011 INSTALLATION OF CONTROL MONUMENTS

PROPOSED WORKS

Under this item, the Contractor shall supply and install control monuments in locations
designated by the City Surveyor.

All monuments are to be inspected by the City Surveyor and must meet City standards prior to
the commencement of field surveying operations. [Sites are to be cleaned up, backfilled
(Standard No. 2700.012), be in proper order and must be stable prior to commencement of
survey work].

All control is required to be both horizontal and vertical. Third order GPS Traversing is to be
used for Horizontal; and second order levelling with a Digital level for the Vertical. The
monuments are to be brass caps supplied by the City. All these requirements are defined
below.

These specifications call for the highest convenient type of instrumentation. Modern
instruments can attain accuracy very easily, and if accurate modern instruments are
competently employed with proper routines to detect blunders, then good accuracy can be
attained without some of the elaborate standards, which may have been required in the past.
This is just as applicable to vertical as to horizontal work. Contractors must design their
observations to isolate any inconsistencies in the existing networks. Location selection,
installation, observation, computation, adjustment and description of City of Mississauga
Control Monuments to be established within City boundaries.

MONUMENTS

All monuments set are to be suitable for Horizontal and Vertical. Any monument set must be
inter-visible with at least one other monument, either new or existing. The only permissible
monuments are the brass caps, shown on Standard No. 2700.011, which are supplied by the
City.

These caps may be set in bridge abutments, substantial box culverts, or other stable concrete
foundations. If there is no suitable structure, then concrete cylinders as shown on Standard No.
2700.012 must be constructed. Caps may only be set in concrete sidewalks if a monument is
required at a particular location, and no other monument would be suitable. Monuments set in
structures must be countersunk so that the top of the cap is flush with the surface; and the
concrete cylinder (Standard No. 2700.00122) may require to be constructed below grades in
some cases. In all cases, the City surveyor must be consulted prior to installing any monuments.

The survey contractor is responsible for obtaining all necessary locates or permissions. All
monuments must be described and referenced on approved City forms, which are digital. The
City will supply station numbers. Although the surveys will not be submitted to COSINE, the
Cosine 9-digit numbering system will be retained.
 SUPPLEMENTAL SPECIFICATIONS

PAGE 15

Monuments may NOT be set in road shoulders or ditches. In rural areas, they should be set as
close to the ROW limit as possible. No monuments are to be set in private property.

STANDARDS FOR GPS TRAVERSING

3A) The following Specifications for third order GPS Traversing are not designed for
submission to COSINE. They are designed to produce coordinates which are as accurate
as the existing network; to show up weaknesses in the existing network; and to guard
against blunders. They are also designed so that the contractor's work can easily be
verified.

1) Any new piece of work must be tied to any existing adjacent stations, and in any
event to at least three stations appearing in the COSINE databank. Every existing
station must be tied to at least two others in closed figures.

All observations, to both new and existing stations, must be part of self-closing
loops so that the new GPS work can be verified independently of the existing
coordinate values.

Practical experience has shown that the most likely source of error is in the set up.
Any new stations must be occupied at least twice, to avoid undetected set up
errors. This may either be as a common station between two sessions, or by a
deliberate repetition. The manner of setting up again at a common station is given
in 3.B below. Heights must be measured and booked with care at the start and end
of each session. Tribrachs must be checked before work is commenced, and at
weekly intervals; and a report to this effect made. It is of no value to "centre"
carefully with an unchecked tribrach. These provisions will be strictly enforced.

Standard No. 2700.013 is an example of an acceptable network,

Acceptable sessions, with four receivers, would be:

AB15 1523 2346 46CD ABCD. This is slightly more than the minimum.

2) The adjustment must verify the existing coordinates. If misclosures greater than
third order standards are obtained, at least an explanation and perhaps more
observations will be required.

3) All bases observed will be less than 15km, and observations shall be Rapid Static. All
baselines observed, both trivial and non-trivial, should be processed, and ambiguity-
resolved solutions obtained for all baselines.

4) Only dual frequency receivers may be employed. Kinematic observations are not
acceptable.
 SUPPLEMENTAL SPECIFICATIONS

PAGE 16

5) All reduced GPS baselines and any other observations must be processed in
GEOLAB; the following least square adjustments are required:
- minimally constrained, which must meet second order accuracy.-fully
constrained in both NAD83 and NAD27(74)

6) The submissions must include:

Raw GPS data Simple log files, showing, for each instrument, for each day’s
work:
- Time of observation
- Station Occupied
- Instrument Height
- Any significant notes

List of sessions:
- Reduced baselinesGEOLAB files;Digital plan of the NetworkReport as to tribrach
checks.
- Report and Analysis

3B) The following is derived, with substantial modifications, but with the same section
numbers, from Part B of the MNR 1994 Specifications. The intention is to preserve as
much of the MNR material as possible.

