BIM (Building Information Modeling) in Plumbing
What is Plumbing?
Plumbing conveys fluids for a wide range of applications.
Uses pipes, valves, plumbing fixtures, tanks & other apparatuses to convey fluids.
Heating and cooling (HVAC), waste removal & potable water delivery are the most common uses for plumbing.
Major Categories of Plumbing System Potable Cold & Hot Tap Water Supply Plumbing Drainage Venting Sewage & Septic Systems with or without Hot Water Heat Recycling, Graywater Recovery & Treatment Systems Rainwater, Surface & Subsurface Water Drainage Fuel Gas Piping Hydronics Heating & Cooling Systems using water to transport thermal energy, as in district heating systems, like New York City steam system
Challenges of Plumbing during Building Process Starting from the stage of design & operation to maintenance, manpower is essential for constructing Plumbing System in the building sector, along with quantity estimation, coordination & scheduling. Different stages involve diverse expertise in executing the activities.
Further, a lot of problem crops up due to the lack of coordination.
Why BIM is Essential for Plumbing? Implementing BIM (Building Information Modeling) tec hnology before the project commencement, facilitates designers & engineers to make better decisions in the building process about plumbing system. In fact, BIM provides a comprehensive solution for designing, operation as well as maintenance.
A Brief about BIM • BIM (Building Information Modeling) entails a collaboration of different software applications, consisting of 3D, 4D, 5D, 6D & 7D in a single unit for project execution. • Using BIM services for plumbing, MEP Engineers can evaluate costs, estimate time, visualize design objectives, detect clashes and operate & maintain a plant. • Currently, BIM software is used by the AEC business professionals who are planning, designing, constructing, operating and maintaining diverse physical infrastructures, like water, gas and electricity. • The quality in building sector gets enhanced with BIM to meet the requisite of the building water supply & sanitation during the construction planning stage for better maintenance of the system.
Applications of BIM in Plumbing
3D Design Collaboration BIM Design Optimization Pipe Designing Parametric Families BIM Clash Detection 4D BIM Scheduling 5D BIM Cost Estimation 7D BIM Operation & Maintenance
3D Design Collaboration
BIM helps to create 3D building model for water supply & drainage design, containing all data like pipe size, material & type including soil pipe, cold pipe, slope & pump power.
The 3D BIM model can be updated automatically. If changes are made in one view, those can be automatically updated in all views.
BIM provides the opportunity to all AEC professionals to work simultaneously through a central system, thus reducing coordination issues and improving the workflow efficacy.
BIM Design Optimization
Design Optimization through BIM facilitates in resolving the problems in the traditional design. 3D building information data can be transmitted by intuitive BIM technology to achieve good transmission. In case of a certain degree of difference in the model design, the model can be divided on the basis of the floor & building water supply. Drainage design can be based as per civil & architectural engineering designs. Using BIM, other data can be automatically updated, and the system can be controlled in a convenient way.
Pipe Designing Water supply & drainage lines can be created easily with BIM technology.
BIM takes care of all the pipe fittings such as the tees and elbows according to the pipe network. The pipe slopes can be drawn as per specific inputs, mechanically analyzing the level, & hence time can be saved, compared to 2D drawing, calculating the slope and indicating the level. BIM also helps in assigning pipes with the right color codes in the application, eliminating incorrect pipe routing like placing of supply pipe instead of drainage pipe, leading to errors in quantification.
Parametric Families BIM includes readymade parametric families like water tank, urinals, water closet & other information like inlet, outlet dia, of pipe, pressure loss methodology & flow rate. The size & the dia of the pipe can be modified as per requirement.
Using 3D BIM Revit Parametric Model, a beginner can start designing easily & detect the issue at an earlier stage. The BIM application can also generate pressure loss reports, reducing the pressures at fittings owing to the coarseness of the material or other reasons.
BIM Clash Detection
Details of the clash report can be produced through BIM, after completion of all services in NavisWorks. MEP professionals can know the location with the grid coordinates through complete design & attach every point for design visualization at site. Clash free drawings produced from the 3D BIM Model help to reduce space constraints. Further, BIM helps in generating the reports & making changes to the model to make it clash free.
4D BIM Scheduling
Time estimation & scheduling is another positive aspect of BIM. 4D BIM helps in providing time estimation for the installation of plumbing service of the project, fed with the activities of the work to be done. The report can be connected in NavisWorks and the scheduling of the work to be executed can be prepared.
5D BIM Cost Estimation
The The 5D 5D BIM BIM Model Model contains detailed contains detailed information information to to execute the execute the essential essential task task as as per the per the budgeting. budgeting.
To To estimate estimate the the project budget, project budget, the the cost cost estimation estimation can can be be made made based based on on the the selected selected material material & & products. products.
5D 5D BIM BIM helps helps to to generate the cost generate the cost estimation estimation for for the the piping & pipe piping & pipe fitting. fitting.
With With a a single single click, click, quantities quantities can can be be generated and generated and the the cost cost can can be be applied for the applied for the quantities, quantities, giving giving accurate accurate estimation. estimation.
7D BIM Operation & Maintenance A single click on the equipment in the 7D BIM Model, helps to obtain information related to the Plumbing Operation & Maintenance. Schedule of the maintenance & activities can be executed with the selected equipment. System can be maintained with a steady upgradation of information about the condition of the system or equipment.
