REPORT TO THE GENERAL PURPOSE AND ADMINISTRATION COMMITTEE
MEETING OF MARCH 22, 1982.
REPORT NO. WD-22-82.
SUBJECT: 1982 NEEDS STUDY UPDATE.
RECOMMENDATION:
v It is respectfully recommended:
1 . That this report be received, and;
2. That Totten Sims Hubicki Associates Limited be retained
to undertake the 1982 Needs Study Update, in accordance
f'a with the guidelines of the Ministry of Transportation
r & Communications, at an upset limit in the amount of
$2,500. 00 (Two Thousand Five Hundred Dollars) .
BACKGROUND AND COMMENT:
In order to establish allocations for construction and mainten-
ance, the Ministry of Transportation & Communications requires
the Municipality to annually update the Road Needs document.
In 1980 the Town retained Totten Sims Hubicki Associates Limited
to revise the original 1975 Road Needs Study into the metric
mode and, subsequently, the resulting document was revised in
early 1981 .
Although it is not essential that the Town employ a consultant
for this work, so far as the Ministry is concerned, it is of
advantage to Staff as time limitations and general workload would
not allow the update to be completed prior to the submission
deadline of June 1 , 1982. The fees associated with the services

WD-22-82 - 2 _
are subsidizable at the rate of fifty per cent (50%) and the
Consultants have indicated that the work will be completed for
the amount of $2,500. 00.
It is suggested that the Town request Totten Sims Hubicki to
complete the necessary update, at the earliest possible date,
and that the expenditure for same be applied against Account
No. 7204-0247-00035-3, in accordance with the Budget allowance.
Respectfully submitted,

Dear .Sir:
Re: Road Needs Study Annual Update - 1982
As you know, the 1982 construction and maintenance alloca-
tions for your municipality were based on your road needs
information. To ensure that your 1983 allocation is based
on correct data, it is necessary to update the road and
bridge needs appraisal information.
The update procedures are outlined in the Methods Manual -
Municipal Roads Systems - Needs Measurements - pages 32 to
40 . The attached memorandum details some of the key
elements of the update which should be used to complement
the procedures described in the Methods Manual.
There have been some minor changes to the Methods and
Inventory Manuals. The revised pages are contained in the
enclosed attachment and should be included in your copy of
the manuals and used in your update.
It is not necessary to retain the services of a Consulting
Engineer if you and/or your staff can carry out the update.
For municipalities operating on an "urban" basis for road
work, the cost of the work involved in updating the Road
Needs Study by municipal staff will be part of the 7%
administration and overhead allowance. If Consulting
Engineers are retained the services will be subsidized
directly as a road maintenance expenditure.
For municipalities operating on a "Rural" basis for road
work the cost of the work involved in updating the Road
Needs Study will be considered as a road maintenance
expenditure and will be eligible for subsidy at the normal
road rate.
. . .2
2
Ministry staff will be available to provide assistance
by answering any questions you may have and to participate
actively in the update procedures as required.
THE DEADLINE FOR COMPLETION OF THE 1982 UPDATE IS JUNE 1, 1982,
HOWEVER, AN EARLIER SUBMISSION WILL BE APPRECIATED.
If you have any questions regarding any portion of the update,
please do not hesitate to contact our District staff.
Yours very truly,
Moffat,
Manager,
Municipal Roads Office.

CHANGES IN THE JANUARY, 1982 PRINTING
OF THE MANAULS
The "Methods Manual " and the "Inventory Manual " were reprinted this month
with some minor updates.
METHODS MANUAL
Some minor typographical errors and/or wording were changed on pages IV, V,
and 61 .
Please replace page 14 with the attached copy, and insert on pages 34 and
35 the underlined text as shown below:
Page - 34 -
Inventory Data Reports
As soon as the sheets are received from the municipalities the data will be
screened and coded. Any changes to the sheets will be discussed and cleared
with the municipality. Up-to-date print-outs of the various inventory and
accomplishment summary reports will be forwarded to the counties or regions
and to the municipalities in the Large Lower Tier Program by September of each
ear.
