QA/QC Program Overview November, 2015
Quality Roles on the Project • Construction Management Oversight (CMO-Turner) functions as the TJPA’s eyes and ears. • Construction Manager/General Contractor (CM/GC- WOJV) manages and directs the work. • Design Team sets Quality Standards during the design and specifications development. • Design team verifies standards through the submittal process and field observations. • Quality Control is the role of the CM/GC. • Quality Assurance is the role of the CMO including specialty inspection.
Overview of the CMO Services • “Construction management • Key Activities: services to coordinate, – Quality Assurance including administer, monitor, inspect and daily and code compliance interface with the Transbay inspections and coordination.

Quality Assurance – Prevent, Detect and Correct • Key Activities: • “Establish a quality assurance / quality control (QA/QC) plan and – Turner developed the QA Plan in implementing procedures…that accordance with Project meets requirements of the Program requirements, FTA requirements and Quality Management System, including compliance with the FTA’s Army Corp QMS best practices. – Quality Assurance and Quality Turner has updated the QA Plan Control Guidelines and the TJPA’s three times as work in the field has approved Quality Management changed during construction. System.” – QA Plan mandates observations, • “QA/QC plan and procedures shall inspections, corrective actions, provide for effective oversight of documentation and data collection. the CM/GC’s quality control plan…” – As part of the QA Plan, Turner has performed quality surveillances of the CM/GC and vital offsite surveillances at manufacturing facilities around the country .
Quality Assurance – Prevent, Detect and Correct • Key Activities: • “Development of appropriate inspection guidelines and – Implemented Autodesk BIM360 checklists, independent assurance (originally called Vela) quality tracking and sampling test guidelines, and inspection request system. formats for daily inspection reports – In the last year, there have been 2,737 and inspection and test Inspection Requests (IRs) from the documentation requirements.

All managed by Turner. conformance reporting and corrective action processes.” – To date, through daily observation, the • “Support for Program QA QA/QC team has identified, tracked and assisted in resolving over 1600 Field surveillance and audits of Condition Reports (“FCRs”) and over contractor, supplier and Contractor 140 Non Conformance Reports activities and products.” (“NCRs”). – Currently there are over 10,000 unique Inspection and Test records in the system.
Quality Assurance – Prevent, Detect and Correct • “Provide code and quality • Key Activities : inspections, on a timely basis in – Local and National Building Codes, the conformance with the structural engineer and National Construction Documents…” organizations such as the American Welding Society (AWS) and American Institute of • “Provide specialty inspections Steel Construction (AISC) mandate code and independent testing inspection and test requirements for steel including…steel, concrete, fabrication.

ISI has performed more than 2500 tests and inspections at a total of 16 offsite facilities to date.
Quality Assurance – Special Inspections and Tests • • Concrete Structural Steel (Non- – Visual Inspection for Destructive Testing) reinforcing steel placement, – Visual Inspection. embedded item placement – Ultrasonic testing. and cast-in item placement. – Magnetic particle testing. – Slump testing. – Torque testing. – Air testing. – Decking and Nelson Stud – Temperature testing. welding inspection. – Shrinkage testing. – Pull testing. – Compression testing. • Soil Testing • Future Testing – Nuclear gauge testing – Fireproofing testing.

• The Transbay Transit Center Construction Quality Control (CQC) Program is a blend of the FTA 15 Essential requirements of the FTA Elements QMS 2012 15 Essential USACOE Elements & the Army QM Corp of Engineers’ System Contractor Quality Management System. • The Program has been in place during the design Transbay Quality and construction process. Program • Updated to address design assist packages.
