Selected work
Engineering is not the production of documents. It is the disciplined management of uncertainty—from source data and calculation to inspection, release and long-term performance.
Case studies
These summaries explain the engineering problem, method and professional judgement. Confidential calculations, drawings, names and commercial information remain outside the public archive.
Publication note: Project material is intentionally presented at a high level. Inclusion describes personal technical involvement and does not imply client endorsement or permission to redistribute controlled documents.
A coordinated ductwork delivery package for a live catering facility in Riyadh: scope definition, duct schedule, material data, fabrication and installation methodology, inspection and test planning, risk controls, checklists and testing interfaces.
A calculation-grade screening separating ultimate capacity under circular wheel, jack and pad footprints from fatigue under repeated axle loading. Boussinesq stress distribution and conservative CBR-based bearing were paired with AASHTO-1993 screening.
A complete quality-control method for batch-plant operations: stockpile separation, cold-feed control, aggregate drying, screening and hot-bin management, calibrated weighing, mixing, temperature control, sampling, testing and dispatch traceability.
A field-ready method covering surface acceptance, setting out, preheating, material application, glass-bead distribution, thickness and retroreflectivity control, traffic management, inspection and handover.
A decision pathway for excessive fines, unsuitable gradation and unverified plasticity: prioritising controlled blending where technically viable, with screening or washing reserved for deficiencies that blending cannot correct.
A developing research programme on public-infrastructure procurement in Saudi Arabia: moving beyond lowest price towards lifecycle cost, technical quality, contractor capability, sustainability and measurable long-term value.
Method
The same four gates recur across disciplines. Each prevents confidence from outrunning evidence.
Separate fixed inputs, assumptions, omissions, interfaces and acceptance criteria before calculation or execution begins.
Test source documents, material properties, dimensions, calibration status and applicable standards.
Convert the approved method into hold points, inspections, records, responsibilities and traceable release.
Capture deviations, performance evidence and close-out data so the next system begins from knowledge rather than memory.
Research in development
The procurement study examines why aggressive low-bid awards can produce delayed works, contractor distress, quality loss and expensive rework. Its proposed direction combines case evidence, stakeholder interviews and international best-value models.
Technical discussion
For engineering collaboration, research discussion or a technically serious review, begin with the objective and the source material.
