You can wash your hands 100 times, scrub the floors until they shine, and disinfect every piece of equipment after each use - but in a hospital, the air itself can pose the greatest risk to a severely ill patient.

 

The smallest airborne virus can wreak havoc, so the ventilation, air filtration, thermostats and humidity control systems must be able to filter these bugs out and keep contagious patients isolated.

 

The new mega-facility going up on the Glen campus will be light years ahead of Montreal's existing hospitals in terms of environmental control, said Antonin Bouchard, the McGill University Health Centre's associate director of engineering and operations for the Glen.

 

"In the buildings we have now . many patient rooms are not environmentally controlled at all, so you can open the windows and be subject to the external environment," Bouchard said.

 

"Really, there is going to be an enormous improvement" in the new buildings.

 

For patients whose immune systems are compromised, the Glen will have some rooms that are positively pressurized - meaning virtually no exterior contaminants can seep in. Other rooms, housing patients who are potentially contagious, will be negatively pressurized to protect the rest of the hospital population from infection.

 

Some areas, like operating theatres, will have much higher rates of air circulation than other rooms, and high-efficiency particle absorption systems will filter out 99.99 per cent of foreign particles throughout much of the campus.

 

All of the ventilation systems will be regulated through a computerized "building management system" and can be monitored around the clock. If something goes wrong or equipment fails, alarms will alert technicians, Bouchard said.

 

The same system will control temperature and humidity throughout the hospital, depending on needs linked to treatment, patient comfort and even equipment.

 

"When you're doing complex, ultra-specialized surgeries ... it becomes very important to be able to control the temperature and humidity for certain procedures," Bouchard said.

 

"In the same way, with highly specialized bio-medical equipment like oncology equipment or CT scanners, we need to maintain a specific environment."

 

The environment will be modifiable, especially in areas where equipment may change over time. New equipment can often withstand a wider variety of environmental conditions, Bouchard said.

 

The planning for these systems has been going on for years, he added, and the MUHC had to ensure it met international standards and various best practice models.

 

All of the environmental equipment will be installed during the hospital's construction, so it was crucial that the construction consortium be kept informed of the possible needs in each block of the campus, Bouchard said.

The McGill University Health Centre has started the tendering process for some of the biggest pieces of equipment to be installed on the Glen Campus. Over the next several months, companies will submit proposals to supply everything from linear accelerators to refrigerators for the new mega-hospital, to open in the fall of 2014.

 

"There are quite a few tenders already out there," said Imma Franco, associate director of programs and services planning for the MUHC.

 

"(The tendering process) allows the MUHC to select the preferred vendor in advance in order to give the construction consortium the shop drawings for a specific piece of equipment."

 

Those shop drawings are crucial for construction bosses to have in hand as the hospital takes shape.

 

Some machines will require reinforced slabs to support their weight. Others, like the equipment used in radiotherapy, will require shield walls to protect staff and patients.

 

Still others will have specific needs in terms of ventilation or temperature, Franco said.

 

"There's a whole team of project managers, engineers and planners who are writing all of the specification for these large pieces," Franco said.

 

"It's partially my planning department (that is organizing the integration of large equipment), but in co-ordination with the biomedical, mechanical and electrical engineers at the MUHC."

 

Many of the big pieces of equipment - such as sterilization machines, kitchen equipment and ventilation hoods in the labs - will be integrated during the construction process, but others will be moved in at the last second. Much of the biomedical equipment, for example, won't arrive until shortly before the Glen opens.

 

"One of our biggest fears is to open a hospital with outdated equipment," Franco said.

 

To avoid that, the MUHC will have the option to make changes to their equipment contracts as technology evolves over the next three years. The specifications for a linear accelerator ordered today could change significantly by the time the fall of 2014 rolls around.

 

"That's incorporated in the bid documents," Franco said. "The vendors know what's coming in the next five years, and they'll have to submit their proposals accordingly."

From the Gazette this morning:

A 10th crane will be added in August, and four more tower cranes will be installed over the coming year to help with the construction of the Glen's two parking garages. That will bring the total number of cranes on the site to 14, the most ever on a single project in Quebec.
