<br /> <br />e <br /> <br />e <br /> <br />e <br /> <br />" <br /> <br />JfIIARKHURD <br /> <br />Topographic Mapping <br /> <br />We will digitally collect planimetric and Digital Terrain Modeling (DTM) data for a <br />designed scale of 1" = 100', showing 2-foot contour intervals. <br /> <br />The attached level/layer list itemizes the features which, to the extent they are visible on <br />the photography, will be collected. Please review this list and notify us if the features we <br />intend to show do not meet your needs. <br /> <br />Digital map delivery will consist of AutoCAD version 12, 2D planimetric and contour <br />files, and a Softdesk 3D-DTM file, on 3.5" floppy diskettes. Unless furnished with <br />specific requirements, we will use our judgment in title and border information. <br /> <br />As an option, we can provide you with high quality mylar laser plots, in 1/4 section area <br />format. We estimate 9-10 sheet, ..:i:. 32" x 32" overall, will cover the entire area. <br /> <br />Map Accuracy and Liability <br /> <br />By accepting this proposal, you agree the work described herein will meet your intended <br />purpose. The use of this map for a purpose other than that which is originally designed <br />may render the map unreliable. <br /> <br />Except where the ground may be obscured, map accuracy will comply with National Map <br />Accuracy Standards. Briefly, these state that 90% of all well defined features shall be <br />correct within 1/30 inch, and 90% of all elevations correct within 1/2-contour interval. If <br />areas are obscured, contours will be dashed to indicate they are approximate. The <br />accuracy standards should be applied only to the basic scale and contour interval 1" _ <br />100', 2' C.!. for which the maps were designed. <br /> <br />MARKHURD's liability, in the production or use of these maps, for any inaccuracies that <br />may be found in these maps, shall be limited to the correction of such inaccuracies, and <br />shall not exceed the contract value of the maps. No representations or warranties are made <br />other than those stated herein. <br /> <br />Performance Schedule <br /> <br />We will furnish MSA a set of aerial photographs indicating the control requirements within <br />3 days after receipt of notice to proceed. The time required to deliver the completed <br />mapping will depend, to some extent, upon our work load when completed ground control <br />is furnished. However, we estimate that delivery can be made within 12 working days <br />after its receipt. <br />
