Architectural design (phase zero, phase one and phase two)
To carry out an architectural project, steps must be taken in order that before starting each of the architectural design steps, the next step must be passed in the best way and method and without any defects. All architectural projects for design are divided into three parts. The main ones are formed. These three parts (phases) must be placed regularly and continuously one after the other and behind each other in order to implement the desired architectural design as standard. The architecture or the lack of proper connection between them will fail the whole project architectural design set.
Zero phase design of architecture or architectural studies
In phase Zero, knowledge about the region and items such as the climate of the region, the architectural conditions of the region, rules and regulations, frameworks and standards, as well as a detailed study of soil engineering issues such as soil testing and are considered.
Phase zero of architecture is the stage in which the desired information is obtained and the process of recognizing and identifying the project is studied.
In the zero phase of architecture, the project is examined in terms of technical and economic justification as well as social justification of the architectural project. The desired information and knowledge in the zero phase of architecture is obtained in many cases through negotiations with the employer and awareness of the desired needs of the employer.
Phase design of an architecture
In phase one of architecture or architectural design, all the information obtained is implemented in phase zero and is named phase one in the form of architectural plans and preliminary architectural plans. in this section, if there is a need for revisions related to the initial design of architecture and plans, this important thing will be done.
In fact, designing a phase of an architecture is the interface between architectural studies and final architectural plans and the implementation of an architectural project. Therefore, it is very important to be careful in the first phase of an architecture and to hold meetings and exchange opinions and information.
Phase two architectural design
In the second phase of architecture, the architectural plans designed in the first phase of the architecture, since they do not have the necessary accuracy and sensitivity to carry out the construction project and are designed only to exchange ideas and opinions of different people, will be redesigned in accordance with national building regulations.
In phase two of the architecture, the final designed plans in accordance with the national building regulations will be presented to the contractor as the final project plans for the construction of the building.
Compliance of phase two architectural plans with structural plans (structural design) and facility plans (facility design) are the requirements of phase two architecture so that after the approval of phase one architecture, plans designed by the architect in phase two architecture in accordance with National building regulations are designed.
We, Marab Mahbod company are fully prepared to provide the three main architectural phases in full coordination with national building regulations.
