Notes from the site and the plant room

Practical notes on structural steel erection and chiller maintenance in the UAE, written by the AL NIMRA team.

Structural steel

Temporary works and stability during erection

A frame is at its most vulnerable while it is going up. Stability in that condition is designed, not judged on site.

Documentation that should survive the project

The building will outlive everyone who worked on it. What it needs from them is a record.

Chiller commissioning: what should be witnessed and recorded

Commissioning is where the baseline for the machine's whole life is set. What gets written down is what you can hold anyone to later.

Refrigerant handling and why it is regulated

Refrigerant is a controlled substance, an operating cost and a leak-detection problem, in roughly that order of consequence.

Reading a structural steel drawing

Grids, marks and revisions. Enough to follow a steel drawing and know when you are looking at the wrong one.

Planning a chiller replacement in an occupied building

The plant is the straightforward part. Access, temporary cooling and sequencing are what decide whether the job goes well.

Energy efficiency measures that actually pay back

Cooling dominates the electricity bill here. The cheapest savings are usually in how existing plant is operated.