Some of the material in 3A above is repeated.

1) The following standard least-squares adjustment products are required:

- minimally constrained adjustment, in NAD83
- fully constrained adjustment; all known stations in COSINE held fixed, in NAD83
- fully constrained adjustment; all known stations in COSINE held fixed, in NAD27
- (74)

All adjustments should be in GEOLAB; grid coordinates UTM 17

Values of known stations may be obtained from the City, though most will also be in
COSINE. If there is a COSINE value, the City value will be identical.

2) Third -Order Accuracy: The determination for third order accuracy for all
submissions will be based upon the semi-major axis of the horizontal relative error
ellipse for a point with respect to another point if it is less than or equal to r, at the
95% confidence level, where:

r = 12(d + 0.2), r in cm, d in km.

 SUPPLEMENTAL SPECIFICATIONS

PAGE 17

The assessment of accuracy is dependent upon the covariance matrix from which
the 95% relative error ellipses are determined. The matrix should be scaled by the a
posteriori (computed) variance factor when that value is greater than or equal to
one. This is in accordance with standard practices adopted by the Geodetic Survey
of Canada and MNR, to ensure that the accuracy assessment of a network is not
overly optimistic.

3) Receiver Selection: The receivers selected for the project must be dual frequency
receivers.

4) Trivial and Non-Trivial Baselines: All baselines should be processed from each
session.

5) Scaling of Baselines and Covariance Information: Scaling of individual baselines or

baselines within a session is not permitted. Scaling of the covariance information
from individual baselines or from an individual session is also not permitted. Only
the full covariance matrix as a whole can be scaled by the a posteriori (computed)
variance factor as outlined in Item 2, above.

6) Antenna Siting: If the receiver is to remain at the same station for two or more
observing sessions, the antenna must be re-positioned each time to ensure the
independence of each observing session. This means that for each session the
tripod must be moved and set up again and the GPS antenna plumbed over the
point and re-orientated again. The differences between the instrument heights at
the two consecutive sessions must exceed 10cm. Just moving the tripod leg by 1 cm
and moving the tribrach is NOT acceptable. This repositioning is extremely
important, to avoid mis-centering; and will be strictly enforced.

7) All observations will be in Rapid Static Mode. The occupation time should be
derived on the basis of (5 minutes + 1 minute / km). As an example, for a 10 km
baseline, occupation time should be at least 15 minutes (i.e. 5 + 10 n 15 minutes). A
minimum of 5 (five) satellites is required.

8) Field Logs and Raw Data: A record of what stations comprised each session, with
instrument heights and times of recording, is required. This record should be as
brief as convenient. A complete obstruction diagram is not required All raw GPS
data as gathered by the receivers must be supplied in digital form in order to allow
reprocessing of any or all the data if so required.

9) Ambiguity Resolved (Fixed) Solutions: An ambiguity resolved (fixed) solution must

be obtained for each baseline
 SUPPLEMENTAL SPECIFICATIONS

PAGE 18

10) Station Identification: The 9 digit COSINE number should be employed for all
submissions associated with the project. Raw data, pre-processed baselines, input
and output adjustment files, etc., should consistently reflect this numbering system.

STANDARDS FOR VERTICAL CONTROL

The intention is to do good third order leveling.

1) All work, both loops and closures with listed elevations, must close within
14mm*√K. The choice of 14mm rather than 24mm is deliberate; all previous
Mississauga leveling has been to this standard.

The required instrumentation is:

- A digital level of second order standard, with fibreglass rods,
- Suitable software to download the observations to a text file.
This choice is also deliberate; it will ensure observations of excellent quality, and
eliminate booking errors.

2) Normal precautions for accurate leveling must be taken, e.g: use footplates,
equalize back and fore sights, peg-test the level, avoid grazing rays, ensure that at
least 80% of the rod is read.

3) All lines should either start or close on two points of known elevation (i.e. at least
three known points will be involved). In no case whatever may any part of the new
work be based only on one point. Connections should be made to any nearby
known point.

