About this file
This is a Distribution of Quantities Backup Calculations document prepared by Pare Corporation for the Rhode Island Department of Transportation (RIDOT) covering preservation repairs to two railroad bridges in Rhode Island under Contract No. 2026-CB-036. The project includes structural steel repairs, temporary shoring, painting of existing structural steel, and traffic control at the Pleasant View Railroad Bridge (056301) in Pawtucket and the Smithfield Avenue Railroad Bridge (093201) in Providence. For Bridge 056301, quantities include 4,650 pounds of structural steel repairs, 13 temporary shoring beams, 1,000 square feet of painting of existing structural steel, and a $10,000 force account bank for unexpected Amtrak downtime. For Bridge 093201, quantities total 3,390 pounds of structural steel repairs, 7 temporary shoring beams, 700 square feet of painting of existing structural steel, and a $10,000 force account bank for unexpected Amtrak downtime. Temporary traffic protection requirements vary by location: Bridge 056301 requires 108 traffic signs and 1,300 plastic pipe barricades for the I-95 highway location with 52 work days and 2 flagpersons; Bridge 093201 requires 99 traffic signs and 1,600 plastic pipe barricades for the Smithfield Avenue location with 32 work days and 2 flagpersons.
The detailed backup calculations show structural steel repair quantities derived from measured plate and bent plate dimensions with a 10% contingency added for dimensional variations and hardware. Unit weight of steel is calculated at 490 pounds per cubic foot. Painting quantities are calculated from girder perimeters and lengths, with a 15% increase to account for hardware and surface variation. The document was prepared with multiple estimators and reviewers, with final re-estimations completed on June 23-24, 2026. All work shall comply with the February 2026 Standard Specifications for Road & Bridge Construction (Blue Book). The two bridges are part of federal aid project numbers BHO-PRES(020) and 3RD-PRTY(374) under the RIDOT TO9 2025 General Bridge Repairs project C-1-RI 23124.03.
