‘Working with Optimal Fire has been a pleasure for Safari, Optimal recently completed service penetration passive fire works and additional passive fire support to the entire project to a high standard with impressive and substantial QA. Optimal Fire worked well alongside Safari and weren’t afraid to apply extra resource and efforts to progress our development. Would recommend and look forward to working together again.

“Optimal Fire’s professional and dependable approach was a great asset to have on site. Especially with the upgrade of an existing building where the passive fire design doesn’t always work out as planned. I’m looking forward to working with Ray’s team in the future”
