At SEC, the success of our projects stems from our ability to maintain efficient productivity while staying within our clients’ budget and schedule constraints. Our clients trust us because we invest in the life of a project – from its foundation to completion. This is evident in the following project:

Program Management Office (PMO),
North Texas Tollway Authority (NTTA)

SEC currently manages the preparation of contract documents and specifications for the development of new corridors and improvements to existing toll roads in the Dallas-Fort Worth Metroplex. To ensure specifications meet standard requirements and are constructible, we closely coordinate with NTTA departments, the American General Contractors and the contracting community.

Specifications developed are:

  • Natural Grey or Integrally Colored Concrete
  • High Friction Surface Treatment
  • Excavate and dispose of industrial waste
  • Crushed limestone aggregate ground cover
  • Interlocking articulating concrete block with cable revetment system

Projects managed are:

  • Southwest Parkway/Chisolm Trail – a new corridor that required coordination across six separate sections of roadway and four separate managers, all at an accelerated schedule
  • All Electronic Toll Collection for President George Bush Turnpike (PGBT), Addison Airport Toll Tunnel (AATT) and Dallas North Tollway (DNT) – conversion to cashless tolling
  • PGBT Western Extension (SH 161) Phase 2 Gantry Construction
