Giving construction a new face with enhanced
project quality and reduced rework using BIM.
One of the most crucial challenges that have
affected the construction industry is Rework.
It has a direct impact on cost, time, quality,
people, and other criteria that facilitates
project success. Consequences of continuous
rework create considerable resource losses,
material waste, and stakeholder investment. The
adoption of meticulous designing and planning in
the presence and awareness of clients helps fuel
effective communication and utilization of
optimized systems. The elevated use of BIM on a
global level through various processes, tools,
and software has helped reduce project
inconsistencies and errors. This shift has helped
architects, engineers, contractors, owners, and
other stakeholders realize the full potential of
BIM. It has pushed project stakeholders to apply
TQM or Total Quality Management Models through
BIM.

• Managers need to identify the most influential
  components that can lead to rework and their
  effects on the project. A few factors that cause
  rework can be illustrated as follows.
• Design Errors
• Changes in client orders
• Poor project definition
• Insufficient project planning
• Weak communication leads to inefficient design

3

• Key processes,tools, and technology that can
  reduce project rework.
• Building Information Modeling (BIM)
• Lean construction techniques and tools
• Modular or prefabricated construction
• Project feasibility assessment
• Project construction and procurement based on
  effective communication and collaboration

Conclusion
In simplicity, Rework is defined as an
unnecessary effort of re-doing processes or
activities that were done or implemented
incorrectly in the first attempt. The cases of
rework include design errors, constant
construction changes, constructability errors,
and eliminating or expanding the scope of the
project. The effects of rework can be
significant, it has direct or indirect effects
on team and project performance.
5

• Direct effects of rework
• Time overruns
• Cost overruns
• Additional material for rework
• Cost of additional supervision
• Reduction in project quality
• Negative environmental impact

• Indirect effects of rework
• Profit reduction
• Shallow team morale
• Team conflicts
• Physical stress
• Mental exhaustion
• Loss of future opportunities

Significant factors that influence rework

• Nature of the construction project
• Inefficient material procurement
• Project complexity
• Lack of coordination between various stakeholders
• Poor communication between offsite and onsite
  teams
• Uncertainties due to weak information
• Client changes
• Delayed material delivery low material quality
• Defective construction
• Errors in design
• Lack of clear project scope and processes

7

• Primary solutions to reduce rework
• Effective use of project teams or workforce
• Adoption of new technologies to enable constant
  improvement
• Working on a client-centric model to reduce
  errors
• Assigning greater focus on the design process
• Managing project suppliers better
• Support project standards
• Total Quality Management
• Total Quality Management or TQM is a management
  technique that requires the participation of
  every stakeholder to drive quality. TQM works on
  the principle wherein profits follow quality. TQM
  is adopted in construction to achieve high
  project standards for complex buildings. The
  world of construction can cause delays and
  errors, and thus TQM is applied to construction
  for clear conception, better visualization,
  achieving project goals, and leverage
  productivity.

• Basic steps in implementing Total Quality
  Management (TQM).
• Build an approach towards TQM
• Need to achieve a quality commitment from the
  client
• Prepare a project quality plan at all project
  levels
• Take necessary steps to ensure continuous project
  improvement
• Measure and review quality plans and performance
• The need to adopt Total Quality Management (TQM).
• Lack of project records for experience,
  decisions, etc.
• Low project execution quality
• Lack of workplace necessities
• Lack of workforce participation
• Increase in construction cost due to rework
• Material waste in construction

• Striking benefits of Total Quality Management.
• Reduction in cost of quality
• Higher client satisfaction
• Lesser corrective work
• Reduction in project delays
• Better relationship with suppliers and
  sub-contractors
• Seven primary features of Total Quality
  Management (TQM).
• The commitment to efficient project management
• Perpetual attention to project teams and clients
• Efficient use of project workforce teamwork
• Continuous project improvement at various phases
• Consider material suppliers as project
  stakeholders
• Secure and control the quality
• Train the HR team

How BIM reduces rework and enhances quality
through TQM.

• As various project stakeholders like architects,
  designers, engineers, contractors, etc. have
  their points of view, it is important to build a
  shared aspect for project optimization is
  crucial. BIM enables complete and effective
  communication and collaboration between various
  stakeholders.
• Enhanced communication and collaboration help in
  the reduction of plans and document exchange
• It also improves the accuracy of content in these
  documents
• BIM quickens project design, execution, and
  processes in a virtual building landscape thereby
  delivering an accurate 3D model
• BIM models are parametric models that can be
  accessed anywhere, and anytime, and analyzed by
  various stakeholders. This improves the
  decision-making process
• With every piece of building information infused
  in a model, problems are detected and resolved
  before actual construction
• Based on TQM, a BIM model is the most credible
  source of information at various project stages
