P1 Group delivers consistent, high-quality fabricated assemblies that enable clients to meet even the most demanding construction schedules. At its plumbing fabrication shops in Lawrence and Lenexa, P1 uses state-of-the-art tools, equipment and procedures.
All of P1’s project fabrication is detailed, planned and executed by project managers, jobsite foremen, the Auto-CAD detailing department, and fabrication shop foremen. The collaboration between the shop and the jobsite gives P1 Group the ability to manufacture and deliver complete plumbing assemblies during the early stages of a project.
P1 Group has dedicated its resources to providing a safe, climate-controlled work environment. This enables the organization to improve the productivity of assembling the components, significantly reducing installation time and costs. P1’s preplanning and fabrication can decrease field man hours by as much as 30%.

Each assembly is preplanned and staged so that delivery can be coordinated with on-site contractors.

Prescheduled production time results in on-time deliveries, fewer man hours and decreased production time. All plumbing is produced to match the individual project plans and design specifications.
