BIM and DIGITAL ENGINEERING

Home | Services | Tunnelling | BIM and Digital Engineering

At PSM we are leading the way in developing fully integrated / parametric models. With the ability to delivery live feeds to design development we service our client with the latest in BIM technologies.

PSM applies advanced 3D modelling, visualisation and monitoring methods to design and build excavations which do not adversely affect the existing environment. We consider our innovative approach to BIM to be industry leading and always endeavour to achieve the best unique engineering solution for every project we are involved in.

 OUR APPROACH

The prime emphasis of the services provided by PSM ensure detailed / accurate transfer of information from the designer to the construction team and the owner to provide practical outcomes. We strive to continue leading developments within the digital engineering space to progressively move the tunnel infrastructure into a modern digital age with data rich models.

We ensure a detailed model is available at any stage of the design process. This enables early detection of design clashes, volume estimation, calculation of construction cost, determine constructability and communication of design progression / intents.

We use a long list of design programs and industry standards to find the balance of technological advancement and project delivery. We seek harmony between the clients requirements and construction needs.

 Projects

Cross River Rail - Caverns

The project consists of 4 new major underground station, mined tunnels and cross passages. Located underground within metres of inner city Highrise buildings, sewer, piles and low cover to the surface. The modelling accuracy of stations was essential as structures and services came within millimetres of primary tunnel support.

We provided weekly model updates for a live and interactive Design. The models met LOD500 requirement and had one of the most complex metadata level requirements seen at the time on an infrastructure project in Australia. This was due to not only complying with state (TMR) requirements but stringent QR and development authority requirements. Each weekly submission consisted of 3 file format native, .IFC and .nwc outputs. 

Cross River Rail - shafts

In addition to the tunnelling scope PSM was awarded 4 temporary shafts located at the southern portals. Due to site constraints and geological conditions very unique shafts were designed and modelled.

Rozelle Interchange

For the Rozelle Interchange Project PSM was required to provide regular model updates for federation into the project model. The model had to meet the LOD & Metadata requirements as defined in the project DEMP.

Tunnel model development was data driven and semiautomated. For the road tunnels the lead contractor provided PSM with a minimum component envelope (D-Line) in the form of raw data (excel spreadsheets). This process enabled us to quickly and accurately model and adapt models from updated D-line geometry. Algorithms were used to automate development of the 3D excavation temporary and permanent profiles.

The script files used to generate our models were also used to generate setout tables which were provided to the construction surveyors for tunnel setout. This process ensured that the same data used to generate the models was provided as final setout data ensuring seamless delivery.

sydney metro

For the Sydney Metro Project PSM was required to provide regular model updates for federation into the project model. The model had to meet the LOD & Metadata requirements as defined in the project DEMP.

Tunnel model development was data driven and semiautomated. For the station Caverns tunnels minimum clearance opening in the form of a 3D Surface was provided by the client. From this the tunnel profiles were created and the models developed to ensure that the tunnel fitout would comply with all project requirements.

 

wynyard walk

For Wynard Walk PSM provided model updates for federation into the project model. Whilst rudimentary by todays standards, this was one of the first applications of BIM modelling in the Australian Infrastructure environment and was vital in managing interaction between the works and existing services / infrastructure.

As these tunnels where within (mm) of services design tolerances where at a minimum and the level of error was small.
