Subject Park Road 22 Bridge(Project No.6281)-Contract Amendment No.2
Dear Mr. Biles:
We are proposing Amendment No. 2 to our contract to address additional work required to
investigate and redesign the two arch bridge concept into a three arch concept to mitigate for
poor soil conditions encountered at the bridge location.
The design team had proceeded with the final design phase of the bridge to approximately
the 60% point when foundation and retaining wall designs were far enough along to perform an
accurate global stability analysis.When this was done,the geotechnical engineer determined that
the height of backfill relative to the location of the bulkhead placed excessive lateral loads on the
bulkhead that would require a design that was well in excess of what was anticipated. In addition
the weight of the backfin could cause up to 6' of subsidence and consolidation in the areas
leading up to the arches.
The design team investigated multiple options to mitigate these effects including geo-foam
backfill, light weight aggregate backfill and cement slurry stabilization. All of these caused large
price increases or were ruled out as unacceptable alternatives by TXDOT.
The design alternative chosen was to use a three arch concept instead of a two arch
concept. Using three arches allowed the bridge to be lowered about 2'.This is because the height
of the bridge was being driven by the clearance for pedestrians and carts, not boat clearance
over the water. Pedestrian clearances can now be measured to the middle of the arch instead of
at the leg. This design also pushed the lateral loads from the backfill further back from the
bulkhead allowing for a typical bulkhead design. The lower bridge height also reduced the
potential subsidence and consolidation.
The additional effort required to work through this design change process and other
additional items included:
• Alternatives analysis with the geotechnical and structural engineers
• Redesign of the vertical curve and effected areas,particularly drainage
• Structural design revisions to the arch bridge design, foundations and the retaining
walls
• Update of the Categorical Exclusion(CE)document
• Addition of turning lanes at Nemo Crt and Azore's Drift Dr, to accommodate
increased movements due to adjacent development
• Reduce Construction Observation Services

additional information.
