This document discusses an evaluation study of lightweight building systems based on value engineering theories. It provides definitions and classifications of different lightweight building systems like drywall, custom walls, polystyrene walls, metal sheet walls, modular buildings, and precast walls. It also discusses the methodology, philosophy and quality module diagram of value engineering. Finally, it summarizes four case studies where different lightweight building solutions were used, including Kidzania in Cairo Festival City, a private villa extension in Cairo, a seasonal flights terminal at Cairo Airport, and a resort in Libya.

Fused deposition modelling (FDM) has become a prevalent technique to additively manufacture polymer that can provide design freedom and creativity. However, like any other AM technologies, FDM has its own challenges. The inherent void, surface roughness and dimensional accuracy during manufacturing can lead to tolerance rejection, cracking or failure during the product life. Also, the resultant anisotropic material properties are inherent in the layer-by-layer manufacturing features. Therefore, it is important to understand and simulate FDM process, in which complex thermo-mechanical interaction takes place due to rapid heating/cooling.
The current work will first provide a brief overview of the current polymer AM simulation solutions, validation protocols, and standardization efforts. Secondly, a simulation framework using Abaqus will be presented to replicate the FDM process that can provide insight into how the process parameters affect product quality. Currently, simulation solutions has the capability to model the polymer extrusion process with that can capture the layer-by-layer element activation feature and varying free surface in heating and cooling. Finally, an example study will be presented to show how modifying process parameters such as raster angle, contour width and layer thickness affect the transient thermal, deformation and residual stress field. Accordingly, optimal processing parameters can be identified based on the criterion of minimizing distortion and residual stresses.
According to the Construction Industry Institute, modularization entails the large-scale transfer of stick-build construction effort from the jobsite to one or more local or distant fabrication shops/yards in order to exploit one or more strategic advantages. Nonetheless, the majority of projects today still do not exploit these strategic advantages to their fullest potential.
Modular Construction has many advantages over conventional stick-build construction. These benefits include shorter schedules, lower cost overall cost, minimal plant site interruption and many more. Strengthen your knowledge of when and why to choose modularization as a project delivery model.

Research Idea
During the last couple of years, the obstacles of the traditional methods of
construction have tremendously increased along with the development of the
construction demand. Eighty percent of the total buildings in the developed
countries have been produced in the construction factories, comparing with
twenty percent of buildings that constructed on-site. Weight, quality, speed and
construction cost become the major factors that affect in the architectural and civil
decisions.#Ref13
On the other hand, the construction industry becomes one of the main influencers
of the international economics, therefore the reduction of construction cost and
energy cost are considered as main targets that attacking the decision makers.
Hence, the idea of research has been created, in order to present a solution for
architects who target the maximum performance of the lightweight building
solutions with a reasonable level of cost. The practical studies of research
presented the benefits behind using the Value Engineering theories throughout the
construction phases.

sheets of paper. It is used to make interior walls and ceilings. Drywall
construction became prevalent as a speedier alternative to traditional lath
and plaster. A wallboard panel is made of a paper liner wrapped around an
inner core made primarily from gypsum board.

9. Modular construction is a process in which a building is constructed
off-site, under controlled plant conditions, using the same materials and
designing to the same codes and standards as conventionally built
facilities – but in about half the time. Buildings are produced in
“modules” that when put together on site, reflect the identical design
intent and specifications of the most sophisticated site-built facility –
without compromise.

10. Precast concrete is a construction product produced by casting
concrete in a reusable mold or "form" which is then cured in a
controlled environment, transported to the construction site and lifted
into place. In contrast, standard concrete is poured into site-specific
forms and cured on site. Precast stone is distinguished from precast
concrete by using a fine aggregate in the mixture, so the final product
approaches the appearance of naturally occurring rock or stone.

Quality model is the entry point
during the planning phase for
establishing and developing the
owners' project criteria.
The quality model (QM )provides
a thorough definition of project
performance expectations required
by the owner. The approach of QM
is based on the total quality

The own weight of building material is considered as a main criteria that
classifies the construction systems through heavy weight solutions or lightweight
solutions, either it is a load-bearing or non-load bearing element. Hence, six
lightweight building systems have been selected to be studied during the
research, the average weight of systems started from 25kg/m2 for Drywall
systems, 30kg/m2 for Custom-made walls, 33kg/m2 for Polystyrene walls,
35kg/m2 for Metal Sheet walls, 45kg/m2 for Modular buildings and finally
70kg/m2for the precast walls that have been developed by decreasing the own
weight per meter square from 110kg/m2 to 70kg/m2.

Conclusion
Introduction Systems V Engineering Studies Conclusion
Value engineering consists of some theories that help the decision makers to
take the right decision that reflects in the technical performance as well as the
cost performance. The main target of value engineering is keeping the projects
in the best quality module that evaluates the architectural image, engineering
performance, operation time and resources.
There is a deep relation between the lightweight building solutions and the
industrial development. The off-site technique of construction increases the
ability of using the lightweight building solutions which need an industrial aiding
before starting the on-site construction.
Sound insulation, heat transfer, energy consumption, fire resistant and
durability are considered as main criteria of building performance that can be
accurately accounted in the lightweight building systems, comparing with the
performance of the traditional method of construction that are not giving
accurate performance according to the international codes and the local norms.
