Key Differences from Vertical Construction
| Aspect | Heavy Civil | Vertical Construction |
|---|
| Owner | Public agencies (DOT, authorities) | Private, developers |
| Procurement | Public bidding, low bid common | Negotiated, GMP common |
| Contract Type | Unit price typical | Lump sum typical |
| Specifications | DOT standard specs | CSI MasterFormat |
| Inspection | Agency resident engineers | Third-party or owner |
| Payment | Monthly estimates, retainage | AIA G702/G703 |
| Change Orders | Contract modification, differing conditions | CCD, PCO process |
| Schedule Impacts | Weather days, utility delays | Owner delays, RFIs |
| Bonding | 100% P&P bonds required | Often waived for large contractors |
| Safety | Work zone, MOT, public interface | Site-based, enclosed |
