A civil engineering company designs roads, transit lanes, grading, drainage and utility works, coordinating with specialists responsible for signals, electrical systems, track and communications. The objective is to develop infrastructure that functions as a coordinated system and is practical to maintain. [Discuss Your Project](https://tsigroup.ca/contact/)  01 ## Site Investigations & Infrastructure Assessments Engineers review survey data, ground conditions, and existing utilities and infrastructure records. Investigations identify constraints that affect construction and future operations. Findings determine where additional testing or specialist assessments are required. 02 ## Transit Roadways & Pavement Design Designs for bus lanes, terminals and stopping areas account for vehicle loading, repeated braking and turning movements. Engineers select pavement structures and materials suited to anticipated use and ground conditions. Details address transitions, drainage and connections to existing roads.  03 ## Grading & Drainage Systems Civil designs establish elevations and drainage arrangements for corridors, stations and supporting facilities. Engineers assess runoff, collection systems, storage and discharge connections. Particular attention is given to low points, accessible routes and locations where ponding could affect operations. 04 ## Traffic Signals & Transit Priority Transportation and signal specialists evaluate measures such as transit signal priority, queue-jump lanes and revised intersection controls. Analysis considers transit travel times alongside pedestrian movements and other traffic. Civil engineers coordinate road geometry, equipment locations and underground infrastructure with these systems.  05 ## Intelligent Transportation System Interfaces Engineers coordinate the infrastructure supporting vehicle detection, passenger information and operational monitoring. Civil work may include equipment foundations, cabinets, conduits and access provisions. Communications and system functionality are developed by the appropriate specialists. 06 ## Utilities & Multidisciplinary Integration Transit projects often require utility protection, relocation and new service connections. Engineers coordinate these works with structural, electrical, architectural and transit system designs. For rail projects, specialist teams lead the design and implementation of track, traction power, signalling and related technical systems. 07 ## Constructability & Lifecycle Reviews Engineering reviews consider installation access, construction sequencing, and equipment replacement over time. Designs incorporate inspection and maintenance provisions where needed. Comparing alternatives helps owners balance capital costs with operating and renewal requirements. ## Talk to our team about your transit project Contact TSI to discuss transit engineering services for your transit project.
