Building Envelope Works

In this building by Cesar Pelli, We designed, fabricated and installed the envelope formed by curved surfaces of the building. The curved envelope was made up of around 4 meter by 4.8 meter unitized aluminum panels, elements of which was produced and shipped knocked down for assembly by ZAHNER. The unitized panels were cladded by ceramic tiles substructure of which was designed by us and supplied by TERREAL. At parts of the curved envelope at their interference with the adjacent curtainwall we used SAPA profilesi as substructure. The three free leaf formed entrance canopies of the hospital were designed, fabricated and installed by us. Their smain structure was made of steel, leaf secondary structures resembling veins were made up of stainless steel. We designed special stainless steel adjustable spider glass supports to support all the unequal glass shapes, accommodate the various angles and shape differences of the glass. The spiders were produced for us by KIN-LONG. Rectangular shaped canopies were cladded with composite panels. Designed, fabricated and installed during my works in ALCE.

Emiri terminal is part of the Hamad International Airport which was solely for members of the royal family and state guests of Qatar. We installed the curved total vision glass with its vertical tension system, entrances, Interior decorated entrance facades and roof skylights of this building. Architecture is by ADPI. Installed during my works in ALCE.

Glass Dome Mosque is part of the Hamad International Airport located at autopark complex entrance/departure area. We installed the secondary structure, tdiagrid glass, suspended ceilinigs and flashings. Project Architecture is by Hellmuth Obata and Kassabaum. Installed during my works in ALCE.

Architecture is by Arup Associates. This job consists of perforated panel claddings with their primary and secondary substructures, vertical sandtrap louvers, air-vent funnels designed, fabricated and installed by us. Entrance glass facade materials are from SAPA, designed, fabricated and installed by us.

These stations are 3 sets of above grade stations in Foxhill neighborhood of Lusail. We undertook the design, supply and installation of the steel substructures, standing seam roofing system, ACP Wall Claddings, aluminum perforated ceilings and curtainwall facades along with Automatic Sliding doors. The curtainwall systems are from SAPA. Architecture by Lamela Cundall. Designed, fabricated and installed during my works in ALCE.

Architecture is by Lamela Cundall. These stations are 15 sets of above grade stations in Lusail. We undertook design, supply and installation of steel structure, GRC wall claddings, aluminium perforated ceilings, skylight parts, curtainwall facades along with automatic sliding doors. The curtainwall systems and skylights are from SAPA. Designed, fabricated and installed during my works in ALCE.

Architecture is by Nabil Gholam The job consists of interior cladding of two towers in the entertainment section. The towers are located at the ends of the rail path where an amusement train travels along, goes up and comes down vertically at the ends of the path. The interior is spanned with a steel diagrid supporting protective wire mesh and fabric concealing maintenance platforms, electro-mechanical installations. We undertook design, fabricating and installation of the secondary steel structure, mesh and polytetrafluoroethylene (PTFE) fabric cladding. Designed, fabricated and installed during my works in ALCE.

Architecture is by Ramboll and Pattern Design. We undertook design, supply and installation of Curtainwalls, all glass doors, louvers, internal glass partitions. The curtainwall system, frames of all glass doors and interior frames are from SAPA. Designed, fabricated and installed during my works in ALCE.

Architecture is by Henning Larsen. This building is constructed as slabs and columns with exterior walls made of diagrid steel structure, metal lining sheets, insulation and diagrid fitting rhomboid stones. The window and curtainwall openings also follow the diagrid shape, having rhombus forms. They project in or out, depending on the directions the facades face, fitting a pyramidal structure again covered with rhomboid stones. At the roof there are again pyramidal skylights to allow light to reach the interior parts. The above defined facade envelope and skylights were designed, manufactured, fabricated and installed by us. Curtainwall and skylight systems are from SAPA. Designed, fabricated and installed during my works in ALCE.

This building is at downtown area, Msheireb, of Doha, with an attractive form making it a focal point in the area. The envelope is made of curtainwalls, composite panels, spider system with total vision glazing. The building has a wide passage cut out within its mid from 1st to 6th floors allowing light to the inner parts of the building. The ceiling of the passage is cladded with mirror ACP to give extra depth and height illusion. In this passageway there is a total vision suspension system supported skylight. All of the mentioned works are designed, fabricated and installed by us. Curtainwall systems are from TECHNAL, total vision systems are from KIN-LONG Designed, fabricated and installed during my works in ALCE.

Pros of Diagrid structures is that they are one of the best solutions to cover irregular shapes. Cons is, because of the irregularity, the shapes of glass and panels over the diagrid become so varying and each being unique, they cannot be designed and manufactured without the help of 3D programs. We designed, manufactured and installed many envelopes similar to those structures shown in the above collection of photos. Designed, fabricated and installed during my works in ALCE.
