The staff of Stahl Sheaffer has designed hundreds of bridges, ranging from 8 feet to over
3,000 feet in length. For projects with townships, counties, and boroughs the funding
mechanisms have included Liquid Fuels Funds, General Funds, Retroactive
Reimbursements, and both Federal and State Funding Participation.
Stahl Sheaffer also has staff with extensive experience in completing bridge, tunnel, and
sign structure safety inspections in accordance with the National Bridge Safety Inspection
(NBIS) program and the National Tunnel Inspection Standards (NTIS). Our CBSI- and NCTI-
certified staff members have completed routine, in-depth, and emergency (flood or
accident) inspections, load rating analysis, and emergency repair recommendations for
bridges and tunnels of various constructions, spans, and lengths. Project examples follow.
Stahl Sheaffer as the prime consultant, completed Agreement E01385 SR 2006, Section
A01 over Unnamed Tributary to Cedar Run Bridge Replacement, Centre County in 2010.
The project involved the construction of a box culvert and stream relocation to replace a
load posted structure and improve hydraulic performance in this flood prone area. To
arrive at the preferred alternative, Stahl Sheaffer evaluated all options and chose the one
that provides the greatest number of benefits, including: meeting the majority of design
criteria, improving safety, minimizing right-of-way and utility impacts, removing hydraulic
obstructions, improving flooding elevations, minimizing disruptions to residential property
access during construction, and improving fish passage.
On this project, Stahl Sheaffer managed and/or performed all aspects of the
Transportation Development Process, including: Archaeology, Historic Resources, Stream
Relocation, Public Involvement, Utility Coordination and Relocation, Alternative Studies,
4(f) Resources, Agricultural Resources, 2-D Hydraulic Analysis, and Traffic Calming
Measures. Stahl Sheaffer facilitated ten well attended, highly publicized public meetings
and obtained public input in the development of alternatives
“Stahl Sheaffer excelled on the
completion of Part 2 of this agreement,
accelerating the controversial project
resulting in letting the project nearly one
year ahead of the originally scheduled
let date. Stahl Sheaffer performed very
well at facilitating the public workshops
meeting the needs of the Department as
well as other project stakeholders. Stahl
Sheaffer was very responsive to the
project's needs, often times meeting with
residents or design team members on
very short notice. Jeff Sheaffer and
Aaron Fayish performed very well at
both the technical end of the design and
facilitating the public's needs into the
project. It was a pleasure working with
Stahl Sheaffer on this project.”

Stahl Sheaffer completed the design of two structures on the ATV trail in Sproul State Park
near Monument, PA. The first structure consisted of a 20’ x 5’ precast reinforced concrete
box culvert with precast end sections.
The second structure required the foundation design for a 150’ long prefabricated steel truss
bridge. Design of the truss foundation and accurate layout of the final bridge span/location
were imperative due to potential conflicts with the existing railroad bridge abutments that
were to remain in place. Due to the location of these abutments, the proposed span was
lengthened to locate the new abutments and footings behind both existing
abutments. These bridges were constructed in 2011.

Stahl Sheaffer completed the design and initial inspection in 2009 of the 42' long precast
reinforced concrete arch structure carrying Linnippi Trail over McElhatten Run in Wayne
Township, Clinton County, near Lock Haven, PA. This structure was designed by Stahl
Sheaffer and is the only means of access to the Linnippi Trail Housing Development and
the Lock Haven Area Water Authority. The two-lane structure is adjacent to companion
structures carrying SR 220 over McElhatten Run. The structure featured guiderail mounted
to the arch spandrel walls and significant amounts of rip-rap to maintain the stream
alignment, reduce scour effects on the structure, and maintain the normal stream width
that supports native trout reproduction.
Stahl Sheaffer performed coordination with PennDOT Engineering District 2-0 to assign
structure numbers to the newly constructed facility that was ultimately turned over to the
Wayne Township Supervisors after the housing development owner completed the bridge
construction. Stahl Sheaffer provided sufficient copies of the reports for owner records,
Township records and submission to PennDOT Engineering District 2-0 for approval and
record keeping purposes.

