SHORT POINT FORM COVERAGE
• Project management = planning + contracts + cost + scheduling
• Surveying = layout + elevations + control points
• Earthwork = cut/fill + compaction + safety
• Roadwork = subgrade + asphalt + concrete + drainage
• Bridges = structures + foundations + reinforcement
• Materials = testing (concrete, asphalt, soil)
• Safety = OSHA + traffic control
• Equipment = selection + productivity
• Environment = erosion + compliance
• Inspection = QA/QC + documentation
