Bidding on a single-family home is about precision and detail. Bidding on a 50-unit apartment complex is about scale and repetition. While multi-family projects offer the allure of consistent work for months, they are also where many contractors lose their shirts due to 'compounding errors.'
The Power of the Unit Cost
In multi-family bidding, your unit cost is everything. A $50 mistake in your kitchen cabinet estimate doesn't matter much on one house. But multiply that by 100 units, and you've just handed back $5,000 of your profit. You must nail the cost of a 'typical' unit before you even look at the common areas.
Accounting for Logistical Drag
One of the most common mistakes in multi-family bidding is assuming your crew will move as fast on unit #40 as they did on unit #1. Material staging, elevator wait times, and coordination with other trades create 'logistical drag.' Your bid must include a buffer for the time lost moving between floors and managing large-scale deliveries.
Standardization is Your Friend
Profit in multi-family comes from speed through repetition. Push for standardized fixtures and materials across as many units as possible. The fewer variations your crew has to handle, the faster they will work and the fewer mistakes they will make.
Key Takeaways
- Unit Precision: Verify your single-unit costs multiple times; errors compound fast.
- Logistics Buffer: Add 10-15% to labor for large-scale site coordination and material movement.
- Volume Discounts: Use the project's scale to negotiate better rates with your suppliers.
- Change Order Rigor: Multi-family developers will push for scope creep; document every change.
