HOW TO IDENTIFY VARIATIONS?
Variations do not mainly result from the direct instruction of a change by the Engineer. The key other issues that often result in variations are
Identification and resolution of a discrepancy/ inadequacy/ error in the Contract documents (Drawings, Specifications, etc).
In these days of reduced tender preparation times and lower consultant fees the Contract documents, and in particular, the design documents (drawings/specifications, etc), are unlikely to completely represent the project. In most cases, discrepancies/inadequacies/errors, etc in the Contract Documents will be notified to the Engineer. Thereafter it is common that the Engineer will try to protect the position of his documents/design by doing the following
In each case, the Engineer’s actions are likely to result in some kind of change to the Contract but the paper trail/project documentation is likely to be insufficient to support a variation claim.
Therefore in such cases, it is always the best strategy to get the Engineer to resolve the discrepancy/error / by correcting/completing the relevant part of the Contract document and issue to the Contractor which can be interpreted as a written instruction and sufficient to support a future variation claim.
The shop drawing process (preparation and review)
Most projects will include for the preparation and submission of shop drawings by the Contractor. This procedure is often misused by the Engineer, and with particular reference to variations the following often occurs
In each case, it is unlikely that the paper trail/project documentation will be sufficient to support a variation claim. Therefore in terms of protecting our variation entitlements during the shop drawing process, we should attempt to
The consequential effect of instructed variations on other parts of the Project
It is likely that most variations will have a consequential effect on other works, which could include
Accordingly, upon receipt of any variation and during its execution, its consequential effects should be checked to ensure that the full entitlements are realized.
The review of Method Statements and other technical submissions of the Contractor
Most Contracts will require the submission of method statements for the Contractor to describe the execution of the Works. As part of the review process, the Engineer may make changes to the planned execution which could result in changes/variations. Unless the changes were as a result of safety or other issues specified in the Contract the Engineer’s actions would result in variations to the Contract, without the issue of a formal variation instruction.
Accordingly, all comments and requests for change of any method statement or other technical submission should be carefully compared with the Contract and where changes exist the Engineer should be requested to instruct the changes before any resubmission of the Contractor’s document is made.
The review and rejection of Subcontractors
Most Contracts will provide for the approval of all subcontractors and in many cases, the Engineer will reject the Contractor’s proposal and either formally or informally suggest an alternative. If the Engineer’s grounds for the rejection are insufficient or not provided when requested the action could give rise to a Variation claim, particularly since the use of another Subcontractor is most likely to involve the incurrence of additional costs.
Therefore, in order to effectively manage the identification of variation orders, it is recommended that the following procedures and practices are implemented
