Nagham Salman , Muna Hamadeh

The aim of the research is to shed light on the relationship between the concepts of Virtual design and construction (VDC) and building information modeling (BIM), and in particular to identify and evaluate the potential benefits of using a methodology based on the integration of the fourth dimension of (4D BIM) with virtual design and construction (VDC) and its impact on the preparation of the schedule and project planning and construction simulation. The research reviews a case study of "Pharmacists Syndicate building - Tartous branch", the building model (3D BIM) was created in Autodesk Revit 2020 ®, then the model clash was detected, reviewed and resolved, and the quantities were calculated on the Autodesk Navisworks Manage 2020 ® program, and the time periods for each activity were estimated according to the quantities, workshop performance rates and teams. Finally, time schedule was created in Bentley Synchro PRO 2020® software, the elements of the schedule was linked to the (3D BIM) model and the resources needed to implement each activity, then the construction simulation of the model was performed. The results showed the importance of (4D BIM) and the use of software in accurate modeling of all building elements and solving design problems before construction, which in turn has a significant impact on reducing time and cost of the project implementation. Model-based calculation of quantities helps to accurately estimate resources and times for activities. The importance of scheduling within a virtual environment based on the (3D BIM) model lies in the ability to digitally plan all aspects of a construction project, create and discuss different work sequences, in addition to managing cost, schedule, earned value, risk management, site integrity, logistical planning and mega-project management before and during implementation. However, we cannot only rely on software and technologies, but there must be an integrated methodology that organizes construction operations, and here comes the role of (VDC) Virtual design and construction as an innovative implementation strategy that adopts (BIM) building information modeling. As the success of any project depends greatly on the efficiency of the management and organization of its operations to achieve its desired goals.

Proposal for a Project Management Office "PMO" in the Public Establishment of Housing in Syria

Sosaina Alchoufi , Muhammad Shaaban

In today's rapidly changing world where change is the master of the situation, the rapid development of project management practices in the business world has become a necessity rather than an option. Organizations operate in a competitive environment and for this reason they look for what distinguishes them from their competitors, improves the success of projects, (PM offices or PMOs) gives this feature, hence, organizations have adopted PMOs in many industries including the construction industry. This study highlighted the importance of applying modern project management methodologies in Syria in order to keep pace with the global market, especially through adopting Project Management Offices (PMO) in its construction industry as (PMO) is the ideal approach in managing projects efficiently and successfully. The Public Establishment of Housing in Syria has been selected as a case study because of the importance of the housing sector in Syria, which was affected by the Syrian crisis and the recent earthquake, which led to an increase in the demand for housing. A framework has been proposed and developed for PMO implementation and operation in the Public Establishment of Housing in Syria. This proposed Project Management Office aims to improve the reality of its project management by ensuring that these projects are completed in a timely manner, within budget limits, and to the required quality standards. The methodology used in this research included two axes: the first is a study of the literature for a deep understanding of PMO, and the second is interviews with housing organization employees to identify current practices in project management in the organization and what problems they suffer from, and then suggest the appropriate type of project management office for it.

Rania Zakaria , Sonia Ahmad , Hamza Omran

Recently, AEC companies in Syria have realized the importance of adopting BIM in their system, especially in the next phase of reconstruction in Syria. However, due to the recent experience, the BIM process is still in its early stages and needs a lot of efforts to overcome the technical and administrative obstacles in front of it. The research methodology is based on analyzing models of organizational structures for AEC companies operating with BIM technology around the world, and studying their strengths and deficiencies in order to extract the most important factors for improving the performance of BIM in the Syrian construction industry companies. The study concluded with proposing a framework for the integration of BIM models in the structure of AEC companies, and companies that do not use BIM or that operate partially according to BIM can adopt it in developing their administrative structure in accordance with their own characteristics and the requirements of applying BIM in them.

Net-Zero Energy Building Using Solar Photovoltaic Energy and Modeling within BIM Environment: Case Study of Al-Ajraf Elementary School in Quneitra

Reema Mrad , Doha Jdeed , Sonia Ahmed

This research focuses on transforming Al-Ojraf Primary School in Quneitra Governorate into a zero-energy building by securing its energy source using a photovoltaic solar system. The Building Information Modeling (BIM) environment was utilized to create the necessary electrical plans and determine the available surface areas required for implementing this system. The existing electrical loads in the school (for lighting and fans) were initially calculated, followed by determining the suitable photovoltaic system to meet these loads, including the number of solar panels and the surface area needed for their installation. The calculated capacity of this system amounted to 12.510 kilowatts, composed of 12 solar panels, requiring an installation area of 32 square meters. The required capacity of the photovoltaic system was recalculated after replacing the school's electrical equipment with devices operating on direct current (DC), resulting in a system capacity of 7.260 kilowatts, providing a savings of 5.25 kilowatts, i.e., by 42%. The number of panels required to power the school's loads decreased to 6 panels, reducing the necessary installation area to 16 square meters, i.e., by 50%. This replacement also eliminated the need for batteries and expensive inverters, resulting in significant cost savings and a substantial reduction in electricity consumption from the main grid.In Sweida Governorate، there are a total of 253 elementary schools. If these schools were transformed into zero-energy buildings following the method outlined in this research, it would lead to a daily saving of 1328.25 kilowatts from the main grid.

Effects of Applying BIM on Facility Management for Existing Buildings

Rania Salman , Rana Maya

Building Information Modelling (BIM) is increasingly being used construction projects, and it demonstrates its ability to improve the construction industry's performance, However, its application in facility management still moderate and has not yet reached the potential and expected full use. The most common problem facing facility managers is the ability to access and manage the information. Information is the key to operate existing buildings and most importantly is the ability to collect, analyze, and handle it in an appropriate manner to be used for the facility management phase and the entire building life. However, there is insufficient understanding of the correct standards, processes and policies to be followed in the submission and management of such data, a significant lack of professionals and lack of knowledge of their software. This study aims to explore the value of BIM and the challenges affecting its application in FM, as well as address the information required for effective facilities management in existing buildings and the challenges to maintain a continuous update of BIM information in FM. The research methodology is based on analytical method: Using a questionnaire to a sample of staff and engineers in facilities management to detect the effects of applying BIM to facility management. The research demonstrated the importance of creating a BIM model for existing buildings and its effects to improve operations and maintenance, the need to increase BIM practices in engineering organizations. and indicated the most important benefits of the BIM for facility management application as: increase the efficiency of operation and maintenance staff's access to data, improve future operation design and preventive maintenance, facilitate decision-making throughout the operation and maintenance phase, and finally reduce costs and time while increase the quality of procedures.
