CAIS PREAMBLE
1.0 INTRODUCTION
The Construction Administration and Inspection Task Manual (CAITM) was introduced in the 1990’s
for the purpose of assisting the Contract Administrator (CA) and inspection staff with the
administration of highway construction contracts for the Ministry of Transportation Ontario (MTO).
The scope and layout of the original CAITM remained unchanged from its inception until its last
revision in 2020.
In 2019, MTO began a comprehensive review of the CAITM which led to the development of the
new Construction Administration and Inspection Specifications (CAIS) which replaces the former
CAITM in its entirety.
The Contract Administrator is responsible for providing Contract Administration services and
deliverables. The Contract Administration requirements are specified in the Construction and
Administration and Inspection Specifications (CAIS). The CAIS form part of the Contract
Administration contract.
The CAIS provide instructions to the Contract Administrator. For the purposes of the CAIS, this
includes all staff delivering administration and inspection services and deliverables as part of the
Contract Administration duties.
The CAIS outline the requirements from the time of awarding the Contract Administration contract
to the submission of the final deliverables.
The CAIS are structured to align with existing Ontario Provincial Standard Specifications (OPSS)
and MTO Standard Special Provisions (SSP) divisions. The CAIS includes:
· CAIS 100 - MTO Construction Administration General Conditions which aligns with:
o Division 1 - OPSS 100 - MTO General Conditions of Contract Specification
The CAIS also reference CAIS meeting templates and checklists. Further information about CAIS
meeting templates can be found in CAIS 100, section CAGC 2.0, Project Management, and further
information about CAIS checklists can be found in CAIS 100, section CAGC 6.0, Management of
Deliverables.
The CAIS focuses on the requirements of the Contract Administrator and is not meant to replace
procurement-related requirements, or include provisions about Contract Administrator staff
qualifications, or contractual payment mechanisms, or replace the Contract Administration
contract’s Legal Terms and Conditions.
To help users understand what the CAIS is and is not, the principles below were developed. These
principles were created during the CAITM Review and were supported by stakeholders and MTO
decision makers.
The future intent is to include the CAIS in CA contracts, in a manner similar to the way OPSSs and
SSPs are included in construction tenders (i.e., referenced by specific numbers and revision dates).
1. To identify to the CAs, inspectors, and MTO staff standard duties to perform and when to
perform them.
2. A provincial contractual standard.
3. A valuable standard for the basis of CA performance monitoring.
4. A set of instructions for construction administration and inspection work.
5. The only MTO reference for construction administration and inspection work standards.
6. Intended to be used by internal and external staff.
7. Includes work for design-build and design-bid-build Contracts.
8. Include all standard / typical work.
9. To contain administration activities that will be separate from inspection activities.
10. To be publicly available.
11. A fluid and flexible product governed by these principles and a set framework.
12. To be consistent with other MTO policies and manuals.
The CAIS are published in a manner similar to OPSSs i.e., published as individual documents with
specific revision dates for reference purposes, and also compiled into a complete manual (CAIS
manual) for ease of use.
CAIS 100, contains the MTO Construction Administration General Conditions (CAGC) which covers
the general requirements for the Contract Administrator during the pre-construction, construction,
and post-construction phases. CAIS 100 shall be read in conjunction with all other CAIS.
The remaining CAIS contain administration and inspection activities applicable to various general,
construction, and material components of the work as specified in the corresponding standard
specifications and/or special provisions. For example, CAIS 919-0 outlines the Contract
Administrator’s administrative and inspection requirements for OPSS.PROV 919.
CAIS for administration and inspection activities are structured similar to standard specifications
and special provisions. For example:
The requirements in the CAIS are separated into clearly defined tasks for:
The definitions of “Administrative Activities”, and “Inspection Activities” are provided in CAIS 100,
MTO Contract Administration General Conditions (CAGC), section 1.0, Definitions.
All CAIS for administration and inspection activities shall be read in conjunction with CAIS 100.
Applicable Provincial functional offices will develop corresponding CAIS for use with all standard
specifications, standard special provisions, and Head Office non-standard special provisions. The
CAIS and related specifications will be updated and revised as necessary in conjunction with one
another.
Construction contracts that contain locally and/or regionally modified specifications, may require the
modification of existing standard CAIS and/or the development of new project specific CAIS, by the
design team. The CAIS shall be modified and/or developed in accordance with the “How to Write a
CAIS” guidelines, and in consultation with Regional and/or Provincial functional team
representatives, the Contract Services Administrator (CSA), and the Contract Management Office.
