Rejacking and crack mapping activities were performed, as required, by the project procedures.

Assessment Team Observations The Stone & Webster CIO Team has completed their Phase III overview of the civil documents at the five Documen,t Control Stations associated with the Soils Remedial activities. As a result of the overview , Stone & Webster issued an NIR detailing nonconformances found at three of the five Document Control Stations. MPQAD issued a QAR based on nonconformances detailed in the NIR. Once the QAR is satisfactorily resolved, Stone & Webster will conduct another overview of the Soils Document Control stations.

An MPQAD audit noted document control problems similar to those identified in the NIR resulting in the preparation of a CPCo Management Corrective Action - '

Request / Report. The purpose of this report is to initiate evaluation of recurring document control problems.

An update on corrective actions being undertaken by US Testing was provided by Bechtel. A review of US Testing by Bechtel Field Engineering found that

2 J.O. No. 14358 Midland Plant Units 1 & 2 Independent Assessment of Underpinning most of the corrective action items have been implemented by US Testing.

Cross training of US Testing personnel and development of Work Instructions are the two major items that are still open. Bechtel reported that a revised schedule would be provided next week targeting completion dates for cross referencing of inspectors and development of work instructions. The Assessment Team believes that US Testing should strive to complete the work on these two items in accordance with the revised schedule.
