Why work with FSi?

Do you need us to find the source of a leak in your 24-hour critical facility and come up with a plan to fix it? By tomorrow? We’ll be right over. Learn how the graveyard shift does its work – during their regular working hours – so we can upgrade the systems that support them? We’re there. Meet your organization’s strict design standards and security protocols? We look forward to it. Help you figure out the best process and solution to meet your ambitious project goals and limited budget? We’re happy to help! We do what it takes to meet your goals and make the project enjoyable for the project team along the way.
Our clients need their projects done on time. They have schools to open, airplane orders to fill, and patients to treat. We’re used to compressed schedules and tight deadlines. And we’re used to meeting them. That’s one of the reasons we have so many schedule-sensitive organizations – school districts, universities, and major manufacturing companies – among our repeat clients.
We’ve led hundreds of project teams and supported hundreds more as a subconsultant. This gives us good perspective on what it takes to be a good teammate, and we’ve incorporated it into how we work. We’re on top of deadlines and deliverables. We’re proactive about getting the information we need to get our work done thoroughly and on time. We listen, develop a thorough understanding of the project goals, and meet them with quality design and enthusiasm.
