P6 Scheduling and Staffing Services

DRMcNatty helped a major transportation agency review, rebuild, and maintain efficient CPM scheduling techniques.


A client working on a portion of the California High Speed Rail project was looking for a consulting firm to rebuild their P6 schedule and provide ongoing support. This client was also looking to satisfy their diversity requirements for minority, disabled veterans and small business participation. This is a crucial portion of the project that includes over 40 miles of a new rail alignment consisting of at-grade, tunnels, and large viaduct installation.

A business development consultant from GCM reached out to DRMcNatty after learning that DRMcNatty could not only provide P6 consulting services, but that they are also CA Certified DVBE-SB. The fact that DRMcNatty is a California-certified DVBE allowed the client to meet the state’s requirements.
DRMcNatty was approved and the scheduling project was completed with ongoing support, maintenance and reporting on a weekly basis.


The client needed a CPM schedule with rigid, proven specifications that they could rely on to provide a realistic picture of the project and its resources. The client was relying on an overseas scheduler for work being done in the Antelope Valley and Santa Clarita,

which made communicating across different time zones challenging. Additionally, when major changes were requested, they had to be implemented within a strict time frame with consistent and cooperative effort between the project management team and scheduling consultants.


DRMcNatty identified areas of improvement and implemented more effective CPM scheduling practices. DRMcNatty worked closely with the client’s project management team to optimize preferred practices and introduce more effective means of communication. By utilizing simplified, proven methods of recording project information to meet dynamic deadline requirements, DRM paved the way for the client to maintain accurate CPM data.


DRMcNatty was able to identify improvements and quickly rebuild a more accurate CPM Schedule in a timely manner. DRMcNatty’s extensive experience with Primavera P6 helped make this transition smooth. As a result of this implementation, the client is able to track, report and forecast data more accurately to meet project milestones.
