Remediation work stopped at this site in 2008 when the previous developers went into liquidation. Integrale completed supplementary validation investigation and co-ordinated specialist groundwater remediation of the remnant hydrocarbon plume, design of new soils cover and hotspot clearance to help realise the full potential of this beautiful riverside location.
One of the largest renewable energy facilities (50 MW) in the UK, it has been in development since 2012; Intégrale completed the Geo Desk Study and Environmental Impact Statement in 2013. Being in an AONB, English Heritage objected, and planning was delayed until March 2015.
Intégrale rapidly completed the Ground Investigation and Remedial Method Statement by mid-summer allowing completion of the c. 90 acres of photovoltaic arrays by March 2016, generating enough power for 15,000+ homes.
At Intégrale, we take our professional responsibility and knowledge very seriously……. to the extent that we are willing to work…gratis…. for local action groups with valid concerns.
This quarry, located adjacent to Chew Valley Lake, has been a site of contention for six years, when permission was granted for asbestos disposal. Residents, supported by Intégrale, gained national attention through a series of high-profile appeals.
In 2013, the Planning Inspector ruled that the quarry could not be used as landfill for stable non-reactive hazardous waste; it posed a risk to residents and the reservoir. SSAG have monitored the quarry since and raised suspicions about the waste arriving. In late 2016, the Environment Agency suspended the permit for even controlled waste disposal .
Both University campuses pose inherent foundation difficulties, demonstrated by more than 20 specific projects completed by Intégrale. The University of Bristol dominates a hillside formed of interbedded sandstone and mudstone, with an unfavourable bedding dip! Stabilisation frequently requires shear-key piles and ground anchors.
The University of Bath, at the crest of a plateau overlooking an unstable hillside, suffers from cambered and gulled limestone. Site specific ground conditions often require plain slab/stiffened edge rafts, not needing a high degree of stiffness. Slab and beam/piled rafts can be appropriate at more artificial locations.
Assessing ground investigations, then optimising appropriate foundations for theme park rides and entertainment facilities with unusual static and dynamic spatial loading. Advising on extent of lime and cement stabilisation of largest WWII former armaments and ordnance storage complex, concurrent with UXO clearance operations.
Access to this elevated site is extremely difficult. Signs of superficial slippage in 2000, triggered boreholes investigation and slope analysis; could there be a catastrophic leakage of water? Should the site be abandoned and relocated? An older reservoir at a lower elevation had been demolished.
We concluded the reservoir was securely founded into Chalk. There was no significant risk of global instability, but the buried concrete structure could become locally exposed.
Reinvestigation in 2012 reached the same conclusion. A programme of localised stability works including ground improvement, soil nailing and drainage, was recommended.
Access to two new houses needed a road in a 3-4m cutting that truncated an old mudslide. Initial investigations by others had resulted in a tragic fatality with Health and Safety lessons for the complete ground engineering industry.
Intégrale’s boreholes revealed a complex Quaternary geology, defining ancient landslips and mudsliding. We completed parametric slope stability analyses and liased with a bored pile contractor to establish a technically and cost effective system of vertical, contiguous bored pile walling. Raking piles were included to resist horizontal loading and overturning.
