Case Studies

Oxford Brookes Student Housing

Contractor SSC Construction, overseeing the 885-room student housing development of a former army barracks for Oxford Brookes University, already had a foul and surface water drainage system planned for the site until they took advantage of JDP's Technical Support team, who value engineered the plans, and discovered using ULTRA3 saved 35% on total system install cost when compared to traditional materials.

110 - 630mm products not only saved time and cost but the impermeable area of the site was reduced from 1.6 to 1.2 hectares, lowering the risk of localised flooding and pressure on flood management systems.

John Smith, site manager for SSC Construction, praised ULTRA3's versatility and ease of installation as a single product system: "The fittings have an integral seal which speeds up installation and reduces air-test failure rates, and the smooth wall pipe makes it easy to handle on site even on the larger diameter sizes.

"It's the direct connections to the inspection chambers that really quickens things up. We were putting the system together in hours rather than days."

Inverurie Community Campus

Due to open in 2020 the multi-purpose Inverurie Community Campus, near Aberdeen, will provide space for 1,600 pupils and features a range of amenities for the wider community. It is one of the largest school construction projects undertaken in Scotland.

Originally planned to utilise another range of EN 13476 system, contractor David Smith looked to JDP to supply them with a complete range of underground drainage products — a decision which resulted in a 20% cost saving for this stage of the project.

The combination of ULTRA3's flexibility and local stock availability helped overcome on-site challenges as construction progressed as all products were supplied directly from the local JDP branch.

Caroline Davidson, JDP Regional Sales Office Supervisor, explains: "JDP focuses on providing exceptional service and specialist support to the industry and this project was no different. Space on site was a huge issue for David Smith, and having the option of calling off stock from the local branch added peace of mind and increased efficiency.

"The contractor has two drainage squads and both contacted us separately to say how easy it was to install and comment on how robust ULTRA3 is."
