Rail Expansion Southeast/Purple Line Corridor
Houston METRO, thru the Houston Rapid Transit – Joint Venture (HRT), engaged LAN to advance the Preliminary Engineering design of the South East Corridor, through final design and construction. HRT is the Design-Builder under a “hybrid” design-build delivery system for METRO in its system-wide expansion by the facility provider.
As the prime design consultant, LAN worked with HRT to prepare a final integrated design of the South East Corridor. The new segment is 6.14 miles, connecting the CBD with the University of Houston, Texas Southern University, and the Palm Center in south east Houston.
The design scope required public and private utility adjustments; street modifications to accommodate at grade rail operations within the street right-of-way; urban design and landscaping along the corridor; station design for 6 new light rail stations; permanent traffic signage and signal design; temporary maintenance of traffic and access design during construction; right-of-way and parcel identification; stormwater hydrology and hydraulic modeling for street drainage inlets, storm piping, and bridges; guideway and track design; and yard track and maintenance facility structures.
LAN worked with the project team to advance preliminary design in just eight months. The accelerated schedule was made possible by the hybrid delivery system and a team of 18 specialty sub-contractors. All team members including sub-contractors worked in LAN’s Houston office.
