The Way To Create A Site Inspection And Testing Plan For Construction Activities

The primary purpose of an Inspection and Testing Plan (ITP) to get a construction project is always to have a straightforward solitary document that reports all inspection and testing wants associated with a particular construction activity or procedure. For example, on a construction project, it could be the construction of a foundation, an excavation or the concreting of a section in the superstructure, procurement of construction materials or usage of plant and machinery. Similarly, the ITP not merely clearly defines the work as well as the supplies to become inspected and tested but additionally indicates who’s responsible for ITP functions including when, where and how it has to be carried out.

In addtion, it has Hold and Witness Points, sources to applicable standards, acceptance or rejection guidelines as well as the precise record keeping and reporting specifications. Therefore, a well prepared ITP can be implemented successfully although making certain any construction activity has the required quality and workmanship in accordance with relevant standards. Most importantly, an ITP envisions appropriate record keeping which ensure traceability that is a mandatory requirement in any Quality Control/Assurance system for example ISO9000:2002.

Generally, the main contractor within a construction project is responsible for creating and implementing appropriate ITPs. Similarly, the main contractor is accountable for ITPs for the construction actions carried out by its sub-contractors. It really is mandatory to appoint a senior responsible person; from the contractors side; on creating and approving or subsequent modifications to ITP for any project. He/she who is appointed ought to be effectively experienced and possess sound practical knowledge on the all elements of construction. A lot more importantly, this responsible person must know how you can submit compliance as well as a conformity certification to the client including what corrective measures or responses are needed to resolve any non-conformity concern.

The actions involved in building an appropriate Inspection and Testing Plans for a construction project are:

All involved in creating an ITP must have thorough familiarization with all the contract documents and related technical specifications. In other words, he/she ought to have a thorough knowledge of contractual clauses and obligations (pertaining to testing and inspection) topic for the prevailing contract.
Prepare a detailed list of any ambiguities or inconsistencies or lack of information and specifications pertaining to raw supplies and workmanship.
Inform the Client or Clients Representatives such shortcomings in writing prior to commencement of any activity.
Study the scope of work or the Bill of Quantities in detail. Later, prepare a list of areas that demand an ITP. It really is usually a good practice to prepare separate ITPs for each and every work location or trade or section.
Decide on the Hold and Witness Points stipulated within the contract which includes any subsequent directions given by the Client or Clients Representatives.
Prioritize the locations or requirements that may have a significant impact on the quality from the final work or product. When preparing such priority list one should ask what if questions to be able to ascertain the influence on the final quality as well as the acceptance of the item or work in case of non-conformity. Be certain to contain any references to tests, submitting information for the client, getting approvals and deciding on Hold and Witness Points.
Once the places or items are prioritized depending on the implications resulting from non-conformity, it is essential to prepare person ITPs for every prioritized area to ensure that detailed checklists and recording on inspection and testing are determined.
Share the ready checklist and also the recording with other individuals who are related using the particular construction. Depending on the positive and negative inputs given by the construction team, the proposed ITPs will have to be revised to ensure wider acceptance (by the construction team) which will enable smooth implementation of ITPs with out any snags.
Prepare every ITP with reference to contract document as well as the Quality Management System (QMS) if it is already in location.
Timely submission of every ITP as well as the associated certification towards the Client is essential, so that he/she has sufficient time to comment before commencement of any work or activity earmarked beneath the ITP. The comments given by the Client has to become noted and have to be included within the ITP. If it is not achievable, it has to be notified for the client in writing with out delay.
It is essential to separate all work locations from the construction project so that appropriate control and monitoring of ITP actions are feasible. It is far better to mark these places on drawings or included in a schedule.
Release ITP checklists for each construction work region or sections included inside the schedule or marked place on the drawings.
Create awareness (by way of coaching) on each and every ITP among those who are directly responsible or involved in it. A clear process has to be place in spot for prior notification of Hold & Witness Point for the right individual.
Finally implement every ITP (Inspection & Testing) while notifying the respective customers and regulatory authorities who are responsible for Hold & Witness Points. Maintain correct recording of ITP results on checklists which are approved by the responsible persons.

On reviewing the above mentioned, it is noted that when developing an effective ITP to get a construction activity, one has to essentially address the next:

What, when and how to test?
The type of construction activity and its complexity.
Ease of inspections and sampling
The severity of non-conformity or failure: cost of rectification, the effect on construction progress, ease of rectification, the effect of failure on other elements as well as the threat to worker safety including the public.
Finally the resource availability.

Inspection And Testing To Ensure The Quality Of Finish Product In Construction Works

Top quality assurance in construction activities is obtained via the execution of Inspection and test plans (ITPs). ITPs are designed for each and every construction activity depending on the technical specs necessary for such activity.

The actual Objective of Inspection and Testing Plan

An Inspection and Test Strategy (ITP) is an essential component within a QA system within a construction project. It is a document that defines and records all inspection and testing needs of any certain construction activity or procedure. As an example, in a construction project it may be either a construction activity or perhaps a specific component of work or possibly a trade or possibly a production work.

