Request for Empanelment for PQC Repair and Replacement, RCC Structure Repair Works, and Related Miscellaneous Works for the Comprehensive Rectification and Rehabilitation of the Raipur-Simga and Simga-Bilaspur Sections of NH-130 (Old NH-200) from Km 0.000 to Km 48.580 & Km 48.580 to Km 126.525 in the state of Chhattisgarh under NSPPL.

Dismantling of pavement quality concrete (PQC) in existing panels, ensuring minimal disturbance to adjoining panels by using precision equipment such as jackhammers, handheld concrete saws, or low-impact concrete splitters. The PQC must be broken into small pieces, sized appropriately for ease of handling and transport, with pieces suitable for potential reuse in debris filling applications at approved locations. All dismantled material shall be loaded, transported, and disposed of within a lead of 1 km from the worksite. Any serviceable materials such as embedded steel bars encountered during the dismantling shall be carefully removed, cleaned, and stacked separately for potential reuse or disposal as directed by the Engineer-in-Charge. The rate includes the cost of all labor, equipment, transportation, stacking, and any incidental works. Cost Inclusions: The final price covers all expenses for equipment usage, labor, transportation up to the specified lead distance, material handling, and stacking of serviceable steel, as well as any incidental costs. Relevant Specifications: This work should comply with relevant MoRTH and IRC standards for dismantling and debris management to ensure safety and efficient waste handling practices.

Cement Concrete Pavement (Construction of un-reinforced, dowel jointed, plain cement concrete pavement over a prepared sub base with 43 grade cement @ 400 kg per cum, coarse and fine aggregate conforming to IS 383, maximum size of coarse aggregate not exceeding 25 mm, mixed in a batching and mixing plant as per approved mix design, transported to site, laid with a fixed form or slip form paver or Mannual spread, compacted and finished in a continuous operation including provision of contraction, expansion, construction and longitudinal joints, joint filler, separation membrane, , admixtures as approved, curing compound, finishing to lines and grades as per drawing)

Dowel Bar- All charges for providing, cutting, bending, transporting, and tying of Dowel bar steel of designation FE 500 as per IS 1786 for Rigid Pavement construction work. The vendor shall supply all necessary steel and Dowel Bar Caps. Dowel bars are to be cut & fix as per approved drawings, ensuring precise dimensions and placements. Dowel bars shall be securely fix with provided chair as per Morth Specification. No separate payment for chair to be considered. Steel will be measured by weight in kilograms, excluding chair & binding wire and without allowances for overlaps or wastage. The scope of work includes supply, handling, and on-site quality assurance for positioning, alignment, and compliance with specifications and as directed by EIC. Safety measures and quality checks shall be implemented during all stages, ensuring high-standard reinforcement for structural integrity. Reinforcement bars from the approved make shall only be used.

Tie Bar- All charges for providing, cutting, bending, transporting, and tying of Tie bar steel of designation FE 500 as per IS 1786 for Rigid Pavement construction work. The vendor shall supply all necessary steel . bars are to be cut & fix as per approved drawings, ensuring precise dimensions and placements. Tie bars shall be securely fix with provided chair as per Morth Specification. No separate payment for chair to be considered. Steel will be measured by weight in kilograms, excluding chair & binding wire and without allowances for overlaps or wastage. The scope of work includes supply, handling, and on-site quality assurance for positioning, alignment, and compliance with specifications and as directed by EIC. Safety measures and quality checks shall be implemented during all stages, ensuring high-standard reinforcement for structural integrity. Reinforcement bars from the approved make shall only be used.

Repair of old Joints Sealant (Removal of existing sealant and re sealing of contraction, longitudinal or expansion joints in concrete pavement with fresh sealant material) as directed by Engineer-In-Charge

Repair of Cracked Rigid Pavement (PQC Panels) using Cross bar stitching : Crack stitching with inclined tie bar (cross Stitching) used for cracks in reasonably good condition in order to arrest movement of slab and slabs pieces by making primer verticals holes,, alternative inclined hole, cleaning the hole through oil free compressor and filled with epoxy resin in enough quality that will coat HYSD bar confirming IS 1786 of 12 mm dia in every hole also groone shall be made along with line cracks display spalling and filled with a low viscocity resin or fire epoxy mortar following the method specified IRC SP 83:2008.

Repair of Cracked Rigid Pavement (PQC Panels) using Stapling : Stapling used to provide positive mechanical interconnection at longitudinal crack or joint between two slabs or segments. 16 to 20 mm dia epoxy coated U-shaped deformed bars placed in the slots hold the segment together, serving to maintain aggregate interlock and provide added reinforcement and strength.

Crack Sealing: Providing and laying low viscosity, abrasion resistant, insitu UV resistant sealer FOSROC EP75 / equlavant into all type of concrete pavement cracks wherever required in culverts, bridges and pavements as per manufacturer’s specifications and guidelines etc. complete including chipping the surface and making groove into cracks 5mm x 10mm and cleaning the surface and pouring the material into cracks etc. complete.
