BUILDING IT TWICE
FIRST VIRTUALLY THEN ON-SITE!
We build your project first virtually, along with 3D modeling every component using BIM and clash detection technology. Let us see how clash detection technology helps us identify any clashes/errors in the project before On-site execution, resulting in Error-Free construction.
WHAT IS CLASH DETECTION?
Clash Detection is a part of the Building Information Modeling (BIM) process wherein experts like contractors, sub-contractors, architects, project workers, sub-workers, and so on, can distinguish the conflicts in the construction cycle early on, and resolve them in the pre-construction phase.
For this, a 3D BIM Model proves to be of great help in resolving conflicts in no time through a computerized approach so that there could be potential
time, money, manpower, and resource-saving during that actual construction.
WHAT DO CLASHES LOOK LIKE ON-SITE?
Clash 1: Missing punch-outs for passing services in structural members might cause
drilling of the member on site. An inexperienced worker who is unaware of basic code
appliances might cause damage to the member or the whole panel.
Clash 2: Unexpected ceiling drops to accommodate HVAC Ducting- Because of the
ceiling's clear height, services or circulations often clash with the ceiling framing or
Clash 3: When you try to place a slab on a set of walls that do not make contact with
Clash 4: Air-conditioning duct running through a load-bearing wall.
Clash 5: MEP components like air conditioning units, heaters, etc. have a common buffer
Clash 6: The size of the door is larger than the opening span in the framing.
Clash 7: Pipework having a clash with a beam.
WHY CLASH DETECTION IS IMPORTANT?
Clash detection aids in effectively identifying, inspecting, and reporting errors/conflicts between two or more trades in a construction project model.
It’s useful in checking work status and wanes down human errors during model inspections.
Clash detection is important because it integrates several models (structural, MEP, etc.) into a single BIM model. With the clash detection feature, faults that conventionally were detected on the site and involved high cost and schedule implications, are corrected at the design stage.
DID YOU KNOW?
According to a McKinsey report, rework in construction accounts for almost 30% of overall construction cost in a typical project, and 98% of megaprojects overshoot their budgets by at least 30%, while 77% projects are 40% late in construction schedule.
PROCESS OF CLASH DETECTION AND RESOLUTION
GENERATE INDIVIDUAL MODELS
Individual models are generated
like Architectural, MEP, structural,
Individual models are overlapped
in a single 3D model to see how
elements are using space.
RUN CLASH DETECTION
Run the clash detection test on the
linked model to trace if any errors
or clashes exists in the model.
Clashes are identified and
reports are generated
The generated report is sent to
the concerned trade engineers.
Once all the clashes are
corrected the model is reuploaded
on the software.
The corrections are made and a
re-run of the model is done to
identity any further clashes.
This final set + model helps us in
generating a full blown detailed
sheet that outline where each
element will be.
Smooth sailing of the project.
Lesser RFIs and no time wasted on-site.
REDUCED COST OVERRUN
While it depends on the circumstances, a clash or conflict found during construction can cost thousands of dollars and weeks of the project schedule depending on the nature of the clash and at what stage of the process it is found.
By using clash detection we can completely eliminate the risk of cost of construction going beyond the estimated cost.
DID YOU KNOW?
The Barlish and Sullivan study, which looked at 5 commercial projects, reported an average of 42% reduction in the cost of COs (Change Orders), 50% reduction in RFIs (Request for Information), and 5% reduction in overall project cost, making a strong case to justify the investment in BIM modeling with clash detection.
Clash Detection helps eliminate delays in construction due to disputes between the design and execution phases.
Because of 3D modeling and Clash detection one can have real-time visuals of their project, can identify any errors/conflicts, and make necessary changes virtually, minimizing delay due to several change orders on-site, making the construction process faster without room for any on-site error.
BETTER CO-ORDINATION BETWEEN TRADES
The use of a Clash detection procedure allows project teams to easily share information.
Clash detection ensures quick knowledge transfer and efficient coordination between members of various trades of the construction process, engineering, and design.
MINIMIZED CHANGE ORDERS
When everything is planned, visualized, and managed using Clash Detection during the design stage itself, it prevents the occurrence of change orders during the construction phase.
As everything is examined as a 3D model, distinguishing clashes gets simpler, eliminating making changes on-site, and resolving issues at the planning phase.
IMPROVED QUALITY-WITH NO BAND-AIDS
Clash detection helps reduction in changes during the construction phase. Imagine while constructing on-site, it comes to notice that a duct is passing through the top of a door or an exhaust at the top of a window causing a clash with its header. This will eventually end up with modifying the Door or window opening, and changing of sill height, leading to modification of the structure. Therefore it’s always better to check & modify everything early in the design process.
As less rework on site will help Band-Aid Free construction, it will ultimately contribute to keeping the construction quality intact.
Many times construction is delayed owing to a lack of coordination, lack of positive communication between teams, and errors while implementing the project.
Use of Clash Detection helps the Delivery of the project on time as it contributes to the detection of clashes before the construction phase, resulting in execution as per the planning and scheduling.
