and utility bridges located along SEPTA's
Route 100, 101 and 102 rail lines. The work included 63 bridges
along the Route 100 Line, 15 bridges along the Route 101 Line,
and 6 bridges along the Route 102 Line.
The majority of the bridges were constructed in the early 1900's.
Bridge types included single and multi-span systems comprised
of riveted steel deck and through girders, concrete arches and
culverts and a few newer precast concrete deck girder structures.
Scour and erosion were of particular concern at 28 of the bridge
structures that cross creeks and steams. The submerged potions
of abutments, piers and footings were probed to determine their
condition.
K&H's work included preparation of an inspection program
and schedule; a detailed visual inspection of each structure,
including exposed foundation elements; preparation of a photographic
record of existing conditions; updating of SEPTA's bridge inspection
database; and preparation of required bridge inspection
reports.
