The working Bench Marks shall be at the rate of four per km and also at or near all drainage structures, over-bridges and underpasses. The average thickness of the pavement course in any area shall be the arithmetic mean of the difference of levels before and after construction at all the grid points falling in that area, provided that the thickness of finished work shall be limited to those shown on the drawings or approved by the Engineer in writing. The quality of materials, processing of materials as may be needed at the site, salient features of the construction work and quality of finished work shall comply with the requirements set forth in succeeding sections.

The quality of materials, processing of materials as may be needed at the site, salient features of the construction work and quality of finished work shall comply with the requirements set forth in succeeding sections. Notwithstanding the above, the measurements may be taken at closer intervals also, if so desired by the Engineer, the need for which may arise particularly in the case of estimation of the volume of the material for profile corrective course levelling course. The Engineer will provide the Contractor with the data necessary for setting out of the center line. The Contractor shall furnish, at least 15 days in advance, his programme of commencement of item of work, the method of working he intends to adopt for various items of work such as site clearance, construction for embankment, sub-base, base, surfacing, culverts, bridges, retaining walls, well-sinking, cast-in-situ piling, construction of cast-in situ prestressed concrete simply supported girders, cantilever construction of prestressed concrete superstructure, and such other items for which the Engineer demands the submission of the method of working.

Before taking up any construction, an agreed phased programme for the diversion of traffic on the highway shall be drawn up in consultation with the Engineer. Programme relating to pavement and shoulder construction shall be an integrated activity to be done simultaneously in a coordinated manner. Use of Nuclear Gauges Nuclear gauges shall be used only where permitted by the Engineer. It is one of the common causes of failure where without proper investigation of existing pavement composition with impervious bituminous layers underneathfresh non bituminous layer has been laid over existing road surface. The work of setting out shall be deemed to be a part of general works preparatory to the execution of work and no separate payment shall be made for the same.
Control of Soil Erosion, Sedimentation and Water Pollution The Contractor shall carry out the works in such a manner that soil erosion is fully controlled, and sedimentation and pollution of natural water courses, ponds, tanks and reservoirs is avoided. The Contractor will be the sole responsible party for safe-guarding all survey monuments, bench marks, beacons, etc. In order to facilitate the setting out of the works, the centre line of the carriageway or highway must be accurately established by the Contractor and approved by the Engineer. Measurements of Lead for Materials Where lead is specified in the Contract for construction materials, the same shall be measured as described hereunder: Lead shall be measured over the shortest practicable route and not the one actually taken and the decision of the Engineer in this regard shall be taken as final. The work to be carried out under the Contract shall consist of the various items as generally described in the Tender Documents as well as in the Bill of Quantities furnished in the Tender Documents. If at all, it would be detrimental. The work of building in quality assurance shall be deemed to be covered in the scope of the work.
General The Contractor shall take all precautions for safeguarding the environment during the course of the construction of the works. Different items of work shall be measured in accordance with the procedures set forth in the relevant sections read in conjunction with the General Conditions of Contract. Where it is necessary to use some substances which can cause injury to the health of workers, the Contractor shall provide protective clothing or appliances to his workers. Measurement of distances shall be done preferably using precision instruments like Distomat. The Contractor shall, in connection with the staking out of the centre line, survey the terrain along the road and shall submit to the Engineer for his approval, a profile along the road centre line and cross-sections at intervals as required by the Engineer.
The construction of temporary diversion including temporary cross drainage structures as described in Clause 112. He shall provide information regarding the details of the method of working and equipment he proposes to employ and satisfy the Engineer about the adequacy and safety of the same. A list of Indian roads Congress Specifications and Recommended Codes of Practice which have been made use of in the preparations of these Specifications is given at Appendix-1. Measurement of Bituminous Courses for Payment on Weight Basis Plant-mixed bituminous materials for pavement courses where designated to be paid on weight basis shall be weighed on accurate scales approved by the Engineer. Two copies of drawings, on the basis of which actual execution of the work is to proceed, shall be furnished free of cost to the Contractor by the Engineer progressively according to the work programme submitted by the Contractor and accepted by the Engineer.

However, where work is allowed by the Engineer in longer stretches passing places atleast 20m long with additional paved width of 2. Morth Specifications for Road and Bridge Works, 5th Revision However, in recent morth specifications 5th revision some initiative from Government's end has been taken to develop the roads of the state. The Contractor shall establish working Bench Marks tied with the Reference Bench Mark in the area soon after taking possession of the site.
