CANADIAN RESEARCH – Modular Assembly

 

Off-site construction distinguishes itself from traditional construction by offering shorter project timelines and potentially reduced costs. Furthermore, prefabricating some or all components inside a factory, allows not only to spend less time on the construction site, but also tends to improve the quality of buildings. Elements are built under controlled conditions, sheltered from the vagaries of weather, and where quality control can be performed more easily.

This type of construction would however benefit from a more efficient assembly solution to facilitate and accelerate the installation of the prefabricated elements on site, especially when it comes to large buildings. To address this challenge, Laurence Picard undertook a Ph.D. in mechanical engineering within the Industrialized Construction Initiative at Laval University, in Quebec City, under the supervision of Pierre Blanchet and André Bégin-Drolet. The objective of her project? To develop a self-locking connector to quickly connect prefabricated modules together on the building site, to optimize the benefits of prefabrication, especially for multi-story light-frame modular construction.

Today, when such prefabricated modules are erected on site, workers must perform certain manual operations to secure the hardware required to assemble the prefabricated elements. In addition to the time required to perform for this step, it also necessitates leaving certain areas of the modules accessible, i.e. unfinished, to carry out these interventions. This research project was therefore launched with the aim of optimizing this stage by developing a device to speed up the fastening of prefabricated elements together.

An exhaustive list of functional and technical design specifications has been established by the project team. Among these, the locking mechanism had to be automated, had to follow a vertical movement and the device had to be easily manufactured in a factory. There had to be a visual or sound confirmation of the connection, while unlocking of the connecting device had to be possible and performed in less than 3 min. Furthermore, the connecting device had to be located inside the walls and floors to allow for module completion, also the building’s vertical-compressive load paths could not be affected by the connector. Finally, the tensile capacity had to be at least 200 kN, while the compressive capacity had to be at least 1000 kN and the shear capacity had to be at least 40 kN. These design requirements acted as guidelines for the connector’s iterative design process. Computer-aided designs were generated, and digital simulations were performed during the design iteration process. Parts were then 3D printed for functionality testing, and finally prototypes were manufactured for experimental testing; steps that allowed to select the final design.

This design process led to the development of a self-locking connector consisting of two main elements, the floor connector and the ceiling connector. The first one, attached to the main floor beams, comprises the automatic locking box. The second, attached to the ceiling beam, comprises a shaft which rises upwards. When assembling the modules, as the upper module descends onto the lower module, the shaft is guided into the cylindrical cavity of the floor connector. When the shaft strikes the release block at the bottom end of the hole, the latch mechanism is deployed, and the connection completed (Figure 1).

Figure 1 Overview of the developed connector a) its main components b) the connection in process and c) in its final locked position (Source: Laurence Picard)

Once the development was completed, and before being able to use these connectors on real size buildings, they have been tested in the lab to evaluate their tensile, compressive and shear capacities, as the connectors support these types of loads in a building and contributes to the building’s load path. Connectors have shown sufficient performance in the lab to allow further development. They were then tested in operation, on steel jigs in the lab, and finally a full-scale implementation was performed on a real building. A total of twelve connectors were tested in a two-story house comprising four modules and a concrete basement (Figure 2).

Figure 2 Images of the large-scale test carried out with the connector on a two-story house (photo credit: Circerb)

This full-scale experiment allowed to evaluate the connector efficiency and its impact prior and during the installation of the modules on site. Overall, the experiment led to promising results, the connector offered a simple means of efficiently connecting modules together at the construction site. However, as expected, further refinement of the connector and its installation is required to optimize its use and take better advantage of the time savings it can offer. Regarding the design requirements that needed to be encountered by the device, observations during on-site implementation led to several conclusions. Among the characteristics that were judged to be satisfactory, first the parallelism of the module with the ground was attainable and adequate to avoid interference during descent. The module flexibility was sufficient to compensate differences between ceiling and floor dimensions, leading to a smooth shaft insertion for all twelve connectors. The conic surface of the connectors allowed to guide the descent and positioning of the module for an easier and accurate connection process. Moreover, the lifting movements did not impact the module interior finish, i.e. no finish defects were observed inside the modules after installation.

