    Study Notes

    Variation Orders and Extensions

    • Variation Orders include change orders, extra work orders, and supplemental agreements; resume orders are not included.
    • A project may receive a time extension if delays stem from reasons beyond the contractor's control, affecting critical activities.

    Retention and Payments

    • Upon satisfactory progress at 50% completion, no extra retention is imposed; a typical retention rate is 5%.
    • General items payment typically withhold up to 20% until final project acceptance.

    Material Specifications and Quality Control

    • Permitted variation for aggregate base course thickness is ± 20 mm; subbase course thickness variation is ± 10 mm.
    • Trial section area needed for material and method testing is about 400 sq.m.

    Mixture Proportions

    • The acceptable cement mix for Portland cement stabilized road mixes is 4 to 20 mass percent.
    • Lime stabilization for road mixes accepts a lime proportion of 2 to 10 mass percent.

    Soil and Base Conditions

    • Sub-grade soil must be well compacted at optimum moisture and maximum dry density for quality control.
    • Concrete procedures dictate base moistening for at least 6 hours before placing concrete.

    Project Management and Reporting

    • Defective works are reported to the contractor through an inspection report.
    • The logbook does not include survey data but documents daily activities, weather conditions, and material usage.

    Construction Safety and Delays

    • Construction safety procedures involve proper shoring of excavations and guarding openings; logging by equipment operators is essential.
    • Causes of delays include plan revisions and inadequacies in contractor resources; natural factors like predetermined rainy seasons do not count.

    Planning Tools and Maintenance

    • Bar charts are synonymous with Gantt charts, vital for project scheduling.
    • Repainting of a steel bridge is categorized as periodic maintenance.

    Concrete Handling Regulations

    • Concrete must be mixed and placed within 90 minutes of initial mixing; transport time from addition of water to placement should not exceed 30 minutes.
    • Waterproofing materials for fresh concrete include burlap or plastic sheeting, while metal forms may not be suitable.

    Piles, Tack and Temperature Considerations

    • Minimum penetration for piles in firm material is 4.0 meters; tack coat conditions should be sticky before applying the next course.
    • The minimum temperature for bituminous material application is 10 ºC.

    Inspections, Reports, and Allowances

    • Post-final inspection, certificates of completion are contingent on conducting an exit conference.
    • Essential items in inspection reports include recommendations for actions rather than team member details.

    Price Adjustment and Flood Mitigation

    • Contract price escalation is generally computed from the effectivity date of the contract.
    • Flood damage mitigation strategies encompass reservoir flow reduction and floodplain management, while highway drainage does not qualify as a mitigation measure.