Page - 35 -
(c) Additions or Deletions of Roads and Structures
All new roads and structures, where the municipality has provided maintenance
services prior to January 1 , must be recorded on an appraisal sheet and given a
road section or structure number. The road section and structure location shoul
be recorded on the road section or structure maps. Any roads or structures
deleted from the system shall have the appraisal sheet removed and the road
section or structure map adjusted accordingly. Inhere new roads cross a railway
track, the appropriate information should be recorded on the railway crossing
summary sheet and the crossing location shown on the railway crossing map.
Appendix F-1 and F-2 (pages 65 and 66) were also changed, but only apply to
Upper Tier municipalities.

5. ENVIRONMENTAL CONSIDERATIONS
Where application of the criteria for upper-tier roads results in the proposed
extension of an existing road or the construction of a new road, and where
required improvements of existing links due to an upward change in function
and/or an increase in traffic volumes is necessary, consideration should be
given to the environmental impact in the service corridor.
If the proposed road extensions and/or new road improvement are required in the
NOW or 1 to 5 YEAR PERIOD, the municipality should include an adequate in-
vestigation of any significant environmental condition changes with the pre-
liminary design phase of the project.
In cases where a significant environmental change is clearly identified , the
link in question may have to be re-evaluated with respect to inclusion in
the upper-tier system and perhaps alternate links considered.
6. PHYSICAL INVENTORY AND IMPROVEMENT COSTS ESTIMATION
Identification of desirable upper-tier roads is required before physical
inventory is taken. All roads under the jurisdication of the study municipal-
ity and any desirable additions must be inventoried_
Appraisals of structural adequacy of the road system shall be carried out by
the municipality' s engineer or road superintendent, the Consultant and the
district municipal engineer or his designated alternate. The point rating
and appropriate type of improvement shall be decided at this time.
In local roads needs studies, arterial and rural roads will be inventoried in
detail . In the urban environment, most roads below the arterial classification
will be appraised using a modified inventory technique.
An inventory of individual alleyways is not required. However, an appraisal
sheet should be prepared showing the total kilometres of alleyways eligible
for maintenance subsidy. These alleyways must meet all four of the following
conditions:
(a) alleyway is wide enough for two cars to pass - platform width on gravel
roads or surface width on hard top roads must be 5.0 metres or greater.
Where alleyway width is varied, at least 50% of the length must meet
this criteria
(b) alleyway is continuous through a block
(c) alleyway is common and public way accessible to the general public
(d) alleyway functions as an alternative to a local street - servicing
business sections or off-street parking lots
Note: Alleyways that function as access to the rear of residential lots
(i .e. serving as an entrance to rear garage or for collection of
garbage) are not to be included.
The method of carrying out the detailed and modified physical inventory is
specified in the "Inventory Manual - Municipal Roads and Structures". The
latest edition must be used. Any questions on inventory should be directed
to one of the Ministry's representatives on the Co-ordinating Committee.
INTRODUCTION
This manual has been prepared to provide a uniform method of evaluating the
more important physical and service characteristics of all types of roads
and structures under, or in some cases affecting, municipal jurisdictions,
and of estimating the type, cost and priority of the work required to improve,
to an appropriate standard, those roads, streets or structures which are
critically deficient now, or which are estimated to become so within the ten-
year study period.
Road sections and structures under construction on the OFFICIAL INVENTORY
DATE shall be appraised as being completed. Study municipalities will be ad-
vised of the OFFICIAL INVENTORY DATE before the appraisal is carried out.
Annual updates' official inventory date is January 1st of the update year.
Most general conditions are covered but where unusual circumstances are en-
countered, ENGINEERING JUDGMENT SHOULD BE APPLIED AND A SUITABLE PROCEDURE USED,
even though it may vary from that described in the manual . When in doubt as
to the applicability of any procedure to a particular situation, do not
hesitate to contact the representative of the Ministry.
