Construction of Embankment with Material obtained from Borrow pits Construction of embankment with approved material obtained from borrow pits (land own/arrange by Govt.)with all lifts and leads, transporting to site, spreading, grading to required slope and compacting to meet requirement of table 300-2 & 300-1 .The size course material in the mix of earth ordinarily shall not be exceed 75mm.(Reference to MoRT&H's specification clause 305).

Construction of Embankment with Material obtained from Borrow pits Construction of embankment with approved material obtained from borrow pits with all lifts and leads, transporting to site, spreading, grading to required slope and compacting to meet requirement of table 300-2 & 300-1 .The size course material in the mix of earth ordinarily shall not be exceed 75mm.(Reference to MoRT&H's specification clause 305). NB: Cost of compensation for Earth material & its carriage from private land at 5km distance have been included in the rate. Note: Royalty will be deducted from the agency's bill as per Govt. Rule.

Construction of Embankment with Material Deposited from Roadway Cutting Construction of embankment with approved materials deposited at site from roadway cutting and excavation from drain and foundation of other structures graded and compacted to meet requirement of table 300-2 & 300-1.The size course material in the mix of earth ordinarily shall not be exceed 75mm.(Reference to MoRT&H's specification clause 305). Note:In case the earth cutting is done by dozer and pushed for filling in the embankment, the input of dozer in the cost of embankment i.e. ₹ 39.63/m3 (excluding overhead, Contractor profit & L.W. cess)shall be deducted from the Rate and the same is already provided in the cost of excavation. However, if the earth is dumped by tippers from roadway cutting, the input of dozer for spreading is required to be provided.

Excavation in Soil using Hydraulic Excavator CK 90 and Tippers with Disposal upto 1000 metres. Excavation for roadwork in soil with hydraulic excavator of 0.9 cum bucket capacity including cutting and loading in tippers, trimming bottom and side slopes, in accordance with requirements of lines, grades and cross sections, and transporting to the embankment location within all lifts and lead upto 1000m (Reference to MoRT&H's specification clause 301).
