Modular Integrated Construction (MiC) is an innovative construction method. By adopting the concept of “factory assembly followed by on-site installation”, MiC helps to ease some of the current challenges faced by the local construction industry. In this method, free-standing integrated modules (completed with finishes, fixtures and fittings) are manufactured and assembled in a factory. By transferring on-site construction processes to a controlled factory environment, buildings can be substantially completed off-site. The adverse impacts of weather conditions, scarce labour resources and site constraints can all be substantially reduced. MiC provides a great degree of production quality control, and can improve construction productivity, safety and sustainability.

1. Project Design

• Early engagement of module supplier and local contractor is needed
• Design needs to be completed at an early stage

2. Seeking Statutory Approvals

• The design needs to comply with the Buildings Ordinance and/or other relevant requirements (e.g. PNAP ADV-36 ) and procedures

3. Production of Modules

• Mock-ups and prototypes of each type of module are fabricated, checked and tested before mass production
• Trial assembly/stacking of modules in the factory should be carried out
• On-site construction activities, such as piling/foundation works, external underground utility works, etc., can be carried out concurrently

4. Transportation of Modules to Site

• Special traffic arrangement needs to be made for transportation of modular units with width larger than 2.5 meters
• Temporary storage location may need to be arranged, subject to the delivery and construction programme

5. On-site Installation

• Upon stacking of modules, temporary waterproofing is required to be carried out before completion of permanent waterproofing
• Connection of module to module/module to core parts (Structural and Mechanical, Electrical & Plumping Systems) needs to be made

Prefabrication Components

• Prefabricated components only comprise small parts of a building
• Structural parts other than prefabricated components still need to be built using conventional construction methods
• Substantial amount of formwork, steel fixing, and concreting works are involved
• Interior decoration and laying of pipes, etc., could only be carried out thereafter

Common Prefabrication Components in Building Works

• Prefabricated Facades
• Prefabricated Slabs
• Prefabricated Walls
• Prefabricated Staircases
• Semi-prefabricated Slabs
• Prefabricated Bathrooms

Modular Integrated Construction

MiC is an innovative construction method. By using MiC, the building is substantially completed off-site. This can reduce on-site construction processes and enhance site safety, hence achieving higher productivity.

1. Free-standing integrated modules (completed with finishes, fixtures and fittings) manufactured in a factory
2. Modules transported to construction site
3. Modules installed to form a building

Various Types of MiC

• Reinforced concrete modules
• Steel frame modules
• Hybrid modules
