The Inspection and Test Plan (ITP) for Cement Plastering Works defines the systematic quality-control process to be followed during surface preparation, plaster application, finishing, curing, and verification. This ITP ensures that all plastering works comply with the project specifications, approved materials, IS standards, and the approved method statement.
This document outlines the inspection stages, acceptance criteria, method of verification, frequency of inspections, and responsibilities of Contractor, Inspection Party, and Client/Consultant.
WHAT IS AN INSPECTION AND TEST PLAN (ITP)
Inspection and Test Plans and checklists are integral parts of quality management systems — not only in construction but in almost every industry where Quality Management Systems (QMS) are implemented.
They are considered master documents through which various parameters and activities of a process are monitored and recorded. These records later play a vital role during verification and auditing.
In construction, where numerous trades and activities must be completed — such as structural, finishes, façade, electrical, mechanical, and plumbing works — preparation and implementation of different ITPs form a crucial part of the project quality management system.

INSPECTION AND TEST PLAN FOR CEMENT PLASTERING WORKS
SECTION 1 – DOCUMENTATION REVIEW
This section outlines the review and approval process for all necessary documents before commencing Cement Plastering works on-site.
Key documents include:
- Approved drawings and typical details
- Material Submittals
- Method Statement
SECTION 2 – INSPECTION OF INCOMING MATERIALS
This section addresses the inspection of materials used for cement plastering
Points to verify:
- Materials conform to approved specifications
- Materials are tested and conform to applicable specifications
Materials are stored as per the required guidelines and standards
SECTION 3 – PRE-PLASTERING INSPECTION
This section focuses on inspections to be carried out before the plastering work begins to ensure all prerequisites are met
Checks include:
- Check on materials
- Check on the Block/Brick works for plastering.
- Check on the concrete surface for plastering.
- Check on plastering guide spot/dabs
- Check on chicken mesh/metal laths
- Check on scaffolding
- Check on surface for plastering
- Check for MEP clearance of the area
These checks help ensure accuracy, consistency, and readiness before plastering starts.
SECTION 4 – PLASTERING WORK IN PROGRESS INSPECTION
During Plastering, regular inspection to ensure that the work meets acceptable quality standards.
Checks typically include:
- Check for mixing of plaster.
- Check on the use of mixed mortar
- Check during application
- Check on control/expansion joints if any
- Check for finishing
- Check for floated finish for external finish
- Check for smooth plaster finish
These inspections help prevent defects and ensure that welded joints meet structural and quality requirements.
SECTION 5 – POST-PLASTERING INSPECTION
After Plastering is completed, inspection ensures that the finished area for
Checks include:
- Check for level, square and plumb.
- Check for curing.