The requirements for completing the various items on the appraisal sheets are
the same in many cases but, in others, vary according to the type of study
(i .e. County/Regional , Local , Township, etc. ) and according to the type of.
section or structure (i .e. Rural , Semi-Urban or Urban) . Definitions of
section and structure types will be found on pages 1 and 51 respectively.
WHEN NEW ROADS OR NEW STRUCTURES ARE RECOMMENDED, THEY MUST BE FULLY
JUSTIFIED AND JUSTIFICATION REPORTS AS OUTLINED ON PAGES 41, 43 and 77,
AND MUST BE SUBMITTED FOR EACH OF THEM. SEPARATE APPRAISAL SHEETS SHALL
ALSO BE SUBBITTED WITH THE APPROPRIATE INFORMATION FILLED IN AS INDICATED IN
THE "IDENTIFICATION" AND "TYPE, COST & TIME OF IMPROVEMENT" BLOCKS. IN
ADDITION, AN ESTIMATE OF THE VOLUME OF TRAFFIC (AADT) WHICH WILL USE THE NEW
FACILITY UPON COMPLETION MUST ALSO BE GIVEN.
APPRAISAL PROCEDURES
Municipal Road Section Appraisal Sheet (Form OD-MB-175M) shall be used for the
inventory data of all roads (See page 50/A).
Municipal Structure Appraisal Sheet (Form OD-MB-176M) shall be used for the
inventory data of structures (See page 84/A).
A Railway Level Crossing Appraisal Sheet (Form OD-MB-177M) has been introduced
to record road/railway crossing information (See page 96).
(v)
STORM SEWER DEFICIENCY ON NON-DEFICIENT ROADS
Item 63, on the road appraisal sheet, refers to the adequacy of the existing
storm sewers or the need to provide storm sewers where none exist. The
criteria determining the acceptability of a stc:.rm sewer deficiency should be
read very carefully. Storm sewer deficiencies WALL NOT be accepted without
a drainage report justifying the need.
BOUNDARY ROADS AND BRIDGES
For the purposes of a roads needs study the following criteria will apply to
boundary roads and bridges.
A A BOUNDARY ROAD is any road which is located on a boundary line (either
on the centre line of the road or on either side of the right of way) or
which may deviate from the boundary due to physical obstructions.
• A BOUNDARY BRIDGE is any structure which is located crossing a boundary
line or on a boundary road described above.
BENCH MARK COSTS
The Bench Mark Costs established for each municipality in the program are
tabulated on a form as contained in Appendix "F" and should be reviewed
carefully prior to preparing the Appraisal Sheets.
SPECIAL REQUIREMENTS FOR COUNTY OR REGIONAL ROADS NEEDS STUDIES
In this part and throughout the manual "region" should be considered synony-
mous with "county".
The appraisal shall include all existing roads wholly or partly under county
jurisdiction and all roads under local jurisdiction which are identified as
desirable county roads. In all cases the minimum tolerable county road
standards shall be used.
Where the desirable county road is under the jurisdiction of a local
municipality which is included in the Large Lower Tier Program and has avail-
able the road or structure information, the County should contact the Ministry' s
Municipal Roads Office or the municipality to obtain copies of the completed
appraisal sheets thereby eliminating a duplication of effort. The road in-
formation, needs and costing prepared under the local municipality should not
be altered when added to the County' s desirable system.
(36)
B. HARD TOP SECTIONS /
(a) If the point rating assigned is 7 or less, check under
"critical deficiency" as NOW.
(b) If the point rating assigned is between 8 and 11 inclusive, and
the structural adequacy is expected to deteriorate, indicate
deficiency in the one to five year time period.
(c) If the point rating assigned is between 12 and 14 inclusive,
and the structural adequacy is expected to deteriorate, in-
dicate deficiency in the six to ten year time period.
(d) If the point rating assigned is 15 or more, no critical
deficiency is considered to exist. Check under NOT DEFICIENT.
DO NOT WRITE ANYTHING IN THE CODING BOX.