On the other side, some challenges were observed on site, regarding the success of the connections and the sound indication, confirming the connections. The analysis of cameras footage and the visual observations of the workers confirmed that the shafts of the ceiling connector did enter smoothly in the floor connector for all twelve ACDs. However, the connection was incomplete for most connectors (2/12). This was attributed to missing vertical displacement leading to an incomplete shaft insertion in the connector and therefore impartial engagement of the grippers. These placement problems can be explained by the fact that the positioning prescribed in the production plans for the installation did not consider unpredictable dimensional variations caused by moisture content and creep when the modules were stored outside on trestles for a long period. We can expect that on a regular project, with a higher control of these elements, the dimensional changes would be less of a problem, leading to a higher rate of connection. Moreover, according to the scientific literature, the risk associated to incomplete connections is limited regarding the structural behaviour of the building, for instance during a seism. In other words, even if the connection is incomplete, the connector fulfils its role in connecting the modules, ensuring most of its structural functions.

Regarding the time saved using connectors on site, it was difficult to evaluate in this context of innovation. First, when implementing new practices, the novelty of the project contributes to longer realization times. Moreover, since it was carried out as part of a scientific study, many measurements and observations had to be done by the research team, thus slowing down operations. But because of their quick automated connection and because of the higher level of completion they allow, it is expected that they will allow to greatly reduce the building erection time when they become commonly used in prefab modular projects. However, in this full-scale project, because of the novelty of their use, their installation on the modules at the prefabrication plant took a considerable amount of time. It requires an extensive dimensional control for the accurate positioning of ceiling and floor connectors, so that the two parts can precisely be inserted into each other on site. It can be anticipated that the time required to install them in the plant will decrease with experience and with the development of more automated installation techniques.

Figure 3 Possible configurations for the automated connecting and lifting device (Source: Laurence Picard)

The use of the developed connectors as attachment points for modular handling and lifting was also investigated during this full-scale experiment to evaluate the pros and cons of combining connecting and lifting functions in a single device. Handling the modules on site presents its technical challenge, the assembly process must adhere to a safe and efficient lifting procedure, ensuring minimal deformation of the lifted module to preserve both its structural integrity and its aesthetics. Consequently, for the developed connector to have a lifting function as well, new pieces, such as lifting rods, eyebolt and plates, were added to the connector design (Figure 3).

Their use in this two-story residential home allowed to evaluate their performance in application. Beneficial and challenging elements have been identified. A first challenge was encounter when positioning these devices within the structure. Traditionally, temporary lifting threaded rods are installed at the plant, during the module manufacture, but once the module in place on site, they are un-screwed and removed from the structure. Therefore, their positioning is not critical. In the case of the permanent rods developed in this project, their presence has led to considerable constraints in the architectural and structural design because these lifting rods had to be hidden in the wall.

Once this positioning challenge was overcome, they did perform well on site. Researchers considered that the lifting activities were successful, while the workers did appreciate using this new method. Lifting by four eyebolts has proven to be very efficient and appreciated by the workers who considered that it is an easier attaching option, compared to traditional practices.

Nevertheless, because of their restrictive impact on the building design, because of the lower-than-expected time savings allowed by their use, compared to the traditional lifting method, and because of their higher prices since they cannot be reused in other projects just like traditional rods, the researchers concluded that this specific design is not recommended for future projects. Future research and development work could however optimize the device’s design to improve their balance sheet.

