Our Vision is:

To be the company of choice for our people and our clients by delivering safe and quality work.

Thus, we are committed to:

  • Maintaining a safe and healthy workplace;

  • Providing a high-quality product; and

  • Using environmental best practices.


ISNetworld (ISN) is the subcontractor information system we use to move subcontractors through the pre-qualification process. This system helps us select subcontractors that meet the high standards set by our Company and our Clients. 


Consequently, subcontractors performing services for Surerus Murphy Joint Venture projects are required to become subscribers to ISN, and to apply for work through the ISN website.

If your company is a current subscriber, there is no additional fee; however, please ensure your company has completed the requirements specific to our Company. If your company is new to ISNetworld, there is an annual fee for this service.

To sign up with ISNetworld, please contact the ISN Customer Service Team at 

1-800-976-1303 or visit their website (as per link above).
