Hallen has completed many successful projects that involved all phases of construction. The scope of these projects was challenging and diversified. Many of these projects were located in facilities where daily operations continued while construction was ongoing. We have put together a team of sub contractors that can remediate a hazmat site, drive piles, pour pile caps and foundations, install subsurface piping systems, erect structural steel, set pre-fabricated buildings, and install mechanical systems and electrical components. This group has completed many projects with very tight schedules on time without sacrificing safety or quality.
