BIM Drives Cost-Efficiencies for Plumbing Design

Since our construction industry is grappled with severe productivity issues and tight margins, the AEC industry is striving hard to come up with new ways of improving productivity, reducing construction costs and delivering a better-built building. Building Information Modeling, a new technological advancement in the AEC industry after CAD seems to have the potential to address these issues.

As per the definition of BIM by The National Building Information Model Standard (NBIMS), “BIM is a digital representation of physical and functional characteristics of a facility and it serves as a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life cycle from inception onward”. BIM has evolved from being just a buzzword to the centrepiece of AEC technology and it has significant benefits for plumbing design.

BIM enables a 3d virtual representation of the plumbing systems thus helping to better understand the final outcome, make more informed decisions and detect collisions. One of the major benefits BIM technology serves for plumbing is interference-checking. Using BIM to detect early collisions helps to prevent costly design changes during the actual construction process whilst also reducing guesswork and errors.

Since the underground plumbing lines are located in reference to the foundations; BIM enables a plumbing designer with actual building footings marked by the structural engineer to preserve the structural integrity of the building. With the help of the building footings, a plumbing designer can easily coordinate the underground routing without compromising the structural design of the building. 

Building Information Modeling is an ‘information’ rich model.  In addition to building shape, costs, design, construction time, physical performance, costs and logistics, BIM also provides information about two additional parameters in the case of plumbing fixtures – information about the required gpm flow of the standard fixture and the reduced gpm flow. 

With an aim to conserve energy and natural resources, there has been an increased focus on green building projects. BIM facilitates easier identification of systems in LEED Plumbing Design by creating different colour systems. Since there is a variation in colour, identifying grey water routing becomes easier and hence helps to prevent cross contamination with other waste systems.

BIM creates a unified working environment with multiple disciplines working together on a single file. A plumbing engineer can create a design for hot and cold water and simultaneously check the HVAC design worksheet for conflicts.

BIM serves a plethora of benefits for plumbing design such as increased efficiency, accuracy and coordination of the system as well as reducing the time and cost involved in it.

Green Buildings using BIM

With environmental concerns such as global warming, climate change and energy dependency increasing, promoting sustainability is the need of the hour. Everyone is trying to combat with these environmental concerns by going green and building sector is no exception. Building Information Modeling and Green building are the two new transformations seen by the construction industry that are fundamentally changing the approach towards design and construction. These two rising trends that have remarkable synergies could be merged together and wonders could be designed and constructed.        

The very term ‘Green Building’ means building that is environmentally considerate utilizing less water, efficient energy, generates less waste and conserves natural resources. Coming up with a green building would definitely increase the cost initially but in the long run, it will save money through lower operating costs over the life of the building.

Building Information Modelling is another new revolution in the construction industry that is gaining momentum. The main highlight of building information modelling services is the high-quality design information it provides. It can be used as a vital green design tool as this intelligent model also conveys information relating to thermal data, geographical position surface area and orientation. It helps to analyse various design options with its corresponding impacts on green building performances. Implementation of BIM helps to harness the characteristics and performance of design concepts, thus allowing sustainable alternatives to combat with conventional resources.

The potential of BIM in making green buildings has not yet been fully realised. In the coming years, the adoption of BIM in making green building would be substantially increased.
