Pirraz consulting planners, architects and engineers was founded in 1983 by some of the ex-Bonyan consultant (est. 1960) senior partners, associate partners, and staff whose firm had to be dissolved due to new regulations concerning consulting firms in Iran.

During the past few years, Pirraz consulting has rapidly developed to rank among the efficient and prominent Iranian consulting firms and is still expanding.

The practice has been structured to provide comprehensive architectural, urban design and engineering services.

The practice offers, at the outset of any project, assistance in the selection and viability of a site and with the development of the project brief. In the case of a development site, feasibility studies are commenced to ascertain the projects' financial viability in terms of building space related to cost and return on investment.

At this stage, the architectural concept design commences. The Pirraz design team and partners work together to evolve the design concept. The collective experience and interaction of the team approach becomes a catalyst for an innovation design process. During this process, constant meetings are held with the Client so that through his continuous involvement his requirements and contributions can be incorporated into the development of the design.

The partners continue to participate with the project managers and senior staff in the preparation of clear, concise working drawings, specifications and the various contract and construction documents.

The quality and monitoring of the workmanship is the major responsibility of the firm's contracts. The partners and staff are all qualified through extensive experience in the construction field to administer and inspect the construction process. They interpret the construction documents realistically, maintaining a professional and fair relationship between all parties to the contract ensuring an efficiently managed project, and one of which is completed in accordance with the intent of the design and construction documents.
