Abstract
Sustainable Construction (SC) is considerably new trend particularly in developing
countries such as Egypt. So, applying Project Management (PM) to that new trend of
construction requires the relevant stakeholders to consider the sustainability principles
in implementing PM at the early phases of the project. This promotes for significant
cost savings over time, and a unique marketing strategy. For construction projects,
Feasibility Stage (FS) is the first and most important stage before undertaking project
design & construction .Its effectiveness will affect directly the success of the project.
A vast literature review revealed a number of essential elements (Enablers) and
assessment attributes (Drivers) that should be considered, as well as a number of
challenges that should be mitigated to integrate the principles of sustainability and PM
in the construction project. Hence, to investigate the current status for managing FS
of SC projects in Egypt and explore the benefits and barriers of integrating the SC
principles during FS; the survey research method has been adopted and data were
collected using designed structure questionnaire. The survey analysis has validated
the importance of both of the suggested elements and the assessment attributes for
managing the FS of SC project. Moreover, it is found that both of them have a
significant correlation with the most of categories of Green Pyramid Rating System
(GPRS) , which make them a helpful tool for awarding more credits of GPRS and
consequently achieving more SC project. Additionally, based on the real practice of
assessment attributes in Egypt (according to survey analysis); the Relative Importance
Index (RII) is calculated for each attribute, and then consequently the relative weight
for each attribute is estimated. Moreover, the analysis has explored that the most
applied Green Rating System (GRS) in Egypt is the US Leadership in Energy and
Environmental Design (LEED) more than GPRS , which is still less widespread in
Egypt.
Relying on both of the theoretical and field study, this research has developed a
model for Managing the Feasibility stage of Sustainable Construction Project
(MFSCP). The suggested model is built on five components: 1) Enablers, 2) Drivers,
3) Limitation, 4) Processes Flow chart, and 5) Model outcomes. Where, the Enablers
enable project stakeholders to be on track for achieving SC project by responding to
the acceptance limits of drivers which are represented by assessment attributes. This
model is working as a management and assessment tool, where it manages the FS
through five phases: 1) Initiation, 2) Initial conceptual integrated design, 3)
Procurement strategy, 4) Integrated sustainability plan, and 5) Preparing feasibility
report. These phases with related processes are represented by sequential processes
flow chart seeking for achieving SC within model restrictions.

The developed model is computerized using SQL server, and Visual studio C#
language; to be easy applicable. Where, it allows successive procedures, fast and
accurate calculations, as well as documents the processes with taken decisions.
MFSCP program is designed to be used by project consultant/ owner to come out by
the following results: 1)Assigning the roles and responsibilities of project
stakeholders, 2) Expected GPRS credits with related cost, 3) Estimated total cost and
duration of project during FS, 4) Present value calculations for economic indicators
(Net present value, Benefit / Cost ratio, and Payback period), 5) Assessment of project
alternatives using Value Engineering (VE) approach for selecting the most sustainable
one, and 6) selection of the most sustainable alternatives that has the highest total
score.
An actual case study (residential compound in Egypt) is used to validate the
applicability of the developed model. It is found that using MFSCP program is
applicable and would help project developers to reduce the extra time and cost due to
change orders for later project stages. Also, it is found that the phase of initial
conceptual integrated design during FS needs more effort than traditional project ,
which resulted in that more effort during FS saves more money during later project
stages.
This study has concluded that the developed MFSCP model can achieve Added
value; represented as it archives the input and output data to be retrieved for selected
project at any time. Also, it provides the weights for sustainability attributes for
alternatives assessment based on both of the theoretical study and real practice in
Egypt. Where, it applied the VE approach for selecting the most sustainable
alternative. Also, it saves the time and experience for required calculations during
project life cycle for GPRS , economic indicators and alternatives assessment.
Moreover, it calculates the duration and cost of feasibility stage through sequenced
processes which is linked with the GPRS credits and early assigned responsibilities of
project stakeholders.
Therefore, the main conclusions of this study can be summarized as following:
1. MFSCP model provides a good base for projects that seek green accreditation to
comply with Egyptian Green Pyramid Rating System (GPRS), and provides
channels for overcoming the challenges of achieving SC project starting by FS.
Consequently, the proposed model works as a kick of for managing SC projects in
its coming phases, where it works as management and assessment tool during FS.
2. The developed MFSCP model is programmed to be easy applicable, where it
allows successive procedures, fast and accurate calculations, and documents the
processes with taken decisions
3. GRS/GPRS cannot work alone for achieving SC project; where it doesn’t assess
social and economic aspects, and it doesn’t have a management system to be.