ITEM 63 STORM SEWER ADEQUACY
A Storm Sewer deficiency noted here may occur on both deficient and
non-deficient roads. Storm sewer improvements on deficient roads
shall be costed along with the recommended improvement to eliminate
the road deficiency identified. Storm sewer improvements on non-
deficient roads may include costing for road reinstatement or
complete reconstruction as the case may be.
A. RURAL SECTIONS - Spare. Do not fill in.
B. SEMI-URBAN AND URBAN SECTIONS
(a) Flooding Conditions
A Storm Sewer deficiency may be recorded in the NOW or 1 to 5 YEAR
time period for the following reasons PROVIDING FLOODING OCCURS ON
AN AVERAGE OF ONE OR MORE TIMES PER YEAR, THE SOLUTION TO ELIMINATE
THE FLOODING IS PRACTICAL AND IS DOCUMENTED IN A DETAILED DRAINAGE
REPORT CONTAINING THE PROBLEM AREA:
(i ) On Semi-Urban road sections without storm sewers when the
road becomes impassable.
(ii ) On Semi-Urban road sections with storm sewers when a Local
Road is completely flooded (water over the entire surface)
or an Arterial or Collector Road is flooded more than 50%
of the width from edge of pavement to the centre line.
(iii ) On an Urban road section when a Local Road is completely
flooded (water over the entire road) or an Arterial or
Collector is flooded more than 50% of the width from the
edge of pavement to the centre line.
(iv) Where surcharging in an existing storm sewer or sanitary
sewer results in flooded basements.
(36/A) C�
(b) Non-Flooding Conditions
Where storm sewer improvements are proposed on areas which
do not experience flooding conditions, consideration will
be given to include the needs in the NOW or 1 to 5 YEAR
time period if details are provided in a drainage report
and the municipal council have given approval in principal
to do the work.
(c) Off-Take Storm Sewers or Open Ditches
Off-Take Storm sewers or open ditches, or a combination of both, to
the appropriate outfall can be included in the drainage costs. This
cost will be on the appraisal sheet where the off-take occurs and
should be identified separately from any storm sewer cost. Where
the pipe exceeds 525 mm, the usual formula applies to determine the
amount eligible for subsidy. The ditch cost eligible for subsidy
will be based on the same percentage for the last section of storm
sewer leading to the drainage ditch.
ITEM 64 DO NOT WRITE ANYTHING IN THE TWO "ACCOMPLISHMENT CODE" BOXES.

GEOMETRIC DESIGN STANDARDS
FOR RURAL ONTARIO ROADS
Use D.H.V. for design
* The 1.0 m shoulder width is considered the minimum desirable width for
pavement support. This may be reduced to 0.5 m when paved.
* The 2.0 m shoulder width is considered the minimum acceptable for a
disabled vehicle.
- These cross-sections are desirable standards. An acceptable standard
formed by a variation of (+) one increment may be considered, with the
appropriate approval .
- a if number of trucks > 10% increase by one increment
b if number of trucks > 15% increase by one increment
e if number of trucks > 25% increase by one increment
Lane width increments - 0.25 m
Shoulder width increments - 0.50 m
d 0.5 m shoulders will be permitted where there is no foreseeable possibility
of the road being paved within a 20 year period. (Note: 1.0 m shoulder
must be used where guide rail is installed. )
- When curb and gutter is used in conjunction with a paved shoulder the
gutter pan forms part of the paved shoulder.
- Lane widths for Multi-lane highways shall be 3.75 m in all cases except:
i ) 4-lane divided or undivided with design speed less than 100 km/h
where the lane width shall be 3.5 m. In rural fringe areas where
urban development is likely within the life of the highway, rural
cross-section of 1 .0 m flush median , 2 x 3.75 m driving lanes and
0.5 m of full depth construction partial width paved shoulders
should be considered where 4 lanes are required. (This 17 m
cross-section provides for a 3.0 m continuous left turn lane with
3.5 m driving lanes.)
ii) 6 or more lanes divided , all design speeds , the median lane shall
be 3.1J m.