 

Conclusion

In summary, this research project led to the development of an innovant and promising connecting device for light frame modular buildings. As for any technology in development, work still needs to be done in order to optimize its use for the prefabrication industry. But it offers several advantages that motivate further development. The developed automated connector can boost efficiency increasing the module level of completion, reducing manual labor and potentially assembly time, while ensuring precise connections between modular elements. It however necessitates an initial investment and introduces complexities in dimensional control during off-site installation. Moreover, on-site perturbations, like fluctuations in moisture content and storage conditions, can affect the success rate of the connections. The industry will need to adapt its practices for the effective adoption of the connection, particularly for the dimensional control of modules.

Combining the connecting and lifting functions in a single device on its side led to the conclusion that the device should be mainly used for its connecting function. The connector itself has a limited impact on the architecture of the buildings as they are hidden in the flooring and ceiling systems with other mechanical components such as HVAC, electrical and plumbing elements. Conversely, implementing the lifting axes induced many additional design constraints in the project that impacted the feasibility of some floor layouts.

A patent has been obtained for the connector developed. It has been licensed for commercial use by a company.

INDIA: Pollution Halts Construction

 

The Delhi government halted construction activities after the capital city was plunged

into an air catastrophe and imposed restrictions on vehicle use.

India‘s Supreme Court on Friday mandated a halt in crop residue burning in Delhi’s neighbouring states amid worsening air pollution in the national capital.

Heavy overnight rains brought some relief to millions struggling to cope as a toxic haze blanketed the National Capital Region (NCR) for more than a week due to the annual air crisis triggered by pollution, farm fires, and poor weather conditions.

“God may have heard the prayers of people and intervened, no thanks to the government,” said Supreme Court justice Sanjay Kishan Kaul.

The rains brought down the Air Quality Index (AQI) readings from 400+ to around 160.

Talking about the farm fires which have often been blamed as one of the leading factors behind the pollution, the court said the society needs to be responsive to farmers’ needs, while farm owners also need to be more responsible as they are a part of the society.

“The farm fires must stop. It’s your business how it occurs… The decline must go on during the Diwali holidays,” the court said, as reported by Bar and Bench. The matter has been posted for 21 November.

“People cannot be made to die,” the court noted on Friday, two days before Diwali festival in the country when experts are speculating a major hit to the air in the city from firecrackers and rising pollution levels.

“The pollution level must come down, it cannot await tomorrow (sic),” the court noted, and ordered governments of northern Indian states to take action.

Delhi’s air is engulfed with smog as courts are forced to intervene amid abysmal policy action from federal and state governments. Doctors have warned of rising cases of respiratory illnesses and shortening of life spans caused by the air pollution.

Every year the city shuts all schools and sends millions of children indoors to avoid exposure to the air which doctors have said is akin to “smoking 25-30 cigarettes per day”. The Delhi government halted construction activities after the capital city was plunged into an air catastrophe and imposed restrictions on vehicle use.

In a new solution this year, the city’s leaders were looking to induce artificial rain around 20 November depending on legal approval and weather conditions.

“There is a possibility that, if current weather conditions persist, then this week or till some time in the future the pollution situation will remain the same,” Delhi’s environment minister Gopal Rai said.

“I believe that given the conditions we have and if we get support from everyone, we can do the first pilot at least,” he said.

The administration wants to seed clouds with substances like silver iodine to induce precipitation. This artificial rain will help bring down the trapped air pollutants, officials claim.

Schlüter creates another statement bathroom

Schlüter Systems offers more than 10,000 products for the long-lasting installation of tiles and natural stone; they include a comprehensive range of trims, waterproofing, underfloor heating and shower drainage systems.  Worldwide, the products and systems have created the very best in bathroom design; in both style and durability.

 One such example is a renovation and extension project which included the refurbishment of the residence’s 4.8m x 2.7m master en-suite. Enlisting the services of Quell Bathrooms, the client set out the fundamentals of what he wanted – bath, shower and double basin with storage. He then gave free rein to Vincent Pope, Quell’s MD, to come up with a few ideas from which the final design was selected.  The resulting wetroom utilised a number of different Schlüter-Systems products in order to ensure a sound finish for the client’s considerable investment.

