The survey should establish how the proposed generator connects to the site, where it can be positioned and what surrounds it. Record the existing electrical arrangement, relevant equipment identity and access restrictions. The assessment may need to cover foundations, ventilation, exhaust, fuel and maintenance space as well as cables and switchgear. The applicable scope depends on the project.
Record constraints precisely
Photographs are useful when they are tied to a location and a clear description. Measurements, route lengths, equipment labels and drawings make the survey more actionable. Identify what could not be inspected and any assumptions that need confirmation. A drawing of a proposed position should not conceal an unresolved access, airflow or connection constraint.
Application details
The site determines whether the proposed power system can be installed, operated and maintained effectively.
Do not survey only the empty space
- delivered
- positioned
- connected
- fuelled
- maintained
- possibly removed
Include the complete cable route
Survey the route as well as the proposed generator position. Record changes in installation conditions, access, mechanical protection, joints and termination locations. These details influence electrical design, installation work and later maintenance access.
Connect observations to decisions
The survey record should explain which observations affect equipment selection, installation planning or further investigation. Existing conditions may require specialist review or coordination with other trades before a final arrangement is agreed. Share current drawings and operational restrictions ahead of the visit where possible. This helps the survey focus on the questions that must be answered to progress the project.

Engineering intent
Generator Site Survey should be evaluated as part of the complete power system rather than as an isolated catalogue item. Operating duty, connected load, interfaces, protection, controls, installation conditions, testing requirements and lifecycle consequences determine whether the arrangement is appropriate.
Engineering considerations
Temporary-power deployment, rental access, cable route and short/medium-term operation. Permanent or project generator installation, existing electrical architecture, room/site interfaces, lifecycle maintenance, future serviceability and design basis. Before measuring cable distance or locating a generator, define the application. The survey depth should follow the application and consequence. A generator site survey is therefore not only about physical space. It is about whether the site can support the required operating outcome. A site survey should connect to the load basis. A generator must integrate with the electrical system that already exists. The generator should fit the electrical architecture—not force the architecture to fit the generator. The survey should compare drawings with observed site conditions.
Selection and design considerations
The electrical site survey exists to answer one governing question: CAN THIS GENERATOR SYSTEM BE INSTALLED, CONNECTED, PROTECTED, OPERATED AND MAINTAINED CORRECTLY AT THIS SITE? Survey the Site Before the Site Redesigns the Generator Project. An electrical site survey is a structured technical review of the physical and electrical environment where a generator system will be installed or connected. • how the power path will reach the load; • whether ventilation, exhaust and fuel systems can be implemented; • what information is missing before design or quotation. It is the beginning of the installation design basis. A site that accepts a generator today but cannot support maintenance tomorrow is not fully ready. Can that source be installed and integrated into the real site?
Integration and protection considerations
Noise restrictions may change where the generator can operate. Flooding or weather exposure may change the installation. That is why a professional rental project should not ask only: “What site must this temporary power system actually work within?” A rental site survey is the structured assessment of the physical and electrical environment in which a temporary-power system will be installed, operated, maintained and eventually removed. “This is how temporary power can realistically be delivered, connected, protected, fuelled, operated and supported at this location.”
Testing, commissioning and verification
Provide the generator model and expected loading so the appropriate consumption basis can be identified. The recovered Rental Power master says the survey should evaluate the load/duty profile, existing electrical architecture, connection points, fault level, voltage/frequency, access, positioning, ground-bearing capacity, noise, exhaust, fuel access, environmental exposure, flooding, cable routes, earthing, emergency access and future expansion. Before the Generator Moves, Understand the Site It Must Serve. A temporary-power project can be correctly sized on paper and still become difficult, expensive or unsafe when it reaches the site. The generator may be unable to reach the proposed location. The proposed position may not support the equipment. The cable route may be substantially longer than expected.
Operating and lifecycle considerations
A site survey records and structures the engineering basis. Those require the appropriate project-specific engineering and documentation. Before temporary equipment is dispatched, confirm where applicable: Not every question has to be closed at survey stage—but high-impact unknowns should be visible. An emergency may not allow a full preplanned survey. But urgency does not remove the need for safe site information. Planned outages provide the best opportunity to inspect the site before normal power is isolated. The survey should understand the process as well as the site.
Direct answer
The survey should establish how the proposed generator connects to the site, where it can be positioned and what surrounds it. Record the existing electrical arrangement, relevant equipment identity and access restrictions.
The practical decision for Generator Site Survey should be based on verified load, equipment, interface and site information. Where equipment-specific data, regulatory applicability or a project study is required, this guidance does not replace that verification.
