New Building System used in Sugarcreek Village

The Sugarcreek village project currently under construction on London, Ontario utilizes a new building system that enables a combination of long spans and slim floor structure. Through the use of the Deltabeam system, Oldoak properties was able to optimize the design of the underground parking and reduce the overall height of the project.  Sugarcreek village consists of two buildings, each 5 storeys high, connected together by an underground parking.

Designed by SRM architects inc. and MTE consultants inc., this new apartment building incorporates Deltabeam combined with the Comslab corrugated deck system. Deltabeam is a shallow steel beam designed for slim floor structure: encased in the concrete floor, deltabeam is hidden in the floor structure (see image below). This enables easy HVAC integration, increased architecture flexibility and can reduce the overall height of a building. On the residential levels of Sugarcreek Village, Deltabeam spans across the equivalent of the driving aisle, making it possible to avoid all load transfers at ground level.

‘’With the Deltabeam System, we were able to avoid costly transfer beams at the ground level of Sugarcreek Village’’ says Ryan Peel, Manager of Development and Construction at old oak properties. ‘’With the exposed steel integrated fire rating of Deltabeam, we are avoiding having to fire proof the exposed steel and therefore avoiding another trade onsite’’. Old Oak Properties is a developer and builder of premium residential, commercial and retail properties in London, Ontario since 1955.

Low Head-Room Issues?

I can't think of a better way of explaining one of the benefits of Deltabeam than by comparing the two following pictures.

The picture on top was taken in a cast-in-place parking garage in downtown Winnipeg. You can clearly see the "Caution, low head-room" sign on the beams projecting under the slab.  

The picture on the bottom was taken in a the Holiday Inn in Saskatoon completed in 2010. It's actually hard to see the Deltabeam on the picture (which is probably a good thing) but they are spanning over the drive aisle. 

Which one looks easier to coordinate for minimum clearance requirements?

High Rise Condominiums with the Tricar Group

When we visit a Tricar job site, It's always a unique experience. We have done 4 slim floor high rise projects with this London based builder. In Guelph, we did a 18 story condo building in 2013 and are now involved in a similar project just a few blocs away (see picture).

The second phase of the Guelph River Mill project was designed with a Deltabeam slim floor for a number of reasons:
- Fit as many floors as possible in a given building height
- Enable flexible layout of the condo units
- Lose fewer construction days to bad weather

" We lost 6 days due to poor weather conditions on phase 1 of river mill. With traditional poured in place construction, that would have been closer to 40 days" says Joe Moir, site superintendent for the river mill projects.

For the Deltabeams specifically, the integrated fire rating is a big plus: "Beyond avoiding another trade on site and speeding up the construction process, fire rated beams reduce the heating cost of the project overall". In fact, Deltabeam requires no additional application of fire resistant material: it is the first fire rated exposed steel beam in Canada. With traditional steel beams, the application of intumescent paint was required, during which a minimum temperature of 10* C is needed. "The heating costs involved in applying such material during winter are considerable, and winter application is impossible to avoid" states Mr. Moir.

CLSC des Faubourgs - Montreal

As the first post on this blog, I would like to share a picture that was taken 2 weeks ago on a job site in Montreal. This project uses a combination of steel structure and hollow core slabs. Through the use of Deltabeam (the gray beam in the picture), the builder was able to locally reduce the floor thickness to 200 mm + topping: the same thickness as the hollow core slab.
On the upper levels of this building, the slim floor was needed specifically for mechanical systems integration. At the parking level, Deltabeam was used throughout the floor structure to increase clearance and reduce the use of fire resistant material.

High Rise Deltabeam Project with The Tricar Group

Reaching a whopping 30 storeys, the Renaissance II condominium building in London, Ontario is among the tallest precast buildings in North-America. Using Deltabeams throughout its 26 residential floors, the skyscraper has become a beacon of performance and reliability for the Deltabeam solution.

