Overview

Infrastructure work is defined by its interfaces: civil alignments meet structures, structures meet buildings, and utilities run under all of it. The model brings civil, structural, architectural and building services together so those interfaces are resolved in one place.

Layer by Layer

What each discipline models

  1. L.01Civil / Site

    Terrain, alignments, roads, drainage and utilities.

  2. L.02Structural

    Bridges, platforms, retaining elements and structural frames.

  3. L.03Architectural

    Station buildings and passenger facilities.

  4. L.04MEPF

    Station building services and systems, where in scope.

  5. L.05Coordination

    Interfaces between civil, structural, architectural and building services.

Typical Challenges

Where these projects go wrong, and how the model prevents it

  1. C.01

    Civil alignments meet structures at many points

    Approach

    Terrain, alignments and structures are modeled on one coordinate system and checked together at every interface.

  2. C.02

    Buried utilities run under foundations and drainage

    Approach

    Underground utilities are modeled with their levels and clash-tested against foundations and drainage.

  3. C.03

    Station buildings sit on platforms and site works

    Approach

    Architecture, structure and site are federated, so interfaces at platform level are resolved in one place.

Coordination Focus
  • Civil alignments against structures and retaining elements
  • Underground utilities against foundations and drainage
  • Station buildings against platforms and site works
  • Building services interfaces at station level
Deliverables
  • Site model of terrain, alignments, roads, drainage and utilities
  • Structural model of bridges, platforms and retaining elements
  • Architectural model of station buildings
  • Federated model with clash reports and a tracked issue log

How the Work Runs

Process

  1. 01

    Brief & inputs

    Drawings, models, standards and templates collected, with scope agreed by discipline and level of detail.

  2. 02

    Discipline modeling

    Each discipline modeled on the project's shared coordinate system, to your naming and template standards.

  3. 03

    Federation & clash cycles

    Models federated and clash-tested, with issues tracked through resolution with the responsible trades.

  4. 04

    Sign-off & handover

    Issue log closed out and coordinated models and drawings handed over, with a change log.
