How Can BIM Teams Help with High-rise Building Design?

Modern construction projects have seen the scale of high-rise construction extend horizontally as well as vertically. Large high-rise projects can involve several multi-storey buildings qt the same location. Projects this large have complex requirements. Using BIM (Building Information Modelling) technology helps tackle these complex needs, making architectural BIM modelling, Revit 3D BIM modelling and other BIM services indispensable for high-rise building construction.

As high-rise buildings include both residential and commercial buildings, requirements may vary. Commercial and office spaces in high-rises need flexibility. Some parameters of high-rise buildings that require careful attention are:? ??

Structural Concerns?

• Must carry vertical gravity loads and lateral wind and earthquake loads?
• Needs adequate shear and bending resistance?
• Vertical load-carrying capability must be permanent, even during strong winds??
• Must withstand high pressure changes??
• Deflection, or sidesway at the top, must stay within a maximum value?
• Occupants must not perceive any swaying motion caused by vortex shedding.???

Foundations??

• High-rise foundations must support considerably heavy loads.????

Earthquake Loads??

• Must withstand energy released during earthquakes???

Structural Systems??

• Must fulfil lateral load performance criteria, using materials efficiently and within budgets? ?

Enclosure Systems??

• High wind pressures and vortex shedding effects need thick glazing in high-rises.???
• Large areas of enclosed surfaces means that thermal movements, wind and seismic-induced movements must be carefully considered.??
• Curtain walls must have fixed vertical tracks for window-washing platforms.???

???

Life-safety Systems??

• Must have generators for emergency lighting and fire pumps???
• Must have fire-suppression systems?
• A separate piping system can maintain water pressure and bring water to fire-hose cabinets in the building.??
• Exterior connections at street level must be included for portable fire-truck pumps. ??

Vertical Transport Systems?

• Escalators and elevators must be safe and planned carefully.????

Plumbing?

• Domestic water-supply systems need electric pumps and tanks to maintain pressure for all floors.??
• Water systems may be divided into zones, each with its own pump and tank.??

??HVAC

• Air-handling equipment may need centralised fans at every 20 floors or use fan rooms on each floor to provide air.???
• High-rises use limited centralised cooling systems.??

Extensive data must be collected, collated, calculated and communicated accurately during high-rise building design. By using BIM technology for all high-rise building design requirements, it may be possible to create near-flawless design.??

BIM Advantages???

Data Capture?

Data is collected, compiled and shared in a 3D model to accurately represent reality and streamline project processes.??

Minimise Wastage??

• A shared BIM model helps reduce rework and duplication of drawings for the many different requirements.
• The BIM model contains extensive data, allowing annotation and intelligent project connection.
• BIM drawing tools are fast.
• A vast database helps calculate quantity takeoff details, which are updated automatically as changes occur.
• BIM practices will ease complications and reduce errors while dealing with vast data.???

Keep Control??

Using autosave aids and connections in BIM-enabled software prevents sudden disappearances or corruption of files.??

Improved Collaboration

• Using BIM, sharing and collaborating is easy.
• Project management is delivered in the cloud, such as Autodesk’s BIM 360 Design solutions.
• Tools for different disciplines enable the sharing of complex project models and integrate data with project stakeholders.
• Review and markup steps mean that all stakeholders are aware of design evolution. ??

Simulation & Visualisation

• BIM-enabled software allows the simulation of sunlight in any part of a building at any time of the year or reflect the calculation of building energy performance.
• The software can analyse and model design concepts for optimum performance, incorporating data that can be used quickly and accurately.

???Resolve Clashes?

• BIM tools help detect and resolve clashes of elements, such as between electrical or MEP components, reducing costly on-site errors.??
• Using the model helps prefabricated elements fit together and be installed with minimum errors.??

Sequencing?

• Using a BIM model, steps, materials and crews can be sequenced easily and efficiently.? ?

Manage Details??

• BIM modelling helps share plans, sections, elevations and reports.??
• Automation and customisation features help save valuable drafting time.?? ??

Perfect Visualisation??

BIM modelling helps render impressive views and walk-throughs for commercial space sales or for approvals.???

Access Anywhere??

Connected to a database with cloud capability, models can be accessed from anywhere, on any device.????

Collaborate & Communicate??

When all project documents can be viewed by different project stakeholders, BIM teams can collaborate and communicate more effectively.????

In an environment that encourages BIM virtual construction, BIM services, such as architectural BIM modelling and Revit 3D BIM modelling, are imperative for high-rise projects. A BIM modelling services partner having the requisite Revit BIM knowhow can help deliver projects on time, of high quality and within budget.??

XS CAD has valuable experience providing BIM modelling services and BIM virtual construction services for general contractors and design consultants. Our range of services for building design firms across the world include architectural BIM modelling and Revit 3D BIM modelling services. We create these models and drawings by using Revit, AutoCAD and BIM 360 Design for cloud collaboration.
