The purpose of this Construction Quality Assurance (CQA) Plan is to detail the testing methods and quality assurance procedures for required Water supply and sanitation projects. The Project includes:
• (Narrate the Summarized details of the Project)


For the purpose of the CQA Plan, the following terms are defined below:
Construction Quality Assurance (CQA) – A planned system of activities that provide assurance that materials or construction activities are undertaken and installed as specified in the drawings and specifications Construction Quality Control (CQC) – The process of measuring and controlling the characteristics of the item/product in order to meet the manufacturers or project specifications.
•(Give definition of other terms and materials used)


The participants and/or parties that have been identified as key personnel in the delivery of this project include, but are not necessarily limited to (Give the Positions of all key personnel in the project). The roles and responsibilities of the participants and/or parties are detailed below. For example
Project Manager
During the Construction, the Project Manager acting on behalf of the Employer, will serve as a single point of contact for the Design Engineer, Contractor and CQA Consultant.

Design Engineer

CQA Consultant
The CQA Consultant is an independent party not affiliated with the contractors, subcontractors, suppliers or manufacturers. The CQA Consultant may be the Design Engineer. The CQA Consultant has the overall responsibility for managing, coordinating and implementing the CQA activities and confirming that the contractor’s construction quality control activities are performed in accordance with the CQA Plan, construction drawings and technical specifications. The critical activities related to the construction, manufacture and installation water pipes, water pumps and

The CQA Plan must have cover page and Table of Content.
This role can be played by the Project Manager. However in large and complex projects another person may be appointed to take up this role. other project components will be monitored and documented by the CQA Consultant. The CQA Consultant will be responsible for issuing a Final Certification Report containing CQA documentation sufficient to satisfy regulatory requirements and the requirements of this CQA Plan.

The Contractor is responsible for the timely construction of the project, as detailed in the drawings and technical specification and in accordance with this CQA Plan. The Contractor is also responsible for the CQA. In particular, the Contractor shall ensure that:
•Only materials meeting the requirements set forth in the Technical Specifications and drawings are used; and
•The materials are installed in full conformance with the Technical Specifications and Design Drawings.

Soil Testing Laboratory
In the performance of the CQA activities, the CQA Consultant may engage YYYY Accredited soils testing laboratory, independent from the contractor, subcontractors, or any material supplier or manufacturer. The testing laboratory will conduct tests on representative samples to evaluate their properties and compliance with the technical specifications.



The works to be carried out under as given in the construction drawings, Bills of Quantities and Technical Specifications include, but are not limited to the following:
•[Identify and give detail breakdown of project major work tasks e.g. concreting, formwork, reinforcement work, excavation, drilling and pipe laying e.tc.]


Works shall be carried out as per prepared methods statements; works inspection at the site is to be conducted for each major work task using standard inspection checklist.
•[Use project specification documents, agreed standards and guidelines to develop method statements and inspection checklist for each major work task.]
For the purpose of enhancing monitoring of quality in daily activities, an Inspection Test Plan/schedule is prepared. The plan details the type of test/inspection for every activity in work schedule, test standard to be used, means of verification of the test, roles and responsibility of everyone involved.
•[Use project work schedule, method statements and agreed standards and guidelines to develop Inspection Test Plan]

All inspections and tests at the site shall be conducted through guidance as provided in the Inspection Testing Plan.


8 General

An effective CQA Plan recognizes all construction activities that should be monitored and assigns responsibility for monitoring each activity.. This is most accomplished and verified by the documentation of quality assurance activities. The CQA Consultant Manager will document that all quality assurance requirements have been satisfied. The CQA Manager Consultant will also maintain at the job site a complete file of construction drawings, technical specifications, CQA Plan, test procedures, daily logs and other pertinent documents.

9 Daily Record Keeping

Use the inspection and testing schedule/plan to Standard reporting procedures will include preparation of daily CQA documentation which, at a minimum, will consist of:
• Field notes, including memoranda of meetings and/or discussions with the Design Engineer or Project Manager;
• CQA consulting logs and testing data sheets; and
• Construction problems and solution summary sheets
. This information will be reviewed by the CQA Consultant, signed and transmitted to the Project Manager on a daily basis.
Monitoring logs and testing data sheets will be prepared daily. At a minimum, these logs and data sheets will include the following information:
• Date, project name and other identification;
• Data on weather conditions;
• A site plan showing work areas and locations selected for random CQA testing;
• Descriptions and locations of ongoing construction;
• Records of deliveries, condition, material roll numbers, description and locations of materials stores;
• Equipment and personnel in each work areas;
• Locations where in-site CQA tests and samples were taken;
• A summary of test results;
• Calibration of test equipment;
• An identifying sheet number for cross referencing and document control;
• Decisions made regarding acceptance of units of work and/or corrective actions to be taken; and
• Signature of CQA Consultant Representative.

10 Construction Issues

The contractor will be informed by the CQA Consultant about any significant recurring non-conformance with the construction drawings, technical specifications, or CQA Plan. The cause of the non-conformance will be determined and appropriate changes in procedures or specifications may be recommended. These changes will be submitted to the design engineer for approval. When changes are made and approved, they will become part of the construction documents.

11 Photographic Records

Photographs will be taken by the CQA Consultant and documented in order to serve as pictorial record of work progress, problems and mitigation activities. The basic file will contain colour prints and they will be identified with the date, time and location of the photograph.

12 Design and/or Specification Change

Design and/or specification changes may be required during construction. In such cases, the CQA Consultant will notify the Design Engineer, the Project Manager and the Contractor.


At the completion of the work, the CQA Consultant will submit to the Project Manager a signed final certification report. This report will document that:
• Work has been performed in compliance with the construction documents;
• Physical sampling and testing has been conducted at the appropriate frequencies specified in the CQA Plan;
• The required CQA documentation has been completed.
As a minimum, this report will include
• Materials and equipment manufacturers quality control documentation;
• A summary describing CQA activities and indicating compliance with the drawings and Technical Specifications;
