Study Notes

Ontario Traffic Manual (OTM)

The Ontario Traffic Manual (OTM) provides best practices for traffic control on Ontario highways and streets.
OTM aims to ensure safety for workers and road users.
OTM complies with the Occupational Health and Safety Act (OHSA) safety requirements.

Temporary Conditions

Temporary Conditions are work areas within the right of way.
Off Shoulder work is outside the shoulder, not encroaching on it.
Shoulder work is on the shoulder, not encroaching on traffic lanes.
Lane Encroachment is partially within the travelled lane, maintaining at least 3.0m (3.5m for freeways) of free lane width.
Partial Lane Shift realigns a lane when roadside work reduces lane width below 3.0m, diverting traffic to another lane.
Lane Closure completely shuts down one or more travel lanes, redirecting traffic within the existing roadway.
Detour routes traffic away from its usual path when the road cannot accommodate it.

Traffic Control Persons (TCP)

TCPs require a CSA-certified hard hat with reflective tape for night work.
TCPs must wear CSA-certified safety boots.
Eye protection, including clear safety glasses for night or overcast, tinted safety glasses for sunny days, and goggles for extreme dust and wind, are required.
A TC-22 traffic control sign for hand signaling is essential.
A two-way communication device is recommended.
Night-time TCPs require a well-lit station, a flashlight with spare batteries, and a mandatory two-way communication device.

Traffic Control Devices (TCD)

TCD includes signs, barricades, cones, drums, flashing lights, and other devices for safety.

Paid Duty Police Officers

Paid Duty Police Officers are required to control traffic within intersections with active signals.
The use of Paid Duty Police Officers in other work areas is optional.
Paid Duty Police Officers must comply with MOL requirements for PPE.

Site Mobilization

Site Mobilization involves setting up facilities for construction operations.

Site Mobilization Plan

The Site Mobilization Plan includes:
- Project specific details, including budget and schedule.
- Layouts for the field office and site plan.
- Location of parking, refueling, and maintenance areas for equipment.
- Storage areas for materials and equipment.
- Construction equipment needed.
- Site signage with health and safety information.
- Evacuation areas and emergency route plan.

Service Locates

Service locates identify underground utility services before any excavation.
Locates are markings on the ground (stakes, flags, or paint) by the utility owners.
Utilities include:
- Water Mains
- Hydro
- Gas Lines
- Bell/Rogers
- Storm
- Sanitary

Ontario One Call

The Ontario One Call (1-800-400-2255) system coordinates utility locates.
The contractor calls One Call to request locates.
One Call contacts utility owners for marking.
Storm and sanitary utilities may require separate contact.
The locates process can take 3-4 weeks.
Locates have an expiry date.
Locates only confirm the existence and alignment of services, not their depth.

Site Boundary and Fence

The site superintendent identifies site boundary monuments from the topographic survey.
Monuments can be various shapes and materials.
Topographic survey also provides quadrantal bearings for boundary confirmation.
Site fences:
- Are required by law (City Bylaws, OHSA).
- Prevent public access for safety.
- Deter theft from construction sites.
- Protect adjacent properties from damage.

Control Points

Control points for elevations and bearing references must be protected from damage.
Concrete monuments help prevent settlement or shifting.
Control points should be verified by the surveyor regularly.

Field Office

The site superintendent sets up a field office, or "job shack," for management.
The location of the field office should consider:
- Proximity to site entrance.
- Existing hydro and communication services.
- Ease of access for visitors.
- Proximity to the workplace.
- Trade foreman access.
- Ease of monitoring work, deliveries, and materials.

Temporary Hydro Connection

An application must be submitted to the local hydro company for temporary power.
The hydro company representative visits the site with the applicant to determine the best location for the temporary connection, usually near the site office.
The hydro company provides an invoice and layout drawing for the connection.
