Robin Partington & Partners Implements Federated BIM Worklfow to Design Westminster Borough’s Iconic Tower - 1

CASE STUDY Project Summary Organization: Robin Partington & Partners Solution: Buildings Location: London, United Kingdom Project Objective: • Deliver an iconic tower as the central focus of the GBP 500 million Merchant Square master plan. • Implement an integrated modeling approach to accommodate the complex, non-uniform, curved building profile while optimizing productivity and resources. • Design the various unique interior floor plans to complement the shell and core fabric of the dramatic structure. Products used: AECOsim Building Designer, Bentley Navigator, MicroStation®, GenerativeComponents® Robin Partington & Partners Implements Federated BIM Workflow to Design Westminster Borough's Iconic Tower AECOsim Building Designer and GenerativeComponents® Streamline Design Strategy for Complex, Curved Profile and Unique Interior Fitout Fast Facts • GenerativeComponents enabled RPP to rationalize the geometric form and cladding for the dramatic fagade. • Bentley Navigator and i-models were indispensable coordinating the basement design as well as the landscaping, drainage, and ventilation strategy. • AECOsim Building Designer enabled RPP to build an intelligent model of 1 Merchant Square with enough building data to run a 4D construction sequence. Bentley software facilitated an integrated BIM workflow minimizing requests for information and potential construction issues. GenerativeComponents saved project resources by enabling the team to produce numerous cladding iterations in a fraction of the time it would have taken using basic 3D modeling. Using the AECOsim Building Designer model enabled RPP to develop a trapezoidal unitized frame while maintaining rectilinear glass, which represented approximately 40 percent savings in terms of glass cost across the project. A New Hub in Paddington The GPB 500 million Merchant Square development brings together four buildings and their unique setting as one coherent piece of urban infrastructure in the heart of Paddington, London, United Kingdom. In order to transform the area into a landmark destination, European Land and Property appointed Robin Partington & Partners (RPP) to design a master plan consisting of three phases of development. The first, which has reached completion and includes 3 Merchant Square and a portion of the basement, had to function independently for a number of years before the second phase of the project began. Phase two, the current phase of development, includes buildings 1 and 6 Merchant Square, and the completion of the basement, including the landscaping, drainage, and ventilation strategy. The final phase will see the completion of 2 Merchant Square. While RPP faced numerous logistical challenges including the completed adjacent buildings, 4 and 5 Merchant Square, adjacent basement piling and structure, as well as the canal, designing 1 Merchant Square presented its own set of unique demands. RPP relied on the interoperability of Bentley's 3D design software to implement a federated BIM strategy and deliver the complex, curved tower. Forming the 42-story, Mixed-use Tower With a 93-key boutique hotel at its base, 209 apartments with private balconies above, and a spectacular two-story Skybar offering 360-degree views of the city of London, 1 Merchant Square will set a new standard for residential accommodation in Paddington. RPP wanted to develop the form of the building to fit within the master plan, yet be seen as a focal point and urban marker for the wider area. "We used AECOsim Building Designer to develop the form of the building and went through a series of iterations trying to develop the most elegant form whilst optimizing the client's brief in terms of area," explained James Ewen, Project Leader and Partner at Robin Partington & Partners. RPP developed the sleek, curved building form with vertical structural fins clad in white porcelain, a midnight blue ceramic rainscreen cladding, and a distinctive crown-like peak. While the curved shape helps minimize the effects of wind, the geometry of the building necessitates trapezoidal cladding panels as opposed to the standard rectangular shape. The project team created the model in AECOsim Building Designer based on a 72-point-spaced coordinate system to help understand the building frame and analyze and accommodate the increasing trapezoidal panel shapes toward the extremities of the tower. Stated Ewen, the use of the model and careful detailing enabled RPP to "develop a trapezoidal unitized frame while maintaining rectilinear glass, which represented approximately 40 percent savings in terms of glass cost across the project." With a 93-key boutique hotel at its base, 209 apartments above, and a Skybar on top, 1 Merchant Square will set a new standard for residential accommodation in Paddington. Computational Modeling Streamlines Design Designing a building with varying cladding bay types presented RPP with the challenge of matching exterior finishes to the changing internal layout throughout the tower. With each bay type comprising a different arrangement relative to the internal layout, RPP realized that modeling all scenarios for the 150-meter structure would take a considerable amount of time.
