Terrier - Restricted Access
Terrier – Restricted Access

The combination of restricted head room and a ‘confined space’ presents major obstacles to any site investigation. However, our Terrier rig was able to gain access and complete a  geo-environmental investigation in such a space. Its quite amazing where this little rig can get.
Access was through a standard doorway working with an overhead ceiling clearance of
less than 30mm with the machine set up. Precision operation was required to ensure we completed five boreholes, each to 6 metres in depth, with SPTs every metre, all in a safe and efficient manner.
The nature of the confined space meant that exhaust gases from the Terrier’s engine had to be vented to an outside area. We used an extendable sectional exhaust pipe to ensure a safe working environment. But just in case we also carried out carbon monoxide monitoring to ensure our crew’s safety.
Even better, our work was completed without the need to close the car repair workshop we were working in. allowing our client to continue panel bashing, filling and spraying to his hearts content.

Machu Pichu

alma roadOK so not exactly Peru, but a very steep, terraced site in the Chilterns.

The extremely tight access didn’t prevent our site team from getting in and completing a comprehensive geotechnical investigation, including soil sampling and dynamic probing to 10m depth. The work was completed on time and on budget, with dynamic probing data issued to the client on a ‘same day’ basis to assist with pile design.

Subadra Complete New Fuel Storage Facility For Millenium Seedbank

This month saw us complete construction of a new fuel storage facility for Royal Botanic Gardens’ Millenium Seed Bank. A key aspect of the project was to ensure that the Seed bank was continuously supplied with fuel (used for heating greenhouses) as any protracted outage would have had dire consequences for the seeds. In the event the switchover was completed without a hitch.

Subadra were responsible for all the civils works (constructing the tank base and retaining walls, installing a dedicated drainage and spill capture system, electrical installation etc. Our partner, Vectec, were responsible for supplying and installing the tanks and associated pipework.

Listed Georgian Vault Reconstructed

Subadra have completed the reconstruction of a Grade II Listed coal vault in Marylebone, London. The vault, which supported the pavement above, had partially collapsed and was unsafe. Working from pavement level, we removed the damaged masonry and replaced it with an enlarged reinforced concrete structure, turning what had been an unuseable space into a fully serviced utility room for the client. We carried out the Planning and Listed Building applications, foundation and structural design, as well as all demolition and construction work.
