Defining Robustness In the Caribbean (Periodic Design Reviews)

• Atrium prescribed initially to be naturally ventilated all year round

• Thermal shock between conditioned spaces and atrium resulted in a revised design with some mechanical ventilation now to be integrated

• Louvers motorized and designed to withstand Category II Hurricane

• Designed to only provide 90 minutes of direct sunlight per day to patient rooms

• Metal components treated with a special coating to minimize the effects of corrosion from the abrasive marine environment



• Chiller spacing and pipework arrange to adhere to manufacturer’s access and maintenance requirements

• Chiller and pipework design including insulation to withstand marine environment

• Chiller evaporation fans retrofitted to reduce air contamination by diesel generator fumes



• Chiller water pump, valve, and sensor arrangement evaluated during design and via submittal reviews

• Access and maintenance requirements evaluated for conformity with manufacturer’s requirements

• Insulation selection also reviewed. Although this plant room is enclosed, there is no vestibule between this room and the exterior

• Test was performed with the dooropen for a period of time toevaluate condensation risk



• Switch gear and transformer design were part of the scope

• Switchgear called for factory acceptance tests for circuit breakers, ammeter, voltmeter to be included in the specifications

• Access and maintenancerequirements were alsoevaluated



• Specific requirements by the utility company or AHJ (Aqualectra) were incorporated

• Transformer winding resistance,ratio, and vector group tests forthe transformers were evaluated

• Air Handling Unit filter specification design EU7, EU9, and M4 or EU13• Corrosion ablation in pre-filter section of AHUs was looked at due to the marine

environment



• Air Handling Unit ductwork design to ensure conformity of ductwork bends, bend angles, insulation selection, joints, hangers and most importantly, linearity of insulation, both for the exterior and interior AHUs



• Air Handling Unit controller valves, pumps, fans, air dampers, heat exchangers, temperature sensors were also evaluated

Pre-functional Checklists – Site Acceptance Tests


• Commissioning daily kickoff meetings – some if offices and others onsite were a stable of the project.• The commissioning plan and the goals for the day were addressed before activities commenced• Commissioning team including members of all stake holders – operator, operator Cx, Baumann, GC

and GC Cx team



• Commissioning team including members of all stake holders – operator, operator Cx, Baumann, GC, GC Cx team and controls contractor

• Attendee sheet to document all members present, date of the test and some information about theday’s tests



• Testing Agenda▪ Alarm Conditions▪ Visual Inspections▪ Sensor Verifications▪ Sequence of Operation Verifications

◦ Equipment Status Confirmations◦ Temperature Controls◦ Volumetric Flow Controls◦ Pressure Drop Controls◦ Enthalpy Controls◦ MCC Panel Verifications◦ Room Conditions◦ Power Draw Evaluations◦ Emergency Power Tests◦ Fire Alarm Tests



• Alarm conditions were clarified before any test to ensure that health and safety issues were clarified and understood



• A visual inspection by all stakeholders is performed to assess the quality and stability of all the installed equipment

• A checklist is created to document all defects and assign timelines for repairs and persons of responsibility



• Sensor verification via a confirmation of the building automation system data readings verified by field measurements

• This initial test was often performed to confirm the status of the equipment and document this before any tests could commence


Functional Performance Tests – Site Acceptance Tests


• Functional Performance Tests – Status verification via the BMS and through field visualization tests



• Sequence of Operation Verification – Temperature controls to verify design intent• Tolerance for acceptable results – +/- 0.5 degrees Celsius for the water systems and +/- 1 degree Celsius

for the air systems



• Sequence of Operation Verification – Volumetric flow control verification



• Sequence of Operation Verification – Pressure drop controls verification



• Sequence of Operation Verification – Enthalpy controls via run around coils and thermal wheels



• Sequence of Operation Verification – MCC panel verification



• Sequence of Operation Verification – Room conditions (temperature, humidity, pressurization were also verified



• Sequence of Operation Verification – Power draw evaluation of installed equipment



• Sequence of Operation Verification – Emergency condition was also simulated as part of SIT after SAT• Sequence of Operation Verification – Fire condition was also simulated as part of SIT after SAT



• Sequence of Operation Verification – Commissioning reports



• Sequence of Operation Verification – Issues log• Blend of web-based platform (ED Controls, CxAlloy) and paper-based issues sheets• Issues are correlated and assigned to different trades thought the GC



• Mis-aligned inline CHW pump which resulted in pipework leakage and excessive pump vibration.• Improper sealing of the duct penetration between two fire zones basically negating the fire separation.• Controller damage via glue used to seal insulation. Controller was stuck and stopped modulating.• Improper grounding of AHU to protect against electric shock during power surges or lightning.



• Pipework corrosion damage due to gluing of the connections during insulation application • Glued insulation improperly installed and not sealing the pipework properly• Excessive vibration from exhaust fan due to misalignment during installation• Exhaust fan BMS communication issues (“off” on BMS, “on” during field observation)



• Non-functioning room thermostat and thus no signal received in the BMS• Improper labeling or in some occasions, no labelling installed• Improper AHU panel installation – with visible gaps causing leakage and whistling• Leaking chilled water pipework – someone apparently used the lower pipework as a step ladder



• AHU frame support improperly installed and, in this case, not level• Controller incorrectly installed – opposite signals between 0 to 10v – closes when signaled to open etc.• Duct penetration to roof not properly sealed exposing the equipment below to water penetration and debris• Ductwork support not properly secured resulting in breakage is the ductwork seals



• Chiller controller bottom plat cover not installed – negating the chiller IP (ingress protection) rating • BMS communication issues with sensors and actuators identified during Site Acceptance Tests• Condensation observed below main CHW pipework due to the high humidity in the plantroom• Corrosion observed on vibration isolation equipment. Repainting necessary
