(b) Plan showing the Plan View And Longitudinal Profile The plan view and the longitudinal profile should be shown in the same plan and shall be as follows:(i) Top Section of Plan-Plan View These shall show the route centre-line, tangent points, intersection points (with rectangular coordinates at road junctions), intersection angles, bearings of all the straights, chainages of tangent points and centre-line markers, levels of Temporary Bench Marks, contours of corridor surveyed, streams, rivers, positions of proposed culverts (if determined already) and other features, crop and vegetation detail to a scale of 1: 1000. All base stations such as boundary stones, survey department Bench Marks, trigonometrical stations shall also be clearly stated and indicated on the drawings. (ii) Bottom Section of Plan-Longitudinal Profile These shall show the longitudinal profile of the route centre-line, cross-section of the rivers, positions of culverts, highest known flood level (if any), swamps and their water level and other features needed for design considerations. Scale: Horizontal (1 : 1000) Vertical (1 : 100) (c) Plans for Bridge and Culvert Sites These shall show features and levels as detailed in Clause 3.3.4 above and are to be of suitable scale for Al size drawings. (d) Cross-Sections Drawings of all the cross-sections along the centre line of the proposed road, shall be plotted in consecutive order, to a scale of 1:100 both horizontal and vertical. The drawings shall show details of ground levels and distances from the centreline of the proposed road. (e) Plans for Preliminary Design A set of prints listed under Clause 4.1(b) Cawangan Jalan, Ibu Pejabat JKR, K.L

TOR for Detailed Ground Survey shall be submitted together with the survey data listed under Clause 4.2.These prints can be made from the same negatives used for drawings listed under Clause 4.1(b) and may exclude contours of corridor surveyed and other features such as crops and vegetation details. All horizontal intersection points should be clearly numbered on these prints. A layout plan with horizontal. intersection points, bearings and distances between IPs shall be included. (f) Land Acquisition Plans The Surveyor shall compile and prepare base plans for property and land acquisition purposes from the Survey Department cadastral sheets and latest revenue sheets from the Land Office and other Government land scheme agencies where relevant to the same scale. This drawing shall show: (i) lot boundaries within the surveyed corridor (ii) lot numbers (iii) lot areas computed based on coordiates. (Determination of areas by measurement is not acceptable). (iv) land use indicating type of cultivation. (v) types of buildings indicating permanent or semi-permanent - usage of the building whether commercial, industrial, religious, communal, schools etc. (vi) size of all buildings shall be plotted to scale and correct shape. (vii) show clearly whether the affected buildings are within the construction limits or within the R.O.W. (viii) pay special attention to burial grounds if any fall within the survey corridor. (ix) other relevant details such as dimensions of the lots, coordinates of the boundary of the lots etc. The drawing of this base plan does not include the preparation of the final land acquisition plan nor the computation of the area to be acquired.

4.2

Survey data for Preliminary Design The Surveyor shall provide the Government with one set of survey data prior to the submission of the complete survey plan. These data shall be presented as follows: (i) Natural Ground Surface Natural ground surface data neatly presented to the format required. (ii) Horizontal Intersection Points (I.P.) The following data shall be recorded and neatly tabulated. (a) Name or number of the road (b) I.P numbers (c) Distance to the next I.P (d) Azimuth in deg-min-sec. The I.P number shall coincide with those on the plans listed under Clause 4.1 (b). 4.3

Format of the Plans and Drawings All formats of plans submitted including the title block shall conform to JKR Guidelines as contained in Arahan Teknik (Jalan) 6/85 (Guidelines For Presentation of Engineering Drawings). All drawings shall be to Al size unless otherwise specified. All legends and symbols used in the plans shall be those. currently used by the JKR and approval must be obtained for any departure from accepted practice. 4.4
