DGA

We are now celebrating our 21st Birthday and I reflect that, having started as a one-man-band to carry out work for the Security Forces in Northern Ireland, we have grown into a firm with sixteen members of staff, turning over more than a million pounds each year. Our current business plan is focussed on passing control and ownership of the firm to a new generation: we are leaders in our field and are developing new capabilities to maintain this lead: some of the new developments are noted below.

Please join us in our celebrations,David Goode

21 Years of Specialist Engineering

Scottish ParliamentWe were proud to have been asked, in 2010, to assist with the design of a new entrance security building for the Scottish Parliament at Holyrood. We had previously completed a large hostile vehicle mitigation scheme around the site and the new work proved to be a technical challenge, coupled with the added requirements for working on such an iconic site. The finished building sets a high architectural standard and improves the experience for visitors to the building.

Water Industry SecurityAs a company with RSES members we have been working on a number of water industry security upgrade projects providing design solutions for the protection of boreholes, toxic gas storage and reservoirs. The work includes assessing the site vulnerabilities and providing design solutions for physical security, electronic security and hostile vehicle mitigation, to enable the water authorities to comply with the requirements set out by the water industry regulator.

Training RangesOne of our early projects was the design of a building for explosives method of entry training and we have recently led on a project for an updated version of this, using larger charges. We have also recently completed the designs for a number of small arms and tactical training ranges, both indoor and outdoor which feature both conventional and advanced interactive targetry.

Enhanced AnalysisWe have carried out finite element and finite difference analysis since our inception but have recently upgraded our capability with new staff and high performance hardware. This has been in response to the need for a capability to work on more complex blast problems (using Euler-Lagrange coupled systems) and in-structure shock assessments for deeply-buried facilities.

Ballistic testingWe have been a UKAS-Accredited test house (for ballistic effects on glazing materials and doors, windows and shutters) for some time, but have felt that we should be looking at a capability to fire faster and heavier rounds and fragment simulating projectiles. We purchased a number of Bofors 40mm components last year and are now building a flexible platform for firing a range of calibres from 0.50” Browning to 40mm (Bofors 40/60). This will be commissioned early in the new year.

Grenade Range During 2014, we were asked to carry out calibration tests on surrogate explosive devices representing grenades and anti-personnel weapons. With a view to carrying out this work in Suffolk, and also another project regarding improvised devices, we constructed a partially-buried range for small charges (up to 200 grams of TNT) which would contain the hazardous fragments generated by the detonation and limit the noise generated. We look forward to using this small building for testing other close-in weapons. We have also developed the capability of conducting in-house petrochemical deflagration tests in collaboration with BRE.
