Orange Street Widening
The project included widening the existing 20 foot wide 2-lane asphalt road with to a 38 foot wide 2-lane concrete curb and gutter section. Orange Street crosses known oil and gas pipelines owned by Shell Pipeline Company (Shell), Seminole Pipeline Company (Seminole), and Houston Pipeline Company (HPL); all which GCE had to deal with.
GCE performed alternative roadway alignments, a field survey, environmental services, a hydrologic and hydraulic analysis, preparation of a preliminary design report for the improvements, as well as preparation of final design plans and contract documents.
The proposed project included removing the existing asphalt pavement, constructing a 2-lane concrete curb and gutter pavement section, improving the Mykawa Road and Orange Street intersection, and designing a storm sewer system. Work also included analyzing conflicts with Shell, HPL and Seminole pipelines and providing recommendations on the relocation or if necessary, removal, of the pipelines at conflicting locations. Conflicts with other existing utilities such as sanitary sewer, water, electricity, and gas were analyzed, and recommendations were given to resolve them.
Additionally, GCE designed a 12-inch diameter waterline from State Highway 35 to Woody Avenue to improve and provide continuity in existing water supply networks for the surrounding areas of Orange Street. Work included performing an analysis that determined pressure distribution along proposed lines based on available network information from the City. GCE designed connections between old and new waterlines at various intersections and replaced an existing waterline along Woody Road with a new 10” waterline.
GCE also provided construction services, which ended 2012.
