Referring to your HN 1533 it 1s important that this office have sufficient infor
mation available on the
survey methods used and accuracy obtained in the
positioning of stations 10, 30, 40 and 90 to assure efficient future design
and to answer any questions of tha client in this regard.
mation should be sulmitted for this purpose.
The following infor
(1) Summary of methods and procedure for each of the four stations.
(2) Analysis of the results of positioning by intersection of theodolite
angles.
This should include the coordinate relation of each theodolite
position check from which the mean or final valves of a station wera obtained,
(3) Copies of field notes and computations related to the positioning of
each station,
(4)
Copies of field notes and computations of any expansion of primary
horizontal accomplished to provide local control for positioning of these stations,
(5) Copies of the results obtained by any observations to determine the
yaw, roll, pitch and horizontal motion of a station around a fixed point.
Item (1) 1s required as soon as possible for inclusion in the narrative portion
of the survey seation of the completion report. The remaining items should be
sutmitted as early as the information can be compiled as some of this information
may be inoluded in the report.
