Dependency aware execution across services.

​

 

What This Is

Multi Trade Projects is the system that allows multiple trades to operate inside a single, shared execution model.

This is not bundling services.
It is not sequencing jobs manually.
It is not “project management” layered on top.

It is a dependency aware structure where every trade references the same property data, scope logic, timing assumptions, and constraints.

 

Why This Exists

Most failures in renovation and improvement work are not trade failures.

They are handoff failures.

One trade finishes late.
Another arrives early.
Materials are not ready.
Access conflicts occur.
Responsibility blurs.

When trades are planned independently, the system has no way to protect against cascade failure.

Multi Trade Projects exists to make interdependence explicit before work begins.

 

How Multi Trade Is Defined

All trades operate inside one project container.

The system establishes:

Which trades are involved
Where each trade applies spatially
What work depends on what
What must be completed before the next begins
Where overlap is allowed and where it is not

Trades are no longer blind to each other.

 

Dependency Mapping

Dependencies are not inferred in real time.

They are declared up front.

Examples include:

Demolition before framing
Framing before electrical
Electrical before drywall
Drywall before paint
Paint before flooring

These relationships are locked into the project, not left to interpretation.

 

Shared Measurement and Scope

All trades reference the same underlying measurements and spatial model.

This eliminates:

Conflicting dimensions
Overlapping assumptions
Redundant site visits
Scope disputes between providers

Each trade prices and executes against the same reality.

 

Scheduling Without Collision

Scheduling is derived from dependency, not availability alone.

One trade cannot be scheduled in isolation if it blocks or depends on another.

This prevents:

Crews arriving to unfinished work
Idle time on site
Compressed schedules that fail in practice

Time becomes coordinated, not optimistic.

 

Change Propagation

When one trade changes, the system understands the impact.

If scope expands
If timing shifts
If materials delay

The downstream effects are visible immediately.

Changes propagate structurally instead of surfacing as surprises.

 

Accountability Without a General Contractor

There is no single person “holding everything together.”

The system does that instead.

Each trade is accountable to:

Its defined scope
Its dependency position
Its documentation requirements

Coordination is enforced by structure, not heroics.

 

Why This Is Not a Marketplace Feature

Marketplaces connect trades.

They do not coordinate them.

Multi Trade Projects is one of the clearest lines between Cohos and every directory, lead platform, or bid board.

This is infrastructure behavior, not matching behavior.

 

Structural Role

Multi Trade Projects allow Cohos to handle complex work without becoming a general contractor.

Coordination lives in the system.
Risk is reduced through definition.
Execution scales without chaos.