Particularly, ITP defines:

The construction activities and related work practices, work items and materials to become inspected or tested,
Who is accountable for inspection and testing and at what stage and the frequency of inspection and testing must be carried out;
Hold and Witness Points (a point or stage beyond which work activity ought to not proceed with out the approval in the client or the clients representatives)
Applicable requirements, acceptance benchmarks and the records to be maintained;

The reason why an ITP is needed in Construction?

Typically the Inspection and Testing Plan (ITP) may be the principal document that essentially controls the top quality of all activities and operations in any construction project. ITPs must not just be accepted by all parties involved within the project but additionally must be introduced at the inception from the construction project.

The actual ITP should address the following:

Exactly what are the quality targets to become achieved in terms of technical and contract specifications (or conditions) of the construction project;
Who will likely be accountable for inspection and testing and their responsibilities in terms of the contract
Exactly what are techniques, procedures and any other instructions to become employed in the course of inspection and testing
Methods and frequency of inspections, testing and criteria of conformance
How can you amend or revise (or procedures) the ITP to suit the altering situations during the progress of the project?
How to conform to inspection check lists ready for every construction activity?

Who’s Responsible for ITP?

Typically the primary Contractor is accountable for preparation and implementation of ITP for any construction project. Preferably, the Contractor must ensure that his sub-contractors prepare the required inspection and testing strategy for the work activities and processes performed by them. Nevertheless, one ought to note that the general responsibility for ITP lies with all the principal contractor.

Actions Involved with verifying ITPs for a Construction Project/Contract

1.Study the contract documents and the technical specifications.
2.Prepare a list of queries related with missing data, any ambiguities or discrepancies associated with applicable requirements of supplies and workmanship.
3.Consult your customer or the clients representatives and make an effort to resolve the issues identified in item 2.
4.Identify the construction activities that require ITPs and checklists.
5.Identify the Hold and Witness Points as specified inside the contract document and by the client.
6.Evaluate the contract clauses that have considerable influence on top quality and workmanship specifications. Here, you’ll need to assess the consequence on the progress from the project owing to non-compliance or non-conformity of top quality on an activity. At this stage, it is crucial to include relevant data pertaining to tests, high quality standards when submitting ITP for Clients approval.
7.Finalize the checklists after reviewing it with all of the parties involved inside the relevant activities. The suggestions and also the inputs given by the knowledgeable staff (and lessons learned on previous/similar construction functions) are essential for identifying the problems that could cause costly rectification and delays.
8.Finalize the ITP in line using the conditions stipulated in contract documents. Similarly the ITP must basically complement the Top quality Management Program or Quality Management System (ISO9001) if already in location.
9.Timely submission of ITP for each and every earmarked activity to Client. If any clients observations and feedback have to be considered and amended the ITP accordingly
10.Ensure that proper awareness of the ITP among the personnel directly involved on each ITP. This means, proper training and awareness and involvement of workers from the beginning of preparation of ITP are a must.
11.Confirm the procedures required for reporting of Witness and Hold Points towards the relevant responsible individual.

Contents of ITP:

Preparation of ITP s should consider the following:

The actual nature and complexity from the work or the construction activity ;
Whether there’s access for inspection and testing;
What will be the resulting consequences in case of failure:- expense of remedial or rectification work involved, impact on the progress, accessibility and how easily rectification could possibly be carried out, any disruption to adjacent buildings or structures, progressive damage to other components of the construction, safety of workers or public and availability of sufficient resources.
The frequency of inspection and testing will have to become decided in accordance with all the circumstances of contract as well as the kind of inspection and testing necessary for the activity. In essence, certain inspection and testing will likely be carried out making use of appropriate frequency and sampling or statistical strategies. This entails selection of suitable representative sampling for huge operates. Sampling size and frequency might be increases or decreased according to the evidence on conformity throughout the progress of construction activities.
Record keeping or documentary evidence is essential to conform that the quality of completed activity or the product meets the specifications from the contract. Hence, the records could be in the type of checklists, test reports, certificates of compliance or conformity, approvals and survey and statistical information.
Reference to applicable specifications, codes of practices and standards. For example, reference ought to be created to: Contract document, construction drawings, design calculations, technical specifications or procedures, authorized samples, regulatory requirements, and Australian & International standards, manufacturers specifications, and acceptance criteria.
The necessary inspection and test procedures for the activity. In order to have consistent and reliable test results, the procedures for inspection and testing and recording have to be clearly defined inside the ITP. For example:- identification of test areas, the batch number, frequency of sampling, the method on which the samples to be taken, method of testing, the qualification of personnel involved in testing, correct calibration of equipment and measuring equipment, the documentation and recording have to become covered under ITP procedures.
Whether the top management from the contractor has appointed key quality and testing representatives to carry out the inspection and testing as required by the contract.
Whether adequate resources such as manpower, laboratories, field measuring and testing equipment are provided.
Whether the ITPs are updated regularly in order to accommodate changes on clients or project requirements. In essence, the validity from the ITPs in relation towards the current needs.
Whether the contractor has the procedures (or plan) in location to monitoring, measurement, and analysis necessary to conform that the work is carried according to required specification, workmanship and high quality.

The details provided above reveal that inspection and testing is a important factor on any construction contract that assures quality finish item.