The CAIS are published on the MTO Technical Publications website. Other Ministry Documents,
Manuals and Guides to be used for Administering Ministry Contracts include:
a) WBCMS Guides
b) CSA Guidelines
c) QAO Guidelines
d) Seeding Manual
e) Manufacturer inspection guides
f) Field Guide for the Acceptance of Hot Mix and Bridge Deck Waterproofing
g) Contractor Performance Rating System Guide
h) Construction and Maintenance Change Order Manual
i) Progress and Final Payment Quantities Guidelines
j) Information and Compensation Requests and Dispute Resolution Manual
k) Occupational health and safety guide
l) MTO policies
In general, MTO manuals, guides, memoranda, forms, and other technical documents are available
from the MTO Technical Publications website.

Design-Build Submission
Instruction Notices and Notice of Non-Conformance
Suggested wording:
“The Ministry is in receipt of your submission for <insert specifics>. A non-conformance has been
identified and a Notice of Non-Conformance is attached. <remove preceding sentence if not
applicable; attach Notice of Non-Conformance if applicable>. The Ministry will not be approving the
design submission since, as identified in the Contract Documents, the Design- Builder is solely
responsible for design adequacy, accuracy, constructability, appropriateness regarding
environmental requirements and conformance to all requirements of the Work.”
Send an additional Instruction Notice once the review is complete. Suggested wording:
“The Ministry has reviewed your submission for <insert specifics> for conformance to the Contract
Documents. A non-conformance has been identified and a Notice of Non- Conformance is attached
<remove preceding sentence if not applicable; attach Notice of Non-Conformance if applicable>.
The Ministry will not be approving the design submission since, as identified in the Contract
Documents, the Design-Builder is solely responsible for design adequacy, accuracy,
constructability, appropriateness regarding environmental requirements and conformance to all
requirements of the Work.”
Include the “non-conformance” statement in the appropriate Instruction Notice above and issue a
Notice of Non-Conformance. Suggested wording to be included in the Notice of Non-Conformance:
“In the opinion of the Ministry the submission for <insert specifics> is not in conformance to
requirements of the Work for the following reasons:<insert specifics of non-conformance including
documentation, photos, etc. as appropriate> As identified in the Contract Documents, the Design-
Builder is solely responsible for design adequacy, accuracy, constructability, appropriateness
regarding environmental requirements and conformance to all requirements of the Work. When, in
the opinion of the Ministry, the design submissions are not in conformance, or contain significant
errors, the Design-Builder will be required to correct the Work so that it conforms to the Contract
Documents. The Design- builder shall stop construction of the Work that is not in conformance with
the Contract Documents or any Work which may impede the correction of Work that is not in
conformance with the Contract Documents, until such time as the Design-Builder corrects the Work
so that it conforms to the Contract Documents at no cost to the Ministry.”
For the purpose of the CAIS, the abbreviations shall be as specified in OPSS 100.
For the purpose of the CAIS, references to the masculine or singular shall be considered to include the
feminine and the plural, and vice versa, as the context requires.
For the purpose of the CAIS, defined terms appear as capitalized words, and the definitions shall be as
specified in OPSS 100, as specified in referenced documents, and as follows:
Administration Activities means actions that need to be performed in order to support the completion of the
work and the inspection of the work. These activities do not usually require attendance at the work site to be
completed (e.g., reviewing drawings, plans, test results, notifications, etc.)
Check means to confirm that the Work conforms with the Contract. When the Contract requirements are not
met, the Contract Administrator shall use the appropriate administrative actions including instruction notices,
non-conformances, deviations, infraction reports, warning of infractions, contractor performance rating
assessment. To make sure the proper assessment is made when determining Contract conformance, the
Contract Administrator shall conduct the necessary inspections.
The Contract Administrator shall refer to applicable specifications and/or special provisions (as referenced in
each CAIS) to confirm Contractor Compliance.
Check shall also mean to record Contract deficiencies, ensuring that all information/findings are also be
documented in the diaries, and informing the Contractor of any findings.
Contract Management System (CMS) means a solution that provides a digital means to record, collect,
transmit and store Contract data.
Determine means the review and establishment of a recommendation and decision by the Contract
Administrator. Often these will be determined in consultation with the MTO CSA and Quality Assurance
section.