An integrated linear drain wetroom kit, Schlüter-KERDI-LINE-WRKL, was used to provide guaranteed waterproofing and drainage for the bathroom; it consisted of a waterproofing and sealing kit, shower boards, drainage channel and support with a tile support grate.

The waterproofing and sealing kit contained Schlüter-KERDI waterproofing membrane, plus Schlüter-KERDI-KEBA sealing band, Schlüter-KERDI-KERECK pre-formed corner pieces and Schlüter-KERDI-COLL sealing adhesive. The KERDI membrane from the kit was used to waterproof the back wall and around the shower wall. The rest of the room utilised Schlüter-KERDI-BOARD waterproof backerboard in 10mm thickness. All joints and junctions were sealed with the aforementioned set of sealing products. The 800mm linear drainage channel was installed in an intermediate location, sloped to from both sides using the Schlüter-KERDI-SHOWER-L and Schlüter-KERDI-SHOWER-LS pre-sloped shower boards. The drain was designed to be tiled to in-line with the rest of the floor – in this case with wood-effect tiles – resulting in a discreet solution.

‘Since we started using Schlüter’s wetroom kits three years’ ago, we’ve had none of the problems we would get previously”, says Vincent, “We wouldn’t deviate from them now as they offer a comprehensive and trustworthy solution to prepping a wetroom. The timber floors of the project had already been insulated, so Vincent installed the original Schlüter-DITRA-HEAT-E electric underfloor heating system. “It’s great that you can use this system throughout the whole of a room, including the shower area. Often this isn’t an option,” says Vincent who continues, “In refurbishment work, it’s always a struggle to keep floor build-ups low; with the Schlüter-DITRA-HEAT-E system, all build-up is contained within the height of the membrane so there are no unexpected surprises”.

Vincent used chrome-plated brass finishing profiles, Schlüter-QUADEC-MC, to provide finishing against the wood-effect wall tiles. He also used the matching Schlüter-QUADEC-MC/EV corner pieces to finish the corners of the one-metre high shower wall.

“Schlüter trims give a great finish for tile edges and neatly cover the edge of tile. In addition, the corner pieces provide a good-looking finish that avoids sharp edges which is important as we were finishing a low wall that could be a source of injury if finished with mitring” concludes Vincent.

Schlüter-JOLLY-AC in a Matte Brilliant White (MBW) finish was used to finish edges in wall areas where 1000mm x 330mm ceramic tiles were installed, including around window reveals. Three quarters of the edges of Quell’s custom-built niches for the project were also edged with the MBW trims, with QUADEC-MC to the inside edge of each as part of a wood-effect feature shower wall.

James continues,

“The flexibility of the S3 system allows landlords and developers to reconfigure zones, add extra devices in with limited changes to the initial install meaning upgrades in functionality come at a greatly reduced cost.”

 

The only open-source solar shading system that can reduce building energy usage and raise environmental impact and sustainability credentials, S3 delivers against seven key benefits, and exemplifies the Guidehouse* [2021] study’s assertion that “solar shading, specifically dynamic solar shading, is a key energy efficiency measure for a cost-effective improvement of the energy performance of buildings.”

The S3 System can be designed to allow diffuse daylight into the building while blocking direct sunlight. By optimising natural lighting, artificial lighting needs can be reduced, resulting in lower electricity consumption and associated CO2 emissions. With our automated blind system, it can be utilised as part of a daylight harvesting strategy. The blinds can work in tandem with light sensors to maintain a desired level of daylight in a space. When the sensors detect sufficient natural light, the blinds can adjust to balance the daylight and supplement with artificial lighting only when necessary. This approach optimising energy usage by minimising the use of electric lighting during daylight hours. Reduced Cooling Load Automated blinds when connected to an S3 System can be programmed to close or adjust their position during periods of intense sunlight or high outdoor temperatures. By blocking or shading windows, they prevent direct sunlight from entering the building, which significantly reduces heat gain. This is particularly important with regards to complying with Part O and Part L of the Building Regulations.

