Quality Control Fundamentals in Infrastructure Projects

What is the primary focus of Quality Control (QC) in construction projects?

• Planning project budgets

• Identifying defects in the final product

• Preventing defects through planning

• Designing construction layouts

Which phase involves final inspections and preparation of punch lists?

• Design Phase

• Construction Phase

• Pre-Construction

• Post-Construction

Why is materials testing critical in QC?

• It can replace the need for inspections

• It prevents contractors from cheating

• It provides definite evidence of material quality

• It helps make construction faster

What document from DPWH sets the national standards for QC?

• ISO Handbook

• DPWH Blue Book

• ASTM Manual

• Quality Control Logbook

Who is primarily responsible for supervising materials testing?

• Project Inspector

• Survey Team

• Materials Engineer

• Field Technician

Poor joint construction in concrete leads to:

• Better compaction

• Water ingress and cracking

• Cost savings

• Higher strength

What is a best practice during the material management phase?

• Skip laboratory verification

• Test only upon final delivery

• Pre-qualify materials and suppliers

• Use non-standard methods

What should be included in QC summary reports?

• Budget details

• Daily timesheets

• Test results and certifications

• Contractor’s personal notes

Which role collects field samples and performs on-site tests like the slump test?

• Laboratory Aide

• Resident Engineer

• Project Engineer

• Field Technician

Which team ensures all works are aligned per design and elevation during construction?

• Field Technicians

• Materials Engineers

• Survey Team

• Project Inspectors
