CPM(Construction Progress Monitoring) is the term that plays a very vital role in the execution of any project in the construction industry. Basically, it’s a process of monitoring and tracking the execution progress of any project whether the progression is as per the pre-scheduled plan, and figuring out the issues or on-site challenges. So that immediate mitigation can be done or suggested to avoid time & cost overruns and to keep the progress on track.
Current execution process in construction
The construction industry has been following traditional practices in execution with very partial use of digital technology tools. Let's say, before starting any construction project, there would be a predetermined integrated schedule for each and every activity which is timelined with respect to the cost. Based on the schedule & sequence of the work processes will get kick-started.
So there will be an individual team to execute and to monitor the assigned task through physical observations, multiple site visits will be conducted by a specialized team, and on-site deployment.
All the issues are figured out by physical observations or methods and will be recorded manually.
Major challenges which are facing by the construction industry in the execution process
Coordination between the team & all the stakeholders.
Execution issues escalation & mitigation.
Transparency in the documentation of issue escalation & mitigation processes.
Construction Time overrun & Cost overrun.
As-Built verification & approvals.
Why is BIM required and the scope of BIM Implementation in CPM?
To bring a common platform between all the stakeholders, vendors & internal teams for proper coordination and information transfer. BIM implementation will bring the proper set of standards, where all the execution processes & issues escalation and mitigation can be digitized and documented.
BIM Methodology & Optimisation
The main theme is to bring a concept called BIM into construction progress monitoring to streamline the process of execution in a digital way by digitizing. This is where all the fragmented frameworks of different tasks will come to a common platform called CDE (Common Data Environment) and everyone will be aware of the current execution progress and the way it’s processed.
All the approved & revised sets of information will be updated in CDE, So that all the stakeholders, and vendors who all are associated with the project can get their required information without any delay.
A 3D-integrated (federated ) BIM model will be developed for better understanding in comparison to conceptual drawings. Initially, the LOD 300 model will be developed based on the design / Good For Construction (GFC) drawings. Later the model will be upgraded continuously based on the site's progress. All the changes which have been made or considered in the execution process will be incorporated into the model.
Basically, the 3D model will go under a progressive update as per site developments and later will be converted to the final replica of a fully executed building or an infrastructure project. This final replica of a project is what we call it as an As-built model (LOD500).
All the geometrical, nongeometrical & Asset information will be integrated to the 3D model.
As-Built verification using BIM processes
The verification process using the BIM methodology can be done in two different ways. One is for the buildings which are already constructed and under operation. Another one is for the buildings which are newly constructed and the BIM has been implemented in the construction process.
When it comes to projects where the BIM implementation has been done from end to end throughout the timeline, the final as-built model will be the replica of a construction project. This digital representation of the construction project is called Digital Twin.
With the help of BIM technologies, verification of a fully constructed site can be done using the As-built model. So, it’s an alternative process for on-site verification, surveys, multiple site visits, etc. All kinds of decision-making can be done by reference to the integrated BIM Model.
Benefits of BIM implementation in Construction progress monitoring
Federated 3D BIM Model with geometrical & non-geometrical data
Quick actions on-site challenges & immediate mitigations measures for the design issues before the execution starts
Transparency in documentation, execution process & in mitigation measures
proper coordination between the stakeholders/vendors
Pre-estimation of Time overrun & Cost overrun
Minimal On-site verification procedures, surveys, etc.
Easy As-Built verification using developed BIM models (As-Built)
BIM (Building Information Modeling) is a powerful technical tool that can be used for construction progress monitoring. BIM can provide real-time updates on the progress of construction projects, allowing stakeholders to track the project's status and make informed decisions. Top-level management can easily overcome the challenges of managing projects remotely.
