Hire the Best RSpec Specialists
in Egypt

High-stakes, mega-project experience isn't learned in a classroom—it’s forged in the field. I am Ahmed, a Senior Planning Engineer with 6 years of experience managing project controls for some of the most demanding construction environments in the world. From the skyline-defining mega-projects of New Alamein with CSCEC to high-spec Oil & Gas infrastructure for Saudi Aramco (MSSD), I specialize in keeping multi-billion dollar timelines under control. Why am I different: I don’t just manage schedules; I manage risk. My background with Aramco as an owner and CSCEC as a General Contractor gives me a 360-degree view of project delivery. I know exactly what owners require for compliance and what subcontractors need for execution. My Specialized Expertise: Mega-Project Scheduling: Expert-level Primavera P6 management for large-scale developments, including complex WBS structures, thousands of activities, and multi-tier logic ties. Aramco Standards & Oil & Gas: Deep understanding of Aramco’s planning requirements, including progress measurement systems, resource histograms, and rigorous reporting cycles (MSSD project experience). Forensic Delay Analysis: I don't just identify delays; I solve them. I use AACE methodologies to perform Time Impact Analysis (TIA), identify the root cause of 30+ day delays, and build realistic Recovery Plans that stakeholders actually trust. Integrated BIM Controls: I bridge the gap between the model and the schedule, using tools like Revit and Solibri to ensure quantity take-offs and resource loading are 100% accurate. Technical Toolkit: Software: Primavera P6 (Advanced), MS Project, Revit 2025, Solibri, Procore, and Excel (Advanced Macro/VBA reporting). Core Skills: Critical Path Method (CPM), Earned Value Management (EVM), Cash Flow Forecasting, S-Curves, and AI-enhanced Project Controls. Certifications: PMP preparation. The Result: When you hire me, you aren't just getting a "scheduler." You are getting a Project Controls Partner who understands how to navigate the pressure of international standards and mega-project complexity. I build the systems that protect your profit margins and defend your timeline. Let’s discuss your project goals. I am ready to review your current schedule and provide a professional assessment to ensure your project stays on the critical path.
