How to implement effective quality control in construction projects
Quality assurance has always been an essential part of construction and any other form of project.
This means that adhering to proper quality control measures helps to see to it that the end product of the completed project meets all the required norms as far as safety, functionality, durability, and appearance are concerned.
Ensuring the quality of the work done at every step during the construction of a project helps to prevent or solve problems at an early stage, as opposed to when the construction is complete and errors come to light. Following these instructions in the letter when executing this article will help you develop a proper quality control plan for your construction estimating companies project.
Planning for quality
The first approach is to establish a quality control plan before the construction estimation service and during project design or planning. This should outline:
- Quality standards – Identify from building codes, specifications, or industry norms absolute measures in terms of material quality, workmanship, or finished product that must be met.
- Inspection schedule – Decide on points within construction where the work will be checked to ensure that it meets certain quality standards before it continues.
- Documentation processes – This involves setting up forms for documentation such as inspection reports, test logs, and non-conformance reports among others that will act as a record of the quality problems and the solutions to them.
- QCP personnel – Determine the employees assigned to perform quality control, inspection, and surveillance for each construction process.
- Dissemination/escalation – Detail processes for reporting other quality issues to the appropriate individuals/stakeholders and reporting major non-compliance events.
When construction starts, it is possible to control difficulties arising from quality control responsibilities, oversight, documentation, and accountability if these issues have been planned earlier.
Implementing inspection and testing
Once construction estimating service starts, perform regular checks and verification at QC sanction points to identify problems at an early stage. Typical inspection activities include:
- Inspection of material for ascertaining conformance to required grades, strength, chemical composition, dimensions, etc. for its use in the work.
- Checking substructure works, and concrete preparation such as excavations, formwork, reinforcement bar placement, backing fixture, and other preparatory works before releasing subsequent phases.
- Verifying that the installed work corresponds to the design plans and details for elements such as concrete size, pipe gradient, wall plumb, equipment orientation, etc.
- Inspecting workmanship to check whether or not installations met the appropriate levels of craftsmanship.
Perform inspection and testing by professional personnel to come up with quantitative measures of the quality of some elements such as the densities of the soil, the concrete strength, pipe leakage, continuity of cables, etc. Keep records of the results of all the inspections and testing conducted.
Enforcing quality standards
When an inspection uncovers additional work that does not meet acceptable quality, the first course of action is to inform the contractor of deficiencies or to request improvement in work procedures. For significant recurring noncompliance or major defects, stronger remediation directives may be necessary, including:
- Sending out formal letters of non-compliance
- Pausing work-related responsibilities until a decision is made
- When it comes to specific aspects, it is necessary to demand to remove and replace whole sections of unacceptable work.
- Withholding payment
Another reason is that quality issues must be addressed as soon as possible to avoid further construction of substandard quality or the addition of new layers of inferior quality to existing structures. Nevertheless, ensure that you follow pre-determined escalation procedures as soon as the contractor has not solved issues satisfactorily.
Quality document management
All inspections and tests about quality control, any notice, response, and corrective action taken must be recorded. Common documentation systems include:
- Inspection checklists and reports: Document measurements, comments, deviations, violation notices, relevant standards, etc Keep copies of such records and distribute them to contractors with the instructions for rectification.
- Testing logs: Test information such as the places where testing will be done, the dates on which tests will be conducted, the methods and equipment to be used, the people who will conduct tests and record results, results compared to specifications, and test failures/retests.
- Non-compliance notices: Written records in a contractual form notifying contractors of the violations of the standards and the necessary corrective measures. Track through to resolution.
- Daily logs: Every day onsite supervisors record the tests carried out, the inspections made, the deficiencies noted, the contractors involved, and the status of corrections.
Also, keep all documents more organized in project files and databases so that when issues are raised in the future, the professional can easily provide records and prove compliance.
Quality control analytics
Accurate inspection and testing data foster useful analytics when collected consistently. Track metrics like:
- Conveyance rates of noncompliance with various work processes, tools, materials, etc., point to areas that need particular attention in the organization.
- Time taken on average to issue out notices, implement fixes, and close the issues—more extended periods indicate a slow action plan.
- Frequency and time-space characteristics of certain defect classes.
- Any additional time spent on construction elements that could be directly or indirectly linked to quality issues that have not been resolved.
Thus, the mentioned analytics help to optimize the process within the given project and in further quality assurance agendas.
Complete construction projects on time
Controlling quality involves the early planning of quality requirements, the validation inspections, and testing, proper documentation of all construction activities, and the implementation of measures to address nonconformities, which can ensure safe, functional, and attractive structures at the construction estimating services site.
Setting up these responsibilities makes contractors more responsible and documented details serve to bring legal credibility when issues of quality surface at a later date. Implementing the aspects of quality control discussed above will result in the overall accomplishment of construction projects that are constructed within the stipulated time, and cost and to optimum standard.
