QUALITY ASSURANCE (QA) PROGRAM

The Natural Resources Conservation Service (NRCS) Quality Assurance Program will be conducted to assure that the specified contract quality of materials and workmanship is attained. The primary responsibility of the QA personnel is to observe the operations of the Contractor to assure compliance with the construction contract. This includes the physical examination of materials brought on to the site;

observation of the placement of materials; observation of the construction techniques; observation of quality control and construction management operations by the Contractor; periodic and continuous observation of construction work and ensuring proper safety measures are taken on-site.

The intensity of the examination is set forth in the WORK TO BE INSPECTED section of this plan.

Periodic quality assurance observations and checks of the Contractor's Quality Control work will be conducted to verify that measurable qualities of the work meet the contract requirements. Should quality assurance inspections indicate decreased quality of work; the quality assurance effort will be intensified until the Contractor's quality control program is performing in full compliance with the contract.

The following is considered the minimum amount of quality assurance inspection required:

1. An initial site walk-thru will be conducted to identify heavy equipment staging areas, safety signage locations and areas where pollution control measures will need to be in place. Periodic spot checking will be performed to ensure safety signage, heavy equipment traffic and parking are meeting requirements.

a) Pollution control facilities will be inspected for compliance to Construction Specification

402—Pollution Control, and for effectiveness to minimize sediment leaving the site. If water surfaces and streams are becoming muddy, identify the source and inform the

Contractor to make necessary corrections. Ensure that pollution control measures are in place before areas are disturbed.

2. Ensure the correct addresses have been marked and identified for demolition. Ensure trees to remain have been flagged prior to commencing clearing or demo activities.

3. Ensure OSHA safety measures are in place and Contractor is wearing hardhat at all times while in the construction work limits.

4. Observe excavation operations and all earthfill construction for compliance with the plans, the applicable specifications, and the safety requirements. Witness contractor’s fill placement measures to ensure proper compactions are being achieved. Observe dewatering of pits or basements if applicable.

5. Observe sealing of sewer mains and ensure methods follow City of West Haven requirements. Ensure

Contractor allows for proper sealant set time before backfilling trenches.

6. Observe and verify that any septic pumping or well decommissioning activities are performed by a qualified professional.

7. Obtain soil laboratory analysis from Contractor for approval by COR prior to obtaining sources of earthfill or topsoil. Verify source of topsoil on-site meets source approved by COR.

Verify seed tags on-site match seed mix approved by COR prior to seeding. Observe seed application follows prescribed application rate outlined in Conservation Practice Implementation