- The median shoulder on 4 lane divided highways shall be 1.0 m and paved.
- The median shoulder on divided highways with 6 or more lanes shall be
2.5 m except where 6 m medians or less are used.
Auxiliary Lanes
- Left turn lanes with no median strip are to be 0.25 m less than the width
of the adjacent through lane, minimum 3.25 m.
- Left turn lanes with median strip (painted, rippled or raised) shall be
3.0 m exclusive of gutter or curb offset. The curb face on all raised
medians adjacent to left turn lanes must be offset.
-2- Attached to Directive C-63
(100%A)
/Attachment No. 2
- Continuous left turn lanes shall be 4.0 m desirable, 3.0 minimum. The
minimum standard should normally only be utilized where operating speeds
are less than 60 km/h except where a future eventuality is being protected.
- Right turn lanes and acceleration lanes are to be 0.25 m less than the
width of the adjacent through lane, minimum 3.25 m.
- Truck climbing lanes and passing lanes are to be 0.25 m less than the
width of the adjacent through lane minimum 3.25 m. The adjacent shoulder
should desirably be the same as that on the approach roadway but may be
reduced to a minimum of 1.0 m where significant economies can be demonstrated.
Ramps
Single lane interchange ramp widths shall be 4.75 m.
Multi-lane interchange ramps shall have lane widths of 3.75 m except
where pavement widening for curves is required.
The right-hand shoulder on single and multi-lane interchange ramps shall
be 2.5 m.
Left-hand shoulder widths on interchange ramps shall be:
i) zero on single lane ramps, an effective shoulder will be formed by
insetting the pavement edge line see DD-213, 214 A and B.
ii ) zero on multi-lane ramps with curb and gutter see DD-215 B.
iii ) 0.5 m on multi-lane ramps with no curb and gutter see DD-215 A.
Right-hand shoulder widths adjacent to speed change lanes shall be 1.0 m
except for channelized intersections where the lesser of the shoulder
widths on the two approach roadways shall be continued throughout the
speed change lane and channelized ramp, or in the case of interchanges
where the ramp shoulder width shall apply.
Rounding
- Shoulder widths do not include rounding. Rounding, when applied, shall
be:
i ) 0.5 m when design speed < 100 km/h
ii ) 1.0 m when design speed > 100 km/h
- Rounding on the left-hand side of single lane interchange ramps having
no shoulders shall be 1.0 m.
Medians
- Flush medians - 1.0 m.
- Raised division islands usually associated with intersections - 2.0 m.
- Raised medians intended to accommodate left turn storage lanes within the
median - 5.0 m.
-3- Attached to Directive C-63
(100/s)
,;�hment No. 2
- The minimum basic median cross-section for use on freeways in urban areas
shall consist of a 6.0 m median utilizing a concrete median barrier.
Bridge piers shall be accommodated in accordance with DD-918-C.
- The standard median width for rural, freeways will be 20 m except as noted.
This 20 m median provides for an additional lane of 3.5 m in each direction
with a resulting 13 m depressed median. The subsequent addition of 3.5 m
lanes in each direction would result in the standard 6 m urban cross-section
(see Figure 1).
- Exceptions to the standard value of 20 m should be justified but may
include:
i ) conditions where construction staging may include at-grade
intersections.
ii ) locations where terrain or property costs are such that independent
alignments are appropriate.
Under these conditions the basic median widths should be based on increments
of 5 m.
- Median widths designed for multiple use, including transit systems,
should be designed on a project specific basis in conjunction with the
Highway Design Office.

1982 UPDATE PROCEDURES LARGE LOWER T IV
INTRODUCTION FEB 1`� 1982
An update of the needs information is required to ensure that
the deficiency ratings of the roads and bridges (including
Highway Connecting Links) shown on the appraisal sheets represent
the condition of the road system as of January 1, 1982 .
Municipalities using their own staff to carry out the update
can complete the following items prior to undertaking the
spring structural adequacy review.
