SECTION 3 -SCHEDULE
3.1 -Key Dates
The schedule for preparation and production of Volumes 1 and 2 together with
the appendices is presented on the following schedul~ sheets.
Key dates for the Report and related deliverables are as follows:
First Draft of Report and Appendices to Client for Review ........ February l, 1982
Final Seismic Report Issued by Woodward-Clyde ...•................ February 1, 1982
Environmental Component of Feasibility Report (Volume 2)
issued byTES for review by Client •.............................. ·March 1, 1982
Comments and Revisions to First Draft of Report ·
and Appendices Completed.: ...•................................•..• Mal .. ch 1, 1982
Final Draft of Report and Appendices Delivered to Client .......... March 15, 1982
First Draft of Project Overview Report ...... "····················· March 15, 1982
Final Draft of Project Overview Report ............................ April/82
Final Feasibility Report Issued to Client ......................... Apri-l 30, 1982*
*Subject to receipt of comments and responses
First draft issue of the Report will be limited to less than 25 copies. Final
draft and final issues will be as indicated in Section 5.
3.2 -First Draft Issue
The first draft issue of the report (February 1, 1982) will be limited to less
than 25 copies. The purpose of this issue is to give the Client an opportunity
to comment on the report. In this regard, the text should be reasonably complete
and readable, however, final and comprehensive proofreading will not likely be
possible at this time. Simiarly, drawings (plates or figures) accompanying this
first draft, should be complete enough to illustrate their specific purpose,
but not necessarily with drafting check or all the finishing touches for final
reproduction completed. Some drawings may possibly have to follow the
February 1 issue date.

It is not anticipated that the Client's col'tlTlents will result in serious changes
to drawings. We should, however, be prepared to modify the text significantly
as a result of this first draft review.
3.3 -Final Draft Issue
This is the key issue (March 15.., 1982) for the Report. It is expected that 2
weeks will be required to assemble, reduce, print, collate, bind and ship the
Report, so that all text, figures and plates must be complete by March 1, 1982.
3.4 -Other Material
The schedule and details of the final iss1J~ of the Feasibility Report and of the
Project Overview Report will be provided later. ·

SECTION 6-
6.1 -General
Graphical presentations will be either in the form of figures or plate~. Preparation
of figures and plates shall be in accordance with Attachment B -Susitan Hydroelectric
Project -Feasibility and Geotechnical Reports -Drafting Procedures, and Acres
Drafting Standards for Hydroelectric & Heavy Civil Projects, dated February 20, 1980
or subsequent revisions.
6.2 -Figures
For the purpose of the Report, figures fall into one or more of the following
categories:
- a chart, graph, simple drawing or map which is meant· to be read in conjunction
with a specific section of the text;
-a chart, etc. published by others which is required to illustrate or complement
the report.
• The figure will be inserted at the back of each section. Wherever a choice is
possible, figures should be 8-1/2 " x 11 11 (final size) although 11" x 17" ~ll be
aq:epted grudgingly. (The 11 11 x 17 11 size causes complications during binditng
since it must be folded and iLserted in the text.) A typical figure arrangement
is presented in Attachment B.
In order to improve clarity, where appropriate, figures which contain a great
deal of 1tne work should be-drawn oversize for reduction. This will not be
practical in all cases, of course, and caution and judgement should be used with
material from other sources, since reduction often reduces clarity in these
cases.

6.3 -Plates
Plates will fall into one or more of the following categories:
-a drawing prepared for other project purposes (i.e., preliminary design, etc.);
-a drawing referred to in more than one section of the Report; or
- a drawing ~>.~hich will be used for the FERC 1 i cense application.
Plates will be limited to 11 inches by 17 inches in their final reduced version in
the Report. Color may be used where appropriate, although color presentations
should be coordinated with the Technical Editor to ensure reasonable uniformity of
presentation and to avoid excessive cost.
Drawings shall be prepared suitable for reduction. In general, it is preferable
to prepare drawings to a larger scale and to reduce them, since clarity is improved
by this means. Accordingly, preparation of drawings to final 11 11 x 17 11 size
should be avoided, particularly where line work is congested or complicated.

DRAFTING STANDARDS
1 -INTRODUCTION
This Drafting Instruction is issued to supplement Acres Standards and to
further clarify certain details which are pertinent to this project. If any
conflict exists between the two, this Instruction shall be used.
Acres Standards and this Instruc.tion are issued to maintain uniformity in
drawing presentation and as a guide to good drafting. practice. ALL DRAFTING
PERSONNEL MUST BECOME THOROUGHLY FAMILIAR WITH BOTH OF THESE STANDARDS. It
is understood that not all specific examples can be illustrated in the Stan-
dards. Drafting Personnel are expected to use initiative and creative
abilities in the preparation of drawings within the constraints of the
Standat:ds.

