Three unexploded WWII bombs found in Cologne and 20,000+ evacuated. If you are working near historic bomb zones, #UXO is not just history – it is a hazard. We have looked into the WWII bombing history of Cologne and the devastation that was caused – 1stlinedefence.co.uk/news/unexplode…
☀️Great weather and great progress in Luton! The #1ldteam is supporting UXO Borehole work to keep a geotechnical project safe and on track. No UXO finds so far! Shoutout to Andy and the team, stay safe and keep up the good work 💪 #uxo #risk #mitigation #investigation #clearance
Today marks 80 years since VE Day. It is a poignant day for many reasons, and we are marking the occasion to honour the sacrifices made to bring peace to our nation. We hope that you have a fantastic day of celebrations. Image © English Heritage #VEDay80 #VictoryInEuropeDay
The #1ldteam received a visit from a random visitor this week. It is not every day you get to see a magnificent bird of prey this close however, they are used on construction sites more often than you would think. Thank you Aaron for submitting the images. #uxo #risk #mitigation
We would like to wish our clients, suppliers and staff a relaxing Easter bank holiday weekend. A quick reminder that our office will be closed on Friday 18th April and Monday 21st April, and reopens Tuesday 22nd April. #uxo #risk #mitigation #investigation #detection #clearance
The #1ldteam have been working in #Southampton to support our client on a development for High Voltage cable ducts. The section being supported was recorded as sustaining 17 bomb strikes. Fortunately, nothing #UXO-related has been discovered to date – we will keep you updated.
The #1ldteam have been supporting a client at the Royal Arsenal in Woolwich. It is not uncommon to find interesting artefacts due to the rich history of the site, and last week our operative discovered a 6-inch stone cannonball, which an archaeologist on-site dated to the 1450's.
A week on from the discovery of a British WWII-era 1,000lb unexploded bomb on a construction site in the Saint-Denis area of Paris, 1st Line Defence investigate the bombing history of the incident area. Read more: 1stlinedefence.co.uk/news/unexplode…
Suspected Unexploded Bomb found in a residential garden in Dartford, Kent. This bomb find is another example that #uxo can be found in some unusual places – and not always where it was originally targeted – and we will be keeping a close eye on how the disposal operation unfolds.
1LD operatives were dispatched to the Isle of Wight this week to provide UXO Watching Brief support for our client, and during routine operations we discovered a ‘live’ 2-inch mortar. Read more 👉 bit.ly/3Diyzyf #uxo #risk #mitigation #investigation #detection #disposal
@1stLineDefence have recently finished an over-water Intrusive UXO Survey for our client in East London, which involved mobilising a 1.5 ton Rig on to a pontoon by crane to carry out UXO Clearance. Need to get your project assessed for UXO risk? Visit: 1stlinedefence.co.uk
We have completed a project which at first glance, did not appear to have any UXO risk – until evidence that the site had been targeted in an Incendiary bombing raid was found. We surveyed the site, 19 x 1kg Incendiary bombs were found/disposed. Read more: bit.ly/418GLsC
The @1ldteam have been busy on a site in London where the developer found a 6-inch unexploded projectile in made ground. As we were investigating, we also found another projectile & a 3-inch mortar. All items were disposed but where the fill material came from remains a mystery!
Wishing our clients, staff & suppliers a Merry Christmas & a Happy New Year. Our office is closed from Weds 25th Dec & will reopen on Thurs 2nd Jan 2025. If you need support whilst the office is closed, email: [email protected] and someone from the team will get in touch.
The @1stLineDefence rigs have been busy working in the winter sun in East London this week. The project has involved multiple site visits to survey and provide #UXO #clearance. Thank you to all of the #1ldteam who have worked round the clock to keep this project on schedule.
@1stLineDefence have been assisting one of the UK’s leading energy providers to mitigate the risk of #UXO for the UK’s largest solar farm. The project has utilised multiple services & we are now completing the final stage of target investigation so that groundworks can commence.