Inspection Activities means actions that need to be performed during the work to monitor the contractor’s
compliance with the contract. These activities usually require attendance at the work site to be completed
(e.g., material placement, material sampling for testing, gathering field measurements for verifying
compliance, etc.).
Levels of Inspection (LOI) means the inspection on a percentage “...%” of the item/work being performed for
each inspection activity. Only CAIS inspection activities will include a level of inspection. The LOI for each
inspection activity is denoted by the percentage (%) amount shown in the far right column of the
administrative and inspection activities tables in the CAIS.
Milestones means activities related to the Contractor’s operation that need to be controlled, as outlined in the
applicable specifications and/or special provisions. These milestone activities can be for both administrative
and inspection activities. Milestones are denoted by an “M” in the second column of the administrative and
inspection activities tables in the CAIS. The recording of milestone inspection activities in CA or inspection
diaries is mandatory.
Review means the formal examination of a submission to make recommend changes when appropriate and
includes the use of critical assessment by the Contract Administrator. This is applicable for any Contractor
submissions to the Contract Administrator as specified in the Contract Documents (even if there is no
inspection or administrative activity in the applicable CAIS).
For the purpose of the CAIS, the following specialist acronyms shall apply:
Acronym Specialist
WS Welding Specialist
NDTS Non-Destructive Testing Specialist
FES Foundations Engineer Specialist
ES Environmental Specialist
SCS Steel Coating Specialist
PCS Paint Coating Specialist
SSI Senior Structural Inspector
EI Electrical Inspector
SES Structural Engineer Specialist
The qualifications for all specialty staff will be included in the Contract Administration contract outside of the
CAIS. Where there is a standard CAIS specialist, specialty plans will no longer be required.
As more requirements for specialist services, impacting Contract Administration are standardized, the list of
specialist acronyms and references and the appropriate CAIS will continue to evolve.
These specialist acronyms are referenced, when applicable in the CAIS. These can apply to both
administrative and inspection activities.
For the purpose of the CAIS, the FES and SES shall refer to services delivered by the designer as part of
construction liaison or a design-build team. Where, the FES and SES are only included in the CAIS for
references purposes at this point. The requirements in the designer’s contract shall prevail.
a) All references to “OPSS” shall be deemed to refer to the OPSS (Common or Provincial) specification of
the number and date specified in the applicable CAIS.
b) When the parent specifications and/or special provisions reference other specifications and/or special
provisions within its clause, the CAIS will also refer to the respective CAIS.
The required levels of inspection are specified as minimums. If the Contractor is not performing well, or test
results are continually poor, then the level of inspection may need to be increased to a higher level in order to
check that the Contractor meets the Contract requirements. This situation must be reported to the Contract
Services Administrator. In conjunction with the inspection activities outlined in the CAIS, the Contract
Administrator shall provide qualified personnel to inspect all Work (including all non-civil related activities such
as electrical) as required to verify and document non-compliance to the Contract and the Contractor’s Quality
Control Performance Measures.
Users of CAIS should always refer to the parent specifications and special provisions. For example,
CAIS 206 should be read with the parent OPSS 206 and the associated Special Provisions amending
OPSS 206.
When reading CAIS clauses, users will notice references to “as specified”, or in accordance with Clause
“xyz.01.03”. This aligns with the use of words defined under “Definitions” such as “Check”. This was
developed to avoid unnecessary duplications in the CAIS and the parent specifications and special
provisions.
About Fill-ins:
CAIS include requirements for typical Contract Administration contract. When necessary, the standard CAIS
contain asterisks (*) to denote the insertion of project specific information, similar to Standard Special
Provisions. Standard CAIS may be modified and additional/new project specific CAIS may be developed
when necessary, to address project specific requirements that impact the Contract Administrator’s duties. At
this time fill-ins are only shown in the CAIS for the training purposes.
Project Management is an important duty of the Contract Administrator’s role and responsibilities. The
Project Management responsibilities include the execution of services and deliverables as required in the
Construction Administration and Inspection Specifications (CAIS), forming the Contract Administration
contract.
The scope of Section CAGC 2.0 – Project Management, is captured in CAGC Table 2.0 below. The terms
“Pre”, “During”, and “Post” refers to “pre-construction”, “during construction” and “post construction”
respectively.
As part of its project management responsibilities, the Contract Administrator shall have complete control of
the services, deliverables, staff, and activities it directs and supervises to ensure conformity with the Contract
Administration contract. This includes ensuring that all Contract Administration staff are provided in the
appropriate numbers and with the knowledge and experience to meet the requirements of the Contract
Administration contract.
