Facade Engineering
Our core expertise, facade engineering consultancy gives solutions on well performing, structurally sound building envelopes.
Facade Access
All areas of the facade shall be accessed for cleaning and maintainance. We specify working, optimal facade access strategies.
Specialist Engineering
Exposed architectural steelwork, structural glass features, building physics. To ensure that everything looks nice and works well.
Complex Geometry
Not all buildings are rectilinear. Optimisation of curved, inclined, warped, free form geometries and solutions to realize them.
Large Scale Projects
Our team is experienced in delivery of facade packages for large developments, supertall buildings, mixed used towers.
Value Engineering
VE for us is an ongoing approach, we constantly monitor our design for effciency, cost optimization, ease of fabrication.

Why do buildings need well engineered skin?
Facade Engineering is a unique discipline, combining architecture, structural engineerig and building physics. The tasks a facade engineer carries out at different stages ensures that the client's vision manifests in an end product the most optimal and efficient way, within reasonably agreed time frame and budget.
First imperession counts
Well detailed, well executed building facades complete the architectural design intent. Browse our Projects page to see the variety of facade designs we carried out, using a range of materials such as glass, metal, stone, glass reinforced concrete, pre-cast concrete; and a variety of systems such as stick and unitized curtain walling, rainscreen cladding system, sandwich panel and layered build-ups. We also develop and engineer structural glass projects and special enclosures. We understand the architectural design process well and use our technical experience to simplify, enable or even push technical limits for to create good architecture.
Performance is important
Good building envelopes are air- and water-tight, thermally insulating, protect from solar heat, let natural light in, reduces noise, does not propagate fire. The key here is correct selection of several components: materials, system concept, interface details; with consideration of climate, orientation, durability, safety. All of our building rate high on energy conservation, some with Sustainability Rating awards. See the News section for latest performance tests, awards and ackonwledgments.
Structural safety is a must
Building skins shall withstand earthquakes, windstorms, tropical rain, subzero freeze, without loss of performance and cater for regular base building movements by design. Pre-engieering the facade system even before the contractor is appointed allows for more accurate budget estimate.

How we work?
Typically, we get involved in early schematic stage, appointed by the developer, the lead consultant, or the architect.
- Design stages: system concept development,advice on materials, preparation of details and specifications
- Tender stage: technical evaluation of bidders
- Construction stage: review of the contractor's submittals, site inspections, test witnessing
We may also work for facade contractors, providing calculations and system design on engineering demanding structures and parts of buiding envelopes.
We can also work with main contractors, project managers, facility managers, on specialists facades related tasks.
