Objective:

Guide the client’s project to meet a schedule promoted by the pre-sales of units to ensure future residents can accurately plan for their next steps, working through any unforeseen items which could delay the project schedule. Remain flexible and develop strategies to maintain schedule while adapting to the client’s needs and changes as their needs evolved to their client’s expectations.

Execution:

Careful planning of all resources was necessary as the facility’s location on a quiet residential street meant there was no access to a staging area for deliveries of concrete, precast and structural steel. All deliveries and large volume concrete pours had to be carefully staged so the street remained accessible for the resident’s regular activities, as well as ensuring access to emergency vehicles should the need arise.

The schedule often required the use of multiple mobile cranes on site simultaneously, along with earth moving equipment, adding to the complexity of the staging plans.

Various systems are connected to the existing facility, and the connection of these systems had to be planned carefully to limit the disruption on the existing LTC facility.

CSL proposed a revised foundation design to the team, which, when executed, avoided the costs and risks of temporarily shoring the neighbouring homes at the higher elevation, resulting in reduced expense, accelerated schedule, and the mitigation of the risk to the adjacent properties.

Execution:

Because the lower parking level was below the water table, CSL was not able to use shoring tie-back systems, we required steel rakers be installed inbound of the excavation every fourth pile to support the shoring. To address the challenge of being below the water table, a complex hydrological passive drainage system was designed and implemented beneath the lowest slab levels to manage the constantly flowing water, 1.2 million litres of water each day. 

With the condo being built on an urban infill site and in close proximity of occupied buildings, the shoring and excavation program needed to be completed (a 4-month endeavour) before the tower crane pad could be cast and the foundation work begin.

Many innovative techniques were implemented during the construction for this project. A project specific blindside waterproofing membrane had to be developed  to satisfy the site conditions. Once the waterproofing membrane was installed on the timber lagging, CSL knew that the traditional one-sided forming system for this wall was going to be a challenge. We developed a plan to implement the first two-storey, architecturally finished (exposed) structural shot-crete wall in the K-W Region - a pioneering effort by all to accomplish.

Execution:

During the planning and scheduling process, CSL developed the TIMLOCK ARIAL SCHEDULING SYSTEM (TASS) that shows vertical node activity on various floor levels of the project.  This allowed everyone reviewing the schedule to pinpoint how many tradesmen would be working on any given floor on any day. (TASS won the Innovation Award of Excellence at the Building Excellence Awards.)

As a total precast project, MyREZ required an enormous amount of coordination with the mechanical, electrical, and sprinkler trades. Each piece had its own piece ticket (shop drawing), which needed to be circulated to each of these trades for the precise layout of service penetrations – all of which needed to be completed months before M&E services were installed! There were 156 separate precast wall pieces per floor on 19 floors - or 2,964 separate piece tickets for the project. It took a team of detailers four months to produce all the piece tickets required.

The super structure of the 19 storey building was erected in just 20 weeks. (Two weeks for the ground floor and one week each for the balance of the floors). An amazing accomplishment!
