RPS BIM in Structural Engineering
Before BIM
Engineer develops design concept, produces
sketch's
Technician produces detailed drawings from
sketches
Engineer carries our design analysis
independent of drawing production
Mark-ups used to progress design
BIM alters the entire way in which a project is
procured, delivered, constructed and operated
It is both a process and a deliverable
With BIM
BIM Manager/Design Engineer models basic
structural concept model
Using 1 central live model:
– Coordinates the development of the model/design
– Carries out design analysis on model, input results
directly into model
– Coordinates the production of drawings, schedules
Utilise BIM approach on all structural projects

UHG New Ward Block
3 story steel structure with comflor concrete
slabs
Connecting into 2 existing buildings –
underground M&E tunnel
Exchange 3D information with the contractor
Extract quantities – Issues with suppliers
![Page 6: BIM en Ingeniería Estructural](https://reader031.fdocuments.in/reader031/viewer/2022013004/5695d0641a28ab9b02924617/html5/thumbnails/6.jpg)
Industrial Facilities (Northwest)
2 similar steel structures – combined office and
production space – steel and comflor
construction
Large glass expanses – global stability issue
Model developed from Architects massing
model
Tight project deadline – overlapping disciplines

Industrial Facility Dublin
3 story steel frame – comflor slabs
14000m2 of office, production, labs & plant
7000m2 of existing structure to be connected
into
All structural drawings produced form 1 live
integrated Revit model
Design carried out using information transfer
to Robot SA

Industrial Facility DublinAdvantages of Using BIM – Complex Design
Production areas 13 m spans – roof trusses to
hang 2 floor – plant areas on 1st and 2nd floors
Existing facility to remain operational – no
foundations near structure – cantilevered floors
Large canopy to delivery area
5 staircores/lift shaft large spans foundations to
cantilever
Cater for future expansion

Industrial Facility DublinAdvantages of Using BIM – Existing Structure
Connect into existing portal frame structure
Add link corridor, access ramps, remove lift shafts
Add additional brize soleil frame to hide building
Protect existing block façade with protrusions

Industrial Facility DublinAdvantages of Using BIM – Revisions, Revisions, Revisions
Client made numerous changes during
project to adapt to changing market
conditions.
BIM model allowed design team to asses
impact of changes on structure, design and
quantities.

Industrial Facility DublinAdvantages of Using BIM – Exchange of Info with Robot
Information transferred to and from Robot
SA to design and analyse structure.

Industrial Facility DublinAdvantages of Using BIM – Information Extraction
Able to extract steel quantities from BIM model
Issue with availability of ASB’s
Compare IFT and IFC quantities and track
changes

Industrial Facility DublinIssues with Using BIM
Ownership/Transfer of Model
Pre existing contact no provision for BIM –
No EIR or BEP.
Client requested model in native Revit
format
Is a model a drawing?
Existing Work Practices/Understanding
Can’t we just Copy & Paste
Just cheat “make it work”
It has to go Friday.
Sure just CAD that section
Interoperability
Information gets lost during transfer
Issues with IFC Import v Export
Nodes in Analytical model not meeting
Requirement for post processing in
import software.

Summary
Utilise BIM Approach on all structural projects – has entire way in which a
project is procured, delivered, constructed and operated .
Allows detailed information to be developed and extracted at an early stage
Many advantages to allow designers to visualise and analyse design options
Issues still exist in the area of Interoperability, Ownership & Understanding
