Gabri Siby

• Performed laboratory and field testing on concrete, soil, aggregates, steel, cement, and road materials in
compliance with IS standards, with working knowledge of equivalent ASTM and BS EN test methods.
• Prepared and validated 600+ detailed test reports with accurate calculations, maintaining zero compliance
failures across all submissions.
• Executed concrete mix trials and supervised cube casting, curing, and compressive strength testing at 3-day,
7-day, and 28-day intervals.
• Conducted soil compaction testing (Standard and Modified Proctor), field density testing (Sand Replacement
and Core Cutter methods), and CBR testing for foundation and pavement projects.
• Performed mechanical testing on reinforcement steel including tensile strength, yield stress, elongation, and
bend/rebend tests per IS standards.
• Carried out aggregate and road material testing for GSB and WMM layers: sieve analysis, AIV, ACV,
flakiness/elongation index, and soundness tests.
• Determined bitumen content in bituminous mix samples using extraction method to verify compliance with mix
design specifications.
• Conducted NDT testing including Rebound Hammer, UPV, and core compressive strength assessments to
evaluate in-situ structural integrity.
• Managed equipment calibration coordination with external agencies to maintain testing accuracy and ISO/IEC
17025 compliance.
• Liaised directly with clients on test requirements, sample submissions, and technical clarifications to ensure
timely project delivery.
• Assisted senior engineers in plate load tests, field investigations, and pile integrity assessments on large
infrastructure projects.
