Design documentation for an alternative section of the Circular Collector
Preparation of comprehensive design and cost estimate documentation for the construction of a new sewer collector to replace an emergency-state section of the existing Circular Sewer Collector along R. Baghirov Street in the Khatai district of Baku using trenchless microtunneling techniques.
Scope of work and technical solutions:
• Hydraulic calculations and capacity modeling for the Ø1600 mm microtunnel collector;
• Plan-profile alignments and structural execution drawings adapted to urban constraints and soil conditions;
• Structural engineering of technological shafts (launching, reception, and inspection shafts);
• Design solutions for connecting existing basin carrier pipes into the new microtunnel;
• Surface settlement protection measures for road pavements, adjacent utilities, and structures;
• Complete bills of quantities, material specifications, and cost estimates.
