Ignoring the "Deviation from Specifications" Clause Section 105.4 states that no deviation is allowed without written approval from the DPWH District Engineer. Many contractors use "industry standard" mixes without checking if they match the 2019 PDF's exact Job Mix Formula (JMF) requirements. 2. Misreading the Tolerances Item 405 allows a "minus" tolerance for concrete cover, but not a "plus" if it causes honeycombing. The PDF explicitly states: "No reinforcement shall have less cover than specified." 3. Using Obsolete ASTM Standards Item 311 (Bituminous Seal Coat) in the 2004 edition referenced ASTM D946 (old penetration grading). The 2019 edition shifts to Performance Grade (PG) binders via ASTM D6373. Using the old spec will cause immediate project rejection. Why You Cannot Ignore Volume 3 in 2025 Filipino infrastructure is under intense scrutiny. Recent collapses of retaining walls and premature road deterioration have led to a crackdown by the DPWH and the Office of the Ombudsman. Prosecutors now specifically cite violations of the Blue Book Volume 3 as evidence of "Gross Negligence."