Stahl Sheaffer provided engineering services for the replacement of a single-span cast-in-
place reinforced concrete arch carrying Arrowhead Trail over SR 1004, Sugar Camp Road.
Three structure alternatives were investigated during preliminary design. The options
included a precast reinforced concrete arch under fill, a single-span composite prestressed
concrete I-beam bridge on pile supported integral abutments, and a single-span
prestressed concrete adjacent box beam bridge on cantilever abutments. The selected
replacement is a 145'-6" single span structure consisting of three 33/71.5 PA Bulb-Tee
Beams on integral abutments. To complete the design process, coordination was required
with PennDOT District 12-0 to obtain Structural Adequacy and Foundation Approval.
The three structure alternatives considered included: Alternate No. 1, a precast reinforced
concrete arch; Alternate No. 2, a single-span composite prestressed concrete I-beam
bridge with a reinforced concrete deck on integral abutments; and Alternate No. 3, a
single-span composite prestressed concrete adjacent box beam bridge with a reinforced
concrete deck. The three alternatives were evaluated to determine the most appropriate
replacement structure.
Upon evaluation of the criteria, Stahl Sheaffer
concluded that Alternate No. 2 was the most
feasible alternative. This alternate selection was
significantly less expensive than Alternate No. 1 and
Alternate No. 3. Additionally, this structure type
easily accommodated SR 1004 if the horizontal
alignment is improved to eliminate the S-curve
within the existing structure. Therefore, Stahl
Sheaffer recommended replacing the existing
structure with Alternate No. 2, a single-span
composite prestressed concrete I-beam bridge on
integral abutments using two 33/85.5 PA Bulb-Tee
beams spaced at 8’-8 ¼” o.c. with an 8.0” reinforced
concrete deck and a 14’-0” curb-to-curb.
The horizontal and vertical geometry of SR 1004 was
based on a 35-mph design speed. There is an
approximate grade separation of 37 feet between
Arrowhead Trail and SR 1004. With a minimum
under clearance of 16’-6”, there is trivial effect on
vertical profile based on the existing geometry
constraints. The trail and SR 1004 will be replaced on similar vertical profiles.

Using advanced materials, Stahl Sheaffer strengthened PennDOT’s bridge on SR 3016 in
Greene County while keeping the trucks running for our client. Fiber Reinforced Polymer
(FRP) technology installed at the bridge’s beam ends strengthened the existing concrete by
adding shear capacity for the client’s special load conditions.
In early 2016 Stahl Sheaffer was asked to assess construction routes for planned or
developing well sites in Aleppo Township. One route involved a concrete T-beam bridge
over the South Fork of Wheeling Creek. Initial ratings of the existing bridge showed it could
support legal truck traffic but was not capable of carrying the shear loading from the
client’s heaviest special hauling vehicles, with the interior beams found to be below
capacity. Several alternatives were originally considered, including the construction of
corbels to extend the beam seats, strengthening from above using a strong-back beam
system, individual beam strengthening using a polymer/fiber wrap, and superstructure
replacement. Each option was assessed for drawbacks such as constricting the hydraulic
opening, creating roadside obstacles, or excessive cost. Once fully evaluated, the Fiber
Reinforced Polymer (FRP) retrofit was determined to be the most advantageous, especially
considering it was significantly less expensive than the lowest replacement estimate,
coming in at $107,500 including design, permits, traffic control, and the complete cost of
installation (which is approximately 60% less than a new concrete beam superstructure).
To advance the FRP method, Stahl Sheaffer expanded collaboration on the project by
bringing on design-builder Pullman/Structural Technologies, out of Carnegie. Teaming with
Pullman, Stahl Sheaffer was able to develop a set of design plans that met PennDOT’s
approval. Design calculations followed AASHTO’s 2012 Guide Specifications for Design of
Bonded FRP Systems for Repair. U-wrap FRP strengthening was designed to increase the
shear capacity of the existing girders by 35 kips using V-wrap C200 unidirectional carbon
sheets and V-wrap 700 epoxy adhesive. At the intersection between
girders and diaphragms, strengthening was achieved by using an L-
wrap configuration.
Pullman supplied all material, safety, installation, and quality
documentation leading up to the construction phase in October of
2016. Their crew worked for six days, completing the installation in
under a week. Access was gained by temporary scaffolding bolted to
the abutment walls. Following AASHTO and Pullman’s quality plan,
pull-off tests were performed in the field to ensure adhesion, and
witness panels were tested in the lab to ensure resin saturation had
taken place and environmental conditions were conducive to proper
curing. Stahl Sheaffer and PennDOT supplied full-time inspection on
the job.

This project consisted of the rehabilitation of an existing bridge carrying SR 4002 over
North Fork Beech Creek in Snow Shoe Township, Centre County. This project included
replacing the existing bridge superstructure/deck with new steel I-beams and an open grid
steel deck. As part of the rehabilitation, the existing bridge railing was replaced with a
structure mounted guide rail system. The existing abutments were reused and the
proposed low chord and roadway elevations matched existing conditions. The total
superstructure depth was designed to match the existing superstructure depth including
bearings, beams, deck, and pavement.
