Quantum have been awarded another Reservoir scheme under the Central Alliance Delivery Framework for Dwr Cymru Welsh Water. Alliance Partner, Mott MacDonald Bentley (MMB) awarded Quantum the prelim geophysical survey phase as prelude to a possible future intrusive ground investigation. This Phase 1 survey will target the shoulders of the dam and lands immediately adjacent the spillway at Cantref Reservoir, just north of Merthyr. Using Ground Conductivity (Electro Magnetic) and Resistivity Tomography surveying techniques the aim is to identify potential areas for future remediation and strengthening.
Quantum began work on a bridge replacement scheme on behalf of CORMAC Solutions in December 2017. The scheme includes the demolition of an existing concrete barrel arch bridge and construction of a new structure supported by 26 No 273mm diameter cased piles. Piling, demolition and construction will be carried out in house by our specialist teams with works scheduled for completion in May 2018.
In December Quantum was approached by City & County of Swansea following an initial ground investigation in August 2017, to discuss engineering options to deal with flooding along the cycleway located off Tae Road, Peniel Green in Llansamlet. Following short periods of rainfall the area rapidly floods. Quantum designed and installed borehole soakaways to depths in excess of 25m and installed drain access chambers connecting the ditch drains to the boreholes. The scheme proved successful, providing a potential significant cost-saving and making the cycleway available to the public.
Quantum have been awarded the Ground Investigation for A52 &A43.A45 Trunk Road Sites under Area 7 for Highways England. Works include cable percussive, rotary drilling, window sampling and TRL DCPs at various locations along the route. The £25,000 scheme will also include soil vacuum excavation to locate and expose existing buried utilities provided by Quantum.
Quantum have recently completed a ground improvement scheme at Beaufort Avenue, Swansea. A domestic building had suffered settlement and Quantum were awarded the contract to stabilise the ground beneath the property by injecting grout into the underlying soils from ground level down to bedrock at around 7.0m depth. The grout was injected via Ischebeck TITAN hollow micropile bar installed using a specially adapted short stroke drilling mast enabling the works to be carried out from within an existing ground floor room with minimal disruption.
Works at Durleigh Water Treatment Works are now complete undertaken by Quantum’s South West Regional Office on behalf of Wessex Water Services Ltd under the existing Geotechnical Framework. The £43,000 Ground Investigation included cable percussive and rotary cored boreholes including a PAS128 utility survey.
Quantum return to Mountain Ash to commence the next phase of the ground investigation works for the proposed Cross Valley New Link Road. Having undertaken the two previous ground investigations for the Local Authority, Quantum were awarded the next phase by the confirmed Principal Contractor constructing the new link, Walters (K) Ltd with Scheme Designers, Ramboll UK Ltd, also on board.
Our excellent and thriving relationship with Skanska Construction (UK) Ltd, continues with the award of two new reservoir ground investigations; Crai Reservoir near Sennybridge and Craig-Y-Pistyll Reservoir near Aberystwyth. Both schemes present challenging access and environment constraints with a variety of intrusive investigation methods to be utilised. Works are anticipated to commence late November, early December.
Quantum’s South Wales Geotechnical Dept successfully complete ground investigation for proposed upgrade of existing primary school at Five Roads, Llanelli on behalf of Carmarthenshire County Council. Opus International (UK) Ltd were the Project Engineers. The works included window sampling, dynamic probing, machine excavated trial pits and a variety of in-situ testing, all undertaken using Quantum in-house plant, equipment and laboratory services.
A warm welcome to our newest team member, Daniel John, who joins the South Wales Geotechnical Department. Working out of our Bynea Head Office, Dan joins the team as an Engineering Geologist, having previously worked for Geotechnical Engineering Ltd. Dan brings with him several years’ experience managing a variety of ground investigation schemes across the UK with his most recent role that of commercial manager in his previous employment. With his enthusiastic and friendly demeanour, coupled with his technical and commercial abilities, we are confident that Dan will flourish in. View Article
