The construction industry is a highly dynamic sector and an important player in the development
of any nation. Hence it is essential to ensure that the construction projects are completed
successfully in time, within budget and with expected quality. This research aims to compare the
trend of cost overruns in the public and private construction projects using Lagos State, Nigeria as
a case study. The objective is to provide knowledge that will enhance effective project delivery in
both public and private sectors. The study was carried out using the cross-sectional design and
adopted the quantitative research method. A questionnaire was administered to 130 sampled
professionals and clients out of which 92 respondents duly completed and returned, representing
71% response rate for the analysis. The study revealed that cost overruns in the public sector projects
were 19.14% on average and 19.63% in the private sector.
The T-test results revealed that there was no significant difference in the mean values of percentage
of cost overruns in the public and private sector projects respectively. Some of the most important
causes of cost overruns in the public and private sectors are additional work, poor project
management, contract administration, inflation and high interest rates on construction materials.
As a measure against cost overruns, this study advocates the need for properly defined project scope
from inception.

Delays and cost overruns should be drastically reduced at construction sites. It requires
investigation in the current practice with regard to the planning stage. This paper gives an
introduction to the US Naval handbook for planning and estimation, NAVFAC P-405; discusses
its merits and explains the need for extrapolating its current use, from a private code of US navy, to
a global audience of construction practitioners. The term 'platform independence' in provisions of
code is introduced. It is seen that this particular code is a platform independence-compatible code,
paving the way for its extended use worldwide. Further, a method to calculate overruns in a single
activity using NAVFAC-405 is explained with a live example from a site. A study of an Indian
construction site is done and data regarding time/cost overruns are calculated based on this code. It
is expected that implementing this code would bring uniformity and standardize overruns, paving
the way for proposing proper mitigation measures for overruns, which are a long overdue in the
construction industry.

Infrastructure projects like Bus-Rapid-Transit-System (BRTS) would have been made more
sustainable and environment-friendly by adopting the Clean Development Mechanism (CDM)
which has been focused in this work. The proposed methodology leading to a CDM framework has
been formulated by computing carbon footprint of the BRTS in a city in India. Emission
reduction by using the alternative fuel like biodiesel has been proposed. Further, the use of more
energy-consuming materials like cement and steel needs to be minimized. The use of flyash as part 2replacement of cement is recommended which would result in about 35 % reduction in CO
emission. It is computed that 9763.55 tonnes of the reduced clinker would result in about 4559.55 2 2tonnes of CO reduction. The reduced CO emission would result in about 2455.18 CER which
would qualify as a CDM project during the project extension phase. Also, it has been observed that 2the use of biodiesel to operate BRTS can reduce the CO emission by about 42% per year. As a
policy matter, it is strongly supported that the Annex-1 countries should transfer technology for
vehicle re-engineering leading to the improved fuel economy.

In this experimental investigation an attempt has been made to study the suitability of fly ash,
cement and sand in the preparation of stabilized laterite-soil bricks. Hence, the required number of
bricks were compressed with different proportions of material such as, 77% Laterite soil + 15%
sand + 5% fly ash + 3% cement; 75% Laterite soil + 15% sand + 5% fly ash + 5% cement, and
73% Laterite soil + 15% sand + 5% fly ash + 7% cement. The bricks were compressed using the
hydraulic press paver block and brick making machine, and tested as per the Indian standard
specification. The results of dry compressive strength, wet compressive strength and water
absorption were tabulated. Based on the obtained test results stabilized laterite soil bricks are more
stable than the traditional burnt bricks, resist higher compressive loads and having less water
absorbing capacity.

Road signs and markings are important for proper guidance and safe movement of traffic. The
road signs should be designed as per the IRC standards and should be provided at the right place. In
some of the locations of Bangalore city, even though the road signs have been provided, they do not
comply with the IRC standards. A simple audit has been done in one of the central parts of
Bangalore city to find out whether the road signs have been provided at the right place, and the road
markings done.
