Lean Construction - Definition Lean construction is an
adaptation of lean production techniques applied to the
construction industry (Lacatelli et al., 2013) It is about managing
and improving the construction process to profitably deliver what
the customer needs Lean production can be identified as the
application of minimal buffers and materials to stock and delivery
of components in factory settings to ensure that the production
line is more efficiently managed to reduce overall cost (Berggren,
1990) Newessays.co.uk Sample
Slide 5
Research Background Efforts to spread awareness of the concept
of lean construction have been going on since 1998 in the UK Common
et al. (2000) argue that in spite of the continuous efforts to
spread awareness in the UK of the concept of lean construction,
large UK based construction firms have not shown an inclination to
adopt lean construction and management practices There exists a
much bigger gap when it comes to the number of researches that have
delved into lean construction practices in the UK when compared to
other countries Newessays.co.uk Sample
Slide 6
Aims of the Study To identify the determinants (both benefits
and barriers) of lean construction from existing literature To
determine the impact of benefits of lean construction on
construction buildability To assess the impact of negative factors
which reduce the impact of lean construction and construction
project buildability To provide recommendations to overcome the
negatives of lean construction management Newessays.co.uk

Slide 8
Lean Management According to Liker (2004) and Womack and Jones
(1996), the concept of lean production and management can be
examined from the perspective of the following attributes:
Strategic management Efforts undertaken to increase focus on
customer value and resource efficiency Cross functional teams which
can function with cross disciplinary talent Simultaneous or
concurrent development of multiple systems and subsystems
Production approach aimed at ensuring that a larger subsystem can
be promoted with a higher level of supplier involvement

Benefits of Lean Construction Strategic management of project
and minimisation of project rework Reduces the cost of construction
project Increase in project quality and value Newessays.co.uk

Slide 10
Weaknesses of Lean Construction Fragmentation of the UK
construction industry This has resulted in the need to
differentiate between lean principle application across other
industries and the construction industry in the UK Culture and
labour The inherent fragmented nature of the construction industry
has resulted in the growth of a static and hierarchical
organisational structure Newessays.co.uk Sample

Research Methodology Newessays.co.uk Sample
Slide 12
Research Design Research Philosophy Positivism This philosophy
is used as the study primarily engages in collecting data from an
objective point without interrupting the phenomenon involved
Research Approach - Deductive This approach is used as it verifies
if a given theory is credible in a given situation Research
Strategy Survey Research Method - Quantitative Newessays.co.uk

Data Collection Methods of Data Collection - Questionnaires
Time horizon - Cross sectional Sampling method - Convenience
sampling Pilot Study is conducted among a group of researchers and
the research study is verified in terms of reliability and validity

Slide 14
Data Analysis Saunders et al. (2011) assert that the use of a
questionnaire requires a quantitative data analysis using
statistical tools In the current research, quantitative data
analysis is promoted using the SPSS Version 21.0 software

Slide 16
Analysis of Participants Demographics Analysis of the results
from the survey showed that: Most of the respondents were between
the age of 20-29 (28.3%) or 30-39 years (35%) Most of the
respondents were men (82.5%) rather than women (17.5%) Most of the
respondents have been in the industry for more than 5-10 years
(37.5%) or 4-5 years (33.3%) Newessays.co.uk Sample
Slide 17
Analysis of Knowledge and Practice of Lean Construction It is
argued that there is no significant association between their
knowledge and practice. This is because 80% of respondents who
identified that they have limited knowledge of lean construction
also identified that they did not practice lean construction
principles. At the same time, 30.8% of respondents who had vague
knowledge of lean construction principles were found to have good
practice of lean construction. Most respondents indicate moderate
(25 respondents) to good (22 respondents) practice of lean
construction. Few of the construction managers presented
interesting insights on this. They responded that the practice of
lean construction was a principle of the construction organisation
and that construction managers had limited say in the same

Slide 19
Analysis of Barriers to Lean Construction The analysis of the
results show that lack of flexibility, complexities in coordination
and management, difficulties associated with multiple stakeholder
involvement, difficulties in communication and the use of
subcontractors are definite barriers to the promotion of lean
construction The respondents also indicate that the lack of
exposure, difficulties in applying lean construction management
principles of manufacturing in construction, lack of HR development
in terms of lean construction and lack of training are definite
barriers to the promotion of lean construction The respondents
indicate that the lack of coordination between design and
construction, the presence of incomplete design and the lack of
control during design phase are definite barriers to the promotion
of lean construction Newessays.co.uk Sample
Slide 20
Benefits of Lean Construction The respondents indicate that the
setting of project scope at the design stage, clear identification
of objectives, maximisation of performance and the promotion of
stakeholder involvement at the design stage are definite benefits
which reduce project rework due to lean construction The
respondents also indicate that the promotion of waste reduction,
reduction in project uncertainty and project risk and reduction in
project delay are definite benefits which reduce project cost due
to lean construction Newessays.co.uk Sample
Slide 21
Impact on Project Buildability The results shows that only two
attributes are found to have a significant impact on construction
project buildability It is observed that human resource factors and
funding are found to negatively impact construction buildability
Project cost has a significant positive impact on construction

Recommendations The general recommendations identified from the
study results include: Investment in lean construction training
Promotion of greater awareness amongst the top and middle
management with respect to lean construction Improve the funding
given by private organisations to lean construction Provide a clear
definition of lean construction application throughout the project
Ensure that lean construction is part of the construction design
and procurement and involve multiple stakeholders Newessays.co.uk
