Control the corridor from centreline out.
We develop road models around horizontal alignment, vertical profile and repeatable cross-sections. Junctions, drainage and roadside assets stay tied to that geometry.
Every roadside element depends on the alignment.
Road and transportation BIM turns survey, alignment and design criteria into a coordinated three-dimensional corridor. Carriageways, junctions, pavements, kerbs, verges, barriers, signs, lighting and drainage are developed within one controlled geometric framework.
Inconsistent references create cumulative errors. A changed profile can break drainage falls, alter tie-ins and leave road furniture or utilities positioned against superseded edges.
CNE builds corridor relationships so approved changes propagate predictably. We coordinate the road with terrain, structures, utilities and adjoining developments while keeping chainage and design references traceable.
From alignment to external interface
Horizontal geometry, vertical levels, chainage and design controls are established from the approved road basis.
Lanes, shoulders, medians, kerbs, verges and earthworks are generated through controlled assemblies and target conditions.
Intersections, tie-ins, turn lanes and level transitions are developed against sight, grading and drainage requirements.
Surface and layer geometry is represented to the agreed detail for quantities, interfaces and construction staging.
Barriers, signs, gantries, markings, lighting and street furniture are placed against current corridor geometry.
Catchments, gullies, channels and pipe routes are checked against road falls, utilities and structural constraints.
Corridor changes stay connected.
Dependent geometry is tied to controlled references rather than redrawn after each design revision.
Existing roads, structures and development boundaries are checked where level and geometry tolerances tighten.
Surface falls and collection systems are coordinated as one interface instead of separate design layers.
Build a road model that follows the design.
Send us the survey, alignment, profiles and delivery requirements. CNE will define a corridor modelling scope suited to review, coordination and construction.
