COMMERCIAL MECHANICAL • JOC • FACILITY RENEWAL

Job Order Contracting & Facility Renewal

EST supports public, institutional and commercial facility teams with mechanical scope development, line-item estimating, equipment replacement, hydronic and airside work, shutdown planning, supervised field execution and documented closeout.

Field-Verified ScopeExisting conditions, quantities, interfaces and access
Mechanical ExecutionEquipment, hydronics, sheet metal, controls coordination
Turnover DisciplineTesting, startup support, O&Ms, warranties and closeout

FROM FACILITY NEED TO WORK ORDER

A Mechanical Delivery Path Built for Existing Facilities

Facility-renewal work usually starts with an existing condition—not a blank sheet. EST develops the work around what is actually in the building, the procurement path available to the owner and the sequence required to return the system to service.

01

Verify & Define

Confirm equipment, piping, duct, controls, utilities, access, shutdown boundaries and measurable quantities.

02

Price & Procure

Build the applicable line-item estimate, identify project-specific requirements and coordinate procurement/submittals.

03

Execute & Close Out

Manage field installation, testing, startup coordination, punch, warranties, O&Ms and turnover documentation.

FACILITY RENEWAL SCOPE

Mechanical Work That Extends Facility Life

EST focuses on the systems that most often drive capital renewal, deferred-maintenance correction and occupied-facility upgrades.

Commercial boiler plant and mechanical room equipment

EQUIPMENT RENEWAL

Chillers, Boilers, AHUs & RTUs

Equipment replacement coordinated with rigging, utilities, controls, piping, duct transitions and return-to-service requirements.

Commercial hydronic piping valves and mechanical equipment connections

HYDRONIC RENEWAL

Mechanical Rooms, Pumps & Piping

Carbon steel and copper piping, valves, strainers, gauges, pumps, supports and equipment interfaces built around existing conditions.

Commercial sheet metal ductwork and air distribution installation

AIRSIDE RENEWAL

Sheet Metal & Air Distribution

Duct demolition, renovation, transitions, exhaust, air distribution and equipment connections for occupied and phased work.

WHERE JOC FITS

Built for Recurring, Time-Sensitive and Existing-Facility Work

JOC can be useful where owners need a repeatable construction pathway and the work benefits from measurable scope, established pricing rules and disciplined field execution.

01

End-of-Life Equipment

Replacement of aging HVAC assets before reliability or availability becomes a larger operational problem.

02

Deferred Maintenance

Mechanical deficiencies grouped into executable repair and renewal scopes instead of isolated service events.

03

Occupied Renovations

Phased work, shutdown windows, access constraints and trade coordination planned around ongoing facility operations.

04

Recurring Facility Programs

Repeatable mechanical scopes where the owner benefits from a consistent procurement and execution framework.

PROCUREMENT & TECHNICAL RESEARCH

Useful Resources for Owners, Designers & Facility Teams

External references support procurement and equipment research; EST’s field verification, project documents and current quotations remain the controlling basis for project execution.

MECHANICAL JOC STARTS WITH SCOPE

Bring EST the Facility Need.

We can begin with field conditions, constructability, quantities, procurement requirements and schedule so the mechanical scope is built for execution—not just pricing.
