3. Per testimony, Contractor drove over hubs, disturbed stakes, and then failed to resurvey prior to drilling piles.
4. Negligence: Contractor disturbed old surveyor hubs during construction and failed to timely or adequately resurvey building site in advance of pile drilling.
5. Negligence: Piles drilled and poured in wrong locations and out of plumb, compounding congestion problems that transferred up into building columns & walls
6. Gymnasium floor slab poured & finished out of specification tolerances by Contractor.
11. Contractor Progress Photos Depict Concealed Voids located by Contractor, hidden behind an Insulated Concrete Form Product
12. Contractor sack & patch in same location later discovered and examined during forensic Investigation
13. Contractor botched their secret repair undertaken without notice to Owner, Engineer or City Inspector
14. After discovering the true extent of their own defective work, the Prime and its Subcontractors failed to immediately stop work and notify the Owner, the Engineer of Record and the City as to their knowledge of various concealed job problems.
15. Forensic Analysis showed the Contractor had an isolated $150,000 problem and, by keeping a lid on it, turned it into a $2.5 Million disaster (inc. hard & soft repair costs, exclusive of 5 years of litigation costs, etc.), as their negligent methodology was then replicated again and again in pours throughout their after-progress on concrete construction.
16. Voids were found to be replete throughout the 3 Story, 22,000 sq. ft., structure designated A2.1 Public, with a max. 800 Person Occupancy, located in a Zone 4 Earthquake District.
20. Forensic Plan vs. As-Built & Progress Document analysis showed that Prime & Subcontractors knowingly encountered obvious, patent plan inconsistencies in the building dimensions, and failed to generate RFIs, choosing instead to proceed in error.
21. As-built dimensional bust -- Contractor mislocated piles/columns in relation to walls when laying out steel & pours, setting Columns 1” to 3” too far south.
22. Finding a Solution Maintaining Public Safety But Still Mitigating Client Costs The Good
23. Project Forensic Construction Superintendent commissioned an internal/external construction control survey & layout of the as-built construction
24. An elevation survey of the Gym Floor was commissioned to develop a remediation plan.
25. Ground Penetrating Radar & other methods were used in an attempt to locate hidden voids beneath the concrete surface.
30. Forensic Mock-ups show a sound mix & placement methodology could have been utilized by Contractor in this application, supporting the continued use of the ICF product.
