Engineering and Desing
DESIGN AND SURVEY WORKS PROCEDURES:
PBi teams, in different aspects of engineering process embrace valuable expertise and modern knowledge to carry out multi-disciplinary projects. We start with conducting survey and assessment; the assessment team evaluates project location, resources availability, security conditions, natural impacts and other information into the project evaluation process, this helps the decision makers in selecting better choices and to provide better solutions to the project. The survey team follows to find position of the project site by using GPS with having the Global Coordinates in hand, alternatively, local Bench Mark Coordinates would be used in case the global coordinates are not available.
Our surveyors use modern surveying tools like Total station to collect the data from the project site, by using computer-aided application, the data is transferred to AutoCAD and Civil 3D, The Civil 3D application automatically generates contour lines and topographic plans, surveyors provide exact and detailed topographic plans for other disciplines in the design team.
Civil 3D program is used to provide calculations and other data in an automatically manner, quick design information for master planning and civil design is provided in matter of minutes.
Grading plan and site layout plans are designed for laying out the buildings and utilities. Grading and Sloping of the project site in coordination with water supply and drainage systems, are also carried out by designers and the site plan architects.
The Master plan is developed by expert architects, water supply engineers, mechanical engineers and road\bridge designers under the technical supervision of a senior civil engineer acting as team leader. The concept of a master plan is divided into architectural, civil, mechanical, electrical, water and sewer plans, the detailed structural design is carried out by a team of experienced structural designers. Architects often act as design manager to coordinate various technical issues among different disciplines.
Design project manager in collaboration and consultation with other members of the team; initiates the architectural design by observing the technical points of view of other discipline designers. Structural engineer in addition to the structural design; collaborates with architect to initially design an efficient structural system for the buildings.
The design documents we provide for a project are comprised of both drawings and analysis. Specifications, Bill of quantities, construction methodology\solutions are also provided in the design package. Documents are printed and packed in a standard way to be easily used by Engineers.

PBi is specialized in professional surveying using the most updated instruments in this field. Our experience enable us to perform large projects with expedited schedules at reasonable costs.
Our initial goal in providing architectural services to our clients is creating design excellence within the project scope and budget. PBi Architectural Group works to identify project parameters, set priorities, and establish the goals. We also help our clients to predict future needs and incorporate these into our design solutions. To achieve these goals, PBi assembles a team of professionals to the specific needs of each project. For each assignment, PBi considers the project in its entirety, within the boundaries specified by the client, and with the comprehensive expertise of PBi staff. The result is a balance between the theory and the practice, and the creative and functional. Most important is PBi‘s commitment to achieving a cost-effective design that meets today’s standards and to predict the needs of tomorrow. We believe that it is the creative ability that enables us to look beyond established practices to find new and better solutions. This might involve developing an innovative approach to project funding, or apply creative new techniques to solve recurring challenges. It might mean looking beyond the scope of the project to make recommendations for more efficient and cost-effective solutions. The result is a balance between the aesthetic and the practical, and the creative and the functional.

PBi design team has been building architectural models for years; our modeling team is composed of experienced model makers, graphic designers and collaborating architects combining traditional craftsmanship with the latest technologies. PBi is thoroughly committed to producing quality models and computer images to give our clients the best visual presentation of their architectural projects.
PBi architects use molding as an efficient method of understanding and controlling the effects produced by the design, the models produced by our model makers signify an essential presentation for houses, apartments, tourist complexes, hospitals, airports, seaports and any other construction facility which need to be understood visually. However, there is a general belief that, with the development of computers and 3-dimensional on-screen presentations, scale models are a thing of the past but, PBi Model makers use 3D printers operated by skilled technicians which produce 3-dimensional objects by combining latest modeling technology with traditional hand modeling techniques to achieve high quality scale models, it is worth to mention that the objects produced by 3D printers still needs hand finishing.
The landscape is to lead the allied design and planning fields towards helping to create a future that is sustainable and enhances the quality of life. We believe this requires the ability and ambition to re-design the city, by this, we mean that towns or urbanizing environments can be (re)designed to support the health and well-being of human beings and other species. The landscape can make an essential contribution to understanding and addressing the cumulative impacts of people on sites, of sites on landscapes, and of landscapes on people and natural systems. Landscaping adds marketability and long-term value to real-estate. It creates aesthetically pleasing open spaces for recreational activities which can hide unattractive views, create a comfortable retreat, and dress up an otherwise “Ordinary” building.
Before beginning the design process, our landscape architects consider budget and time constraints, the needs of those who are using and maintaining the project site, and its soil, vegetation, wildlife, climate, social, historical, and cultural characteristics. Finding a solution to a problem dictates that each project be seen as unique effort, This fact challenges the designers to apply knowledge from prior experience, yet to view each endeavor as an original. Successful design grows from this knowledge, which is attained through looking, listening, and testing many ideas. We believe that the quality of the place is fundamental to the quality of life.

The projects we have completed collect and disposes household wastewater generated from toilet, bathing, laundry, kitchen and cleaning activities. These facilities with running water, such as house or office, have been connected to one of the following wastewater disposal systems:
Centralized systems were public sewer systems that served established towns and cities and transport wastewater to a central location for treatment.
Where appropriate, centralized systems were preferred to decentralized systems, as one centralized system can server in lieu of several decentralized systems. Centralized systems are more economical, which allow for greater control, require fewer people, and produce only one discharge to monitor instead of several. However, decentralized systems can be useful, and this option was evaluated on a case-by-case basis.
In decentralized WCTS wastewater was treated on site and was discharged to a private treatment plant.
Homes and other buildings that were not served by public sewer systems depended on decentralized septic systems to treat and dispose of wastewater. Wastewater in decentralized systems can be treated by a small, private wastewater treatment plant. These plants have similar treatment processes and equipment as centralized systems but on a smaller scale.
