1. STATEMENT OF QUALIFICATIONS <br />d. Understanding of Need <br />Task #2• Site Visit and Documentation <br />As we have FHWA- certified bridge inspection, we will perform visual inspections and document the existing <br />bridge condition as necessary for FHWA- National Bridge Inventory(NBI) system as well as Caltrans and <br />AASHTO- Element Level Inspection system. The method of inspection and certification we have expertise <br />in is primarily for inspections needed in -line with condition assessment and damage investigation of in- <br />service bridges which is significantly different from new bridge construction inspection. <br />In certain cases such as extensive concrete deck cracking or potential delamination, we may choose <br />to perform non - destructive testing using advanced equipment or chain- dragging to confirm extent of <br />deterioration. <br />We will coordinate with the City traffic and maintenance division as well as OCFCD to obtain necessary <br />encroachment permit and access the bridges their approach roadway, channels. Our inspection work will be <br />performed with exercising full safety precautions and no anticipation of impact to traffic. If special inspection <br />is necessary using non - destruction testing equipment, it will be performed during very low traffic volumes <br />and under advanced permit for partial lane closures. <br />We have developed several field inspection forms and templates to be able to document bridge condition and <br />easily itemize and quantify the extent of damage /deteriorations. We will take necessary field measurements, <br />photo and videos if necessary to map/ sketch the bridge with extent of deterioration /damages to be able <br />to quantify the repairs /rehabilitation needs. We use laser devices or other advance measuring equipment <br />for reinforced concrete and steel sections. We will obtain sufficient field inspection data to be able to verify <br />Caltrans report, perform structural and service condition assessments, and quantity estimates needed for <br />BPMP. <br />Task #3: Evaluation of Existing Bridge <br />We will perform condition evaluation of the existing bridge regarding both structural and service /geometric <br />conditions, based on our field inspection of noted deficiencies as well as in -depth review of Caltrans reports, <br />field measurements of damaged joints, concrete deck cracking, section losses, corrosions, etc. as well as <br />geometric considerations such as roadway, median and shoulder width, and traffic congestions, traffic <br />accidents and damages to railings, flooding situations. <br />We will a clear understanding of the problems and issues associated with the damages/ deficiencies <br />determination of the causes and establish need to correct it. We will use our own developed Mathcad <br />programs or special spreadsheet program to re- evaluate /confirm Sufficiency Rating (SR) for bridges that <br />have significantly different condition than reported earlier by Caltrans, found to be "SD" or "FO" based on <br />our inspection have SR closer to 50 that may render them eligible for major rehabilitation or replacement, <br />as SR combined with condition flag "SD" or "FO" is a basis for eligibility for HBP funding. <br />Our assessment will determine if maintenance work is eligible for HBP reimbursement under BPMP such <br />as expansion joint seal and assembly replacement, methacrylate deck treatment, concrete overlays, deck <br />AC replacement/new installation, rehab or replace existing bearings, repair, restoration and strengthening <br />non I <br />... , , , , "' 25C -19 <br />