Renaissance  ii  is  a  high-end  condominium project with 156 condo units,  each  overlooking  beautiful sights of “Forest City”. Developed and built  by the Tricar Group, the behemoth is seen as part of the precast revolution currently taking place in southwestern Ontario as an increasing  number  of  developers  choose to  build  with  faster  and  more  economical building material. Tricar is now working on a third project using the Deltabeam solution in Guelph, Ontario.
Innovators at HGS Ltd.
internationally renowned  hGs ltd. were chosen for the structural design of the building. Medhat Ghabrial, Vice President of Ontario’s most prominent precast structural engineering firm, supported the Deltabeam solution which enabled a uniform floor thickness of 10-3/8’’ (26.4 cm). Dr. Ghabrial understood the reduction of floor depth and worked hand in hand with Peikko on the high magnitude project. The project as a whole consists of two twin 30 storey towers with a parking tower in-between. The first skyscraper was done in 2003 with a cast-in-place frame and patented flooring system. Though there was no major problem using this system, it was labor extensive and created a low quality slab, not to mention the average floor thickness which toped a total 18 inches (46 cm) per floor. The second skyscraper is being finished summer 2012, using Deltabeam and hollow core on most levels. This incredible solution creates a uniform 10-3/8’’ (26.4 cm) thick flat slab, enabling a 19 feet (5.5 m) increase of floor to ceiling space on a total of 26 floors. Further comparing both towers, numbers speak for themselves:

An Added Value Solution
The  Tricar  Group’s  Chris  Leigh  saw  the potential of using the Deltabeam combined with hollow core slabs, especially to avoid any headroom issues and increase of floor to ceiling height by 2 feet (60 cm) over a total of  5  storeys.  “We  had  a  precast  concrete solution  that  would  greatly  increase  our speed  of  construction  and  reduce  our workforce onsite, but we needed a thinner total floor thickness” says leigh. “Keeping the  same  floor  depth  while  having  a  22  foot (6.7 m) opening of unobstructed space initially seemed impossible”. That’s exactly what the Deltabeam made possible: six wide and clear openings per floor, giving upcoming residents  huge  flexibility  to  arrange  their condos. This  project  is  a  good  example  of increased  rOi  thanks  to  the Deltabeam, as Tricar was able  to sell several floors  of high-end  condominiums  at  a  higher  price thanks to their tall ceilings (11 feet, 3.4 m).  Olimpio  Couto,  Precast  Manager  for  the renaissance  ii,  says  working  with  Peikko was  a  charm.  “Peikko  always  supplied  the Deltabeams ahead of time. The beams were easy  to  install  onto  our  parallel  concrete walls  and  involved  very  little  shoring compared  to  your  typical  cast-in-place structure.’’ explains Couto. ‘’The shore free space was especially good for other trades to come in early during the project, trades such  as  electricians,  plumbers  etc.’’  The Tricar Group is based out of london, ON, and specializes  in  the  development  of  luxury condominiums for sale and apartments for rent  in  southwestern  Ontario. Tricar acts both as a property development and property management company.

Key Partners in the Project
The  precaster  chosen  for  the  renaissance ii  is  stubbe’s  Precast.  Throughout  the project,  they  were  recognized  for  their professionalism and expertise with hollow-core slabs, only equal to their impeccable support  during  project  installation  and beyond. located in a small town less than an hour away from london, stubbes supplied a turnkey solution including other precast elements such as precast cladding.

Deltabeam Gains Pupularity in Canada
The  Deltabeam  solution  is  becoming increasingly popular in Canada. The Tricar Group  alone  is  working  on  yet  another  multi-storey  project  using  Deltabeams,  which will total three Deltabeam  projects for the real estate company in less than two years: renaissance ii, renaissance Parkade and  riverhouse  Condominiums.  Further more,  two  major  multi-storey  projects  are  well  on  their  way  in  Winnipeg,  Manitoba: Grand  Airport  hotel  and  Centerpoint residential-hotel-commercial-parkade project. Finally, several residential projects are  also  moving  forward  throughout  the Quebec  province:  le  Mesnil  and  Quartier urbain 395.
