Delegates attending the recent Royal Institution of Chartered Surveyors (RICS) ‘Surveys in Practice Roadshow’ have been advised to contact the NADC with regard to seeking further investigation on underground drainage problems.
When a surveyor is completing a house purchase survey they might recommend a CCTV investigation of the drains to ascertain any damage that could affect the structural integrity of the building or may lead to remedial/repair costs to the drainage system. This would normally involve subcontracting the work to a specialist drainage contractor who would provide a report based on a visual inspection using CCTV cameras and possibly a water or air test. This information would be compiled with other survey data and passed to the customer, often with estimates on remedial options.
In the past there was no standard employed for domestic drainage investigation and reports could be in any format. Historically there has been no certification system to prove adherence to any form of standard meaning that surveyors were reliant on the unmeasured and subjective experience of the contractor. In effect you had a qualified surveyor using information from an unqualified drainage operative. The potential for disaster is obvious.
Things have changed for the better. Now a surveyor, an engineer, a housing officer, an environmental officer can choose a CCTV drainage surveyor with an objective qualification that was produced by the Water Research Centre in association with Environment Agency and the National Association of Drainage Contractors. Training is delivered by experienced and qualified personnel, complies with MSCC5 (BS EN 13508-2:2003+A1:2011) and the qualification is an EU Skill.
This ties in well with Viewline’s CCTV reporting software which also fully complies with the standard and is easily understood by the the client.
