QUALITY SYSTEMS - QA/QC


Quality Control (QC)

Quality Control is defined as the operational techniques and the activities used to keep the quality of inputs or outputs to specifications; to fulfill and verify requirements of quality.

Quality Assurance (QA)

Quality Assurance refers to those actions, procedures, and methods employed at the management and senior technical levels to observe and ensure that prudent quality procedures are in place and are being carried out and that the desired result of a quality product is achieved.

The QA/QC program is a process of continuous improvement which requires updating the information and processes for better adherence.

This QA/QC system shall include:

  • Documented quality system procedures and instructions to ensure that all activities are performed in accordance with established requirements;
  • Effective on-site support to ensure compliance and the use of the QA/QC procedures and instructions.
  • Clarification of the standards of acceptability as required supporting the overall QA/QC program
  • Effective maintenance of quality records to document and track performance and improvement.
  • Review of the project process, construction methodologies, inspection, and test procedures to ensure that applicable documentation reflects how activities are actually performed

MANAGEMENT RESPONSIBILITY
The responsibility matrix in adhering to the QA/QC lies with all the staff and management will ensure that the same is understood, implemented and observed at all levels of the organization
Quality control and Quality Assurance is followed diligently at all levels of the organization and at all verticals.

DESIGN VERTICALS
Structural & Quantity Surveying:

  • Adhering to the standard operating processes that have been inculcated as part of the quality control measure;
  • Cross auditing of designs and drawings by internal teams for validating the final result is on the desired lines;
  • Follow a set of to work methodologies on the design, based on the inputs shared from the client/architect and documentation of the same;
  • Implement strong technical sense into the design development to arrive at optimal solutions;
  • Following the architectural intent, the structural drawings and detailing issued as GOOD FOR CONSTRUCTION is thoroughly validated for its correctness;
  • Cost optimization based on the available data and reverse engineering to achieve the desired cost per Sq.ft;
  • Documentation of the quantities thus arrived for all future reference and thus initiating a continual innovation and up gradation of costing methods;
  • Standard procedures followed to minimize the variations in quantity estimations as issued at the preliminary stage to the final quantities.

SITE EXECUTION SUPPORT
The responsibilities of the QA/QC engineer or manager that supervises, inspects and/or verifies the work affecting quality are:

  • Initiate action to prevent the occurrence of work or service nonconformity during the routine site visits;
  • Identify and record any quality problems through audit reports;
  • Initiate, recommend, or provide solutions to address the deviation;
  • Verify the implementation of solutions;
  • Issue of non-conformance reports;
  • Material approval accorded as against the standard test results and advice with relevant inferences when there is conflict in outcome;
  • Documented work instructions defining the manner of executing the work to ensure that an acceptable level of quality is maintained at all times. The instructions shall also specify equipment, materials, skills and working environments required to comply with applicable standards, codes, and quality plans;
  • Monitoring and control of suitable process and work characteristics during execution of the work;
  • Clear identification of the required approval of processes;
  • Specific Activity Process Controls are for activities where the results cannot be fully verified by subsequent inspection and testing. Accordingly, continuous monitoring and / or compliance with documented procedures are required to ensure that the specified requirements are met.

 
MEP Services:

  • Adhering to the standard operating processes that have been inculcated as part of the quality control/quality assurance process;
  • Diligent review of options suggested before the same is being sought approval for;
  • Through review of architectural intent through hierarchy is followed before a suitable recommendation is made adhering to the
  • Various levels of scrutiny measures as part of QA/QC measures are implemented before the design detailing and final services inputs are recommended;
  • Internal training as a continual process to update and upgrade the team on the latest developments;
  • Cross auditing of designs and drawings by internal teams for validating the final result is on the desired lines;
  • Follow a set of to work methodologies on the design, based on the inputs shared from the client/architect and documentation of the same;
  • Implement strong technical sense into the design development to arrive at optimal solutions;
  • Following the architectural intent, the structural drawings and detailing issued as GOOD FOR CONSTRUCTION is thoroughly validated for its correctness;

 

EXTENDED QUALITY SYSTEMS- QA/QC
CONTROL OF PROJECT RELATED DOCUMENTS
Upon award, each project is assigned a project number and the

  • Design Manager/Design Coordinator establishes a "Project Job Folder".
  • This folder shall contain a complete set of all project related documents, specifications, drawings, etc.
  • All information generated during the life of the project shall be maintained in this job folder.
  • A listing shall be made of all drawings, specifications and other data, etc. that are to be submitted to the client/architect for review and approval.
  • A copy of all documents returned by the client approved, or approved as noted, shall be maintained in the job folder. Once approved, the complete set of Good for Construction drawings shall be maintained in the same job folder.
  • As a QC adherence, we recommend a complete set of all documents required for proper execution of the work shall be maintained at the project site.
  • Any revisions shall be immediately updated and/or supersede the existing version of drawings at the project site for use while executing the project.
  • Any field changes to the work shall be properly noted on the project site set of the drawings and prior concurrence sought before execution of work. The project site set of the drawings shall show the work exactly as the work was built.

MATERIAL CERTIFICATION & TRACEABILITY
All construction materials such as

  • Cement,
  • Sand,
  • Concrete and
  • Reinforcement steel,
  • Waterproofing compounds and materials,
  • Expansion joint filling materials,
  • Water swelling bars etc.

That will be used during the construction of the building shall be sought a prior approval on the vendor credentials, source of materials, third party test reports and actual trial test results (wherever applicable) to be verified and approved and retained a copy for further reference before according consent.


PROCESS CONTROLS
The controlled conditions recommended for work execution shall include the following:

  • INSPECTION AND TESTING DURING CONSTRUCTION
    • All inspection and testing activities are performed in accordance with the quality plan and documented procedures;
    • Ensure specification and drawing conformance by the use of established process monitoring and control methods;
    • Ensure that all required inspections and tests have been completed and necessary reports have been received and verified before the finished work is released to the client.
    • Identify and issue corrective measures any nonconforming work.
  • FINAL INSPECTION AND TESTING
    • The quality plan or documented procedures for final inspection and testing require that all specified inspection and tests, including those specified either by established quality procedures or the client, are carried out and that the work meets specified requirements.
    • Recommend the Project Manager shall ensure that all final inspections and testing activities are in accordance with the quality plan and documented procedures. Upon completion, all associated data and documentation shall be properly filed in the project QA/QC folder and submitted to the client/Consultants as required.
  • INSPECTION AND TEST RECORDS
    • The Project Manager/QC Lead shall ensure that all records which give evidence that the work has passed specified inspection and / or testing acceptance criteria are maintained in the project QA/QC folder for future reference.
