3.2 km collector road opened three weeks early with 58,000 m³ of earthworks in 13 weeks.
The challenge
A 3.2 km collector road linking an industrial cluster to the regional highway crossed soft wadi deposits and had to open before a logistics operator took possession of the adjoining plot. Material haul was 300 km each way, winter night temperatures in Ha’il dropped below 10°C, and a wadi crossing needed scour protection sized for flash floods.
Our approach
Subgrade was undercut 1.2 m through the wadi deposits and replaced with geotextile-separated select fill, plate-load verified. Base course came from a nominated quarry with monthly gradation checks, and asphalt paving ran in daytime-only windows with night compaction prohibited below 12°C surface temperature. The wadi cross-drain and rip-rap scour protection were completed before the first winter rain, and traffic was switched onto the new road for the final 800 m tie-in.
The result
Thirteen weeks — three weeks inside programme: 3.2 km opened, 58,000 m³ moved, all density and ride tests passed, zero lost-time injuries across 21,200 safe man-hours at a peak crew of 32.
