Whole cycle, one contractor
From excavation and the concrete shell through pipe installation, mechanical works and commissioning — all of it is our own crews. The client does not need a separate contractor to hold the interfaces together.
The company
AzHiLL Construction LLC
Main contractor in hydrotechnical construction. Baku, Azerbaijan.
2016 – 2026
From Dashkasan to the Upper Shirvan
The company started in 2016 with two contracts: a 3,000 m³/day treatment plant in Dashkasan and a 40,000 m³/day plant at Pirshaghi in Baku. The difference in scale was thirteenfold — and from the first year the team had to work both a small mountain site and a capital-city complex.
In the years that followed the portfolio widened from treatment plants into linear construction: after the Qazakh and Gadabay complexes came Aghdam's trunk collectors and the 10.4 km DN1600 steel main between Jeyranbatan and Atyali.
Today the principal work is on the Upper Shirvan Canal Project: the water intake structure and the tunnel complex. The two sites account for 73,000 m³ of concrete and 2,905 tonnes of reinforcement — more than all the company's earlier projects combined.

How we work
Three reasons we get the call
Large diameters
A DN1600 steel main, a Ø2000 reinforced-concrete storm collector, a Ø1400 CHDPE sewer — all laid and in service. At these diameters the plant, the lifting scheme and the weld control are nothing like an ordinary line.
Difficult sites
A mountain slope in Dashkasan and Gadabay, a city under reconstruction in Aghdam, riverside groundwater in Yevlakh. None of our sites has been a flat, dry field.
