PROJECT ESTIMATES FOR HIGH WAYS FIELD RECONNAISSANCE AND SURVEY WORK OF THE ALIGNMENT OF HILL ROADS.

People raising various complaints during the course of change in the alignment of the Highway and route along which the road is located by the initial lay out or when carrying out the detailed survey work of the road boundaries fixed by the department concerned or the agency doing the work of locating the center line of the road. As for as hill roads are concerned, it should be on the side of the rock which is sound and solid. The dip of the strata in the side of hill should not be towards the road otherwise land slides will occur and there should also be no inclined fissures. As for as the progress of the laying out the alignment of the road is concerned it depends upon the nature of the profiles and the geographic conditions of the area covered for the survey work taken in hand by the participants, doing the survey work where in on an average a party can cover about six Km per day in the plains (adding extra time for laying the curves) however in the case of hills there is very less progress as compared to the plains, for which surveying instruments are required again and again altered from the place of fixation for the marking. Where the side slopes of the area covered are steeper than 1 in 15 , there cross section should be taken more closer than thirty metres of the intervals, and sufficiently for on each side of the centre line to allow for the adjustment of the alignment. A wide belt on the either side should be examined. The general examination enables the Engineer to select one or more promising routes which have to be investigated in detail. A road project should contain the following information and the report should be brief but full of all the important information and must outline, previous history of the road if any existing, or history of the proposal of the road its present conditions, topographical and geographical features, possible future development of the areas surrounding the road, rainfall and floods etc. It is too necessary to give details of the proposed alignment its special features and justification for the selection of the particular alignment. Formation width with relation to the existing and future traffic, land width to be acquired, permanent and temporary acquisition. Masonry works to be built, Bridges, culverts, causeways, drainage, Retaining walls etc etc. There is no need of providing passing places on two lane National and State Highways having roads with as recommended, but in the case of single lane sections of National/State Highways which gave a narrower road way, provision of some passing places will be desired.