- 0 Appraisal sheets with carry-over costs should
have the costs removed or reduced as the case
may be. See enclosed Report 2 - Roads and
Report 4 - Bridges which list the carry-over
costs in the "Now" period.
• New roads, including subdivision roads where
winter maintenance has been done, require
appraisal sheets.
® New bridges require an appraisal sheet complete
with photographs.
® Where improvements were carried out on roads
and bridges in 1981, the appraisal sheet should
be revised to reflect the changes or a new
appraisal sheet should be prepared. Improvements
i
are to include all changes resulting from
construction, resurfacing, spot improvements
and drainage work.
Minor changes can be noted separately on a
xerox copy and the changes to the original
appraisal sheet will be done by the Ministry.
The type of minor changes include, time period
changes, traffic updates which do not affect
design changes, etc.
® Any known errors and/or omissions can be
corrected.
General update procedures are outlined in the "Methods Manual"
- Municipal Road Systems - Needs Measurement" on pages 32 to 40.
The following paragraphs detail some of the key elements of the
update .
1. Classification
Any classification changes should be identified. If the pro-
posed change affects those roads identified as "Upper Tier"
(see Item 19 - Inventory Manual) or are proposed as "Upper Tier"
roads they must be accompanied with supporting documentation
for approval by the Ministry.

2 . Additions or Deletions of Roads and Structures
All new roads and structures assumed by the municipality
prior to January 1, 1982 or where winter maintenance has
been carried out by the municipality must be recorded on
an appraisal sheet and given a road section or structure
number. The road section and structure location should be
recorded on the road section or structure maps. Where new
roads cross a railway track at grade, the appropriate
information shoul be recorded on the railway level crossing
appraisal sheet and the crossing location shown on the rail-
way crossing map.
3. Carry-Over Costs
For road sections and structures that were wader construction
in 1980 with carry-over costs, the appraisal sheets should
be revised appropriately to remove or reduce the cost shown
(see enclosed computer output data) . Where, for some reason,
the carry-over costs are not reduced, a brief explanation
must be provided.
Road sections or structures where construction began in 1981
should be revised to show the final design elements and, if
not completed, the outstanding amount as of January 1, 1982
shown as "carry-over" cost.
4
4. Alleyways
Appraisal sheets of alleyways must be reviewed to ensure
that they meet all 4 conditions (see revised page 14 -
Methods Manual) . Those alleyways which meet the revised
criteria are to be combined onto one appraisal sheet. This
data is required for maintenance subsidy only, therefore,
no construction cost should be shown. Those alleyways
that do not meet the revised criteria must be deleted
from the inventory.
5. 1981 Construction Projects
Where 1982 construction is scheduled, final design costs,
if they are available, should be shown on the appraisal
sheets and noted under remarks.
6. Traffic Update
Only those road sections and structures where traffic volumes
are significantly different from those on the appraisal sheet
should be provided. If your municipality has carried out
a traffic operation or transportation study, the traffic
volumes should be checked with those on the appraisal sheets
to see if they should be updated.

7. Structural Adequacy Review - Spring Break-Up 1981
It is necessary to review all roads in the 1 to 5 year period
to determine if they have further deteriorated to be con-
sidered a NOW need. Other road sections in the 6 to 19 year
period or non-deficient roads where it is suspected that
the structural condition of the road has deteriorated
sufficiently to be included in the NOW or 1 to 5 YEAR
needs should also be appraised. The structural rating should
also be adjusted and the type of improvement and cost recorded
in the appropriate time period.
Where a single lift of hot mix resurfacing has been under-
taken as a temporary improvement to roads which were identified
as structurally deficient in the NOW or 1 to 5 YEAR period,
the structural rating shall be raised to a minimum of 13
and the type of improvement and cost moved back to the 6
to 10 year period or removed completely. Where the single
lift of hot mix resurfacing has been undertaken on roads
which were identified as structurally deficient in the 6 to
10 year period, the structural rating shall be raised to a
minimum of 15 and the deficiency and cost removed from the
appraisal sheet.
Where single or double surface treatment has been under-
taken on structurally deficient roads it will not necessarily
alter the structural rating or type of improvement.
