It's one thing to have the technology at your fingertips
and use it to it's full extent. Some people just like to
do things the way they have always done it, even if
it's inefficient, costly and not very accurate.

Quality Management
It has been estimated
that approximately 10%
of the cost of construction
rework is caused by
delays in detecting the
defects. Timely and
accurate quality
management practices
can hence save money
and expedite project
schedules.
Ref: David Arditi, H Murat Gunaydin, Total quality management in the construction process, 1997

Whose is responsible for the disaster?
Designer, Contractor or Site Engineer ?

Traditional working relationships
promote attitudes such as,
"I will only do exactly what the
contract says", and
" I will get away with whatever I can
between partners’’ (McKim, 1995).
Quality management - just a paper?

The long-term performance of
any building and its ability to
satisfy clients’ requirements
depend both on decisions made
by its designers and on the care
taken and skill possessed by the
workers at the construction site
(Cheetham, 1993).

Engagement of Workers
Regarding faults caused by a lack of
engagement, the workers were responsible for
most faults, 70%, compared with the designers,
35% and the building site management, 42%.
This study shows that it is necessary to
combine an effective quality system with
increased information/training and measures to
improve the engagement of various parties in
the construction process.
Ref: Impact of Quality Management in the Swedish Construction Process

Impact of Design and Documentation
Quality
Poor design and documentation is the major cause of
construction process inefficiency, leading directly to
delay, rework and variations, and contributing to
increase of cost and project delivery time, for both
client and contractor.
Ref: CIB W55 & W65 Joint Triennial Symposium

Quality Management Objectives
Zero defect (no defects on each step, not just
handover)
Identify and solve problems without delay
Establish true quality control by making quality
“build in” and not “inspected in”.

COLLABORATIVE ENGINEERING
BY BIM

Integrated Project Delivery (IPD)
Integrated Project Delivery (IPD) is a project
delivery approach that integrates people,
systems, business structures and practices into
a process that collaboratively harnesses the
talents and insights of all participants to optimize
project results, increase value to the owner,
reduce waste, and maximize efficiency through
all phases of design, fabrication, and
construction. (http://ipd-ca.net/overview/)

Current Pains
Construction document are not accurate enough
Long hours spent on creating checklists in the office
Bad attitudes/abdication of responsibility / management
infallibility
Resistance of the workforce
Lack of proper training/inadequate human resource
development
Lack of effective measurement of quality improvement
No structured way to collect site inspection data
Time lost to digitize site data in the office after the visit to
generate reports
Poor follow up on visit non compliant items
Push management

Changes
By adopting the cloud computing with mobile
devices to enable self-disciplined real-time
construction QC/QA management that
significantly cut cost, improve productivity, and
improve the quality of projects.
