Description:

The model defines the geometry of the major tunnel. 


Usage:

The model is used to ensure the clearance for free passage through the tunnel, as well as clearance for assets inside the major tunnel.

The model is used to build the tunnel.


Content:

3D model which contains the external geometry for major structures as well as modelled elements regarding installations such as lines, surfaces or objects.

It shall be possible to handle the model for a computer with ordinary specifications. It shall be possible to switch off layers with many details,
which may cause an impediment when rotating and checking the model.

The 3D model may either be submitted as a total model or, as a number of sections of the model which may be inserted as references in the shared model.

The 3D model shall, as a minimum, be divided into components in accordance with DANBRO+ List of Elements on level 4, standard structures, as indicated in DANBRO+ (www.danbroplus.dk).

Components to be named and numbered in accordance with "Operation & Maintenance Manual".​​

The above mentioned standard elements shall be named as described and, any sub-components shall be unambiguously marked, thus ensuring that each element and each sub-component can be identified unambiguously within the model.

Coherence between databases for ‘Operation and Maintenance’ and 3D model

The 3D model for the major structures shall be divided into model elements and named in such a way that the standard elements, in the database ‘Operation and Maintenance’, can be attached to a corresponding model element in the 3D model, cf. description in ICT for the tender.

 

Level of detailing for 3D models:

Elements of a diameter less than 50mm should not be modelled, unless essential to the scrutiny of the structure.

‘As built’ 3D model:
The ‘as built’ model shall be modelled to Level of Information 4, meaning that all elements shall be modelled as physical realisable solutions.
The model shall be unequivocally detailed so that it may form the basis for “Operation and Maintenance”.


Working models and project models:

Working models and project models shall be submitted in the degree of detailing suitable for the stage.

The Project Model for scrutiny shall, as a minimum, contain a geometrically correct 3D model of the entire construction, of which the main geometry for the individual sub-components are modelled theoretically correct.

Concerning the reinforcement, the contractor shall, as a minimum, display examples in 3D for selected components such as:

  • Construction joints
  • Waterproof joints


Nonconformities:

Construction Drawings.
Excavation and backfilling, waterproofing, bridge surfacing.


Updating frequency:

Preliminary 3D models shall continuously be submitted to the employer. Furthermore, the completed 3D models shall be available in an updated version at each supply of  Project Documents to the employer.

At project initiation a timetable shall be prepared for when to submit 3D models. Time schedule to be prepared in collaboration with the employer and, shall be approved by the employer.

Following the employer’s approval of the Project Documents, the agreed changes shall be implemented into the models.
When the contract terminates ‘As built’ 3D models shall be available for the structure.​​​​

The providing of data shall take place in accordance with the names of layers mentioned below:​​
