HDPE - Construction Quality Assurance Plan

8. PROJECT CONTROL: ACTIVITIES, SCHEDULE, AND PROBLEM SOLUTION

8.1 Project Coordination Meetings

To guarantee high quality and smooth workflow during installation, clear, open channels of communication are essential. To that end, meetings are critical.

8.1.1 Resolution Meeting

Following the completion of the design, plans, specifications, and this CQA Plan for the project, a Resolution meeting will be held. This meeting will include all parties then involved, including the CQA Manager, the Project Manager, the Engineer, the General Contractor, and the Installer.

The purpose of this meeting is to begin planning for coordination of tasks, to anticipate any problems which might cause difficulties and delays in construction, and, above all, to present the CQA Plan to all of the parties involved. It is very important that the procedures regarding testing, repair, etc., be known and accepted by all. This site specific CQA Plan may be amended at the Resolution Meeting, after review by the CQA Consultant.

The first part of the Resolution Meeting may be devoted to a review of the design drawings and specifications. This is different from the peer review of the design, including design calculations, which would have been carried out previously.

This meeting should include all of the following activities:

review critical design details of the project;

review the Project Specifications;

review the CQA Plan;

review the Manufacturer's and Installer's QC Programs for compatibility with other project documents.

review the panel layout drawing;

make appropriate modifications to the CQA Plan to ensure that it identifies all necessary CQA;

make appropriate modifications to documents to ensure their integration and compatibility;

reach a consensus on the CQA and quality control procedures, especially on methods of determining acceptability of the HDPE geomembrane;

assign the responsibilities of each party;

decide the number of geomembrane seaming units to be maintained on-site by the Installer (this number depends on the number of seaming crews and on the type of seaming equipment);

establish work area security and health and safety protocols;

confirm location of nearest medical centre, hospital, and police station;

confirm the methods for documenting and reporting data, and for distributing documents and reports; and

confirm the lines of authority and communication.

The meeting will be chaired by the Project Manager and will be documented by a person designated at the beginning of the meeting, or by the CQA Consultant. Minutes will be transmitted to all parties by fax or email within 48 hours, and will be edited and returned to the Project Manager within a further 24 hours.

8.1.2 Pre-Construction Meeting

A Pre-Construction Meeting will be held at the site. At a minimum, the meeting will be attended by the Project Manager, the CQA Site Superintendent, the General Contractor, and the Installer. The meeting will be chaired by the Project Manager or designate.

Specific requirements for this meeting are to:

make any final modifications to the CQA Plan;

review the project specifications;

review the responsibilities of each party;

review and confirm lines of authority and communication;

review methods, forms and routing for documents and reports;

establish protocols for sampling and testing;

establish protocols for handling deficiencies, repairs, and retesting;

review the schedule for all operations;

establish rules for writing on the geomembrane, i.e., who is authorized to write, what can be written, and in which color;

outline procedures for packaging and storing archive samples;

review panel layout and numbering systems for panels and seams;

establish procedures for use of the seaming equipment;

finalize field cut-out sample sizes;

review qualifications of CQA Independent Laboratory;

review repair procedures;

review procedures for compensation allowance, treatment of wrinkles, and obtaining intimate contact between geomembrane and subgrade;

review activities and responsibilities associated with maintaining, dewatering, and filling the anchor trench;

consider environmental problems that could occur (excessive wind, rain etc.) and associated remedial activities;

conduct a site walk-around to verify that earthwork construction is proceeding on schedule, and to review material storage locations, and

obtain signatures on Installer Compliance certificate.

The meeting will be chaired by the Project Manager and will be documented by a person designated at the beginning of the meeting. Minutes will be transmitted to all parties within 24 hours, for approval and signature within a further 24 hours.

8.1.3 Progress Meetings

A weekly progress meeting will be held between the Project Manager and the CQA Site Superintendent, the Installer, the General Contractor, and any other concerned parties. The meeting will be chaired by the Project Manager or designate. Minutes will be recorded by the Project Manager or designate. This meeting will discuss current progress, planned activities, revisions to the work, and any new business. The CQA Site Superintendent will log any problems, decisions, or questions arising at this meeting in his/her daily reports. Any matter requiring action which is raised in this meeting will be reported to the appropriate parties. Minutes of the meeting will be circulated to all parties within 24 hours. Corrections must be made and submitted to the Project Manager within a further 24 hours.

8.1.4 Action Decision Meeting

The special meeting will be held when, and if, a problem or deficiency has occurred, or is likely to occur that requires special action decisions by several parties. The meeting will be attended by the Project Manager, the CQA Site Superintendent, and other involved parties. If the problem requires a design modification, the Design Engineer should also be present. The purpose of the meeting is to define and resolve the problem or work deficiency as follows:

Define the problem or deficiency;

Establish the cause;

Define possible solutions;

Select a suitable technical solution agreeable to all parties; and

Define an action plan to implement the solution.

The meeting will be chaired by the Project Manager and documented by a person designated at the meeting. Minutes will be transmitted to affected parties within 24 hours. Corrections must be made and submitted to the Project Manager within a further 24 hours.

8.2 Project Control Visits

Periodically, the construction site will be visited by the CQA Manager. This visit should, if necessary, be coordinated with a similar visit by the Project Manager. Regulatory officials may be informed of the dates of the visits if requested by the Owner, but only by the Project Manager.