2 -BUDGETS , SCHEDULES , AND RECORDS
2.1 -Responsibiliti
The squad leader and departmental coordinator shall be jointly -responsible
for budgets and schedules covering the. preparation of drawings by their
respective depart~ents.
2.2 -Schedules
The squad le~der shall prepare schedules for each drawing taking into con-
sideration the time allotted (Budget), date the drawing is to be started,
availability of inf:").rmation, and completion date (Schedule).
2.3 -Work Assignment (Form AAl-001)
This is to be completed by the squad leader for each drawing or series of
drawings, if more than one sheet is required.
2.4 -Dr~tJing Record (Form AAI-002)
The squad leader shall complete the top portion to convey to the draftsman
~
the hours budgeted for each section of work to be compl-eted. The draftsman
shall keep the Drawing Record up-to-date by m:aking daily entries of the time
charged.
2.5 -Drawing Mock-ups
When a complex drawing is to be prepared, a mock-up or blackout shall be
' prepared by the squad leader (Form AAl-003). Its purpose is to pre-p1an the
arrangement of views in order to produce a well-balanced drawing. The
information may be drawn or sketched freehand but must be in the same
proportion as the form is to the drawing.

3 -BASIC DRAFTING PRINCIPLES
3 .1 -General
The squad leadar w.ill coordinate the preparation of all drawings done under
his direction; co:mm.ents and information for drafting shall ~be directed
through the squad leader. The squad leader will be responsible for the
quali.ty of the work consistent with the requirements of the Standards. The
project engineer, department head, departmental chief of drafting, and
department coordinator will resolve differing interpretations of the Stan-
dards whenever required.
Sketches and final drawings shall be ·complete and clear to avoid any possi-
bility of more than one interpretation. Except for special details, work
shall be done in Third ~~gle Projection. Unnecessary repetition of informa-
tion and use of extraneous dimensions which are not required for construc-
tiOJ.?. or location must be avoided.
PLAN. views shall be drawn in the upper left-hand corner of the she.et with
not less than one inch clear space from the top or side border lines.
PLAN views shall commence from lowest elevation, with other elevations,
sections, and details following in that order.
Where several DETAILS are shown on one drawing, those relating to each other
shall be grouped together; when details require only part of a sheet~ do not
.center them on the sheet or use space unnecessarily (additional space is
often required later for other details).
PLANS shall refer to. the elevation at which they are drawn.; SECTIONS and
ELEVATIONS shall be identified with letters in order of sequence dra~~~ (with
t;he letters I and 0 omitted; when sections beyond the letter Z are required .
use double letters beginning with AA, BB, CC, etc.); and DETAILS identified
by numbers in order of sequence drawn.

4 -PREPARATION OF DRAWINGS
4.1 -Drawing Sheets
All drawings shall be produced on standard
pre-printed on .003 translar, matte two sides.
2Tf x 38-1/2 •• (see Exhibits 4 and 5).
4.2 -Reduction
• •
' 4-1
size sheets. Sheets are
Sizes are 8-1/2" x 11"~ and
Drawings may be reduced for binding into books. Bar scales shall be shown
on all drawings (See 4.5).
4.3 -Title Block
Titles will be in one. of three formats: Figures, Plates, and Drawings for
the FERC license applicatione
For Figures -See Exhibit 4
For Plates -See Exhibit 5
For License -Later
4.4 -Numbering of Drawings
4.5 -Scales
The principal scales are shown in Acres Standards, Sheets 301-01-11 and
301-01-12.
Bar scales are t.o be either 2 inches or 3 inches long depending on the scale
being represented. The location of bar scales on each sheet is shown on
Exhibit 5.

..
When mora than one bar scale is used on 3 drawing they shall be labeled
Scale A, Scale B, Scale C, etc., with Scale A at the bottom so that the
scale may be identified below the main title of the various views<~
4 .. 6 -Lettering & Line ~vork
The drawings shall be in pencil, with the exception of contours which shall
be in ink. Lettering on the body of the drawing shall be in ink, using
Leroy template No. 140. Letters of views shall be in ink, using Leroy
template No. 200. Drawing titles in the main block shall be in ink, using
Leroy template Noo 200. The proper pen size for each of these is shown on
the template.
4.7 -North Arrow
When it .is necessary to show the direction of north on a drawing, the arrow
shall be placed in the top left-hand corner using Acres standard north arrow
stickers. Unless other criteria dictates, the arrow shall point to the top
of the sheet.
4.8 -Orientation of Drawings
The orientation of drawings shall be such that the direction of river stream
flow will be from left to right or from the top of the drawing. Section
marks will be c.irected to give this orientation. This rule takes precedence
over the direct:i .. on of the North Arrow.
Refer also to Acres Standard 301-01-09. Any deviation from this rul.e must
have the prior approval of the Squad Leader.
4.9 -Dimensioning (See Acres Standard 301-01-12)
Exceptions to the. foot and inch rule are:
. (a) Use engineering scales for site plans, surveys, roads, geotechnical,
and excava·tion drawings. In these cases, all dimensions shall be in
feet and decimals of a foot. The number of places to the right of the
decimal point is determined by the degree of accuracy needed and should
never be greate.r than required.

(b) Elevations on all dra.wings shall be expressed in feet and decimals of a
foot to two places of a decimal.
When decimals are used, the decimal point shall be clearly shown ..
4.10 -General Notes
· Printed general notes, including reference notes and legends, should be
placed at the right side of the drawing above the title block and below the;
key plan (if any). Preferably, general notes shall be placed printed on the
first sheet (or alternatively, the second sheet) of a drawing series.
Reference shall be made on all other ~sheets in the series to the sheet where
general notes are located (i.e., see Sheet of for General Notes).· ----
Where more than one drawing or drawing set is required to detail part
structure, reference shall be made to the other drawing(s) using the
printed label, "THIS DRAWING SHALL BE USED IN CONJUNCTION WITH DRAWING __ •
