1. STATEMENT OF QUALIFICATIONS d. Understanding of Need of major structural elements, retrofit repairs to fatigue prone details of steel girders, spot painting of structural steel elements, rehabilitation/new installation of deck drainage elements, replacement and upgrade of deteriorated bridge railing, embankment erosion control and the repair of existing scour countermeasures related to protecting the structural integrity of the bridge and install new approach slab or rehabilitation/ replacement of the existing one, alkali -silica -reactive aggregate mitigation, corrosion management systems, and fracture critical element replacement/rehabilitation. Task #4: Pronose Repair Work TTG will provide recommendations for the type of maintenance counter measures and minor repairs of the existing bridge as per BPMP guidelines to extend the life of the bridge and eliminate deficiencies per current and acceptable Caltrans standards. We will prepare draft spreadsheet of summary of the conditions and proposed repairs/maintenance work for sharing with the City to seek input before proceeding with estimates. When the extent of damages and deficiency are found to be severe, we will make recommendations regarding detailed analysis of a bridge using load rating and seismic analysis, updating and re-evaluation of SR, and preliminary recommending major rehabilitation/ replacement/ widening of a bridge using HBP funding. In case of severe structural damage or instability, we will advise the City of the issue and provide recommendations for temporary shoring and weight -limit posting, if necessary. Task #5: Preliminary Engineer's Estimate Upon confirmation of our propose solution for necessary repair/maintenance with the City, we proceed with performing detailed cost estimate. Our quantity estimates will be consistent with our propose solutions meet current standards and objectives of BPMP. The quantity estimates will include construction cost associated with bridge expansion joint or hinge repairs, deck rehabilitation and overlays, railing repairs, potential shoring of bridge during construction, traffic control, hazardous waste containment and disposal, and re -striping of the existing lanes after deck treatments. Task #6: Draft BPMP Report TTG will prepare a draft BPMP report to include: • Summary of field inspections with photos and sketches • Proposed maintenance/repairs • Proposed bridge candidates HBP funding with major retrofit/widening/replacement needs with revisions/ corrections of Sufficiency Rating "SR" using our special program for re -calculation of rating which is conforming to ASSHTO-NBI rating system. • Spreadsheet showing detailed calculations of quantities and estimates for each bridge including a score of each bridge. TTG's equation used for calculation of priority ranking score developed based on important factors such as bridge age, ADT, SR, SD/FO, quantity of damages and cost to repair. • Attachments including field forms, notes, sketches, original inspection reports as part of stand-alone documents • BPMP Sheet (Standard BPMP Sheet) which will be submitted to Caltrans and will include bridge priority ranking for maintenance and funding, county geographic location, name of implementing agency, bridge number, facility carried, feature intersected, location, sufficiency rating, SD/FO status, all Preventive .o.
