Oman's summer midday work ban: 12:30–15:30, June to August, and how to programme around it

Under Ministerial Resolution No. 286, work on construction sites and in open spaces must stop between 12:30pm and 3:30pm throughout June, July and August. The measure is intended to protect outdoor workers from extreme heat and heat-related illness.

Non-compliance carries penalties reported at no less than RO 500 and no more than RO 1,000, with inspections carried out at construction zones and outdoor sites during the restricted hours. Certain sectors — airport operations, port activities and emergency utility services among them — may operate during the restricted window, but only with prior approval.

Guidance encourages shifting heavy labour to cooler parts of the day, providing air-conditioned rest areas, and using rotation patterns such as 45 minutes of work followed by a 15-minute break.

None of that is exotic. What separates sites that absorb the ban from sites that lose weeks to it is whether the shift pattern, the welfare facilities and the delivery schedule were designed for it in advance.

Three hours a day across roughly 65 working days is a material chunk of a summer programme. If your baseline programme assumes a flat productivity rate across the year, it is wrong, and the variance will surface as a delay claim.

Practical steps: build a summer productivity factor into the baseline rather than a blanket contingency; move concrete pours, steel erection and external works into early-morning and late-afternoon windows; front-load internal and enclosed works into the summer months where the sequence allows; and align material deliveries so plant is not idle across the restricted window.
