Project description
As part of a due diligence programme, our client was concerned that an existing warehouse under consideration for rental may be affected by ground gas issues. The site was built on brownfield land and site investigations external to the building identified elevated ground gas.
A series of VaporPin® installations were installed within the building to allow sub-slab monitoring to take place. Due to timescales and the level of assurance required, a period of continuous monitoring was carried out at selected locations to identify if any further action was necessary.
GGS deployed a number of AirSentinel monitoring instruments to the site. These are self-contained battery powered units that can measure a series of gases and record the data.
Outcome
Monitoring data was supplied to our client at bi-weekly intervals to allow faster decision making. Following several weeks of monitoring a number of significant weather pressure systems were captured, allowing for the collection of high-quality data to inform the risk assessment.
The data was presented to the client in clear time series graphs within our GGS DataPack® report along with associated periodic monitoring data, observations and calibration certificates. This in-depth information, communicated in a clear and understandable format, allowed the client to understand the ground gas regime and have confidence that the correct safety measures were in place.
