Five stages.
One project manager.

Every CS1 project moves through the same five gates. Each stage closes with a written sign-off — so nothing moves to construction without you knowing exactly what will be built, when, and for how much.

01

Discovery & Assessment

On-site property assessment, scope alignment, unit walks and condition reporting. Two weeks. Refundable feasibility deposit.

02

Scope & Material Selection

Detailed scope of work, finish schedules, vendor coordination. Fixed-price proposal at end of stage.

03

Pre-Construction

Permits, structural engineering, material lead times locked. Trade walkthrough with your project manager.

04

Clean-Site Construction

Daily cleanup, daily photo report, single point of contact. Coordinated around tenant schedules and property operations.

05

Final Walkthrough & Closeout

Final walkthrough, punch list closed inside 14 days, project documentation and materials delivered.

Proven at scale.

Six commitments.
Signed and dated.
Every project.

We hand you this document — printed, signed by the project manager — on the day construction begins. If we miss one, the remediation is on us, not on the change order.

01

Respect for your property and tenants

Coordinated around tenant schedules, dust barriers, clean work zones. Minimal disruption to property operations.

02

Transparent pricing, no surprises

Fixed-price contract signed before demolition. Any change requires your written approval first.

03

Daily cleanup, documented

Site swept and photographed at the end of every workday. Photos emailed to you before 6 PM.

04

Licensed craftsmen, trained crews

Every carpenter, electrician and technician on your job is background-checked and insured. Consistent teams across your portfolio.

05

One project manager, start to finish

The PM who signs the contract is the PM who hands you the keys. No handoffs, no telephone, no excuses.

06

Scalable execution, consistent quality

From 10 units to 250 units, the same standard of workmanship. Proven systems for portfolio-wide rollouts.