Any improvement costs over and above the established bench
mark costs should be determined at the time of the field
investigation and noted on the appraisal sheets under
"Remarks" .
All roads where the structural rating has been altered
and results in an improvement cost being added or moved
into a new time period MUST BE REVIEWED AND APPROVED BY
M.T.C. DISTRICT.
8. Proposed Major Roads
All proposed major roads eligible for subsidy must have a
"Main Thoroughfare" designation before an appraisal sheet
and estimated cost can be included in the municipality' s
roads needs.
Requests for "Main Thoroughfare" designation must be made
through the M.T.C. District Office and, if approved, the
costs may be included in the 1 to 5 year needs.
9. Storm Sewer Needs
The 5 year storm sewer program must be updated to show
completed projects, projects started with carry-over costs
and the addition of new projects now included for 1987 .
These revisions must be approved by M.T.C. District
representatives and accompanied by a copy of the Municipality' s
5 year capital works program and storm sewer improvement map.
10. Partial Improvement on Deficient Road Sections
In cases where a road or group of roads shown on an appraisal
sheet as deficient and have only had a portion of the
road or roads improved, the following methods may be used
to update the appraisal sheet:
(i) Where the improved portion of road is less
than 50% of the total length then the length
to be improved (Item 67) and the improvement
cost (Items 77 & 79) should be reduced
accordingly.
Where the improved portion of road is more than
50% of the total length, the appraisal sheet should
be revised to show a non-deficient road and the
portion of road still deficient costed as a spot
improvement.
Where road sections are improved to different
standards, i.e. urban section from a semi-urban
standard, the improved section could be added
to another appraisal sheet of similar standard
in the same geographic location with the appropriate
changes in kilometres (reduction on one and
addition on the other) or a new appraisal sheet
should be prepared for the improved section.
tY
(iv) Where road sections are altered either by
additions or deletions of the section limits,
a cross reference must be made to all sections
with changes. This would eliminate any
duplications or omissions.
11. Partial Deterioration on a Non-Deficient Road Section
The deterioration of a portion of road shown on an appraisal
sheet as non-deficient could be treated in a similar manner
as in 10 above.
12. Improvement Costs
All identified deficiencies shall have the appropriate
improvement noted and the estimated improvement cost shown
on the appraisal sheets.
ALL COSTS ESTIMATES SHALL BE BASED ON THE APPROVED 1979 BENCH
MARK COSTS.
13 . Maps
It will be necessary to provide the Ministry' s District
and Head Offices with maps, showing clearly, all changes
resulting from the update.

General Comments
Any errors and/or omissions in the information collected in the
original study should be corrected and forwarded to the District
Office as part of the update material.
It should be noted that the update procedures described in the
Methods Manual and in this attachment apply in most cases.
There will be instances where the criteria do not apply and
in these circumstances "Engineering Judgement and Common Sense"
should be used.
Those municipalities which operate on a "Rural" basis are
required to update the equipment and housing to reflect their
5 year needs to 1987.
Upon Ministry acceptance of the updated information, the data
will be computerized and a revised set of "Summary Tables"
will be sent to the municipalities for their information.
Where the Municipality has undertaken the update, only the
revised or additional appraisal sheets need be forwarded to
the Ministry. Where a new bridge has been constructed, 4
copies of the photography are required. The Ministry will
provide copies for the municipality and the District and
Bridge Office.
Where consultants have been retained to carry out the update,
copies of the changes are required as follows:
® Original Appraisal Sheets to Municipal Roads
Office
® Copy to Ministry's District Office
® Copy to be retained by Municipality
0 Additional copy of structure appraisal
sheets only to Ministry' s Bridge Office
All updated or new structure and railway-level-crossing appraisal
sheets shall have original photographs attached. Xerox copies
of photographs are not acceptable.
Ministry staff will check all appraisal sheets for major errors
and omissions. If necessary, .a meeting will be arranged to
discuss any necessary changes prior to computerizing the informa-
tion.
