In new construction, MAREK is able to coordinate with MEP trade partners to provide a comprehensive penetration and joint firestop package, using single source manufactured products as is often required per project specifications. On existing buildings, MAREK can provide an extensive survey of the life safety drawings in conjunction with an inspection of the plenum space at fire rated walls, to identify any deficiencies. This is followed by a formal proposal that includes a plan of action to bring rated barriers up to code, cost projection, access plans, and schedule duration.
