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. Nuclear gauges shall be used only where permitted by the Engineer. The Contractor shall provide the Engineer with a copy of the regulations governing the safe use of nuclear gauges he intends to employ and shall abide by such regulations. The Contractor must take all reasonable steps to minimise dust nuisance during the construction of the works.

Clearance shall be effected immediately by manual sweeping and removal of debris, or, if so directed by the Engineer, by mechanical sweeping and clearing equipment, and all dust, mud and other debris shall be removed entirely from the road surface.


Additionally, if so directed by the Engineer, the road surface shall be hosed or watered using suitable equipment. The Contractor shall at all times carry out work on the highway in a manner creating least interference to the flow of traffic while consistent with the satisfactory execution of the same.

For all works involving improvements to the existing highway, the Contractor shall, in accordance with the directives of the Engineer, provide and maintain, during execution of the work, a passage for traffic either along a part of the existing carriageway under improvement, or along a temporary diversion constructed close to the highway. The Contractor shall take prior approval of the Engineer regarding traffic arrangements during construction.

The treatment to the shoulder shall consist of providing atleast mm thick granular base course covered with bituminous surface dressing in a width of atleast 1. The continuous length in which such work shall be carried out, would be limited normally to m at a place. However, where work is allowed by the Engineer in longer stretches passing places atleast 20m long with additional paved width of 2.

However, in case where on the request of the Contractor, work on existing two-lane carriageway is allowed by the Engineer with traffic using part of the existing carriageway, stipulations as in para above shall apply. After obtaining permission of the Engineer, the treated shoulder shall be dismantled, the debris disposed of and the area cleared as per the direction of the Engineer.

MORTH Specification Book 4th revision | Transport | Nature

In stretches where it is not possible to pass the traffic on part width of the carriageway, a temporary diversion shall be constructed with 7 m carriageway and 2. The alignment and longitudinal section of diversion including junctions and temporary cross drainage provision shall be as approved by the Engineer.

The Contractor shall take all necessary measures for the safety of traffic during construction and provide, erect and maintain such barricades, including signs, markings, flags, lights and flagmen as may be required by the Engineer for the information and protection of traffic approaching or passing through the section of the highway under improvement. 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.

Red lanterns or warning lights of similar type shall be mounted on the barricades at night and kept lit throughout from sunset to sunrise. At the points where traffic is to deviate from its normal path whether on temporary diversion or part width of the carriageway the channel for traffic shall be clearly marked with the aid of pavement markings, painted drums or a similar device to the directions of the Engineer. At night, the passage shall be delineated with lanterns or other suitable light source.

One-way traffic operation shall be established whenever the traffic is to be passed over part of the carriageway inadequate for two-lane traffic. This shall be done with the help of temporary traffic signals or flagmen kept positioned on opposite sides during all hours.

On each approach, at least two signs shall be put up, one close to the point where transition of carriageway begins and the other m away. The signs shall be of approved design and of refectory type, if so directed by the Engineer. Maintenance of Diversions and Traffic Control Devices.

The temporary travelled way shall be kept free of dust by frequent applications of water, if necessary. All arrangements for traffic during construction including provision of temporary cross drainage structures, if required, and treated shoulder as described in Clause The construction of temporary diversion including temporary cross drainage structures as described in Clause All measurements shall be made in the metric system.

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. The same shall not, however, apply in the case of lump sum contracts. All measurements and computations, unless otherwise indicated, shall be carried nearest to the following limits:.

In recording dimensions of work, the sequence of length, width and height or depth or thickness shall be followed. 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. Distances upto and including m shall be measured in units of 50 m, exceeding m but not exceeding 1 km in units of m and exceeding 1 km in units of m,the half and greater than half of the unit shall be reckoned as one and less than half of the unit ignored.

In this regard, the source of the material shall be divided into suitable blocks and for each block, the distance from the centre of the block to the centre of placing pertaining to that block shall be taken as the lead distance. The finished thickness of sub-base, base and bituminous courses to be paid on volume basis shall be computed in the following manner:.

