• Over 25 miles of natural gas lines were installed
• Polyethylene plastic and steel pipe were used
• Main pipe diameters ranged from 2” up to 12”
• Design pressures: Intermediate Pressure (IP) and High Pressure (HP)
• Hundreds of commercial and residential gas service lines
• Open cut and horizontal directional drill (HDD) methods

Electric Transmission Overview:

• Replaced overhead tower-mounted transmission facilities with underground duct banks
• Relocated over 11 miles of 138 kV transmission line under frontage roads
• Installed dual 9-8” PVC concrete encased duct banks
• Open trench, horizontal directional drill, and auger bore methods were used

Fiber Optic Overview:

• A T & T OSP Underground Fiber Relocations
• Phonoscope OSP Underground Fiber Relocations
• TV Max OSP Underground Fiber Relocations
• Installed 3 - 1 1/4” Multi-colored HDPE Innerducts

Responsible for the coordination of construction schedules, permitting, and approval with TxDOT, City of Houston, Harris County Flood Control District, U.S. Army Corp of Engineers, Texas Historical Commission, as well as with various Departments within CenterPoint Energy.  All designs were in accordance with CenterPoint Energy policies and guidelines, as well as with federal, state, and municipality requirements.

Binkley & Barfield, Inc. is the only certified vendor selected by CenterPoint Energy to provide utility engineering for all six services, including electric distribution, natural gas distribution, natural gas transmission, electric transmission, telecom, and inspections. 

Together we are the one source for utility engineering services.

• Utility

On what is referred to as a Houston “danger zone,” the 610/290 project will improve traffic flow and congested roadways, which have contributed to over 200 vehicle accidents per year. Binkley & Barfield, Inc. provided the critical first step by providing relocation designs for all natural gas facilities located along this congested 4 mile interchange section of US 290 and IH 610. 

 Providing complete natural gas utility services, project responsibilities include:

• conflict analysis
• field surveying
• subsurface utility engineering (SUE)
• records research
• utility agreement
• relocation design
• plan and profile drawings
• cost estimates
• utility coordination
• permitting
• construction management

Overall, this project consisted of installation of over 4 miles of polyethylene plastic and steel pipe.  The main pipe diameters ranged from 2” up to 12” of Intermediate Pressure (IP) and High Pressure (HP) lines.  Designs for open cut and horizontal directional drill (HDD) methods were used, keeping in accordance with CenterPoint Energy policies and guidelines, as well as with state and municipality requirements. 

This project will extend the IH-10 West and IH-610 reconstruction, where Binkley & Barfield provided complete utility services.  We support communities by providing utility designs for much needed infrastructure relief, aiming to reduce delays and injuries for the 250,000 vehicles traveling through this intersection on a daily basis. 

Preserving the integrity of our historic communities...

• Natural Gas
• Utility

Preserving the integrity of our historic communities, BBI provided complete utility engineering services for the replacement and relocation of an aging steel gas line hung under the historic Sabine Street Bridge.  The project included replacing the gas line with a double coated 12 inch steel pipe and employing open-cut and horizontal directional drill (HDD) methods to relocate the pipe underground.  The directional bores were completed under Allen Parkway and historic Buffalo Bayou, spanning 1,550 linear feet in length and reaching an ultimate depth of 85 feet below natural ground level.

Keeping the natural setting while upgrading natural gas pipelines not only enhances community safety but preserves our community's integrity. 

Supplying Innovative Solutions to Meet Budget Constraints and the Needs of a Community...

• Natural Gas
• Utility

Supplying innovative solutions to meet budget constraints and the needs of a community, BBI designed two alternate designs for an existing 18" high pressure suspended crossing in the Southwest corner of the IH-610 Loop.  BBI provided route design, plan and profile design, cathodic protection support, specifications, permit coordination, right-of-way coordination, traffic control design, pavement restoration, and construction support.
 
The first design was for a 1200 LF horizontal directional drill (HDD) under Brays Bayou, 50' below natural ground.  The HDD rig would be set up within an existing City of Houston (COH) wastewater treatment plant, which included coordination and approval from the COH legal department, land and right-of-way department, pubic works department as well as the treatment plant management.  The exit point would be within an existing CNP fee strip, 20' from a synagogue, with the pipe stringing area encompassing an electric transmission right-of-way and entry from a substation.  Coordination and approval with all required parties for the proposed work was completed.  Harris County Flood Control District (HCFCD) approval was also received.
 
Due to budgetary requirements, an alternate design was completed to install new reinforced concrete supports to replace the aging wood supports.  To assist with additional HCFCD requirements, which would include additional costs and time, the existing wood support column locations were cleaned out and used.  Two dual 18" concrete columns with concrete caps were used for the two center supports and two single 18" concrete columns were used for the end supports.  The design included specifications for the dual rollers with straps, as requested by the client.  The line was installed and put back in service without any delays.

BBI is the ONLY certified vendor selected by CenterPoint Energy to provide utility engineering for all five services including:

• Power Distribution
• Natural Gas
• Telecommunication
• Utility
• Construction Inspection Services

Replacing an aging pipline under the historic Sabine Street Bridge

• Natural Gas
• Utility Coordination

The project consisted of replacing an aging gas line hung under the historic Sabine Street Bridge with a 12” steel line in two directional bores. BBI provided route design, plan and profile design, cathodic protection support, traffic control design, pavement restoration, permit coordination, cultural survey coordination, field surveying, and construction support for the directional bore under Buffalo Bayou, just outside of downtown Houston, Texas. The first 320 LF bore was under a major thoroughfare, Memorial Drive, and a 42” waterline outside of a City of Houston water plant. The second directional bore was under Buffalo Bayou and Allen Parkway and consisted of a double coated 12” steel gas line approximately 85 feet below natural ground and 1,550 LF in length.
