CQA ACTIVITIES:
SUMMARY:
The CQA activities performed consisted of observing, documenting and recording the construction
activities of the contractor. Field observations within the northwest portion of the VLF included stripping
of all frozen and unsuitable materials and placement of structural fill using the method specification as
outlined in the Project Documents. Fill placement during the week was intermittent due to the LOB
Delivery Road work being the major activity.
