Boiler Plant Retrofit Project

Mechanical — heating & domestic hot water

Scope & engineering summary

This project involved the replacement of the existing boiler plant of 1,000 MBH capacity. The design decoupled the domestic hot water system from the heating plant for energy savings in summer when heat is off. Both systems used primary-secondary configuration to decouple system pumps.

Key deliverables

1,000 MBH heating plant replacement
Domestic hot water decoupled from heating plant for seasonal savings
Primary–secondary pumping on both heating and DHW sides

Indicative construction value

$750,000.00

Chiller Retrofit Project

Mechanical — central plant & HVAC

Scope & engineering summary

This project involved the replacement of an existing 800-ton chiller with two new magnetic-bearing chillers. The chillers were configured in a primary-secondary loop system; condenser and evaporator pumps were replaced with duty/standby equipment. The design included refrigerant leak detection and an associated purge exhaust system.

Key deliverables

800-ton legacy chiller replaced with two magnetic-bearing machines
Primary–secondary chilled-water configuration
Condenser and evaporator pumping converted to duty / standby
Refrigerant leak detection plus purge / exhaust integration

Mechanical — tenant / base building fit-out

Scope & engineering summary

This project involved the retrofit and fit-out of an existing office of approximately 30,000 ft². HVAC and plumbing/drainage systems were removed back to their respective mains, and new design was provided.

Key deliverables

~30,000 ft² office retrofit and fit-out
HVAC stripped to mains with full re-design and distribution
Plumbing & drainage systems replaced from mains outward

Indicative construction value

$1,500,000.00
