Common use of Construction Requirements Clause in Contracts

Construction Requirements. All construction and materials shall be in accordance with the NCDOT 2018 Standard Specifications for Roads and Structures and current NCDOT Project Special Provisions unless noted otherwise elsewhere in this RFP. The Design-Build Team shall be responsible for investigating, proposing and incorporating remedial measures for any construction problems related to foundations, retaining walls, subgrades, settlement, slopes, and construction vibrations. Submit the proposed remedial measures to the Geotechnical Engineering Unit for review and acceptance prior to incorporation. The Design-Build Team shall be responsible for any damage or claim caused by construction, including damage caused by vibration (see 2018 Standard Specifications for Roads and Structures Article 107-14). The Design-Build Team shall be responsible for deciding what additional, if any, pre and post-construction monitoring and inventories need to be conducted to satisfy their liability concerns. Any monitoring and inventory work shall be performed by a qualified private engineering firm experienced in the effects of construction on existing structures. The prequalified geotechnical firm that prepared the original foundation designs shall perform any changes to the foundation designs. All changes shall be based upon additional information, subsurface investigation and / or testing. Send copies of revised designs, including additional subsurface information, calculations and any other supporting documentation sealed by a professional engineer registered in the State of North Carolina, to the NCDOT for review and acceptance. The prequalified geotechnical firm which prepares the foundation designs shall review and approve all pile driving hammers and drilled pier construction sequences. After the prequalified geotechnical firm has approved these submittals, the Design-Build Team shall submit them to the NCDOT for review and acceptance prior to beginning construction. Hammer approvals shall be submitted prior to performing any pile driving and shall be performed using GRLWEAP Version 2010 or later. Limit driving stresses in accordance with the AASHTO LRFD Bridge Design Specifications. If a tip elevation is noted on the plans, drive piles to the minimum required driving resistance and tip elevation. Drive piles to the minimum required driving resistance and a penetration into natural ground or below design scour of at least 10 ft. If a pile is socketed into rock (as defined in Section 411-1 of the 2018 Standard Specifications for Roads and Structures) at least 5 feet and all other design requirements are met then the total penetration amount may be relaxed at the discretion of the Geotechnical Engineering Unit. Unless otherwise approved, stop driving piles when refusal is reached. Refusal is defined as 240 blows per foot or any equivalent set. Perform Pile Driving Analyzer (PDA) testing on at least one pile per bridge using a NCDOT prequalified company to perform the testing and develop pile driving criteria. PDA testing should confirm the highest required driving resistance for the bridge if only one test is to be performed. Additional PDA tests may be required based upon the AASHTO LFRD Bridge Design Specifications and/or the judgement of the geotechnical engineer. Provide additional PDA testing for any revisions to pile type, size or hammer previously approved. The locations of specific piles to be tested must be accepted by the NCDOT prior to any PDA test. Analyze data with the Case Pile Wave Analysis Program (CAPWAP), version 2006 or later. At a minimum, analysis is required for a hammer blow near the end of initial drive and for each restrike and redrive. Additional CAPWAP analysis may be required as determined by the Engineer. Meet the guidelines for NCDOT PDA reports from the Geotechnical Engineering Testing Contract for PDA test reports. To obtain a list of pre-approved Geotechnical Engineering Testing Contract companies to perform PDA testing and guidelines for PDA test report, contact the Geotechnical Engineering Unit at 000-000-0000. PDA testing shall be performed in accordance with Section 450 of the Standard Specifications. Submit a complete PDA report sealed by the professional engineer who performed the test to the foundation design firm. The foundation design firm shall develop pile driving inspection charts or tables for acceptance by the NCDOT prior to pile installation. Send copies of any inspection forms related to foundations, embankment, and subgrade to the NCDOT for review.