The Contract Administrator shall contact the MTO Area Manager, Construction and the Contract Services
Administrator (CSA), upon notification by MTO that the Contract Administration Contract is executed. The
MTO CSA will provide the Contract award and execution documents, including the Contractor’s bid prices and
initial critical path schedule.

In order to effectively develop, advertise, and award a Design-Build contract, there needs to be a
well-developed Project Management Structure.
Individual project team members will be required to be engaged in most aspects of project delivery (the RFP
preparation, procurement of the Design-Builder and contract administration/oversight (design and
construction)). As the MTO gains experience with the Design-Build model, the number of members may be
reduced. However, in the interim, representation by all functional offices involved in a project, as is typically
done in traditional project delivery, is recommended. It is also recommended that project team members be
individually selected based on their ability and desire to implement a new model for contract delivery and
oversight.
For continuity purposes, it is imperative to maintain the same project team members throughout the life of the
project.
Although some project team members may only be required on a part-time basis, it is imperative for the
success of the project that the primary project lead has the necessary commitment from the Project Team
members to contribute fully when required, and the authority to utilize their services effectively.
Specific roles and responsibilities for the primary project lead, associate project lead and project team
members may change through the life of the project. The different phases of a Design-Build project along
with the roles and responsibilities of each member are described in the CAIS document titled “Design-Build
Project Management Structure”.
The scope of Section CAGC 3.0 – Communications Management, is captured in CAGC Table 3.0 below. The
terms “Pre”, “During”, and “Post” refers to “pre-construction”, “during construction” and “post construction”
respectively.
Turnover of Documents refers to the documents provided to the Contract Administrator (CA) by MTO’s
Contract Services Administrator (CSA) and includes documents uploaded in the Contract Management
System.
The Contract Administrator shall follow-up with MTO if these documents have not been shared to the Contract
Administrator or uploaded in the Contract Management System:
Before construction begins, the Contract Administrator shall notify the property owners and businesses within
the limits of the Contract as required in the Contract Documents. If the Contract Documents require the
Contractor to complete these notifications, the Contract Administrator shall verify that the Contract Document
requirements are met.
The public, within the limits of the Contract, can be notified by the following methods:
The Contract Administrator shall keep all provide advance notification to all external stakeholder agencies,
that are impacted by any construction activity related to the Contract and keep them informed as required.
These external stakeholders can include: Schools; Fire Authorities; Emergency first responders; Ambulance
services; Transit authorities; Maintenance patrols/operations; Ontario provincial ministries (such as the
Ministry of Environment, Conservation and Parks, Ministry of Natural Resources and Forestry, Ontario
Provincial Police); Conservation Authority(s); Utility companies; Fisheries and Oceans Canada; Railway
authorities; Pipeline companies; Municipalities; Municipal/Regional police forces; and/or Indigenous people.
When the Contractor is working on the highway, the Designated Construction Zone (DCZ) will be handed over
to the Contractor for maintenance and emergency responsibilities, as defined in OPSS 100, subsection
GC 7.08, Maintaining Roadways and Detours. The highway maintenance transfer agreement documents the
date and time of transfer between the Area Maintenance Contractor (AMC) and the Contractor. This process
is used to separate Constructors as defined by the Occupational Health and Safety Act (OHSA).
a) Review the DCZ limits on site prior to highway transfer and document all deficiencies that the Contractor
will not be responsible for maintaining / repairing.
b) Liaise with the AMC and MTO Maintenance about the construction zone limits, the highway transfer date
and deficiencies observed on site, and ask the AMC to review.
c) Prepare and sign the HMTA with the Contractor and obtain signatures from the AMC and MTO
Maintenance to acknowledge.

e) Verify that the Contractor installs the construction zone signs on site on the day of the transfer to indicate
the limits of the construction zone.
f) Submit the Road Report to MTO Traffic Operations Centre using the form provided by MTO.
Prior to transfer back to the MTO agents / the AMC, the Contract Administrator shall:
a) Review the DCZ limits on site prior to highway transfer and document all deficiencies that the AMC will
not be responsible for maintaining / repairing.
b) Liaise with the Area Maintenance Contractor (AMC) and MTO Maintenance about the highway transfer
date and deficiencies observed on site and ask the AMC to review.
c) Prepare and sign the HMTA with the Contractor and obtain signatures from the AMC and MTO
Maintenance to acknowledge.
d) Distribute the HMTA form as indicated on the form prior to the effective date of transfer.

