IMPLEMENTING PROJECT IMPLEMENTING PROJECT CONSTRUCTABILITYCONSTRUCTABILITYConstructability is the integration
of construction expertise into all phases of the project.
For Improving factors such as:cost schedule quality and overall project objectives.
IMPLEMENTING PROJECT IMPLEMENTING PROJECT CONSTRUCTABILITYCONSTRUCTABILITYThe proper use of the knowledge
gained by participants such as:managers designers site workersother contributors Learning from their past
experience increases the level of productivity/project success.
IMPLEMENTING PROJECT IMPLEMENTING PROJECT CONSTRUCTABILITYCONSTRUCTABILITYConstructability must be used at
key points in the project life cycle. This includes:
in the planning phase;early in the design phase; prior to the procurement phase;prior to the mobilization phase
for construction.
IMPLEMENTING PROJECT IMPLEMENTING PROJECT CONSTRUCTABILITYCONSTRUCTABILITYConstructability process
considers a detailed review of: Design drawings; Models; Specifications; and construction processes.
IMPLEMENTING PROJECT IMPLEMENTING PROJECT CONSTRUCTABILITYCONSTRUCTABILITY
The purpose of the constructability review
is to identify the following items:• Design errors (both material
selection or dimensions)• Un clear specifications• Unnecessary work• Complexity that does not serve
the project objectives
IMPLEMENTING PROJECT IMPLEMENTING PROJECT CONSTRUCTABILITYCONSTRUCTABILITY• Project features-difficult and
very costly to construct.• Project complexity- that
exceed the capability of industry to properly build.
• Project features that are difficult to interpret and will be hard to accurately bid.

required to ensure that controls of these processes are effective.
Ensure that the necessary resources, information necessary to support the operation are in place.
Make sure monitoring of these processes will be provided.
Set up systems to monitor measure and analyse the processes.

QUALITY MANAGEMENT QUALITY MANAGEMENT SYSTEM(QMS)SYSTEM(QMS)The construction industry has
embraced the ISO 9000 standard since its inception.
The QMS has become the benchmark for successful construction companies.
The QMS has also become the benchmarking for successful construction companies worldwide.
QUALITY MANAGEMENT QUALITY MANAGEMENT SYSTEM(QMS)SYSTEM(QMS)QMS has helped many companies to structure their management and processes to consistently meet the client’s requirements.
QUALITY MANAGEMENT QUALITY MANAGEMENT SYSTEM(QMS)SYSTEM(QMS)The eight Quality Management
Principles stated in ISO 9000:2000 and ISO 9004:2000 provide the basis for the performance improvement.

JIT & Quality Management JIT & Quality Management SystemsSystemsThe existing quality management
systems -ISO 9000 should include JIT.
It is practical to integrate ISO 9000 (20 clauses) with the 7 JIT concepts
Successful firms are using 7 concepts of JIT with ISO 9000 quality management systems in order to improve their productivity.
JIT & Quality Management JIT & Quality Management SystemsSystemsTo have high quality product and high
productivity is a challenging task for project management team.
All large construction companies have already established quality management systems within their organisation to meet ISO 9000 requirements.
Some companies are implementing the concepts of JIT and ISO 9000 separately.
JIT & Quality Management JIT & Quality Management SystemsSystemsBoth ISO 9000 and JIT objectives are: 1) high productivity 2) perfect product each time and
every time.ISO has no any clause related to
project time. It is a tool for productivity
improvement.

Cost savings derive from:Fewer delays.Fewer disruptions.Shortened duration of activities.Less work at higher elevations.Less material required.Decreased likelihood of labour
conflicts.
INTEGRATING CONSTRUCTABLITY INTEGRATING CONSTRUCTABLITY WITH QMS & JITWITH QMS & JITOne must initially invest to earn the costsavings from better constructability, suchas:More effort for design and procurement.More communication among builders,
designers, and the client.More communication among supply

Reducing the number of workers and costlier skills.
Better constructability methods can include:
• Prefabrication. • Economies and quality via
manufacturing process.
