BIM can open doors for a new era in the history of US Infrastructure. Here's how!
The pandemic has delayed or stalled several construction projects, owing to the shortage of materials such as structural steel and glass which are procured from Asia. Secondly, working remotely was also not an option for construction workers on site.
In the post-Covid
era, both pending as well as new construction projects are expected to come
with anticipated growth in the healthcare, commercial, and transportation
sectors. The residential projects are seeing an increased demand for
multi-family complexes.
President
Biden’s vision is to create a robust infrastructure that is safe,
environment-friendly and can withstand climate change. The allocation of over
USD 1 billion to ramp up the existing infrastructure - including railways,
bridges, ports, and highways – certainly fuels this ambition.
So, what
would the sector need to prepare itself for? Here’s an example from a public
sector renovation project scenario.
Traffic interruption during construction and repair poses a significant
challenge in
road and railway projects. For projects under renovation, add to it the
complexity of managing ground utilities like sewage lines, telephone cables,
water supply etc. This directly impacts
commuters and passengers who are taking the roadways, railways or airports, on a
daily basis. This interruption will need to be managed by project owners.
To avoid clashes during implementation leading to rework and project delays,
these nuances will need be to be factored in during the planning stage. Insufficient
contract management and lack of coordination between project stakeholders could
also lead to further delays and losses. BIM based project planning can remedy
all of this at once.
Though the AEC
industry in USA is one of the largest construction markets worldwide, it is
also fragmented in nature and had thus far, not really explored
technology-enablers or digital tools to enhance productivity. However, the
pandemic has introduced them to new possibilities. McKinsey, stated in a report
published in 2020, that designers and engineers are increasingly using Building Information
Management (BIM) to manage the projects and to speed up project execution
and delivery.
This incumbent
need for higher speed, scale and efficiency and the newfound interest for BIM
among construction companies is an invitation for adoption of BIM-based solutions. BIM is not new to construction firms in the USA.
It has been implemented since 1970s. What’s surprising though is the slow rate
of adoption. The lack of a single federal agency that can plan and mandate
BIM for all public projects, is perhaps one of the reasons responsible for
rather low adoption rates of BIM. The absence of a BIM mandate makes it
dependent on the association between construction firms, contractors, architects,
and other stakeholders, thus slowing down the process.
On the implementation
side, it is high time we think of BIM beyond its use as a design tool and
explore the depths of information that BIM models provide. BIM models can serve
as the single platform for resource planning and allocation, risk management,
material estimation and timely procurement, transparent and real-time
monitoring of progress, conflict-free construction within timelines, better
team collaboration, integration of safety and sustainability aspects and more.
A powerful
application of BIM modelling is in its
ability to gauge the impact of natural disasters on any asset. Such information
arms the project team in decision-making at early stages of the project, in
taking corrective action, and saving any additional costs incurred. In high
flood zone areas, using BIM model-based flood analysis and simulation can help
project teams to modify or redesign the project to avoid or minimize the
estimated impact of floods. Changing the elevation on the road can mitigate
risks in a flood-prone area, for example.
In effect, BIM can certainly be the fulcrum for building a robust, resource-efficient, and sustainable infrastructure in USA!
