202.04 Construction Requirements
A.General. At the end of each day provide a smooth transition between areas where pavement has been removed and areas from which traffic can enter the removal area. Replace items designated for salvage that are lost or damaged by work activities with new items, meeting the appropriate specifications, at no additional cost to the Department. Begin and end removal of existing bituminous and concrete surfaces at a joint or create a smooth, vertical plane along the entire length of the remaining surface. Backfill and c ompact material used to fill cavities within the boundaries of the roadbed as specified in Section 203.04 G .2, “Compaction Control, Type A”. Backfill and compact material used to fill cavities outside the boundaries of the roadbed as specified in Section
203.04 G.4, “Compaction Control, Type C” to the same level as the surrounding undisturbed
ground. Before backfilling over concrete slabs that will remain in place, break up the slabs to facilitate drainage.
B.Removal of Structures and Box Culverts. If bridge elements are designated for salvage, matchmark the elements and transport them to the location specified in the contract. Remove portions of structures within the limits of a new structure to accommodate the construction of the new structure. In other areas, remove existing substructures to one foot below the existi ng stream bottom and remove those parts outside the stream to one foot below final ground surface. When removing a bridge, perform asbestos inspection and testing and submit SFN 17987 “Asbestos Notification of Demolition and Renovation” to NDD EQ at least 10 working days before demolition. If asbestos is discovered, the Engineer will issue a contract revision for work related to the asbestos. In-Depth Review 2022 Section 202 140 C. Removal of Pipe Conduit. Dispose of unsuitable or excess excavation at an approved location.
D.Removal of Paving Materials ( Bituminous, Concrete, and Aggregate Materials). If paving materials are designated salvage material, ensure the material is not contaminated with dirt or other deleterious material. Deleterious material includes all steel mater ial within concrete pavement
E.Removal of Manholes and Inlets. Remove manholes or inlets by removing the casting, rings, barrel, and base; plug or cap the existing lines; and backfill to grade.
202.05 Method of Measurement
A.General. The Engineer will measure as specified in Section 109.01, “Measurement of Quantities” and as described in this section.
B.Removal of Pipes, Culverts and End Sections. If only the end section is designated to be removed from a pipe location, the Engineer will measure the end section by the each removed. If pipe, or portions of a pipe, and end sections are to be removed from a location, the Engineer will measure removal of pipe conduit along the top of the pipe. The Engineer will not measure flared end sections. Flared end sections will be considered part of the pipe.
C.Removal of Concrete. The Engineer will include the reinforcing steel in the total weight when the Department pays for removal of concrete pavement by the ton.

In-Depth Review 2022 Section 203 142 SECTION 203 EXCAVATION AND EMBANKMENT
203.01 Description
A.General. This work consists of the excavation, haul, placement, disposal, and compaction of embankment material.
B.Common Excavation. Common excavation consists of excavation withi n the right of way, not otherwise classified.
C.Rock Excavation. Notify the Engineer if detached rock s having a volume of 0.5 cubic yard or larger are discovered or if rock excavation methods are required for the excavation of material or boulders. Rock excavation methods include: − Blasting, before material can be excavated and removed; or − Material that requires heavy -duty dozer -mounted rippers or dozer blades to break the material into chunks of more than one cubic foot, before material can be excavated and removed.
D.Shale Excavation. Notify the Engineer if shale excavation is required before performing the excavation. Shale excavation includes: − Excavating material that is laminated, fissile, or sedimentary material that is principally composed of fine-grained particles; or − Material that requires heavy -duty dozer -mounted rippers or dozer blades to break the material into chunks of one cubic foot or less, before material can be excavated and removed.
E.Muck Excavation. Notify the Engineer if muck excavation is required before performing the excavation. The Engineer will classify the excavation as muck when both criteria below are met: − The material is a saturated mixture of soils and organic matter unsuitable for use as embankment; and − The material cannot be excavated using the methods the Contractor is using to perform the majority of the surrounding excavation.
F.Borrow Excavation. Borrow Excavation consists of the use of material obtained from outside the right of way for construction. Borrow may be obtained by either the Contractor or the Department, depending on the specific contract requirements.
