1.0 INTRODUCTION The purpose of this report is to outline the Construction Management Plan and Resident

Communication Strategy that will be in place with respect to the development of 33 Yorkville. The

subject land is situated between 27-37 Yorkville Avenue and 26-32, 50 Cumberland Street. The outline

of 33 Yorkville has been shown in red.

Figure 1: 33 Yorkville Site Boundaries.

This report outlines the measures that will be taken before and during construction of the site.

2.0 Resident Communication Strategy • Once concrete and formwork begin, up to date (weekly) construction schedule and milestone

posts will be uploaded onto the construction communication website

https://33yorkvilleconstruction.com/

• Community Information Boards will be posted on site and will contain contact information for

site staff during business hours, contact numbers for 24 hour response, Cresford head office

contact details and the 33 Yorkville construction communication website.

3.0 Hoarding, Fencing & Emergency Access The construction site will be hoarded/ fenced as illustrated in Appendix 1 of this report during the

construction of the project from shoring and excavation to topping off. The anticipated timeframes for

these periods are provided in Appendix 2 – Project Timelines. A typical detail of this hoarding/ fencing

will be provided in Appendix 3 and will be updated accordingly. All gates will be locked during hours

where no construction activity is occurring.

3.1 Fire and Emergency Access

• Emergency vehicles will access the site through the construction gates which

remain open during construction hours. After-hours access will be granted by

on site security or as typical Toronto Fire will cut the chains and open the

fencing.

• Temporary fire standpipes will be installed based on the appropriate stage of

construction. Fire extinguishers will be located on each floor, throughout the

construction site.

4.0 Traffic Management

4.1 Traffic Management Plan

• BA Group has prepared a traffic management plan which shows the

gate locations for construction traffic into and out of the project

location.

4.2 Police Call-Duty

5

• Call-duty officers will be requested to control traffic when required;

Examples of when call-duty officers may be required;

o Building crane erection and dismantle

o Large deliveries of equipment which may impede traffic flow

o When work over or on Yorkville Avenue or Cumberland Street

is required

4.3 Flagperson

• Qualified flag personnel will be employed throughout construction to

assist with the flow of construction vehicles entering or leaving the

site. No vehicles will be permitted to back up onto Yorkville Avenue

or Cumberland Street without flagman assistance.

5.0 Crane Locations The location of the cranes required for the project will be communicated once the crane locations have

been determined.

6.0 Piling & Shoring Piling and shoring works will be installed in accordance with the piling and shoring/ encroachment

agreement and permit issued by the City’s Transportation Services (Right of Way Management) Division.

The tieback locations and piles are designed to avoid conflicts with municipal services and utilities.

7.0 Vibration A Zone of Influence Report has been completed by Cresford Developments Engineers (Petra Consulting

Engineers) and illustrated in the Vibration Assessment Report, dated September 2017. All precondition

reports recommended in that report have been carried out. Vibration monitoring equipment as

recommended in that report will also be in place and actively monitored.

8.0 Working Hours/ Noise Logistics of Concrete Pours:

In relation to any concrete pour, after the trucks that have delivered the concrete leave, the construction crews must finish the freshly poured slab. This is consistent with standard construction practice. This process involves the concrete finishers waiting until the concrete hardens enough (1-3 hours sometimes more, depending on ambient temperature) to allow the finishing machines on top of

6

the slab to provide a smooth level concrete surface. If this is not done the concrete will harden creating a deficient structural component, jeopardizing the integrity of the tower construction.

Timing of Concrete Pours:

Prior to any concrete pour, the required forming and rebar work must be completed. This frequently takes several hours. As well, the timing of concrete pours is dependent on the concrete suppliers availability to deliver concrete to the Site. In a large pour, for example for a floor slab, even if it is possible to begin in the morning, the work may still stretch into the evening, given the amount of concrete and the time it takes to pour and finish it.

Every effort is made to complete the work within the prescribed times set out in the City of Toronto’s construction noise by-law. No concrete pouring is permitted on Sundays or Statuary holidays.

Please note that the City of Toronto’s construction noise by-law permits continuous concrete pours to continue past 7:00 pm when construction logistics require this.

