Safety
Safety
Experience has shown that compared to conventional construction, projects employing modular techniques achieve significantly better safety results measured in terms of total recordable and lost-time cases
More work done in a shop environment
Additional work fronts available at grade and less work performed at high elevation
Reduced time of working overhead
Reduced scaffold requirement
Reduced number of cranes and non-engineered lift activities. Heavy lifts are under more control with exclusion zones
Reduced site peak labour numbers
Compare site contractor historical performance with that of module yards
Work area is free and clear of typical site constraints
Cost
Cost
Transfer craft work-hours from field construction site to a modular assembly site producing lower unit labour costs and significantly greater labour productivity
Improved efficiencies result at the field site due to smaller labour force and lower work density
Controlled environment for most assembly work allowing craft labour to work regular hours without stoppage for inclement weather
Reduction of overheads, particularly camp costs, per diems and support facilities
Modules can be procured lump sum thereby increasing price certainty for a larger portion of the project scope
Lunch, toilets, materials, laydown areas, works shops all in close proximity allow for greater workforce efficiency
Schedule
Schedule
Higher productivity in a shop/yard environment
Modules are completely assembled, tested, painted, insulated, heat traced, pre-wired
Requires less time at the plant site as well as a significantly lower peak manpower level
Schedule reduction translates to project cost savings
Shop environment has established systems for procurement and material tracking
Shop has access to stock material and local suppliers for improved material delivery
Less affected by weather (with indoor facilities)
Additional services are close by eg Chemical Cleaning, specialised NDT Services etc
Quality
Quality
Shop environment lends itself to better quality control with established labour, methods, and quality control procedures
Smaller environment with better oversight
More qualified and consistent labour pool than remote project site where qualified labour may not be readily available
Specialists are more readily available than at a remote site
Quality control – perform extensive check-out and testing at the module fabrication shop which reduces mechanical completion items in the field
Cost and duration of inspections and corrective actions is low
Environment / Social
Environment / Social
Reduced footprint provide environmental value to company, community, country
Reduced high peak craft levels, created local environmental impact
Reduced transient population impact to local communities and environment
Standardised so that the design can be used as basis for future facilities
