Value Engineering from JDP helps self-builder gain planning permission

  • 30 Jan 2019

Expert knowledge and advice from JDP‘s unique Technical Support team has helped a client complete a self-build project.

The project saw JDP’s Technical Support team specify expert drainage scheme for the property in Brampton, Cumbria, resulting in significant cost and labour savings.

The JDP team worked closely with the client, John Coulthard, to initially provide a drainage take-off.

After reviewing the existing drainage layout and calculations, it was agreed that to provide a more cost effective and efficient SUDS solution, a new drainage scheme would be proposed to meet planning stipulations.

Using its industry standard Micro Drainage software and new accurate ground percolation test results, the JDP Technical team were able to take the data and re-calculate the dimensions for a more suitable cellular soakaway tank.

With limited space available on site, the soakaway tank was designed with extra storage to incorporate the STP (sewage treatment plant) effluent to combine and soak away with the stormwater.

The calculations provided by the JDP Technical team were enough to gain the necessary specialist planning approvals the client sought, allowing drainage works to begin on site.

As well as in-depth technical advice the team were able to offer, a value engineered re-design of the drainage system which reduced the number of products used, in turn reducing expenditure and labour time.

The Technical Support department incorporated a range of JDP’s key products into their surface and foul water design including a total of 228 metres of ULTRA3 pipework; PPIC inspection chambers; channel drain and silt traps.

JDP’s RAINBOX 3S® crates were identified as the ideal product to provide the soakaway system servicing this site.

The RAINBOX 3S® system offers real benefits for a project of this size due to the ease of installation and the reduced installation time on site compared to traditional methods.

The client was impressed with the knowledge and services provided by Technical support and the JDP sales and delivery teams, commenting: “Gary (Armstrong, JDP’s Technical Support Technician) and the team at JDP have been great. The Technical Support team were really helpful in identifying any potential issues and finding the right solutions.”

Gary commented: “We proposed the drainage re-design to the client based on previous knowledge of what is expected when trying to gain planning approval for a self-build project.

“John was willing to trust our knowledge on the planning process and on which products would be acceptable, which made for a quick turnaround from design to installation and he reaped the benefits of reduced project time and costs.”

JDP’s technical support services are available to JDP account customers, for big projects or small, free of charge.
