We're back onsite to carry out constant head test to determine the infiltration rate in to a band of gravel #SUDs #ergointhefield #siteworks #drainage

Trial trenching is used to locate old mine shafts. There is a degree of uncertainty in all historic shaft locations so sometimes they aren't where they're shown on maps. We're on site in Co.Durham trying to identify whether a shaft encroaches the boundary #siteworks #mining

At sensitive sites it's always important to liase with the site owner to work out the best approach; be it time constraints or working around certain locations. #siteworks #development #fore!

Another #brownfield site being redeveloped in North Tyneside. We're doing mini rig work to take environmental samples and provide Geotechnical input. #seaview #siteworks #windowsampler

Jonny is down in Mexborough today at the Gas Protection Verification Course put on by CL:AIRE. He's with other consultants, installers and Regulators learning about the theory behind the installation and #verification process inc. testing procedures #cpd #development #learn

Practical time at the CL:AIRE Gas Verification Course. We're having a look at installation methods in action. Showing good and bad practices with #taping and #welding. Thanks to DMI Ltd for showing us the ropes and letting us have a go! #practicemakesperfect #cpd #learn

We're investigating the presence of potential contamination from historic ASTs today. They just happened to be under this large demolition stockpile. #firstjobfirst #wholeftthishere #siteworks #ergointhefield

We're onsite in N.Yorks investigating ground conditions beneath an existing structure. Thick concrete, tight access and poor ventilation are the main constraints today. #ergointhefield #siteworks #allthecoring #windowsampler #minirigs

Not a cloud in the sky today. Our engineer was out in Northumberland validating gas membranes this afternoon, needless to say he wasn't keen to head back to the office. #validationworks #ergointhefield #gasvalidation #planning

Gas Monitoring is an important part of many planning consents. Used to identify risks from gases which arise from site usage, natural deposits & subterranean workings. Results are screened against CIRIA guidance to assess potential risks. #siteinvestigation #nhbc #ergo

We're on site, investigating the extent of ash fill encroaching a housing development. The fill arising from an infilled river valley was missed during the initial site assessment carried out by others and was discovered during foundation excavations. #duediligence #siteworks

It's all coming together now on our first day on site in #Washington, Tyne and Wear. Our engineers are working hard to make a good start for the next fortnight of works. #ergointhefield #groundinvestigation #minirigs

Looks like it's another good site day here in #Tyneandwear. We're back to carry out the #rotaryinvestigation to look for evidence of any mine workings #ergointhefield #siteinvestigation

Onsite in County Durham this week, first job is creating access for #cablepercussive and #rotarydrilling rigs across a significantly sloping site #workinprogress #ergointhefield

We're onsite in Cumbria investigating rock conditions for a new retaining wall to be installed. #ergointhefield #siteworks #rotaryinvestigation #rocklogging #rotarycore

We've been in Sunderland the last 2 days. Carrying out #cbrplateload tests around an 11 storey building. We had to liaise with the council to ensure footpath closures were in place and carried out a comprehensive H&S plan to minimise potential risks to the public #healthandsafety

Thanks to Wood and @EAnalystUK for hosting an interesting lunchtime session on 'Consistency & Robustness in the Appraisal & Management of Brownfield Land' #

We are delighted to be onsite in Southern Scotland completing a 12week programme of geotechnical enabling works validation via Plate Load Testing and Non-Nuclear Density Gauge testing for a valued client #ergoonsite #geotechnics #siteworks

We've been out on site in County Durham today beginning work on a new project, part of which involves the probing of the adit we found hiding in the undergrowth today! #ergoonsite #coalmining #siteworks #whatsintheground

We're back down on site in Teeside completing a site investigation with several deep boreholes to do. We hope it continues like this for the duration. #siteworks #ergoonsite #cablepercussive
