Request for Proposal (“RFP”) issued by NHIT Eastern Projects Private Limited (NEPPL) for Engagement of Agency/Firm for Repair & Rehabilitation work of Rigid Pavement of four-lane of Lakhnadon – Khawasa Toll Road Project in the State of Madhya Pradesh.

Dismantling of Cement Concrete Pavement Scope of Work: Dismantling of cement concrete pavement by mechanical means using pneumatic tools, breaking it into pieces not exceeding 0.02 cu.m, stockpiling at designated locations, and disposing of both serviceable and unserviceable material separately within 1000 metres lead. Execution Requirements: 1) Mark dismantling area and barricade the site. 2) Break the pavement using pneumatic/mechanical tools into ≤0.02 cu.m pieces. 3) Stockpile reusable and non-reusable material separately. 4) Transport and stack materials within 1000 m lead. 5) Ensure site cleaning and safety throughout. Rate Inclusions:Includes labour, dismantling tools or machinery, cutting (if needed), excavation/backfilling (as applicable), transportation of materials within 1000 m, and stacking of reusable/unusable material separately. Includes all safety, environmental, and supervision-related requirements. Relevant Code / Specifications:MoRTH Clause 202 (Generalized)

Add extra in Item for the cost of steel in dowel bar and tie rod including craddle, laps etc. complete required as per design.

Cement Concrete Pavement Scope of Work: Construction of unreinforced, dowel-jointed, plain cement concrete pavement over a prepared sub-base. The concrete shall be mixed in a mixer machine (fiury) , transported, laid manually, compacted, and finished as per line, level, and grade. The work includes joint construction, curing, and surface finishing for rigid pavement. Execution Requirements: 1) Use 43 Grade OPC cement @ 410 kg/m³ with coarse and fine aggregates conforming to IS:383. 2) Maximum coarse aggregate size shall be ≤ 25 mm; concrete mix shall achieve flexural strength ≥ 4.5 MPa at 28 days. 3) Concrete shall be mixed in a mixer machine (fiury) and transported to site. 4) Laid manually, compacted, and finished as per design. 5) Joints to be provided with dowel bars, tie rods, filler board, sealant, debonding strip as specified. 6) Apply curing compound and cure the surface for a minimum of 14 days. Rate Inclusions: The rate includes cost of all materials such as cement, fine and coarse aggregates, admixtures, curing compound, joint filler, sealant, ; batching, mixing, transport, laying by manual, compaction, surface finishing, joint construction, curing, labour, equipment, safety measures, and quality control. Relevant Specification: MoRTH Clause 602

DRY LEAN CEMENT CONCRETE SUB-BASE : Construction of dry lean cement concrete Sub- base over a prepared sub-grade or drainage layer with coarse and fine aggregate conforming to IS: 383, the size of coarse aggregate not exceeding 25 mm, aggregate cement ratio not to exceed 15:1, aggregate gradation after blending to be as per table 600-1, cement content not to be less than 150 kg/ cum, optimum moisture content to be determined during trial length construction, concrete strength not to be less than 10 Mpa at 7 days, mixed in a batching plant, transported to site, laid with a paver finisher with electronic sensor, compacting with 8- 10 tonnes vibratory roller, finishing and curing as per clause 601 of specification complete in all respect.

STAPLING: Crack stitching with V-bars (Stapling) to be used for cracks in reasonably good condition in order to arrest movement of slabs and slab pieces by making the position of vertical holes of dia 30 mm at a distance of 228 mm form the crack at spacing of 600 mm center to center, drilling holes, Slit removing, Devris cleaning from the holes, roughen the sites of hole and slit by sand blasting, sand paper. Insert the steel bar (FE 500), fill the holes and silt with epoxy mortar (1:3 epoxy: sand) up to 10mm above the top surface of steel bar. Filling with non-shrinkable concrete or any other equivalent material may be filled up to the top level of PQ2 and fill the sides of the groove with low visco sity epoxy following the IRC SP 83:2008.
