Vertical Transportation & Façade Access Consultancy for New York Architects, Engineering Consultants & Design Teams

Supporting New York-Based Architects, MEP Consultants and Multidisciplinary Design Teams Delivering Major Projects Across the Middle East, India & International Markets

Dunbar & Boardman (D&B) is an independent Vertical Transportation consultant specialising in lift and escalator consultancy, lift traffic analysis and simulation, high-rise Vertical Transportation design, BIM coordination and Façade Access consultancy.

D&B supports New York-based architects, MEP consultants, building-services consultants, engineering practices, master planners and multidisciplinary design teams delivering complex developments across the Middle East, India and international markets.

D&B also supports architects, MEP consultants, engineering practices and multidisciplinary design teams based in other major U.S. design and engineering centres, including Chicago and Washington DC, particularly where their commissions extend to projects across the Middle East and India.

Established in the United Kingdom in 1981, D&B brings more than four decades of specialist consultancy experience, together with established regional delivery capability across the UAE, Saudi Arabia, the wider GCC and India.

For U.S.-based design and engineering practices working internationally, D&B can provide specialist Vertical Transportation (VT) and Façade Access expertise from early-stage concept planning, high-rise core development and lift traffic analysis through detailed design, BIM coordination, procurement, construction, testing and commissioning.

Supporting New York's International Design & Engineering Community

New York is one of the world’s leading centres for architecture, engineering, high-rise design and multidisciplinary consultancy, with New York-based practices contributing to major commercial, mixed-use, hospitality, residential, cultural, aviation and destination developments internationally.

D&B works collaboratively with international design teams, providing specialist expertise that can be integrated into the wider architectural, MEP and engineering design process.

For complex and high-rise buildings in particular, early Vertical Transportation input can significantly influence building-core efficiency, lift zoning, passenger circulation, floor populations, system capacity, equipment configuration and overall development efficiency.

Our early involvement allows these requirements to be assessed while the architectural concept and building core remain flexible, helping design teams balance passenger performance, operational requirements, spatial efficiency and capital investment.

Whether appointed directly by the client or engaged as a specialist subconsultant to an architect, MEP consultant or multidisciplinary engineering practice, D&B provides independent specialist support from concept through project delivery.

D&B works with MEP, building-services and multidisciplinary engineering consultants requiring specialist Vertical Transportation or Façade Access capability as part of their wider international design commissions.

Where these specialist disciplines are not maintained in-house, D&B can integrate with the consultant’s project team as a specialist VT and Façade Access subconsultant, providing dedicated technical expertise while supporting the lead consultant’s overall design and delivery responsibilities.

Our specialist support can include:

Vertical Transportation strategy and system planning
Lift traffic analysis and simulation
Lift population, zoning, capacity and speed studies

Flexible Specialist Subconsultancy

Specialist Subconsultancy Appointments

D&B can be appointed by architects, MEP consultants and multidisciplinary engineering practices to deliver specialist VT and/or Façade Access packages within their wider international design commissions. This enables the lead consultant to access specialist capability without the requirement to maintain dedicated VT or Façade Access resources in-house.

Project-Specific Technical Support

D&B can undertake a complete specialist consultancy scope or provide targeted input for individual project stages, including traffic studies, high-rise core reviews, design reviews, BIM coordination, peer reviews and specialist technical assessments.

Framework & Portfolio Support

For international consultants delivering multiple projects across the Middle East and India, D&B can provide ongoing specialist VT and Façade Access support across a portfolio of projects.

This can provide consistency in technical standards, design methodology, documentation and specialist resources across multiple commissions.

Peer Review & Technical Advisory

D&B can provide independent technical review and specialist advisory services where an additional level of VT or Façade Access expertise is required.

Independent Vertical Transportation Expertise

High-Rise VT Strategy & Core Planning

For high-rise and complex developments, Vertical Transportation strategy is a fundamental component of building planning.

D&B develops VT strategies considering:

Building population and occupancy
Lift zoning
Sky-lobby strategies where appropriate
Passenger and service lift requirements
Lift capacities and speeds
Destination-control systems
Core configuration and efficiency
Service and goods movement
Mixed-use segregation
Firefighting and evacuation requirements
Equipment spatial requirements
Operational performance

Early specialist involvement allows alternative VT strategies to be evaluated before the building core becomes fixed.

Lift Traffic Analysis & Simulation

D&B undertakes detailed lift traffic analysis and simulation to evaluate passenger demand, handling capacity, waiting times and overall system performance.

Studies can consider:

Morning up-peak traffic
Inter-floor and lunchtime traffic
Evening down-peak traffic
Commercial office populations
Residential traffic patterns
Hotel guest and service movements
Mixed-use traffic segregation
Destination-control systems
High-rise zoning strategies
Lift capacity and speed optimisation

For high-rise and mixed-use developments, traffic analysis can be used iteratively with architectural core planning to evaluate different lift configurations and identify an appropriate balance between passenger performance and usable floor area.

Lift, Escalator & Moving Walkway Design

D&B provides independent planning and technical design for passenger lifts, service lifts, goods lifts, escalators and moving walkways, appropriate to the building type, anticipated population, operational requirements and project design criteria.

Our independent position allows equipment strategies to be developed around the requirements of the building rather than around a particular manufacturer’s product range.

Design Development & Technical Documentation

Our services extend through schematic and detailed design and can include:

VT design criteria
Lift and escalator schedules
Technical specifications
Shaft and pit requirements
Machine-room requirements where applicable
Architectural interfaces
Structural interfaces
MEP interfaces
Builder’s-work information
Tender documentation
Technical design reports

D&B can coordinate its specialist deliverables with the wider architectural and engineering documentation package.

BIM & Digital Coordination

D&B provides BIM-enabled Vertical Transportation coordination, including LOD 300 modelling, architectural and MEP interface coordination, clash review and collaboration through Common Data Environment platforms.

For international projects involving design teams located across multiple countries, digital coordination enables D&B to work effectively as part of the wider project team irrespective of geographical location. Our BIM capability supports the coordination of lift shafts, pits, headroom, machine spaces, equipment interfaces and associated architectural, structural and MEP requirements.

Tendering, Construction & Commissioning

D&B’s involvement can continue beyond design through:

Tender technical support
Technical bid evaluation
Contractor design review
Shop-drawing review
Equipment submittal review
Architectural and MEP interface review
Construction-stage coordination
Site technical support
Testing and commissioning advisory
Handover support

This provides continuity of specialist VT advice from the initial design concept through project completion.
