CRM has considerable expertise is designing underground drainage systems to BSEN752-4, working for a number of the North West's leading Structural practices as sub consultants. Working as a stand alone organisation, or as a virtual design office within a larger consultancy, CRM can offer a service stretching from simple pipe sizing checks, up to full design and detailing service.

We have experience of design with attenuation, foul drainage, flow to soakaways, pumped drainage, suspended drainage in basements and liaison/application to Water Utilities.

Whatever your drainage needs, CRM can tailor a service to suit

In addition to desk based design work, CRM offer a survey service, where we supervise a CCTV survey, collect invert and cover level data, and perform calculation checks on the system. This is often utilised on school sites, where limited data of existing infrastructure is available in the event of extensions/developments. By having qualified Engineers supervising survey works, it can be guaranteed that all the data is collected first time, often saving time and costly re-visits.
