Plans, coordinates, prepares, performs, and directs assurance inspection procedures for a project including: prefabrication inspection of plant facilities and processes; base materials inspection and testing, production welding inspection and testing, design or laydown inspection; on the basis of structure design by comparing the structure design and contract provisions to specified codes, standards, and specifications and determining the necessary assurance inspection procedures to be used throughout the fabrication process in order to apprise effected parties of the various inspection procedures, to establish the project log, and to preclude possible fabrication problems.

Inspects: welding operations to insure the quality of weldments by verifying that only qualified welders, welding operators, or tackers weld on components and employ approved materials and procedures in accordance with project design plans, standard specifications, and special provisions; heat curving and straightening of components to assure compliance with standards and specifications relative to attainment of critical temperatures by visually observing the process and determining tolerances using temperature sensitive crayons; and the preparation of surfaces by visually observing ambient conditions, the sandblasting and cleaning of fabricated components, and examining results to assure a clean and smooth surface for proper adhesion of paint, when applied, and determining the thickness of applied paint and other films by measuring with a micro-test gauge for conformance to the specified film thickness and assuring the use of certified materials.

Accepts or rejects fabricated components, production materials, facilities, equipment, processes, and personnel qualifications throughout the various inspection phases by: determining compliance with tolerances detailed in contract design plans, specifications, and/or standard practices; advises the bridge and/or materials project engineer of any design problems, shop discrepancies, and/or materials problems exceeding tolerances by communicating in a timely manner, via telephone, the problems encountered and requesting prescribed corrective procedures; and initiates and monitors the prescribed corrective measures and logs the results in the project diary for subsequent inclusion in the final project report to insure production quality and compliance.

Monitors, reviews, interprets, and/or performs nondestructive testing including radiography, magnetic particle, liquid penetrant, and ultrasonics to assure conformance to the contract specified codes, standard specifications, and special provisions by witnessing the processes and results of testing and verifying current certification of personnel performing testing; in order to determine that weldments are free of defects which could be detrimental to the performance of the structure.

Performs design inspection (laydown) of the fabricated components during assembly to insure conformance to design drawings by making physical dimensional checks of camber, sweep, and designed thickness of fabricated components through the use of tape measures, stringlines, rules, and transits.

Visually inspects and records quantity and quality of metal products received at contractor plant for project fabrication by: verifying the actual number of plates, heat numbers, and dimensions of the materials using rules, tapes, and calipers to contractor certified purchase orders; and comparing certified steel mill test results to specifications to insure that physical and chemical properties of the materials fall within acceptable limits in order to document the level of prepayment for materials to be used in the fabrication process and assure compliance to contract provisions.

Prepares a final narrative report in order to document all areas of inspection (materials, welding shop, and design) performed during the fabrication process and to verify that all inspections were satisfactory, or were corrected satisfactorily, by expanding information included in the project diary and submitting the report to the central laboratory, Bridge Design office, and the engineers responsible for project administration.

Visually inspects the various fabrication processes of a structure by observing on a daily basis the grinding, burning, sawing, planing, drilling, milling, fitting, heating, bending, and punching of components in order to insure conformance to tolerances as specified by contract documents.

Monitors the quality control functions of the fabricator by reviewing report forms and/or inspection documents to determine conformance with codes, standards, specifications, and special provisions.

Administers welding procedure tests and welding operator tests by observing the welding process, recording welding parameters, and submitting weld test plates to the central laboratory for testing review in order to certify contractor personnel and procedures used in the fabrication of structural steel components.

Maintains and documents heat number identity of main members of the steel structure through the fabrication process to insure design and specification conformance.

Secures samples of bolts, nuts, washers, and other miscellaneous structural materials, not accepted on a certification basis, in order to submit materials to the Central Laboratory for testing and approval prior to use.

Recommends as necessary revisions of standard inspection and testing procedures, repair procedures, design detailing practices, standard specifications, and special provisions associated with the fabrication of structural metal materials to appropriate engineering personnel.

Performs, in accordance with set procedures, policies, and standards, such duties as instructing technical subordinates about tasks, answering questions about procedures and policies, distributing and balancing the workload, and checking work.
