Engineering RFQ & Shutdown Checklists

Explore the relevant engineering page or send a technical requirement. Recommended RFQ inputs: project/asset, existing OEM/model, scope, drawings or specification, required date, site location, and any shutdown/mobilization constraint.

E-House enquiry checklist

What an estimator needs before an E-House or modular electrical room can be priced. Send what exists; a partial list is still worth reviewing.

Electrical scope

Single line diagram, or the intended distribution arrangement
Voltage classes and system earthing
Fault level and duration at the incomer
Equipment list: switchgear, MCC/PCC, drives, UPS/DC, transformers
Load list, with duty and starting method for motor loads
Control and automation scope inside the building

Building and environment

Internal arrangement or space envelope, and access requirements
Ambient temperature range and solar loading
Area classification, if any part is in a hazardous zone
Ingress protection, fire and blast requirements
HVAC duty, redundancy and control philosophy

Transport and site

Transport route limits: weight, width, height, lifting arrangement
Site location and installation interfaces (cable entries, earthing, foundations)
Whether site installation, termination and commissioning are in scope

Project

Project stage: FEED, tender, execution, operating, shutdown
Required delivery date and any shutdown or mobilization window
Applicable standards and client specifications
Documentation, FAT and witness requirements

Gathered what you can? Send it with the enquiry — an engineer reviews the scope and replies.

Control system migration readiness checklist

Before a PLC, SCADA or DCS migration can be scoped, these are the things that decide whether the existing installation can be kept and how the cutover is planned.

Existing system

Make, model and firmware of the existing controllers and HMI/SCADA
Application backup: program, tags, graphics, historical configuration
Spare-parts position and known obsolescence notices
Fault and downtime history, with the events that triggered the review

Field and I/O

I/O list with signal types, ranges and locations
Condition and age of field wiring, marshalling and terminations
Whether existing cabinets, racks and field wiring are to be retained
Instrument and final-element list, with anything already scheduled for replacement

Interfaces

OEM packages and third-party systems that must remain connected
Protocols in use, and which are available on the new platform
Safety system boundary, and whether it is in or out of scope
Historian, reporting and any remote-monitoring interfaces

Cutover

Available window: shutdown, turnaround, phased or hot cutover
Acceptable loss of view and loss of control durations
Fallback and rollback plan, and who authorises it
FAT scope, site acceptance criteria and operator training needs
