Thames Water Sewer Connection Via Timber Heading – North London

Client: Education Sector - Buxton School London Duration: 2 Weeks Value: £15k - £20k

SB Civils were engaged as a civil engineering contractor with a specialty in timber headings to carry out a shaft excavation, timber heading, tunneling & manhole construction to connect a school in north London to the thames water sewer in the highway.

Works involved included the excavation to allow access to the sewer, the spoil was removed and stored safely for a later disposal to a registered tip, a frame of timber was installed to form the entrance of the heading, all the heading timber is treated, new and free from cracks and faults. The excavation was by hand using hand held compressed air driven spades and picks, a further heading frame was installed to support the timber boarding. As the excavation of the heading proceeds towards the thames water sewer, rails were laid on the floor of the heading, Using this method the heading continued installing frames and boards until the Thames Water Utilities sewer was reached. Then the manhole construction commenced.

All works were completed to a very high standard, inspected regularly by Thames Water inspectors and signed off with no snagging. Works were completed on programme and to budget with no incidents, accidents or complaints.