The noise by-law stipulates the following permission:

TORONTO MUNICIPAL CODE NOISE § 591-2.1 [Excerpt] Construction. [Added 2007-12-13 by By-law No. 1400-2007] (1) No person shall emit or cause or permit the emission of sound resulting from any operation of construction equipment or any construction, if it is clearly audible at a point of reception: (a) In a quiet zone or residential area within the prohibited period of 7:00 p.m. one day to 7:00 a.m. the next day, 9:00 a.m. on Saturdays, and all day Sunday and statutory holidays; or (b) In any other area within the prohibited period of all day Sunday and statutory holidays. (2) Subsection B(1) does not apply to the continuous pouring of concrete, large crane work, necessary municipal work and emergency work that cannot be performed during regular business hours.

9.0 Truck Access There are 2 access points on Yorkville Avenue and 3 access points on Cumberland Street during

construction, as illustrated in Appendix 1b. All trades will be provided with a copy of this plan and a

qualified flagman will be present during entrance and exit to ensure that there are no conflicts with the

vehicles and pedestrians.

10.0 Site Servicing/ Utilities

If any of the utilities or services will be temporarily affected or interrupted, notice will be provided as follows: (I) to

the tenants through the property manager of a specific building; (II) posted on the construction communication

website https://33yorkvilleconstruction.com/or (III) delivered directly to the property owner. Special efforts will be

taken to ensure minimum disturbance to tenants and property owners.

11.0 Dust Control & Site Cleaning Dust will be controlled on the Site using a variety of techniques based on varying site and

weather conditions. Techniques to be used for dust mitigation on the Site include (but are not

limited to) the placement of mud mats at all truck access points, the spraying of water on

vehicles and wheels when leaving the site, the spraying of calcite along the access routes to

maintain moisture and to minimize dust kick-upon construction roads and regular street

sweeping and watering to clean paved surfaces (details for mud mats have been attached as

Appendix 4. Effectiveness of dust control is dependent on the frequency of use/ application

which will increase during periods of dry weather.

Site sidewalk and pedestrian paths along Yorkville Avenue and Cumberland Street will be

cleaned and swept daily. When required, the sidewalk and paths adjacent to the Site on

Yorkville Avenue and Cumberland Street will also be cleared of snow within 12 hours of snow

accumulation.

11.1 Stormwater Management, Erosion and Sediment Control During Construction

• Stormwater management during construction will take place as per the

recommendations provided by Cresford’s consultant Odan Detech Consulting Engineers.

• Surface runoff from the Site will pass through sedimentation filter cloth affixed to the

hoarding at the perimeter of the Site and then through a second filter cloth attached to

each catch basin. Details are provided in Appendix 5.

12.0 Anticipated Project Timelines The project anticipated timelines are provided in Appendix 3. Resident Communication Strategy weekly

updates will be uploaded onto the construction communication website

Appendix 2: Project Timelines

Activity Forecasted Start

Forecasted Completion

Duration Description

Demolition November, 2018

March, 2019

5 Months Remaining

The first part of demolition takes places internally. Demolition contractors remove any potentially harmful substances and deal removing fixtures, appliances and other mechanical equipment. Once interior work is complete, the buildings will be demolished. Most of the removal of the building will take place during excavation. Water is used to minimize dust.

Shoring/Excavation

March, 2019

February, 2020

12 Months The first stage of shoring involves the vertical drilling of piles into the ground. Some concrete will be delivered for the piles, but the truck traffic will be relatively light. Once the piles are complete, removal of the demolished building and soil begins. This stage is truck heavy and dusty. Water is used to minimize excessive spreading of dust.

Form to Ground Floor

February, 2020

November, 2020

10 Months The very bottom level of this building will be a raft slab. This is a long and intensive pour. The crane will be installed and then the forming of the garage will begin. Concrete and steel will be delivered to the site as per the construction staging plan.

Above Ground Forming

December, 2020

February, 2023

26 Months Ahead of above ground forming, overhead protection will be installed where required. Delivery of concrete and steel will be similar to below grade work, but with some degree of regularity. Long pours will be reported on the construction information web site.

Finishing March, 2022

December, 2023

22 Months Smaller delivery trucks will share the staging areas to deliver all finishes to the site.

Occupancies February, 2023

January, 2024

11 Months Occupants will start moving in to the building
