pump, valve, hvac system as-built walkdown checklist for industry

Pump System

  • Check that the pump is located in the correct position according to the design drawings.
  • Ensure that the pump is securely mounted to prevent any movement or vibration.
  • Examine the pump nameplate to verify important details such as pump model, serial number, and capacity rating.
  • Record the pump tag number for future reference.
  • Visually inspect the pump baseplate and foundation for any signs of damage or wear.
  • Ensure that the baseplate and foundation are stable and provide adequate support for the pump.
  • Check that the pump suction and discharge connections are correctly installed and aligned with the piping system.
  • Ensure that there are no leaks or loose fittings.
  • Inspect the alignment of the pump and motor coupling using appropriate alignment tools.
  • Ensure that the coupling is properly aligned to prevent any misalignment issues.
  • Visually inspect the pump motor for any signs of damage or overheating.
  • Record the motor tag number for future reference.
  • Energize the motor and observe the rotation direction of the pump impeller.
  • Ensure that the rotation direction is correct according to the design requirements.
  • Inspect the pump seals and packing for any signs of leakage or wear.
  • Ensure that the seals and packing are in good condition and properly installed.
  • Check the pump lubrication system, including oil levels and any lubrication points.
  • Ensure that the system is properly maintained and functioning correctly.
  • Visually inspect the pump control panel for any signs of damage or loose connections.
  • Record the panel tag number for future reference.
  • Check the wiring connections in the pump control panel for any loose or faulty connections.
  • Verify that the panel settings are correctly configured according to the design requirements.
  • Energize the pump control panel and test its functionality, including starting and stopping the pump.
  • Ensure that all control functions are working correctly.

Valve System

  • Check valve types (gate, globe, ball, etc.)
  • Record tag numbers
  • Verify manufacturer
  • Verify model
  • Verify size
  • Check body material
  • Check pressure rating
  • Inspect stem
  • Inspect bonnet
  • Inspect packing
  • Verify position indicator
  • Verify limit switches
  • Inspect stem seals
  • Inspect gaskets

HVAC System

  • Check the HVAC unit for a visible model and manufacturer information label.
  • Record the model and manufacturer information for documentation purposes.
  • Check the HVAC unit's capacity rating, usually indicated in BTU or tonnage.
  • Identify the cooling and heating sources used by the HVAC unit.
  • Confirm that the capacity and sources meet the required specifications.
  • Inspect the air handling unit (AHU) filters for dirt, dust, and debris.
  • Clean or replace the filters if they are dirty or clogged.
  • Inspect the AHU fan motors for any visible damage or wear.
  • Record the tag numbers of the fan motors for identification purposes.
  • Test the functionality of the AHU fan motors to ensure they operate smoothly.
  • Check the speed control settings of the fan motors and adjust if necessary.
  • Inspect the ductwork connections of the AHU for any leaks or loose fittings.
  • Ensure that all connections are secure and properly sealed.
  • Inspect the HVAC control system for any visible damage or malfunction.
  • Record the tag numbers of the control system components for identification purposes.
  • Test the functionality of the HVAC control panel, including all buttons and switches.
  • Ensure that the control panel operates properly and controls the HVAC system effectively.
  • Check the temperature and humidity sensors of the HVAC system for accuracy.
  • Verify that the sensors provide reliable readings and respond appropriately to changes.
  • Inspect the air distribution system components, such as diffusers, ducts, and grilles.
  • Check for any damage, blockages, or obstructions that may affect airflow.
  • Perform air balancing tests to ensure proper airflow and distribution.
  • Adjust the dampers if needed to achieve the desired balance and flow rates.
  • Inspect the insulation of the HVAC system components, such as pipes and ductwork.
  • Check for any signs of damage, deterioration, or inadequate insulation.
  • Verify that condensation prevention measures are in place and functioning correctly.
