Introduction

TÜV SÜD is a universally recognized brand

for safety, security, and sustainability.

Reflecting its heritage of German engi-

neering and technical excellence, TÜV SÜD

has grown to a globally recognized Digital

Transformation expert in the Architecture,

Engineering and Construction (AEC) sector,

helping governments and industries pace

the excellence of buildings across the entire

asset lifecycle.

TÜV SÜD made a bold decision in 2017: to

objectify the importance of Digital Building

Lifecycle Solutions in its newly built 18,900

sqm ASEAN headquarters in Singapore,

known today as TÜV SÜD @ IBP. This proj-

ect highlights the impact of digital meth-

ods such as Building Information Modelling

(BIM), Common Data Environments (CDE)

and Computer Aided Facility Management

(CAFM) towards both the project and the

building.

TÜV SÜD is guided by its belief that digita-

lization across a building’s lifecycle clearly

focuses on achievements that can be mea-

sured in safety, quality, and sustainability

gains, as well as in performance and pro-

ductivity benefits.

We must ensure that safety, sustainability,

“We believe that Digital Prototyping and

Digital Twin principles are a prerequisite for

a successful building lifecycle and for a safe

and sustainable asset operation that will

last for decades. The design phase is the

core of the asset lifecycle to virtually con-

struct, simulate and optimize the building

design for construction and operation.

technical reliability, and user comfort are

clearly integrated while planning the later

building. The design stage plays a key role

in a technically and commercially successful

building lifecycle, and it is when there is the

best potential to optimize the Total Costs

of Ownership (TCO) of the building,” says

Tobias Schmidt, Global Manager for Digital

Lifecycle Solutions in the Real Estate & In-

frastructure division of TÜV SÜD

optimization portion of BIM and CDE for

better building safety, sustainability, perfor-

mance and operation,” explains Gilbert Lau,

the Project Manager at TÜV SÜD.

Going Beyond Known Market

Practices

TÜV SÜD @ IBP is a brownfield project

located on a structurally difficult area

and features a sensitive Electromagnet-

ic Compatible Laboratory that should not

have been affected during the project.

Keeping all the relevant stakeholders

across all the lifecycle phases located in

various countries was one of the most

critical prerequisites for the project. That

is why TÜV SÜD implemented digital in-

formation management with BIM based

on ISO 19650 as a standard, by leverag-

ing on Autodesk Construction Cloud as

the core project platform.

With this Common Data Environment and

the lifecycle-embracing Exchange Infor-

mation Requirement (EIR), TÜV SÜD im-

plemented all construction and operation

relevant use cases into the design stages

for both Shell & Core and for the Fitout

design.

These requirements included Design for

Maintainability (DfM), Design for Building

Safety as well as all required energy and

sustainability optimizations towards the

Singapore Green Building Mark.

The authored Project Information Mod-

els in native Revit were also built up to

serve as a later resource for the Digital

Construction Inspection. This allowed for

monitoring of both construction prog-

ress and tolerances as well as “Built as

Planned” compliance, e.g., through im-

plementing Scan2BIM overlays.

For Facility Management and CAFM tools,

the Revit models were also authored

and checked to be the ‘Single Source’ for

various As-Built documentations in IFC

and COBie format for the later internal

and external contracted Facility and As-

set Management.

This complexity of use cases for design,

construction, and operation, together

with the required high maturity of the Re-

vit-based Project Information Models as

well as the necessity for excellent export

qualities towards IFC and COBie howev-

er posed a major challenge as many local

Consultants and Contractors were not

ready to digitally deliver a project at that

level.

“Many contractors see BIM simply as 3D

modelling and as a tool to perform Clash

Detections. Often, the market practice is

to carry out native design in 2D and to

do post-design modelling, translating

the 2D drawings into a 3D model with

BIM. With this local approach, we fore-

casted a slow and risky project. As the

building owner to carry both the con-

struction costs and the operational ex-

penses, we wanted to see especially the

“We wanted to go beyond the locally typi-

cal LOD300 BIM model requirement for the

project submission, pursue the digital pro-

totyping approach and utilize all measures

to order to manage our building project with

high efficiency and predictability, as well as

sustainability.”

Together with TÜV SÜD’s internal BIM

management as well as the Sustainability,

Construc t ion and Faci l i ty Management

experts onboard, Nakano as the nominat-

ed contractor integrated all the use cases

specified by TÜV SÜD: for the construction

design and further use, completely new and

sophisticated Revit models had been devel-

oped by Nakano as basement for TÜV SÜD

experts to integrate the building-related use

cases, such as:

•Simulations for structural and thermal

layouts, for lighting and aircon / venti-

lation optimizations

•Model checks for fire safety and local

fire compliance as well as for Wi-Fi

signal coverage within the building

•Model checks and trade optimizations

towards Design for Maintainability, e.g.

by using maintenance space models and

FM advisory protocols

• Integrated calculations and measures

towards Singapore’s Green Building

Mark

Autodesk Customer Success Story

Building A Digital Twin

From the commencement of the project,

Autodesk solutions were adopted as the

native ecosystem by the project team

that comprised real estate experts, finan-

cial specialists, BIM experts, construc-

tion experts, and facility managers within

TÜV SÜD.

“We chose Autodesk as the most effi-

cient project ecosystem to cover all core

trades, such as architecture, MEP and

structural engineering being processed

in a single native environment,” explains

Tobias Schmidt. “Also, Revit is a very flex-

ible core data source and information

management basement, e.g. to extract

other open formats we needed for sim-

ulations, cost counting, construction in-

spections and facility management, such

as IFC, gbXML and COBie.”

