    We offer a comprehensive range of design and engineering services for the Oil and Gas industries. Tehran Raymand ensures the achievement of project goals and client satisfaction by employing a flexible, multidisciplinary engineering organization and task force teams. Our track record includes delivering 700,000 engineering man-hours annually, with a capacity to provide up to one million man-hours of engineering services per year. At Tehran Raymand, we foster a proactive engineering environment to meet design requirements and develop high-quality engineering solutions that consider all aspects of the project. Our engineering teams adhere to project contractual agreements and industry standards while employing best engineering practices. Additionally, Tehran Raymand's engineering departments offer technical support to the procurement organization by assisting in the selection of qualified bidders for materials and equipment purchases. They also provide technical support, whether at our home office or in the field, to resolve any technical queries that may arise during fabrication and construction activities. Throughout the engineering process, we ensure safety and constructability aspects of the plants are addressed through multidisciplinary meetings. To establish a uniform and agreed-upon foundation for our engineering methods, we have designed our engineering processes using process mapping techniques, aligning them with our business strategies, objectives, and plans.

  • Procurement

    One of the primary objectives of Tehran Raymand's Procurement Division is to acquire materials and equipment that are fit for their intended purpose and comply with quality and safety requirements. These procurement activities are carried out while considering the project's timeline to ensure that the necessary information is delivered to the engineering teams according to the schedule and that equipment and materials are available at the construction site as planned. All these activities are conducted with careful monitoring of the project's budget. For each project, a multidisciplinary and highly motivated procurement team will be assigned. This team, with the assistance of an integrated procurement management system, will oversee all stages of the procurement process, including requisition preparation, purchasing, transportation, and on-site delivery. Additionally, this procurement team, supported by Tehran Raymand's engineering departments, is responsible for verifying that the purchased equipment and materials comply with the relevant specifications.



  • Supply Chain Management

    Supply Chain Management has been a key component of Tehran Raymand Consulting Engineers' strategic objectives. We have implemented an assessment system to evaluate the performance of our manufacturing subcontractors, which includes stationary, rotating, and packaged equipment, electrical equipment, control and instrumentation, piping, and more. This assessment system is designed to establish a supply chain management network that delivers high-quality services across various projects. Tehran Raymand views this system as one of its competitive advantages, both in terms of cost and quality.


    The Tehran Raymand construction management team ensures that activities carried out on construction sites are coordinated and aligned with the project's predetermined goals and objectives. This team actively participates in construction and installation activities and collaborates with both the client and various construction contractors. One of the primary responsibilities of this team is to ensure that construction contractors meet all requirements and contractual obligations. Tehran Raymand's on-site organization closely collaborates with the client's site team and jointly conducts quality inspections, testing, and addresses any other potential aspects related to the project's main objectives. Our construction supervision teams oversee the project's quality, time, and cost objectives as outlined in the project plans. This includes monitoring construction progress to compare it against the project plan and propose corrective actions in case of any deviation from defined milestones and objectives. Ensuring the safety of both personnel and projects is one of our key priorities, and we achieve this by assigning HSE (Health, Safety, and Environment) teams who are consistently present at the sites to ensure the strict adherence to all safety regulations.

    To facilitate effective and efficient project management at Tehran Raymand, we have implemented an integrated project management system within our organization. Our professional resources, coupled with the utilization of the latest project management tools and methodologies, enable us to consistently progress toward the predetermined objectives of various projects. We employ a comprehensive management methodology that encompasses the entire project life cycle in all Tehran Raymand projects, ensuring their successful completion. This management philosophy takes into account the key project constraints, including schedule, cost, scope, and quality. To further enhance the application of this management philosophy in each project and reinforce our organizational standards and principles, Tehran Raymand has established a "Project Management Office (PMO)." This PMO serves to maximize the effectiveness of our designed management approach.
