Record keeping


[edit] Introduction

Appropriate records should be compiled and maintained throughout the duration of construction projects. This creates a contemporaneous history of what happened at what point during the course of the project that can be referred to if necessary.

This not only establishes a ‘memory’ or ‘paper trail’ for the project through which activities and decisions can be reviewed, it allows for the reconstruction, review and analysis of events and timelines should a dispute arise. Disputes are often determined by the available records, rather than by the facts, and so it is commercially very important to the parties involved that good records are kept.

There are a number of reasons for record keeping:

The extent of the record keeping required will depend on the type of project. A balance must be maintained between keeping adequate records in preparation for a dispute arising, and attempting to record everything, which is can be difficult, time consuming and costly.

Some record-keeping requirements, such as recording the minutes of meetings for example, may be carried out at the discretion of the individual organisation, with different frequency rates, levels of detail, and time for which records must be kept, appropriate for different situations. Other records may be a legal or contractual requirement, following prescribed rules.

For example, under the Construction Industry Scheme (CIS), contractors must keep a record of the gross amount of each payment invoiced by subcontractors, excluding VAT and any deductions made from subcontractor payments. These details must be kept for at least 3 years after the end of the tax year they relate to.

Ultimately, when the completed building is handed over to the client, a set of record information should be passed to them so they are able to operate the building.

It is important that the standard of records kept is high, or they may not provide the expected information when they are actually required. In particular, records should be dated (including incoming records) and where appropriate, signed, and a document management system should be in place to allow efficient storage and retrieval.

Information is now generally managed using specialist software, and apps that make the preparation of records easier and more reliable are also available. This can, for example allow records to be made on site using a mobile phone, which are then automatically uploaded to a project document management system.

Increasingly, project information is prepared in the form of a building information model (BIM), and this may include project records as well as design and specification information. An as-built or as-constructed building information model might be prepared on completion of construction works, consisting of documentation, non- graphical information and graphical information defining the delivered project.

During operation, this might be described as an Asset Information Model (AIM), that is, a model that provides all the data and information related to, or required for the operation of the completed built asset.
