Challenges faced by constructionprofessionals
with conventional methods of construction

• Lack of coordination
• Lack of sequence
• Lack of clarity of roles
• Site disturbances
• Greater material waste
• Time and labor wastage
• Delayed schedules
• Unsafe construction
• Higher costs

• Contractors, architects, site engineers
• MEP contractors
• Prefabrication firms
• Construction companies

4

• Projects can be completed 35 to 55 quicker with
  BIM-based prefabricated and modular construction.

5

• Prefabrication drives greater construction ROI
  with integrated BIM

Minimized construction waste saves cost
the challenge

• Greater material waste with traditional
  construction
• Fabrication errors with inaccurate and incomplete
  2D drawings

the solution

• Accurate 3D model-based shop drawings reduce
  manufacturing waste and reduce rework
• Advanced tools integrated with BIM enable
  contractors to visualize project scope, material
  costs, etc.
• The elements with typical size can be filtered
  with BIM model to help overall savings of cost

Better quality control
the challenge

• Components manufactured onsite may be of
  low-quality due to incorrect usage or damage
• Weather conditions deteriorate the material
  quality reducing construction quality
• Exposed project sites can lead to material theft
  

the solution

• Manufacturing components in an offsite controlled
  environment drives high-quality with LOD 400 BIM
  models
• Large batches of replicated products with 21 days
  curing and controlled temperature, moisture,
  wind, atmospheric pressure improve productivity
• Offsite prefabrication factories are secure,
  cancelling out material thieving

Minimum site disruption
3
the challenge

• Onsite fabrication of building materials can
  disrupt traffic around the project site
• Use of heavy machinery and frequent material
  movements produce plenty of noise
• Storing material onsite requires additional space
  which is very rare

the solution

• Offsite prefabrication cancels out site
  disruption through seamless logistics
• Minimal use of machinery, materials, and labor
  cancels out site noise
• BIM-based models have unique numbers assigned to
  components for easier onsite assembly and
  installation

Better construction schedules reduce delays
4
the challenge

• Flawed quantity takeoffs with inaccurate
  CAD-based drawings
• Inaccurate fabrication and installation schedules
  
• Coordination issues and inaccurate material
  logistics

the solution

• Prefabricated components take less time to build
• BIM based scheduling is accurate as compared to
  traditional construction and diminishes schedule
  delays
• BIM enabled fabrication and installation is quick
  and reduces project costs

Flexibility, reusability, and safety with reduced
onsite risks
5
the challenge

• Traditional fabricated components are not
  flexible and reusable
• Limited design opportunities do not work with
  external aesthetics
• Onsite construction teams face greater risks of
  accidental hazards with onsite fabrication

the solution

• Prefabricated or modular components are better
  engineered for flexibility, reuse, and
  performance
• Multiple design prototypes using BIM can
  integrate prefabricated units to match the
  aesthetics of buildings
• Offsite prefabrication lowers onsite risks caused
  by accidents and liabilities