Levels shall be taken before and after construction, at grid of points 10 m centre to centre longitudinally in straight reaches but 5 m at curves. Normally, on two-lane roads, the levels shall be taken at four positions transversely, at 0. For multi-lane roads, levels shall be taken at two positions transversely for each lane at locations specified by the Engineer.

For pavement courses laid only over widening portions, atleast one line of levels shall be taken on each strip of widening, or more depending on the width of widening as decided by the Engineer.

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 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.

Where payment for any bituminous course in Section is allowed to be made on area basis, the Engineer may have its thickness checked with the help of a suitable penetration gauge at regular intervals or other means as he may decide. 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. Approved scales shall mean scales that are of size, capacity, kind and type suitable for the weighing to be done, and these shall be properly and adequately installed and maintained.

Prior to the use of the scales and as frequently thereafter as the Engineer may deem necessary to ensure accuracy, the scales shall be checked and approved by the Engineer, or the Engineer may direct the Contractor to have the scales checked by other competent agency at the cost of the Contractor. Location of the scales shall be as designated by the Engineer. Trucks used for hauling the material to be weighed shall be weighed empty daily at such times as the Engineer directs, and each truck shall bear a plainly legible identification mark.

For materials specified to be measured by weight, the Engineer will have the option to make measurements of the finished work by volume in accordance with Clause The factor for conversion from volume measurement to weight measurement shall be computed from the representative density of the compacted material at site determined at locations approved by the Engineer.

For item rate contracts, the contract unit rates for different items of work shall be payment in full for completing the work to the requirements of the Specifications including full compensation for all the operations detailed in the relevant sections of these Specifications under ARates. In the absence of any directions to the contrary, the rates are to be considered as the full inclusive rate for finished work covering all labour, materials, wastage, temporary work, plant, equipment, over-head charges and profit as well as the general liabilities, obligations, insurance and risks arising out of General Conditions of Contract.

Accordingly, other agencies employed by the Employer may be working in the vicinity of the Works being executed by the Contractor. The Contractor shall liaise with such agencies and adjust his construction programme for the completion of work accordingly and no claim or compensation due to any reason whatsoever will be entertained on the account.

The Employer will be indemnified by the Contractor for any claims from other agencies on this account. Prior to start of the construction activities at site, the Contractor shall, within 30 days after the date of the Letter of Acceptance, submit to the Engineer for approval, the detailed construction methodology including mechanical equipment proposed to be used, sequence of various activities and schedule from start to end of the project. Programme relating to pavement and shoulder construction shall be an integrated activity to be done simultaneously in a coordinated manner.

Section 100 (MORTH, 4th Revision)

The methodology and the sequence shall be so planned as to provide proper safety, drainage and free flow of traffic. Approval of all sources of material for work shall be obtained in writing from the Engineer before their use on the project. Raw and processed samples of the mineral aggregates from the approved quarry shall be submitted by the Contractor at no extra cost. Even in that case the load and intensity of construction traffic should be so regulated that no damage is caused to the subgrade or pavement layers already constructed.

Where necessary, service roads shall be constructed for this purpose and the same shall be considered as incidental to the work. The wheels or tracks of plant moving over the various pavement courses shall be kept free of deleterious materials. Bituminous base course shall be kept clean and uncontaminated as long as the same remains uncovered by a wearing course or surface treatment.

MORTH Specification Book 4th Revision

Should the base course or track coat on the base course become contaminated, the Contractor shall make good by clearing it to the satisfaction of the Engineer, and if this is impracticable, by removing the layer and replacing it to Specification without any extra cost. The work covers the construction and provision of furnished site office accommodation for the supervisory staff of Engineer and maintaining the same. The Contractor shall arrange to provide fully furnished office accommodation constructed as shown in drawings.

Work includes providing electric supply, all electrical items like lights, fans and complete wiring, providing water supply including all pipes, fittings, tanks, tube well, pumps, valves etc. The Contractor shall provide the office accommodation within 4 months from the date of the commencement of work or 3 months from the date of providing the land and the working drawings for the construction of office accommodation, whichever is later.
