VI. Detailed Work at Site Investigated 



(1) Scope of the Inspection at the Site. If a definite and well- 

 defined project be investigated, the engineer making the inspec- 

 tion should study the general scheme carefully in the light of his 

 personal inspection of the ground, and should record his opinion 

 as to the engineering and economic feasibility of the same, pointing 

 out whatever weaknesses may be apparent, and recommending 

 whatever changes in design, layout or scheme of development he 

 may consider advisable. 



When no definite scheme of development has been proposed, 

 the inspecting engineer is expected to outline the most feasible 

 scheme which his study on the ground may suggest, setting out the 

 head available and method of securing the same. He should also 

 gather all information and field data which may be essential to its 

 proper consideration and to getting out the estimates. A layout 

 of his scheme, together with all pertinent data, should be plotted 

 on the contour plan of the site. 



Arrangements should be made on the ground for the installa- 

 tion and continued reading of gauges at all points where the record 

 of the same is advisable. 



Numerous photographs illustrating the site are required. 



(2) Accessibility of Site. Secure all data with reference to 

 accessibility of the site. This includes the distance to the nearest 

 railway line; the ease or difficulty of building a spur line to the site 

 should the size of the development warrant it; the condition of 

 any roads in the vicinity and their suitability for heavy transport; 

 the length of new road that may be required; the use which can 

 be made of water transportation as a means of access. In brief, 

 the best means of connecting the site with existing lines of traffic, 

 should be covered. 



(3) Detailed Information and Plans at Site. (a) Contour Plan. 

 Enough rough instrument work must be done to permit of plot- 

 ting a fairly accurate contour plan of the whole vicinity covered by 

 the proposed layout. These contours should extend above the
