A multidisciplinary engineering practice in Miranda de Ebro (Burgos) with a distinct fire-protection division alongside industrial and civil work. Its fire practice produces PCI project design and documentation — hydraulic and flow-pressure calculations, active and passive protection design (detection, sprinklers, hydrants, compartmentation, fireproofing), regulatory legalisation and site supervision — oriented to CTE DB-SI and RSCIEI compliance rather than physical installation. Its outputs are an aid to professional engineering judgement, not a substitute for it.
