Scheduling Capabilities

Oil Rig at NightPSI utilizes Oracle’s Primavera (P6) and Microsoft Project for project scheduling and tracking purposes. We have a full time scheduling team that assists project managers in determining available resources and developing a workable project schedule. When a task order is received, PSI will develop a specific schedule to match the needs of that project.

The general project schedule will follow the template listed below:

  • Kick-Off Meeting
  • Project Schedule
  • Initial Design Considerations
  • Long Lead Item Identifications (i.e. permits, directional drilling, materials)
  • Environmental Studies
  • Centerline Survey
  • Issue For Review (IFR) Drawings Package
    (60% Design Milestone)
  • Issue for Bid (IFB) Drawings Package
    (90% Design Milestone)
  • Procurement
  • Issue for Construction (IFC) Drawings Package
    (100% Design Milestone)
  • Construction Kick-Off
  • Inspection Services
  • Substantial Completion and Close-out Documents
  • Record Drawing Package

PSI is experienced in tracking and reporting progress to overall work completion. PSI implements each specific client’s tracking and reporting process. If a client does not have a system in place, PSI works with the client to develop a system that works effectively for both the client and the specific project.

PSI constructs project schedules for clients from the “ground up”

PSI will initially assist by providing a high level schedule early in the project development.  The high level schedule focuses on critical path items which typically consist of permitting and long lead item design and procurement.  Once the initial critical path is identified the remainder of the schedule is developed and refined accordingly.  After the project progresses past the development phase then a detailed, resource loaded schedule is provided.

PSI provides timely progress reports based on a detailed project schedule.

We provide information on potential impediments such as issues with contractors or survey companies. We include milestones suggested by the client for measurement purposes to enable determination of project deliverable date changes.

PSI can build construction schedules for clients who do not maintain an in-house scheduling team.

This helps clients hold contractors to agreed schedules and identify possible date changes before they become problematic. Building “what-if” schedules can ensure projects are finished successfully and on time.

PSI manages in-house schedules for all active projects.

This allows us to manage resource allocation as well as ensure that our employee’s time and skills are maximized.
