I need to have a new bunded plastic oil tank installed, and will be engaging an OFTEC engineer to install the pipework etc. To keep down costs, I'm planning on building the piers and the platform myself. I have consulted the OFTEC advice/regs: https://www.commercialfuelsolutions.co.uk/downloads/oftec/T19_base_construction.pdf
but one or two details elude me.
1. Would it be sufficient to build two piers or would I need three?
2. I'm thinking concrete blocks laid flat with concrete lintels spaced to support paving slabs to achieve the required width ie one back and front, and one running down the centre to support the inside edges of the slabs. Or should I be planning on a platform made entirely of lintels laid adjacent to each other?
The new oil tank will be located next to the existing redundant steel tanks, on the same concrete base on which the existing piers and tanks have been built.
(And before anyone suggests that I remove the old tanks and utilise their brick piers, this isn't possible because the regs have changed since they were built, in respect of the distance required from a boundary wall. Also it will be virtually impossible to remove the steel tanks from the location, so I'm leaving them in situ for the time being)