The S3 system helps to maintain cooler indoor temperatures and therefore reduces the need for excessive cooling, leading to energy savings and lower CO2 emissions. By integrating S3 with building management systems, you can be synchronised with other building systems like HVAC (heating, ventilation, and air conditioning). The blinds can automatically adjust their position based on the cooling requirements of the space, ensuring optimal thermal comfort while minimising energy consumption and CO2 emissions

The open protocol nature of the system is designed to be independent of any fixed supply chain, meaning all the components of the system are interchangeable with any SMI/KNX devices on the marketplace, and any KNX engineers with suitable training can maintain and upgrade the system. This is designed to give the client complete control of their building. The system is also fully digital meaning any changes to switching and zoning are software based. Once you have the Core of an S3 system in place there is never a need for further disruptive and expensive wiring for any changes, ensuring the open-source system is fit for the future.

TRILUX ILLUMINATES 2 MORE LONDON: DELIVERING A PREMIUM GRADE CAT A LIGHTING FIT-OUT

As London’s skyline evolves, 2 More London is a space where innovation meets inspiration, powered by TRILUX lighting excellence.

In the bustling heart of London’s South Bank, amidst the iconic skyline between London Bridge and Tower Bridge, lies 2 More London—a contemporary hub for office space. Recently revitalised, the third floor of this landmark underwent a CAT A fit-out, setting new workplace design and sustainability standards. TRILUX, renowned for its technical lighting expertise, played a pivotal role in illuminating this prestigious project.

The Vision: Clean lines to blend in, quality to stand out

As a hub for business and creativity, 2 More London demanded a lighting solution that not only met the highest efficiency standards but also didn’t disappoint aesthetically. Led by the consultancy Chapman BDSP, the project aimed to create a workspace that attracts the highest-quality tenants, showcasing the architectural aesthetic against the stunning London backdrop.

The Challenge: Transforming Space with Precision

According to the latest figures published by Savills, 91 per cent of all newly leased space in the City of London for the year to June 23 was grade-A compared with a 67 per cent long-term average pre-pandemic.

*Investor Chronicle September 2022

Here, we have 14,362 square feet of office space encased in floor-to-ceiling glazing; the project called for a high-quality lighting solution with minimal glare while maintaining consistency and energy efficiency. TRILUX rose to the challenge, working closely with Paul Earl Limited to implement their cutting-edge lighting products.

The Solution: TRILUX Lighting Excellence

TRILUX’s commitment to innovation and sustainability shone through in the selection of products. The Inperla Ligra Plus LED downlight, renowned for its easy-mounting and flexible design, was seamlessly integrated into existing ceiling cutouts. Sonnos LED downlights, provided exceptional quality light —a perfect fit for refurbishment requirements.

Notably, over 500 metres of bespoke LED light channel was the star of the show in the office space. This solution illuminated the vast expanse of office space, delivering both functionality and style.

The luminaires are highly recyclable, and the LED light channel can be reconfigured for specific tenants’ requirements and can be fully refurbished and reused in the future, reducing the carbon impact.

Luke Facer, Electrical Project Manager, Paul Earl Limited, says,

“Working on the Cat A at 2 More London was really exciting in such a sought-after location with outstanding views of the City and Tower Bridge from the 3rd floor; working with TRILUX was a pleasure, with exceptional communication from Vick and Gary, who were always on the phone to answer any queries or send any information that was requested by myself. The TRILUX light fittings themselves were of A1 quality and easy to assemble on-site with a sleek finish that really set off the hanging rafts that they were installed into.”

In a market where Grade A spaces redefine workplace standards, 2 More London strives for more: More freedom. More flexibility. More capability. More creativity. TRILUX’s lighting design and technology expertise played a vital role in shaping the future of the workspace —a fusion of efficiency, creativity, and sustainability.
