Construction of Drinking Water Supply and Sanitation Schemes in Kohistan Upper

The Public Health Engineering Division Kohistan Upper is procuring construction services for multiple drinking water supply and sanitation schemes in the northern districts of Khyber Pakhtunkhwa, specifically for the district of Kohistan Upper. The tender covers six water supply schemes including Sayid Jan Chaki to Sabar Jamil Abad, Ajmira to Sigal Daman Abad, Berih to Chaman Abad & Shalkin Abad, Mangi to Bakhi Village, Komila City, and Sazeen Das with a combined estimated cost of approximately **PKR 141.817 million**. The technical scope involves comprehensive construction works for water supply and sanitation infrastructure, requiring contractors to manage site works, materials, and installation as per the detailed BOQs and specifications. The project demands experienced contractors registered with PEC for the fiscal year 2025-26, valid enlistment certificates from the Works Department, and registration with KPPRA and FBR. Bidders must submit technical and financial bids in a single envelope under the Single Stage Two Envelope procedure, with clear marking and accompanied by earnest money in the form of CDR at 2% of the bid cost. The tender submission deadline is **18-06-2026 at 12:05 PM**, with technical bids opening the same day at 1:05 PM. Clarifications can be sought until **11-06-2026 at 3:00 PM**. Bidders should ensure all mandatory documents including CNIC copies, audit reports, affidavits, and bank statements are attached to avoid disqualification. The submission must be made through EPADS and physically delivered to the Executive Engineer, PHE Division Kohistan Upper. A practical tip for bidders is to carefully prepare the financial bid with clear, accurate figures and avoid overwriting or discrepancies, as incomplete or inaccurate forms will be rejected. Also, contractors quoting bids more than 10% below the estimate must provide additional security, so financial planning should consider this to avoid bid rejection.
