I would say quite directly. The correlation is probably quite strong as construction obviously relies a lot on workforce.
However another major limiting factor during construction is the availability of heavy equipement and formwork equipement, hence not only related to labor efficiency.
This is a rather dim answer but I hope this helps a bit...
This is very whole Question
but it depend on different criteria such as standard situation,standard time of work like 8hours per day,enough istrument and..etc
Labors efficiency matters in construction works. skilled and trained labors will deliver good product in short time. similarly young and energetic labor will give desired product in short time.
it depends on the level of building technology you use ,,
For tranditional or intermediate BT, you really depend on skilled labour , as there is no place for machinery in this level.
Then, if it was advanced or high-tech, you just need well trained labours or Operators, they are just making assemblies or operating robots or a machine to do it ,, so the type of "skill " is not the same.
finally , it depends on the type of skill needed compared to type of BT level.
There is indeed a direct correlation between labor productively the performance of construction activities, such as delivery of project on time and within budget. This is without prejudice to the fact that the construction activities involve the deployment of heavy equipment or skill labor intensive only; after all the machinery and equipment do not operate themselves in a vacuum.
Where construction productively is established as measure of man-hours spent to achieve a target progress, it implies that one can make a conservative estimate that more 50% of construction productivity could be impacted solely by efficiency of labor ….
There is also a relationship between the number of repetitions of an activity by the worker and the productivity gains, the worker will acquire some of a gain in productivity or skill. There is a relationship which gives us the relation between the number of repetition and duration.
Construction productivity is directly linked with the effectiveness of the workforce. More the productive workforce are more the productive are constructions. The trained and skilled workforce reduce the time of working as compared to unskilled workforce. Hence there is savings in time, cost and improvement in quality.
it dipends on how much labor effect on your costruction,imeans that whats the portion of using labor or machinery and its different d construction type but i think 50% its good and i deal but skillful labor and 30% management and 20% machinery and instrument
Some construction activities are heavily labour-intensive and would be more affected by improved labour productivity. However, there are also plant-driven activities which would be less affected. There are also activities in construction which are logically significant (similar in some ways to the Theory of Constraints) which must be done at a particular time in a particular way, so improving labour productivity alone without addressing the logically significant activities may have limited impact on the overall productivity
The University of Dundee (Construction Management Research Unit) have been studying construction productivity for 25 years and will probably be able to point you in the direction of published articles addressing this issue. Prof Malcolm Horner would be the best contact there. My MSc Thesis was published there in 2001
