News: Rise to the Occasion
More new clients for HB Tunnelling, we where contacted to assist with 3 number new installations as the client was confused with what others where offering.
Upon undertaking a site visit it was established that the client was looking for a full turn key contractor to undertake 3 no installations.
The works comprised of :-
1 x 150mm diameter foul rising main from a cofferdam to an existing manhole.
1 x 125mm diameter storm rising main from a cofferdam to an existing manhole.
1 x 150mm ID cable duct
Upon accessing the site & HBT considered all techniques & opted to:-
Install 150mm 125mm diameter rising main from Cofferdam to existing manholes via guided augerboring technique as a steel sleeve could be utilised as the sleeve pipe to the existing manhole & then the MDPE pipe could be butt fused & slip lined with in the steel sleeve annulus grouted.
This would be the best solution as the existing manholes where 900mm in diameter.
The 150mm electric duct could be installed using the HDD technique as this was over 50mtrs in length & would be the most cost efficient option for the client.
Ground was a good Firm Clay, so order received & off to work we went
We do not steer the client down a path to suit our technique only, we fully advise them of the risks attached to each technique available to them & then we advise on a suitable solution to fit there budget with associated risks.
With our no nonsense approach to works we assisted the client to be able to make the correct decision on which technique is most suitable, The client loved our honesty with them & with that we was awarded the contract.
