Scope of Work: Reflections at Keppel Bay

Design, Engineering, Production, Procurement & Installation Package


PROJECT CHALLENGES


Key Project Challenges: Reflections at Keppel Bay

Design

§  Complex building geometry – Combination of convex, concave and slanted facade

§  Concave-convex facade - Maintaining horizontal plane for sill and head throughout the floor

§  Top hung window operation – weight & pull/push force

Operational

Collaboration

§  Finishes : glass types, cladding tones and anodized.

§  Installation methodology with regards to structural pre-camber

§  Collaboration with overseas Architects/ consultants

View perpendicular to glass Proposed solution to slim line mullion effect and simplified fabrication process

Complex Building Geometry


Adj. sill cover

Extended corner mullion cover (to cater for the differences in the depth &

angle of the facade)

Proposed solution to avoid differential panel leveling due to building geometry.

Adj. head cover

Solution to window operation.

Proposal of horizontal bar for ease of opening and closing operation

Gas spring was introduced as an “Anti slamming device’’ for safety reasons

•  Window Size: 43 in x 63 in (1108mm x1620mm) •  Glass Type : DGU •  Weight : 143 lb (65 kg) •  Window opening : 10 in (250 mm) •  Window opening force: 26 lb (12 kg)

Top Hung Window Operation


OPERATIONAL CHALLENGES


Design intent – 6 types of shades. 3 types of anodized panels with variation in anodized finishes were place horizontally & vertically to achieve 6 variation of shades.

Proposed solution to create 6 shades of anodized panels Finish Variation
