INTRODUCTION Construction is the world's largest and most challenging
industry. The value and demand for the construction projects of any
organization mainly depend on efficiency of the labour and it play an important role towards
the improvement of the productivity. Labour is an most important and valuable part of
any construction industry and unfortunately most of the industries in fact all are neglecting
that part, due to this reason may be most of the construction industry facing a challenges with
regarding to problem associated with the productivity of labour. Productivity is the one of the most important factor that affects
overall performance of any small or medium or large construction
industry. There are number of factors that directly affect the productivity of labour, thus it is
important for any organization to study and identify those factors and take an appropriate action
for improving the labour productivity

OBJECTIVES
In this project work it is proposed to do the following work - To study the different factors affecting the productivity of the
labour. To analyze all factors. Identifying all the critical factors depending upon the volume of
work. Deciding the methodology for improving the labour productivity.

LITERATURE REVIEW
In this the various factors influencing the labour productivity in turkey are Determined,
Defined and Examined in detail. A survey was applied to 8 firms to obtain required data, then
according to results the most effective factors group is organized.
Construction industry faces challenges with regard to problems associated with productivity
and the problems are usually associated with performance of labour. The performance of labour
is affected by many factors and is usually linked to the performance of time, cost, and quality.
Poor productivity of construction workers is one of the causes of cost and time overruns in
construction projects. The productivity of labour is particularly important especially in
developing countries, where most of the building construction work is still on manual basis.

TOP 10 FACTORES AFFECTING LABOUR PRODUCTIVITY
1. Incompetent supervisors 2. Lack of skills from the workers 3. Rework, lack of tools and equipment 4. Poor construction methods 5. Poor communication 6. Inaccurate drawings 7. Stoppage because of work being rejected by a consultant 8. Tools/ equipment breakdown. 9. harsh weather condition. 10.Delay in arrival of material.
5
WHAT IS LABOUR PRODUCTIVITY ?
Productivity can be defined in many ways. In construction, productivity is
usually taken to mean labour productivity, that is, units of work placed or produced per manhour.
The inverse of labour productivity, man-hours per unit (unit rate), is also commonly used.
Productivity is the ratio of output to all or some of the resources used to produce
that output. Output can be homogenous or heterogeneous. Resources comprise: labour, capital,
energy, raw materials, etc. Productivity = Output Resources used
6
MATHEMATICALY IT IS REPRESENT AS
At the project site, contractors are often interested in labor
productivity. It can be defined in one of the following ways - Labour Productivity = Output Labour cost OR Labour Productivity = Output Work hour There is no standard definition of productivity and some
contractors use the inverse of above , Labour Productivity = Labour cost / work hour Output
7
VARIOUS FACTORS AFFECTING LABOUR PRODUCTIVITY
Based on the studies, Factors affecting construction labour have been identified and were grouped
into 15 groups according to their characteristics, namely : 1. Design factors 2. Execution plan factors 3. Material factors 4. Equipment factors 5. Labour factors 6. Health and safety factors 7. Supervision factors 8. Working time factors 9. Project factors 10.Quality factors 11.Financial factors 12.Leadership and coordination factors 13.Organization factors 14.Owner/consultant factors 15.External factors
8
THE TOP TEN FACTORS THAT AFFECT THE SMALL AND MEDIUM COMPANY
1. Lack of material 2. Labour strikes 3. Delay in arrival of materials 4. Financial difficulties of the owner 5. Unclear instruction to labourer and high absenteeism of
labours 6. Bad weather (e.g. rain, heat,etc.) 7. Non discipline labour and use of alcohol and drugs 8. No supervision method, design changes, repairs and
repetition of work, and bad resources management 9. Bad supervisors absenteeism and far away from location of
material storage, and 10. Bad leadership
9
THE TOP TEN FACTORS THAT AFFECT LARGE COMPANIES
1. Unclear instruction to laboure 2. Delay in arrival of materials, 3. Lack of material and financial difficulties of the owner, 4. There is no definite schedule, 5. Low supervisor’s capability/incompetence supervisors, 6. No supervision method, lack of equipment, and high
absenteeism of labours, 7. Supervisors absenteeism, frequent damage of equipments,
and labour strikes, 8. Design changes, 9. Incomplete drawing and inspection delay, 10. Poor communication in site and inaccurate design.

