| 1 | Preconstruction and Permits | Kickoff, drawings, permit plan, inspection plan, baseline schedule | The schedule should not start with site work until drawings, permit assumptions, and inspection hold points are clear. | 7-20 days |
| 2 | Procurement and Mobilization | Long-lead procurement, subcontractor release, site mobilization | Materials, crews, temporary utilities, and site access determine whether the early construction sequence can actually start. | 10-25 days |
| 3 | Site Preparation | Survey, temporary facilities, clearing, earthwork, excavation | Site control, access, and earthwork prepare the workface for foundations and underground services. | 10-25 days |
| 4 | Substructure | Ground improvement, foundations, underground services, curing | Foundations and underground services are high-impact dependencies for structure, envelope, and external works. | 20-35 days |
| 5 | Superstructure | Frame, slabs, stairs, shafts, core, roof structure | The building frame creates access and constraints for envelope, MEP rough-in, and interior trades. | 25-45 days |
| 6 | Building Envelope | Exterior walls, roofing, waterproofing, windows, exterior doors | Weather protection controls when interior work, finishes, and sensitive equipment installation can proceed reliably. | 20-35 days |
| 7 | MEP Rough-in | Mechanical, plumbing, electrical, fire protection, sleeves, equipment rough-in | MEP rough-in must be coordinated before drywall, ceilings, finishes, system testing, and authority inspections. | 20-40 days |
| 8 | Interior Works | Insulation, drywall, ceilings, flooring, painting, fixtures, hardware | Interior trades should follow weather protection and rough-in completion so rework and access conflicts are reduced. | 25-45 days |
| 9 | External Works | Drainage, paving, utilities tie-in, landscaping, site cleanup | External work affects access, final inspections, occupancy readiness, and client handover. | 15-30 days |
| 10 | Testing and Inspections | MEP testing, fire alarm test, life safety inspection, authority inspection | Testing and inspections convert the physical work into an accepted, usable building or project area. | 10-20 days |
| 11 | Handover and Closeout | Punch list, as-built documents, O&M manuals, training, final clean, handover | Closeout tasks protect the final delivery date and keep documentation, training, acceptance, and turnover visible. | 7-20 days |
