This document discusses integrating building information modeling (BIM) between permanent and temporary construction works. It describes Costain's experience with 3D modeling on projects in industries like oil and gas. Temporary works are less defined than permanent structures but there is value to modeling them. The case study details a project that modeled scaffolding and pressurized habitats for construction within a live gas plant, allowing all stakeholders to review proposals virtually. The summary emphasizes that modeling temporary works helps visualization and planning, and will become standard as more see its benefits.

1. BIM Integration Between Permanent
and Temporary Works

2. Introduction
▪ Costain In House Engineering and Design
▪ Delivering projects for Oil & Gas, Power,
Nuclear, Rail, Highways and Water
▪ Over 30 years 3D modelling experience built
on Nuclear, Oil & Gas projects
▪ Temporary Works Design Capability
▪ Multiple CAD platforms

3. BIM Permanent & Temporary
Works
▪ Nuclear, Oil & Gas, highly regulated industries,
even old models align with much of BIM
requirements. Structured hierarchy etc.
▪ Permanent Works, data rich models BAU
▪ Temporary Works, less defined, but recognised
added value
▪ Design models are shared daily with the design,
project and construction teams. (Navisworks)
▪ There is generally a wider appreciation of the
benefits of the model
▪ Designers seconded to site to maximise the use
and demonstrate the benefits of the model

4. Case Study
▪Construction within a Live Gas
Plant

5. The Story Behind the
pictures
▪ Live Gas Plant
▪ No Hot Work (Welding) without special precautions
▪ Requirement for Pressurised Habitats
▪ Scaffolding required for Habitats
▪ Access requirements specified
▪ Scaffolding contractors proposals are incorporated into
3D model
▪ Proposals reviewed with all stakeholders and modified
to incorporate final requirements
▪ Linked to Primavera schedule to demonstrate to client
what is happening and when.

6. Habitat Location and Installation

7. Bring the site to the office
▪ Easy Visualisation of
proposed concepts.
▪ Review the
requirements remotely
▪ Can be shared in
Navisworks

8. Self contained in Navisworks for construction review and
planning
Only 6 scans, but enough to make an informed decision
Bring the site to the office

9. Laser data output in 2d form

10. Excavations

11. E3D BIM Libraries
Parameterised
components
available from a
library
Expanded to
include temporary
works

12. Summary
▪ To realise the benefits of temporary works within
our 3D model environment.
▪ Demand for more detail will increase as more
people see the benefit
▪ Seek to use vendor’s BIM libraries where
applicable
▪ 3D Modelling of Temporary works will become
Business As Usual, just as the permanent works
▪ Questions
