Study Notes
Construction Management and Engineering Concepts
- Non-availability of construction materials can hinder project timelines.
- Rainy months may be predetermined in specific areas, impacting construction schedules.
Project Management Tools
- Bar charts are often known as Gantt charts, useful for project scheduling.
Project Supervision
- The Project engineer oversees the project, supported by the resident engineer during field operations.
Financial Management in Projects
- Retention rate for progress payments should be 5% if work is 50% complete and satisfactory.
- A time extension due to delays beyond contractor control is granted if the works are identified as critical activities.
Variation Orders
- A variation order does not include resume orders; it can be in the form of change orders or extra work orders, with a maximum allowable percentage for change orders at 10%.
Engineering Judgment and Project Implementation
- The resident engineer's judgment prevails in field implementation decisions.
Vertical Datum
- Mean sea level is the single vertical datum used for infrastructure projects' elevation references.
Supervision and Standards
- Project inspectors supervise work and tests during project implementation, ensuring compliance with standards.
- Minimum field density for embankment materials is set at 95%.
Soil and Material Testing
- Non-plastic soil (item 200) allows for the liquid limit and plastic limit tests.
- Measurement of concrete materials for structures is based on weight.
Foundation Types
- When suitable soil is found within 2-3 m below riverbed, spread or raft foundations may be used.
Project Documentation
- A logbook compiles project data from start to completion, documenting activities, materials used, and weather conditions.
Hydraulic Structures
- In riprapping, weep holes provide water outlet and relieve lateral pressure on structures.
Pavement Rehabilitation
- Overlaying strengthens existing asphalt or concrete pavement by adding adequate thickness.
Load and Design Analysis
- The maximum impact applied to bridge superstructures is calculated using the formula: 15.24/(L+38).
Construction Elements
- Gravity loads include permanent components, but wind load is not classified under this category.
Lateral Force Analysis
- Lateral forces in building frames can be analyzed using the Moment-Distribution Method, Portal Method, Factor Method, or Cantilever Method.
Project Delays
- Contractors may claim for price adjustments if projects start over 8 months after bidding.
Final Inspections
- Exit conferences are conducted before issuing the final inspection certificate for completed projects.
Inspection Reports
- Recommendations for action by inspectors are crucial items in inspection reports.
Curing and Strength of Concrete
- Recommended curing temperature for concrete is between 15-18°C with a minimum flexural strength requirement of 3500 psi for Portland Cement Concrete Pavement.
Soil Classification and Testing
- Soil classification can be determined through Atterberg limits and sieve analysis tests.
Asphalt Pavement Criteria
- For asphalt pavement projects, ensure drainage facilities are maintained, and avoid flood-prone areas.
Sampling and Testing
- Core sample measurement for asphalt pavement should take at least 3 readings for thickness determination.
Temperature Tolerances
- The required mix tolerance for bituminous temperature is +/- 10°C.
Quality Control
- Prime coat application requires a minimum undisturbed period of 24 hours for proper bonding.