Standard No. 2700.014 shows an acceptable network. Note that 6 is fixed by a loop;
it would not be acceptable simply to run from 2 to 6 and back. It is supposed that
there is no known point near to 6.

4) All work must be adjusted in a least squares program such as MANORV. This is will
ensure that all observations have been used in a systematic way. The
Manufacturer's software may contain an acceptable adjustment program.

The submissions must include:

-Text file of unadjusted observations, including peg tests.
-Traverse and Loop closures
-Least squares adjustment, with residuals and final coordinates
-Plan of the Network-Report and Analysis
-The full station or benchmark number should be used throughout.

206 CONSTRUCTION SPECIFICATION FOR GRADING

EARTH EXCAVATION

The quantities for this item have been calculated on a cubic metre basis derived from survey
data base and theoretical cross-sections. The excavation items include boulevard, sidewalk,
driveway and road excavation including all asphalt indicated on the contract drawings, and
excavation of asphalt and granular areas back of the proposed curb. It shall also include all
necessary blending works. Excavation for soft spots encountered prior to granular placement
will be paid at the unit rate of excavation multiplied by the measured volume of soft spot
excavation. The unit rate of excavation will be obtained by dividing the lump sum amount bid
for Earth Excavation, by the theoretical cut. Curb, sidewalk, or concrete median slab removal is
not to be included as part of this item but rather is to be measured and included as per OPSS
510.

The theoretical quantity of excavation may be checked by cross-sections to be taken by the

Corporation during excavation and may require slight adjustment to reflect actual excavated
quantities. The only other adjustment to be made from the theoretical quantity based upon
cross-sections taken by the Corporation would be the result of the Project Manager introducing
changes that cause an increase or decrease from the theoretical quantity of excavation. Any
increase or decrease from the theoretical quantity of excavation will be paid at the unit rate of
excavation multiplied by the measured volume of additional or reduced volume of excavation.
The unit rate of excavation will be obtained by dividing the lump sum amount bid for earth
excavation, by the theoretical cut.

The soils report and cross-sections will be made available to the Contractor for viewing upon
request. The native soil has not been tested, analyzed or classified for landfill or lakefill
disposal. It shall be the Contractor's responsibility to find suitable disposal sites for all
excavated materials regardless of haulage distances, dumping fees or the degree of
contamination of the material at no additional cost to the City. The City will conduct limited
chemical testing during their geotechnical investigation on the soil for disposal purposes. The
testing will be limited to common elements of the guidelines and Petroleum Hydrocarbons; F1,
F2, F3 and F4, along with Benzene, Toluene and m/p & o-Xylenes. These results will be
compared to the guidelines set out in the Ontario “Soil, Ground Water and Sediment Standards
for Use Under Part XV.1 of the Environmental Protection Act (2004). If required or requested
the City will conduct additional chemical testing on the soil.

The Geotechnical (Soils) report includes a summary of all subsurface exploration data. This
includes the subsurface profile, exploration logs and ground water information. Where the
borehole logs indicate the presence of shale or rock, it is noted that this data is representative
of the subsurface profile at that location only. Due to the nature of the Shale Strata, subsurface
profile elevations can vary. The logs should be used as a guide only. The contractor shall
satisfy/verify themselves of the actual subsurface conditions. There will be no extra payment
for rock/shale excavation.

In the event that the material changes, the Contractor is required to resubmit the mix design
based on the current material used in the mix, a minimum of four (4) working days prior to
planned paving operations.

ASPHALT PLACEMENT:

The Corporation does not accept cold, longitudinal asphalt joints; therefore the spreader must
be in the process of backing up once the temperature at the start of the joint (day’s paving) is a
minimum of 900C. The Corporation reserves the right to alter the Contractor’s approach to the
job, such that it accommodates the quality of the pavement over the productivity of paving.

Binder courses shall not be placed unless the air temperature at the surface of the road is a
minimum of 20C and rising. Surface courses shall not be placed unless the air temperature at
the surface of the road is a minimum of 70C and rising.

Any roadway greater than 14 meters in width, is to be paved utilizing Material Transfer Vehicles
(MTV's). The through lanes along the roadway shall be paved continuously, in echelon with two
or more pavers. Turn lanes or other lanes must be paved separately with another spreader and
crew, or at a time other than the main-line laneways. The supplier shall be capable of producing
a minimum of 150 tonnes per hour per spreader to ensure paving operation is continuous. All
material shall be delivered to the paving operation within 45 minutes after loading at the plant.
