Ongoing work - 81 Bay Overbuild


Work crews associated with the Hines CIBC 81 Bay Overbuild construction project are presently installing steel beams and columns to support the new pavilion that will eventually house several new restaurants within this new complex. The work is performed overnight, and although every attempt is taken to address levels of noise, work will be disturbing to some. Please note this work will continue for at least another 3 1/2 weeks, into November.

Looks like they need room for the supports for the electrical conduits over Yonge Street and a walkway too.

Does anyone know what all the electrical prep work is for? Back up power, an alternate source/switch gear for Union or future train electrification, or maybe track switching control?

^The yellow utility markings in that aerial shot indicates gas lines for the switch heaters. All that conduit work is for the new signalling system. That implies both electrical supply for switch motors and signal lights, and wiring for track circuitry, the red markings.
There are new concrete pads for signals infrastructure, and new signals bungalows, going in all over. I expect it’s all electrification friendly, but not a sign that electrification itself is being advanced.

19-137 - RFQ to Form an Alliance for the GO Expansion Union Station Enhancement Project

DESCRIPTION
GO EXPANSION UNION STATION ENHANCEMENT PROJECT (“USEP” or the “Project”)

Description of Project:

The purpose of the Project is to design and construct infrastructure upgrades required at Union Station, located in the City of Toronto, to accommodate the planned expansion of GO Transit rail services. This early works phase is required in advance of the larger GO Expansion Project (OnCorr) in order to facilitate future track closures for the reconstruction of platforms within the existing train shed, and to reduce the overall impact to the OnCorr construction schedule.

The USEP provides two wide platforms and a new concourse south of the existing trainshed. The new passenger concourse will span from Bay Street to York Street and connect into the existing Bay, VIA and York concourses to the north. The Project will reconstruct platforms 24/25 and 26/27, increasing the width and re-aligning track to permit higher speeds and allow for greater train and pedestrian throughput. The general scope includes the new concourse and associated platforms, canopies, vertical access, electrical and mechanical works, track and signal works, storm water management system and provisions for future modification for level boarding.

Here's your answer!

Surprised it hasn't been posted but, GO/Metrolinx has tendered out the South Concourse rebuild with MUCH wider platforms, better vertical access and provision for level platforms (plus it looks like it will be electrified first). The tender can be found on Need though a render is also now at the bottom of the Union Station Construction Page on GOs website. I've inserted it below.


Video to come.

The problem is, that the same RFQ went out in 2017, and the RFP went out in 2018:

Now they're starting all over again. No rush!

Depressing actually, it implies to me the main tender is behind schedule.

This piece was (publicly) pulled into the main tender just last spring at the same time as the Union East/West pieces.

^ Interesting. Wonder why? Budget change?
These things happen for several reasons:

The project has changed in some significant way. (Making it larger or smaller)
There were either NO responses to the first ads or they were all over budget.
A project has turned into two projects and 'they' want to have different consultants or see if they can get a better price.
The earlier call stated dates that are no longer relevant and they need to re-advertise with new dates.

Any reason why they don't use electrical heaters instead of gas? It sounds like an odd choice given the increased complexity and possible gas hazard.
