DESIGN NAME: Meeting Impossible Challenge
PRIMARY FUNCTION: Quarantine Camps
INSPIRATION: Follow the outbreak of COVID-19, the Hong Kong construction industry demonstrated its unity, strength and concerted effort to help the community fight the disease. While the epidemic was raging across the world, the fight was a race against time. Collaborative support were given by various government departments to share a common goal: Together we fight COVID-19. Dedicated frontline workers also played vital part in the fight. It was an honor to fight the pandemic for the wellbeing of Hong Kong.
UNIQUE PROPERTIES / PROJECT DESCRIPTION: To fight the COVID-19 in Hong Kong, the need to provide quarantine camps could not be more urgent and was unprecedented. As a response to such an urgent need of the society, "Counting by hours" was the principle for project delivery. The timely construction of Quarantine Camps was made possible by using Modular Integrated Construction (MiC). At the peak of the project, some 900 workers were engaged on sites and on-site installation was done 7/24 and up to 44 units being installed a day.
OPERATION / FLOW / INTERACTION: The Quarantine Camps are currently accommodating people who are close contacts of confirmed cases, and people returning to Hong Kong from overseas countries or places requiring to stay at Quarantine Camps after risk assessment, but without compatible symptoms for compulsory quarantine. With strategic planning in response to COVID-19 outbreak, the design was based on infectious disease control criteria with special drainage system design. In consideration life-cycle sustainability, the design of MiC units has allowed for future transformation into other uses.
PROJECT DURATION AND LOCATION: The construction period of the four completed Quarantine Camps in Hong Kong are:
1.Commenced on 3 Feb 2020 and completed on 28 Feb 2020 at Upper Lei Yue Mun Park (26 days).
2.Commenced on 14 Feb 2020 and completed on 9 Apr 2020 at Lower Lei Yue Mun Park (56 days).
3.Commenced on 14 Feb 2020 and completed on 30 Apr 2020 at Sai Kung Outdoor Recreation Centre (77 days).
4.Commenced on 21 Feb 2020 and completed on 22 Apr 2020 at Pat Heung Junior Police Call Permanent Activity Centre (63 days).

PRODUCTION / REALIZATION TECHNOLOGY: Innovation is the key to drive forward productivity efficiency and enhanced project delivery outcomes. MiC is a game-changing disruptively–innovative approach in building construction. Off-site construction using MiC refers to complete off-site factory pre-construction of volumetric modules of buildings with finishes, buildings services & fittings, etc. and then transported to site for constructing buildings. With 24/7 operation for module production in factory and installation on site, the construction period was shortened significantly. Proven benefits also include improved site safety, more efficient, better quality control and longer lasting built assets, less construction waste, less demand for on-site labor and less construction nuisance.
SPECIFICATIONS / TECHNICAL PROPERTIES: The Quarantine Camps are located at four sites: -
1. Upper Lei Yue Mun Park: 118 units, 2.5m(W) x 6m(L) x 3m(H)
2. Lower Lei Yue Mun Park: 234 units, 3m(W) x 6m(L) x 3m(H)
3. Sai Kung Outdoor Recreation Centre: 99 units, 3m(W) x 6m(L) x 3m(H)
4. Pat Heung Junior Police Call Permanent Activity Centre: 120 units, 2.5m(W) x 6m(L) x 3m(H)

RESEARCH ABSTRACT: MiC is a construction method adopting the concept of “factory assembly followed by on-site installation”, to transform as far as practicable the conventional on-site construction method in the construction industry into modern industrial production under which the structural frames of buildings, interior fitting-outs, building services installations, etc. are pre-fabricated in factories and delivered to the construction sites for installation. At the onset of the project, standardized modular unit was the main design criteria of each Quarantine Camp which enabled the fast planning of the project. By transferring the on-site construction process to a controlled factory environment, the impacts of adverse weather conditions and site constraints that often affect on-site construction can be significantly minimised. This project is a fight against time, with the employment of MiC technology, we turn the Impossible Challenge into possible.
CHALLENGE: Time was the major challenge. By the time Architectural Services Department (ArchSD) was tasked to provide Quarantine Camps in late January 2020, factories in the mainland were closed for the Lunar New Year holiday and situation was worsen due to the resumption of production was deferred owing to the severity of the infection. Following the stringent worldwide lock down policies, arrangement had to be made with the local government in Mainland to grant special approval to allow workers to return to their position. Through high level collaboration between governments, factories were able to resume production with permission of local government. Situation was the same as in another factory in Malaysia, production was delayed because of the lockdown imposed to curb the outbreak. Despite the delay, the modules were produced on time. Notwithstanding the tight schedule, quality has never been compromised.
The logistics involved in transporting the voluminous modules to the sites from factories in China and Malaysia was another challenge to face with due to the lockdown concern as well as the local transportation restriction on the volume size limit which required road permit application. Special arrangements to facilitate smooth delivery of modules for both outbound and inbound challenges had to be made through collaboration among various government departments.
All quarantine units are designed to meet the high hygiene standard and infectious disease control criteria for quarantine use. ArchSD has completed 571 Quarantine Camp units in 3 months’ time and the Quarantine Camp units at the Upper and Lower Lei Yue Mun Park were completed in 624 hours and 1320 hours respectively. The use of MiC in Quarantine Camps provided an excellent example to showcase the fast and quality project delivery which also encompassed project planning, design, module production and installation monitoring. The projects also served to demonstrate the feasibility of a new mode of project delivery using innovative production technologies.
