Written on three contracts, the scope reads almost identically: aluminum and cladding works. What that sentence actually requires changes with where the building stands and what happens inside it.
Dammam: the coast
Arkan Square Mall is a retail envelope in Dammam, and Dammam is on the Gulf. Salt-laden air is the condition that governs everything on a coastal facade: the grade and coating of the aluminum, the metal used for every fixing behind the panel where nobody will ever look again, and the assumption that anything which can corrode, will.
The second condition is retail itself. A mall is glazed because it is selling what is behind the glass, so the elevation is mostly transparent and curved rather than flat — and a curve is where a cladding system stops being a repeated panel and starts being a set of individually measured ones.
Riyadh: heat, dust and an entrance
Maharah Human Resources is a corporate headquarters: aluminum systems and cladding, with a glazed arched entrance. Inland, the governing conditions are heat and dust rather than salt — a much wider daily temperature swing for the facade to move through, and fine dust that finds any gasket that was not seated properly.
The arch is the other half of the job. A curve in an entrance is the part of a building that everyone walks through and everyone looks at, and it is the part least forgiving of a few millimetres. It is set out, fabricated and fitted as a single piece of work rather than as an opening in an elevation.
The same scope of work, in three places, is three different jobs.
Al-Qassim: a working hospital
The Gulf Housing Complexes Hospital is again aluminum and cladding — but a hospital is a building that cannot stop. The facade is not the difficult part; access, sequence and cleanliness are. Work is staged so that what is behind the elevation stays usable, and the site is left each day in a state a hospital can accept.
What the three have in common
Not a material and not a system. What they share is that the envelope was engineered, fabricated and installed by one accountable team, so that the answer to a coastal fixing, an arched entrance or a ward that must keep working was decided once — by the people who would have to live with it.
