Total Construction Quality Management by Leading ICT Technology

MTECH Engineering Co.,Ltd. 2016

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.

CONSTRUCTION QUALITY MANAGEMENT

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 relationshipspromote 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 WorkersRegarding 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 ObjectivesZero defect (no defects on each step, not just

handover)Identify and solve problems without delayEstablish 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.
