ENGINEERING SERVICES GEOENVIRONMENTAL CONSULTING SERVICES
TERMS OF REFERENCE
INTRODUCTION/PURPOSE
The City of Guelph is seeking the services of a Geoenvironmental Consulting Engineering firm(s) or
consortia of firms to provide Geoenvironmental services for the proposed Reconstruction Project.
Replacement of underground/surface infrastructure:
The Geotechnical services includes the determination/confirmation of subsurface soil and
groundwater conditions and based on that information, prepare an engineering report with geotechnical
recommendations pertaining to excavation and dewatering, pipe bedding, trench backfill, and
pavement reconstruction for this project. During the field investigation, the consultant is to visually
examine the potential for contaminated or unsuitable materials and conduct further testing/chemical
analysis as required to determine the removal and disposal requirements of the material during
construction. The geotechnical consultant shall:
a) Determine the number and location of boreholes / Monitoring Wells (MWs) to reasonably
reflect existing sub-surface conditions.
b) Contact and coordinate with the Ontario One Call, the City of Guelph, and others, as
appropriate, to mark underground utilities located at the proposed work site, prior to
commencement of drilling activities. Coordinate utility locates for the entire length of the
project and not just the specific BH/MW location.
c) Provide traffic control in accordance with Book 7 of the Ontario Traffic Manual.
d) Collect discrete soil samples (minimum of two samples per borehole) from boreholes based on
the following criteria: soil sample with the highest indication of potential contamination as
evidenced by elevated Photo-Ionization Detector (PID) readings, staining, noticeable odours,
or fill materials. The samples be analyzed by a Canadian Association for Laboratory
Accreditation (CALA) laboratory for Petroleum Hydrocarbons (Fractions F1 to F4) (PHCs);
Benzene, Toluene, Ethylbenzene, and Xylenes (BTEX), Volatile Organic Compounds (VOCs),
Polycyclic Aromatic Hydrocarbons (PAHs), and Metals.
e) Laboratory Soil Analytical Results be compared to the MOE Table 1 SCS for a full depth background
condition and Table 2 SCS for residential/parkland/institutional property use in a potable groundwater
condition.Provisional Item - Conduct groundwater monitoring and sampling from all boreholes
converted into MWs in a manner consistent with the industry standard. Groundwater samples
(one per MW) be analyzed by a CALA accredited laboratory for PHC Fraction F1-F4); BTEX,
VOCs, PAHs and Metals.
f) Provisional Item - Laboratory Groundwater Analytical Results be compared to the MOE Table
1 SCS for all types of property uses and Table 2 SCS for portable groundwater condition in all
types of property uses.
g) Provisional Item - Containerize investigative derived waste (IDW), including both soil and
groundwater, in 45-gallon metal drums (labelled and sealed) for appropriate disposal or
treatment in a licensed landfill facility. Collect composite samples, as required, for waste
2
characterization purposes and have the sample analyzed for Toxicity Characteristic Leaching
Procedure (TCLP) analysis to determine waste classification under O. Reg. 347 (as amended).
h) Identify all borehole/MW locations to be superimposed on design drawings in geodetic format
and UTM coordinates. Geoenvironmental Consultant shall coordinate the BH/MW work with
City staff or the City’s Consultant for the road design so that surveyors can pick up the
locations and elevations of the BH/MW. This information will be provided to the
Geoenvironmental Consultant.
i)
Complete necessary field investigations/testing to prepare an engineering/environmental report
with recommendations pertaining to excavations pipe bedding, ground water control (including
test data for dewatering requirements), trench backfill, roadway construction, pavement
structure and compaction requirements.
j)
Provide treatment recommendation for water disposal, test wells, MWs and piezometers to
determine pumping rates in support of a Permit To Take Water (PTTW).
k) Provisional Item - Consultants to review and assist in completing a PTTW application
including meeting with the MOE staff & City consultant.
l)
Identification of the presence of any potentially contaminated or unsuitable material and
recommendations with regard to further testing including applicable chemical testing. Please
note that this type of issue would be considered unforeseen and a reasonable cost for testing
would be considered.
m) Provide $5M liability insurance and required documentation in support of road occupancy
permit that is required for drilling.
Final Documentation
1. Three (3) hard copies of the completed geoenvironmental investigation report for each road
section.
2. One (1) digital copy of the completed geoenvironmental investigation report in PDF format to
be provided on a CD prior to the tender.

Standards (OPS) materials.
•
Based on the testing results, the report shall provide a recommendation relating to the
suitability of the in-situ material being used for Granular A and B.
3
•
Standard Proctor Moisture Density Test Results.
•
Discussion and recommendations, when applicable, for excavation and dewatering, bedding for
storm sewers, ground water control, trench backfill, roadway construction, pavement materials,
thicknesses, and compaction requirements.
•
Geoenvironmental Consultant shall co-ordinate their work and co-operate fully with other
consultants on the site.
•
The geoenvironmental report shall be part of the contract documents.
•
The consultant should note that the City will provide a Civil 3D drawing file for their use. The
City will provide a base plan at the beginning of the project for the installation of the BH/MW’s.
Once the BH/MW’s have been installed, the Geoenvironmental Consultant shall coordinate
with City staff to ensure that the locations and elevations of the BH/MW’s are surveyed and
added to the Engineering drawings. A copy of the Civil 3D drawing file of the proposed works
