The company wanted to enhance oversight of contractors on large capital projects to promote efficient and safety project completion.

The objective was to implement a partnered approach for safety oversight resulting in highly successful utility construction and/or maintenance projects.- For this project to be a success we have to work as a Team keeping Safety in the

forefront of what we do and each individual being a champion for Safety.

The Brazos Valley Connection, a 58.7 mile electric transmission line that runs from Harris County to Grimes County, will help address much needed future infrastructure improvements while meeting an obligation to provide safe and reliable power.

CenterPoint Energy partnered with a company we were familiar with

The company had specialized in Human Performance Improvement with utilities

Contractor oversite was a new offering

Their experience in and knowledge of utility services made them a great partner

The New Approach

7

Oversee daily work throughout the project and document safety and health observations

Compile an overview summary report of findings and submit report to the CenterPoint Energy Safety Department by Wednesday of each week

Call a stop to work, action or behavior generating an imminent danger situation

Address the condition along with the responsible CNP Contractor Coordinator

Report other safety and health issues related to safe behavior, compliance violation, work hazards or bad safety practice to the CNP Contractor Coordinator

Our Expectations for the Contractor

8

Include a recommended corrective action for each observation and finding identified and reported

Assimilate and conduct periodic safety and health communication meetings with the Safety Representatives of all contractors on the project

Maintain a daily log of areas, actions and locations where observations were focused

Our Expectations for the Contractor

9

Tailboard created to be used by contractors on the project

Some contractors were not covered by 1910.269, but they used the Tailboard document to support the safety culture

This was an auditable element during safety observations

Standardize Project Tailboard

10

This scorecard was created to document safety performance on the project

It was updated and distributed weekly Details Number of safety observations % of Pre-Job Briefing Documented % of Utilization of PPE % of Safe Work Practices Number of Recordables Recordable Injury Rate

Safety Performance Scorecard

11

At least one subcontractor is considering having their personnel trained in HPI as a result of the experience on this project

The field oversight by CNP and contractor safety representatives was seamless

New Approach Brought Positive Results

Project is ahead of schedule with positive feedback from contractors on 3rd party’s oversight

All sections are electrically complete and have been energized

There have been 2 recordable cases on the project to date

Contractors freely shared lessons learned in regular meetings with operations and safety personnel

Safety issues were addressed immediately with no hesitation

12

With only the clean up phase of the project left, CenterPoint Energy has chosen to use the 3rd Party contractor to carry out the same duties for contractors conducting normal construction activities

This started the week of April 9th, and there has been positive feedback from the contractors being observed

We will continue to evaluate the use of this service for future projects

What’s Next?
