Construction Mangement Plan

Construction Sequence

2.1. STAGE I – DEMOLITION

This stage of construction includes the following activities:

• • Asbestos removal and disposal;
  • Demolition of one, three-storey existing building on Site;
  • Disconnection of all existing utilities and servicing infrastructure entering and contained within the Site; and
  • Removal and trucking of construction debris (asphalt, building material, etc.).

Prior to commencement of any construction activities, the perimeter of the Site will be secured with fast fence, or an equivalent fencing system. The primary activity within this phase is the demolition of the three (3) three-storey mixed-used building on Church Street (250 Church).

Construction vehicular activities are anticipated to be low, with the majority of vehicles being dump trucks. Loading and unloading during this phase will be from within the Site.

2.2. STAGE II – SHORING AND EXCAVATION

This stage of construction includes the following activities:

• • Levelling of the sub-surface after demolition of asphalt
  • Drilling and installation of caissons and piles;
  • Installation of lagging, tieback, rakers and corner supports; and
  • Excavation of the Site

This stage commences with levelling of the Site, followed by drilling and installation of the caisson and piles. The proposed shoring system includes a number of supports within the system such as corner bracing, rakers, and tiebacks. Once in place the caissons and piles act to secure the perimeter of the Site, which enables the commencement of excavation. As the excavation progresses, lagging and additional supports are installed, until excavation comes to completion.
During the shoring and excavation stage, construction vehicular activities are anticipated to be heavy. The type of construction vehicles are predominately dump trucks during excavation and concrete trucks during shoring. Loading and unloading during this phase will be from within the Site.

2.3. STAGE III – BELOW-GRADE CONSTRUCTION

This stage of construction includes the following activities:

• • Completion of detailed excavation for footings and sub-slab drainage;
  • Installation of sub-slab drainage
  • Pouring of footings;
  • Erection of tower crane;
  • Installation of Site servicing connections;
  • Installation of blindside waterproofing;
  • Pouring of foundation walls; and
  • Pouring of concrete slabs

Following the detailed excavation for sub-slab drainage and footings, the drainage system is installed and footings are poured. This stage also includes the erection of the proposed tower crane and installation of the Site servicing connections. Blindside waterproofing is installed on shoring wall prior to the pour of the verticals (foundation walls and columns). The initial slab is poured and the sequence of verticals and slabs continues until the foundation is brought to grade.

During the below-grade construction stage, construction vehicular activities are anticipated to be low. The anticipated type of construction vehicles are predominately concrete trucks. To a lesser extent other construction related vehicles are anticipated, such large flatbed tractor trailer trucks for early morning steel delivery and other delivery vehicles such as single-unit trucks and typical cube-vans.

2.4. STAGE IV – ABOVE-GRADE CONSTRUCTION

This stage of construction includes the following activities:

• • Completion of above-grade structure;
  • Enclosure of building envelope;
  • Installation of roofing;
  • Installation of windows; and
  • Installation of precast masonry.

Above-grade construction commences with the continuation of the concrete structure. Following slab-on- grade verticals are formed and poured and the sequence of slab and verticals continue to the top level of the structure. Building envelope will follow the structure up the building. This stage will conclude with the installation of windows, precast masonry and roofing.

During the above-grade construction stage, construction vehicular activities are anticipated to be low. The anticipated type of construction vehicles are predominately concrete trucks. To a lesser extent other construction related vehicles are anticipated, such large flatbed tractor trailer trucks for early morning steel delivery and other delivery vehicles such as single-unit trucks and typical cube-vans

2.5. STAGE V – COMPLETION OF INTERIOR FINISHES

This stage of construction includes the following activities:

• • Erection of interior stud walls (framing, insulation, drywall)
  • Installation of internal mechanical and electrical systems;
  • Millwork;
  • Installation of flooring; and
  • Painting.

Once the proposed building structure is complete, the remaining stage includes the overall interior finishes. This work ranges from plumbing, drywall, cabinetry and electrical components of the proposed building.

During this construction stage, construction vehicular activities are anticipated to be low. The anticipated type of construction vehicles are predominately delivery vehicles such as single-unit trucks and typical cube-vans.

2.6. STAGE VI – STREETSCAPE/ BOULEVARD WORKS

This stage of construction includes the following activities:

• • Landscaping (on-grade, street boulevards, and podium structures – including terraces and green roofs)
  • Installation of new curbs and sidewalks;
  • Installation of street lighting to the internal project, with landscape structural elements;
  • Re-instatement of street furniture and utilities (if applicable) removed to facilitate construction and
  • Installation of post-construction regulatory and warning traffic signage.

The final stage of construction includes internal Site works such as hard and soft landscaping (on grade, terraces, green roofs, etc.) and the installation of street lighting on the internal Site laneways. Streetscape works on the adjacent surrounding streets includes the installation of new curbs and sidewalks, installation of new street lighting, and hard and soft landscaping of the boulevard. Lastly, as right-of-way occupancies are no longer required, the right-of-ways will be returned to either their pre-construction condition or post- construction condition, if changes have been proposed. This includes the re-instatement of street furniture, utilities (if applicable) and traffic signage.

Construction vehicular activities are anticipated to be low, with the majority of vehicles being dump trucks and small delivery trucks (typical cube-vans).

Construction Management Plan

• • All Ministry of Labour requirements and safety polices will be strictly adhered;
  • Compliance with the Occupational Health and Safety Act;
  • All construction protocols will conform to City of Toronto By-Law requirements with respect to noise control, dust control and construction operation period.
  • Traffic control persons will be utilized when required to direct traffic and cyclist activity;