The main difference in measurement for payment for Design-Build Contracts is that the items have been
reduced to a maximum of 14 items which are all lump sum payment (see the “Itemized Bid Form”). This is
reflected in the Design-Build Progress Payment Certificate. Payment for each lump sum item monthly is
based on the percentage completion of the item. The Design-Builder will submit a monthly invoice showing
the percent complete for each item. The CA verifies the invoice through field observations and estimates
possibly in conjunction with review of the Design-Builder’s schedule.
In addition to the payment process outlined in Subsection CAGC 5.02, Contractor’s Payment Approvals and
the Prompt Payment Manual, the Contract Administrator shall:

CAGC 10.06 Ministry Right to Stop the Work - Pre, During and Post Construction
The Contract Administrator is informed that MTO can stop the work if a situation poses an immediate danger
to worker of public safety is observed and not immediately addressed by the Contract Administrator.
Ontario Regulation 490/09 lists the following eleven Designated Substances: Acrylonitrile, Arsenic, Asbestos,
Benzene, Coke Oven emissions, Ethylene Oxide, Isocyanates, Lead, Mercury, Silica, Vinyl Chloride.
Exposure to Designated Substances may occur as a result of activities by the Contractor such as sweeping,
grinding, crushing, drilling, blasting, cutting, and abrasive blasting.
Of the above listed Designated Substances, MTO is aware that Silica, Lead, Asbestos and Arsenic were
widely used in highway and bridge construction in the past and may be present within the project limits. In
addition, there is a possibility that Benzene may be present in certain coating materials (such as coal tar
epoxy) or as a result from a spill or from contamination from an adjacent property.
The remaining Designated Substances are not likely to be encountered in typical construction or maintenance
activities of MTO infrastructure. Acrylonitrile and Vinyl Chloride are in Acrylonitrile Butadiene Styrene (ABS)
and Polyvinyl Chloride (PVC) materials but are not considered Designated Substances once they have been
polymerized and therefore do not need to be identified.
In accordance with the Occupational Health and Safety Act, R.S.O. 1990, c. 0.1, the Contract Administrator is
advised of the presence of the Designated Substances specified in the table below, to which the Contract
Administrator may be exposed when working at the specified locations or while the specified work activities

Inspection Activities:
Check that each scale used for weighed items is within the specified
1 - 100%
tolerances by turning trucks over that scale.
Perform a scale sensitivity and a scale performance test each time a scale
2 - 100%
test is performed.
Determine the scale performance test as follows:
• A loaded vehicle is driven on to the scale deck and the load is balanced out
using the various poise and the indicated weight is noted. Indicated load
refers to the weight of the vehicle used in conducting the performance test,
when weighed at the centre of the platform in the normal direction for
weighing a loaded vehicle.
• Prior to the loaded vehicle driving onto the scale platform, carry out the
sensitivity under zero (0) load and Record it on the “Record of Scale and
Weighing Inspection” submission.
• The loaded vehicle is then driven onto the scale platform until the rear
wheels are just over the end levers, and the indicated gross weight is
captured under the heading “Performance Test”.
• The loaded vehicle is then brought forward to the centre of the scale
platform. The sensitivity test for a loaded vehicle is then carried out and
Recorded on the “Scale and Weighing Inspection” form.
• With the loaded vehicle still on the centre of the scale platform, the weigh
ticket is then made out.
3 - • Enter: the Date, Truck Number, Net Weight and Weight Ticket Number on 100%
the “Scale and Weighing Inspection submission”.
• The loaded truck is then reversed by the person performing the Sensitivity
and Performance tests and Record the net weight in the “Checked Weight”
section.
• Compared with the net weight shown “Net Weight shown by the weigher”
section.
• Obtain the Gross Weight and enter it under “Performance Test”. This gross
vehicle weight is the “Indicated Load” when calculating the “Limit of Error”.
• Drive the loaded vehicle forward to the end of the platform scale so that the
front wheels are just over the end levers.
• Obtain the gross vehicle weigh.
• Drive the loaded vehicle off the scales, turned around and weighed in the
reverse order.
• Issue the weigh ticket to the driver.
• Sign the scale Sensitivity and Performance submission and add any
remarks regarding the test results.