FACTORS THAT AFFECT IN GENERAL ALL
1. Lack of material, 2. Delay in arrival of materials 3. Unclear instruction to laboure, 4. Labour strikes, 5. Financial difficulties of the owner, 6. High absenteeism of labours, 7. No supervision method, 8. Supervisors absenteeism, 9. Lack of equipment and design changes, 10. There is no definite schedule. 11. Poor management 12. Unproductive time ( internal delay, extra break, waiting &
relaxation )
11 13. Lack of skill
14. Supervision delay 15. Lack of tools & equipment 16. Poor instructions 17. Poor quality of labour 18. Supervision factor 19. Material factor 20. Execution plan factor 21. Health & safety factors 22. Labour shortages 23. Working time factor 24. Accident
12 There has been much work identifying the factor that affects
productivity. Ineffective management
has been cited as a primary cause of low productivity rather than other factors. Apart from that
there are also some barriers to improve the productivity and these barriers are as follows :
Lack of alignment of goal Contractual conflict Difficulties in measuring productivity Weak commitment to continuous improvement Lack of labour force focus
13
GUIDELINES FOR IMPROVING THE LABOUR PRODUCTIVITY
1 Properly training to the labourers 2 Motivation to workers towards project completion 3 Properly and in advance material procurement and
management 4 On time payment to the workers 5 Systematic flow of work 6 Properly , clearly & in time supervision 7 Advance site layout
14 8 Maintain work discipline
9 Facilities to the labourers 10 Clearance of legal documents before starting of work 11 Systematic planning of funds in advance 12 Premansoon plan to avoid work stop 13 Maximum use of machinery and automation system 14 Advance equipment planning

METHODS TO IMPROVE LABOUR PRODUCTIVITY
1.Quality of site management Improving productivity could be best carried out by means of
development in management quality. Namely, the principal difference in
construction productivity is the management influence. Stages of estimating construction time
and cost reliably, where the knowledge of labour productivity takes a considerable part, are
the main items of successful management understanding. In the study of Sandino ineffective
management was cited as the primary cause of poor productivity rather than unmotivated or
unskilled manpower. One of the primary means of rising worker productivity through
management is to procure and control adequate working conditions since productivity in
construction is greatly affected by work conditions that change from project to project.
16
MATERIAL MANGAMET Problems with adverse material management conditions that
consist of supplying and shipping have been cited in the literature among major causes of
productivity loss. Effective material management systems are counted as taking measures
against fluctuations in material prices, informing vendors or fabricators precisely concerning the desired
material features, and suitable material planning and organization, i.e. logistics management.
The problems that can be appeared in material management applications are the following: • running out of materials, • Extensive multiple-handling of materials, • Improperly sorted or marked materials, which makes to define
them difficult, • Wrong or damaged materials that exceed acceptable
specification tolerances, or production errors pointing to a poor quality, • Unsystematic flow of materials • Production rates of materials in plant incongruous with those on
site.
17
OF PAY AND ON-TIME PAYMENT
Remuneration is seen as the most important reason of why an
individual has to work in a job. Because it both meets the physiological needs that
are the most basic requirement of people, and gives esteem in a society. The
amount of pay and on-time payment is the most vital factors required to meet the first hierarchy need
of Maslow.
18
FLOW OF WORK (PLANNING)
Judicious planning of labour resources are the foremost agent in fulfilling these
constraints. Poor planning, however, can adversely affect labour productivity through the need
for rework and can result in lost time for workers, since operatives are often paid on work done
satisfactorily alone.
19
SUPERVISION To follow-up and supervise labour while working is a vital aspect
of any organization because both it can result in extensions of project
time and cost, and the quality on site is controlled through inspection of the work completed by the
gang. Supervisors’ communication with labour has a supreme importance as well. It
is a fact that workers feel embarrassed and pressed with the existence of tight audits.
Multiple tiers of field supervision reduce overall crew efficiency.
20
SITE LAYOUT
Layout can influence productivity and enhance space management capability. It
defines the location of the tools and supporting utilities for optimum product flow, and thus has
a direct impact on the facilities’ time and cost of construction. In this context, the location of
the management office has a strategic importance as well as worker dormitories on site,
especially there are many shifts that may cause loud noise and thus a possibility to sleep.
21
WORK DISCIPLINE
One of the primary conditions for improving systematic working habits is to have a
complete work discipline on site. Discipline can be defined as a concept that determines the
human being behavior by means of reward or punishment. This concept becomes more
important in Turkey, since workers in the construction sector are still composed of individuals
coming from the rigid regions of patriarchal society.
22
OCCUPATIONAL EDUCATION AND TRAINING
Vocational education, particularly in developing countries, is the total of activities,
which enable the reasonable employment of unskilled labour by educating and directing them
to vacant fields of labour market, to regulate and control those who come from farming and do
not have any continuous working habit. Poor productivity and high costs in every branch of
industry are due partly to low levels of training.
23
WORKING AT SIMILAR ACTIVITES
To work constantly in the same or similar activities in the construction sector, where
tasks vary in a very wide spectrum, or, in other words, to have a complete experience in one
trade is one of the key elements guaranteeing the work to be performed by a worker in a
definite standard. Experience is the warranty of success and productivity in any job. Working
with experienced crews in the sector has many advantages. If experienced labour is known to
be available, supervisors do not have to explain details of how to perform the tasks to
experienced workers.
24
CONCLUSION
The groups of factors which are highly effective are: supervision, material, execution
plan, and design. Moreover, for large companies, equipment factors have also highly effective.
While in small and medium companies, owner/consultant factors also need special attention
because it has high effect too. Research findings also show that health and safety factors has
not been a concern of small, medium companies and has some effect, while in large companies
are better, although not as major concern and has average effect.
Practically it is difficult task to all to improve labour productivity up to 100%. But if
you have properly control on above factors, productivity can be improved up to large extent