TÜV SÜD

TÜV SÜD found that workflows such as

Change Management (Request for Chang-

es), the User and Facility Management

Involvement, the Integrated Digital De-

livery (IDD) and the handling of various

deliverables and results can be expedited

to complete the entire Building Lifecycle

Services without investing any additional

time.

Besides using native Revit models, BIM

Collaborate Pro as the Common Data

Environment towards the essential pro-

ductivity according to ISO 19650 is the

lifecycle embracing data highway to orga-

nize and manage not only the project data

but communication as well as the quality

control of every stage of the project.

Models created in Revit took on the es-

sential role of facilitating successful

digital prototyping. Navisworks was de-

ployed for clash detections, and to run

various Design for Maintainability, Con-

structability and Design for Building

Safety tests and checks.

Dynamo was used by TÜV SÜD to run

complex Model Checks including As-built

Documentation Compliance or towards

proper pressure cascades and air venti-

lation performance in unique spatial set-

tings within the building.

During the construction phase, the BIM

models were used to perform the close-

meshed periodical ‘Built As Planned’

checks along with tolerance validations

and digital progress monitoring: Contil-

io’s Scan2BIM overlays helped to extend

the quality and risk management to a

combined remote-onsite construction

assurance, to dramatically lower onsite

and travel costs for TÜV SÜD’s Construction

Inspectors.

The data from Revit models have been also

used to review the Building Management

System (BMS) layout and construction

accuracy.

For the commission and handover to op-

eration, TÜV SÜD utilized Autodesk Forge

functions and the BIM 360 Ops to achieve

a fast and accurate ramp up of the internal

and external Facility Managers. Also, via

Revit-based IFCs and COBie sheets, Nakano

and TÜV SÜD delivered the required digital

building documentation to set up the build-

ing’s Computer Aided Facility Management

(CAFM).

As the successful project outcome, TÜV SÜD

delivered the planned Building Lifecycle

Solutions and optimizations with the inter-

disciplinary use of Autodesk tools, achieving

the following technical KPIs:

•Reduction of the facade’s thermal value:

with BIM and BIM-based simulations,

an achieved Envelope Thermal Transfer

Value (ETTV) of 32.40 W/m2, which

is even 35% better than Singapore’s

current code requirement

•Lighting costs improved by 51% over

local code requirements

•Energy savings due to optimized and

fully balanced aircon and ventilation

systems with energy savings of 17%

higher than the code requirements

Autodesk Customer Success Story

Optimizing productivity and build-

ing performance right from the de-

sign phase.

By carrying out the Construction De-

sign directly in Revit, the project team

saw design time savings on authoring

and coordination level of 70% compared

with the market habit of “post-design

modelled 2D”, which avoided the design

creation in CAD and then translating it

into 3D models.

TÜV SÜD

The use of Autodesk Construction Cloud

as the project Common Data Environment

brought Information Management time

efforts of nearly 60%, due to the pre-de-

fined workflows and through the central

data drop handling among internal and

external experts.

The Revit ‘mother models’ avoided the

usual costs for remodelling, e.g. through

data errors and re-development of IFC or

COBie files, that can easily make up S$60-

150,000 per project, based on TÜV SÜD’s

project reviews in Asian markets.

During the pre-construction phase, TÜV

SÜD customized Model Checks brought

further savings. By implementing Model

Checks for code compliance and for the

automated BIM model audits, the proj-

ect saw a reduction in BIM management

costs and for Risk Management by at least

50%. This was executed via Navisworks,

the customizable Revit In-Built Check-

er and TÜV SÜD Dynamo scripts, which

helped to cut down technical audit time

for highly repetitive tasks, such as fire

and sprinkler system audits, that manu-

ally last e.g. three to five hours, down to

just 30 minutes.

The application of Model Checks also

brought significant savings for rework-

ing. As many construction errors occur

due to raw materials and constructability

issues, the comprehensive use of Model

Checks helped to avoid the traditional

overspending of 30% (local market aver-

age) of the construction costs on rework

due to undetected design errors, which,

in turn, enabled the team to avoid major

rework issues.

“By using BIM, we could plan and visual-

ise the entire project during the pre-con-

struction stage. We’ve been able to de-

tect clashes in mechanical, electrical and

plumbing (MEP) before construction be-

gan, thereby significantly reducing the

amount of rework, and mitigating po-

tential risks,” said Kevin Kwan, Project

Manager of Nakano.

Through digitally assisted construction

related data services, such as Scan2BIM

overlays and a digital inspection, saved

TÜV SÜD saved travel and freewheel pro-

cess costs in the six-digit range.

This was especially helpful to the project

team as almost 50% of the TÜV SÜD’s

project experts were based in Germany.

The ability to operate remotely and ef-

ficiently meant that they could save on

colocation costs.

The Results

Starting building operation by January

2021, TÜV SÜD’s digital prototype has

resulted in a ‘touchable’ Digital Twin in

Singapore with many use cases across

design, construction and commissioning

implemented.

Today, TÜV SÜD’s new ASEAN headquar-

ters at 15 International Business Park in

Singapore is a testament that digital twin

projects combine both the proper spec-

ifications and strategies with the right

technologies to ensure synergies and

value partnerships among all the project

stakeholders, meaning TÜV SÜD as ap-

pointing party and the Contractors as well

as technical experts, can come true. TÜV

SÜD has proven that building safety, sus-

tainability and performance do happen

with the lifecycle - embracing knowledge

into relevant data that help to achieve a

building that is truly a better place for

working and living.
