Project:  Alea Casino SI, Glasgow

Value:  £40,000

Timescale:  2 weeks

Following the reopening of sites in Scotland, ERS was appointed to undertake a site investigation at the Alea Casino on Springfield Quay. In addition to the H&S challenges posed by the Pandemic and security issues due to the casino being operational late at night, the tight site area was also underlain by several utility pipes.

The scope of work  comprised of 2 cable percussive boreholes to rockhead with rotary follow on to obtain rock core, 3 Cone penetration tests (CPT) to refusal and 2 trial trenches to determine the position of underground utilities. Samples were collected for the purpose of geotechnical and geo-environmental testing. Gas and groundwater monitoring pipes were installed at various exploratory locations for water sampling and gas/ground water levels to be monitored.  

 

Several challenges were faced whilst undertaking this project. In addition to adhering to newly introduced COVID-19 guidelines such as distancing and sanitising, the site was located directly in front of a casino which was open to the public until 4am. Therefore, great care was required to maintain a safe, secure and clean working area that would not present a risk to the public and disturb the day-to-day business of the casino.  

 

The tidal effects of the nearby River Clyde meant that advancing the boreholes was a challenge due to underlying sands and silts ‘running’ up into the borehole at times. Furthermore, the area of ground on which the investigation was carried out was very small, with obstacles such as overhead restrictions, underground utility cables and areas of soft ground. This meant that we had ‘one shot’ at each exploratory location to obtain the clients objectives. Plus, as several different operations were ongoing at the same time, careful planning had to be made to ensure all personnel and plant were operating within a safe working distance of each other.

 

A COVID-19 scare to a member of the drilling team temporarily halted site work until test results proved negative. This added to the difficult drilling conditions meant the site works over ran the anticipated completion date, but a quick turnaround with lab testing, monitoring and reporting allowed the project to be completed on time. There were no other health and safety issues.
