CONSTRUCTION QUALITY CONTROL/QUALITY ASSURANCE PLAN:
PROJECT :
The Upper Hudson River is defined as the section of river from the Fenimore Bridge in Hudson Falls to the Federal Dam at Troy, New York. The ROD calls for, among other things, a remedial action to remove and dispose of sediments from the Upper Hudson River. Sediments to be removed are defined based on the PCB mass per unit area (MPA) and surface concentration or characteristic criteria (EPA, 2002).
EPA defined three sections of the Upper Hudson River for the sediment remediation activities outlined in the 2002 ROD:
River Section 1: Former location of Fort Edward Dam to Thompson Island Dam (TID) (from river mile [RM] 194.8 to RM 188.5; approximately 6.3 river miles);
River Section 2: TID to Northumberland Dam (from RM 188.5 to RM 183.4; approximately 5.1 river miles); and
River Section 3: Northumberland Dam to the Federal Dam at Troy (from RM 183.4 to RM 153.9; approximately 29.5 river miles).
The remedial action is to be conducted in two phases, designated Phase 1 and Phase 2. Phase 1 is defined as the first year of dredging and will be completed in a portion of River Section 1. Phase 1 also includes preparation of the land-based sediment processing facility. Phase 2 covers the remaining dredging in the three river sections.
1.2 PHASE 1 CONTRACTS DESCRIPTION :
The project scope for Phase 1 activities will be conducted under at least seven separate contracts (excluding the rail transport and disposal contracts as well as agreements with the originating rail carrier for infrastructure improvements) and three separate Remedial Action Work Plans (RAWPs). The contracts and RAWPs are described below and summarized in Table 1-1. The table also includes the relationship of construction quality assurance (QA), quality control (QC) and health and safety to other Phase 1 activities.
Remedial Action Work Plan for Phase 1 Facility Site Work Construction (Parsons, 2007). These activities include the following:
Contract 1 – Facility Site Work Construction includes general civil work, such as grading, placement and compaction of fill and paving. Other work activities include wharf area construction, access road construction, river mooring installation and construction of a support marina.
Contract 2 – Rail Yard Construction includes rail construction on the processing facility site property, and within the right-of-way of the commercial rail carrier, and rail yard facilities work.
The activities to be performed under Contract 3A – Processing Equipment Installation will be described in RAWP #2, Remedial Action Work Plan for Phase 1 Processing Equipment Installation and Remaining Site Work. RAWP #2 covers the remaining site work, such as processing facility buildings, and the installation of process equipment, piping, electrical, instrumentation, communications, and the commissioning of the systems.
Briefly, Remedial Action Work Plan Covers The Following:
Contract 3 – Processing Facility Operations, including barge offloading, coarse material separation, sediment dewatering, water treatment (process and storm water), storm water management, and staging area management and maintenance. In the off season (when the Champlain Canal is closed), the contractor will winterize the processing facility and operate and maintain the storm water collection and treatment system.
Contract 4 – Dredging Operations, including re suspension containment system installation, debris removal, the performance of inventory and residual dredging operations and the transport of loaded sediment barges to the off-loading wharf at the processing facility. After dredging is completed in an area, the contractor will place appropriate back fill, cap, or shoreline stabilization structures.
Contract 5 – Habitat Construction, including the supply and planting of sub aquatic vegetation in certain dredged areas pursuant to habitat reconstruction plans.
Contract 6 – Rail Yard Operations, including all activities required to operate and maintain the rail yard. This primarily will involve the loading of debris, coarse material and dewatered sediment into empty rail cars, setting up of outbound loaded trains, and receiving of inbound empty trains.
QUALITY MANAGEMENT PLAN
Parsons Engineering of New York, Inc. (Parsons) has been retained to provide construction management services for this project. As GE’s managing contractor, Parsons will carry out work on this project in accordance with the Parsons Quality Management Plan (QMP) (Parsons, 2005), which was submitted to EPA on November 1, 2005.
Construction Quality Control / Quality Assurance Plan Organization:
This CQAP is organized into eleven sections.
Section 1 - Introduction: describes the project setting, the Phase 1 contracts and related RAWPs, and the CQAP quality program overview.
Section 2 - Project QC/QA Organization: presents the organizations and key personnel involved in the construction of the RA, their responsibilities and authorities, the structure of the QC/QA organization and the minimum training and experience of the Construction Quality Assurance Officer (CQAO) and personnel.
Section 3 - Submittals: presents the procedures for processing submittals from Phase 1 contractors and vendors.
Section 4 - Performance Monitoring Requirements: addresses QC/QA for performance monitoring requirements applicable to Phase 1 FSWC and PEI.
Section 5 - Inspection and Verification Activities: provides procedures for tracking construction inspection and verification activities for the contract, construction acceptance criteria, and construction audits.
Section 6 - Construction Deficiencies: describes the procedures for tracking construction deficiencies from identification through acceptable corrective action.
Section 7 - Documentation: describes the procedures for the project documents that will be managed through a combination of a secure document filing and storage system and computerized Document Tracking System.
Section 8 - EPA Approvals: describes EPA approvals applicable to the Phase 1 FSWC and PEI QC/QA.
Section 9 - Field Changes: describes handling of quality plan changes to assure QC/QA objectives are met.
