Construction projects both large and small are frequently problematic in respect to ensuring that what has been contractually agreed between the client and the building contractor is actually delivered. All too frequently changes are made, materials substituted, short cuts taken and defects built into the construction. Construction monitoring provides clients with assurance that an experienced and independent professional is checking the construction site and making a detailed photographic record of both the quality of the work and also the progress being made on site. Whilst the construction monitor cannot directly intervene, unless permitted to do so under the construction contract, the record and comments enable the client to take up the issues with the contractor.
