Mass wood has already proven its climate. What becomes clearer at the accumulation of projects is your advantage in time and work. The speed of the construction and smaller, more specialized crews achieve economic advantages that go beyond carbon accounting. They reduce costs, compression plans and open new markets such as upward extensions in existing buildings in which traditional reinforced concrete is too heavy. These are not side notes, but the basic reasons why developers and cities take note of it.

This is one of the last articles in my series in which the role of mass wood in Canada's living and climate too. The first piece determined Canada's wood moment, which held the CLT and modular construction as the fastest lever for combating housing deficiency, jobs and embodied carbon. The second examined how Mark Carney's housing initiative could industrialize the sector through previously approved designs, offte-section contracts and regional factories. The third examined the requirement for vertical integration in the industry to maximize efficiency. The fourth showed how the CLT shift could bend the demand curves for cement and steel and make its decarbonization paths more realistic. The fifth showed that CLT already closes more carbon from the harvest to the housing than it emits and strengthens its climate cases.

The sixth turned to the forest chain and argued that the electrification of harvesting, transport and processing is of essential importance for maintaining the CLT carbon advantage. The seventh piece dealt with systemic obstacles that focused on high insurance costs and tailor -made permits, and argued that the normalization of the mass wood in regulatory and financial framework is the key to scaling. The eighth piece, which should have been much earlier in the series, examined the various technologies in mass wood and its currently dominant form Crod-Laminated Timber (CLT). The ninth piece evaluated the global managers, opportunities and the competition for the Canadian mass wood industry and the lessons for learning. The tenth piece deals with contributions to workers and financing that I received in the course of the series of experts who are employed in the room. This piece focuses more on a speed and work option that has shown mass wood construction.

The nine -story Murray Grove building in London, which is often referred to as a stadium house, became the first iconic demonstration of this potential. The CLT frame was built by only four carpenters in 27 working days over nine weeks, with a mobile crane and a prefabricated sections used. A comparable concrete frame would have five to six months larger five to six months, together with the tower crane rental and more disturbances in the neighborhood. The message was this time and people could be saved while they still deliver a permanent structure.

Brock Commons in Vancouver presented this message on a larger scale. The 18 -story hybrid wood tower was built with a crew of nine installers who have completed the structure and facade in 66 days. The local contractors estimated a concrete tower of this amount for six to eight months of work with crews of 40 to 60 people at the peak. The wooden tower rose at a pace of two floors per week compared to the floor typical of concrete per week.

The T3 office building in Minneapolis added another data point. The 7-story, 180,000 square meter building was compiled by a dozen wooden frames with a crane in about nine weeks. A concrete office of the same size would usually take four to five months and turn 50 to 70 commercial residents. The difference caused tenants to move in earlier, the costs for the bearing costs and the disruption of the surrounding neighborhood were limited.

Forté in Melbourne showed similar results. A five-person crew built the 10-story CLT building in 10 weeks. Concrete would have taken 20 to 24 weeks and needed at least 20 to 25 employees at the peak. Again, smaller crews, shorter schedules and cleaner locations emerged as consistent advantages.

The staff profile is one of the most important differences. Spreading concrete structures work on many shops. You need formwork, Rebar placer, pump operator, finisher, crane operator and general workers. Dozens of employees have to keep the cycle in motion. Mass wood breaks down a lot in fewer categories of higher skills. CNC operators and shop technicians cut panels in narrow tolerances in factories. On site, wooden frames and rigger work with crane operators to set pre -made elements. Project manager and 3D modelers coordinate sequencing and logistics. Instead of 50 or more workers who drive into a location and drive from the location, a single number of specialists can be twice as high.

The reduction in workers on site is usually 60 to 70 percent in the structure phase. At the same time, demand is moving to the production of locations where precision and digital skills are required. This creates different training needs. It also indicates the importance of a national skill program. If Canada wants to scale mass wood, it has to prepare thousands of 3D modelers, CNC operators and wooden frames, not just more general workers.

The Canadian cities already have to struggle with the lack of labor of construction work, and this reality shapes the prospects for mass wood. Large projects in Toronto, Vancouver and Calgary are often exposed to delays because there are not enough specialists available in several trades. Immigration and training programs did not keep up with demand, and the competition between infrastructure, living and commercial projects is intense. In this environment, an approach in which fewer employees are required and relocated more work to controlled factory environments has clear advantages. Mass wood reduces the dependence on the large concrete crews, which are in short supply and instead the demand for smaller, specialized teams and technical roles outside the locations that can be trained faster. This new compensation for work requirements could be one of the most important reasons for Canadian developers and political decision -makers to adopt mass wood on a scale.

Another promise of value that dives is the upward extension. The light weight of the mass wood makes it possible to add additional floors in existing buildings without much reinforcement. In the 80 m road in Washington, DC, three new wooden floors were built on a seven -story concrete office, with more than 100,000 square meters of being added. In Boston and New Haven, two tier CLT supplements were built on brick and radiation structures, which would have made concrete uneconomical. In Poissy, France, 33 new apartments on the roofs were built on the roofs of existing blocks on the roofs. In London, wood commitments on cultural heritage become a common way to create new space without tearing off the old. These projects avoid costly foundation -upgrades and tenant disorders and still offer high -quality living or office space.

The financial effects are clear. Rapid schedules reduce the time that finance the developers and bring the tenants into buildings earlier. Smaller crews reduce labor costs and location costs. Fewer truck deliveries and lighter structures lower foundation and sick costs. Up extensions open up a new market in cities where land is scarce and converted not used roofs into sales production. The advantages are not displayed in advertising material costs, but at the project level when time, money and disorder are stored.

These examples should be revealing for Canada. Mass wood is not only a climateol, but also a construction model that saves time and work. The country can apply these lessons to speed up the liberation of apartments, reduce costs and to compete and know how to export both panels worldwide and how. Obtain the fact that investments in skills and financial framework conditions are required that reflect the unique cost stack of the mass wood, and guidelines that make up the approving extensions more easily. The value is there. The question is whether Canada builds up the workforce and the strategy for recording.
