PRODUCTIVITY
Productivity is achieved by maximizing the number of units produced in each time frame.
FACTORS SERIOUSLY IMPAIRING CONSTRUCTION PRODUCTIVITY;
Pandemic – Restricted working.
- Project Conditions – Weather variability.
- Market Conditions – Material shortages & lack of experienced design and project management personnel.
- Design & Procurement – Large number of changes.
- Construction Management – Ineffective communications inadequate planning and scheduling Lack of sufficient supervisory training.
- Labour – Restrictive union rules and lack of incentive.
- Government Policy – Slow approvals and issue of permits.
- Education and Training – Lack of management training for supervision, project management.
LABOUR EFFECTIVENESS
To improve labour effectiveness, various factors can be addressed, including motivation, job safety, environmental factors, and physical limitations. Management practices include scheduling, planning, data collection, job analysis, and control. Material timeliness is ensured by proper procurement scheduling, site layout, and other issues.
The SP (100 rating on the BS scale) is the standard of effectiveness that is desirable for the operative to obtain if your organization is to remain competitive in the construction industry. Statistically the average operative works at 75 rating. For planning or estimating purposes the SP value would not be used but some value up to a 75 rating.
The production rates we use have been gathered over a period of over 70 years covering: Site Services, Ground Works, Sub-Structure, Super – Structure, Finishes, External Works, Infrastructure & Miscellaneous.
If calculating a Bonus target, Standard Time (assuming PE is 100%) should be increased by 25% to create a realistic margin for the gang to earn a bonus, the target being to achieve normal Standard Time performance levels.
Standard Time is an approximate guide and already incorporates natural break (meals, welfare, etc). It does not include any allowances for delays, lack of continuity or inadequate supplies which remain the sole responsibility of site management.
In calculating bonuses, site conditions must be accurately recorded so, for instance, if a gang spends 3 hours laying bricks and three hours awaiting supplies, the allocation should show laying bricks as 3 hours, standing time 3 hours, and not laying bricks 6 hours.
Performance will largely depend on whether there is an incentive scheme in operation, by the type of work being carried out, and by the effectiveness of the on-site supervision.
The heart of The Construction Library is a totally new kind of production rate database, based on Work Study research conducted on sites since the 1950’s. It offers project managers the tools to create a robust programme based on realistic, measured output rates for the first time. Measured rates mean a programme with greater certainty, credibility and resource efficiency; we believe it will change the way people plan construction projects.
The production rates we use have been gathered over a period of 70 years covering: site services, ground and civil works, sub-structure, super-structure, finishes, external works, infrastructure and miscellaneous.
We are not at liberty to openly advertise the production rates; however, dependent upon your need please get in touch and we will help you.
