The Pre-Order Site Survey: 14 Checks Before a Multi-Country Display PO

The most expensive mistake in a display rollout is not choosing the wrong panel. It is choosing the right panel and discovering, on site, that it cannot get through the door. A pre-order site survey costs a few hours per location. Skipping it costs re-orders, restocking fees, a second freight leg and a delayed handover, and on a multi-country programme those costs multiply by every site that shares the same wrong assumption. This is the checklist we ask buyers to complete before a purchase order is raised.

Quick reference: the 14 checks

  • 1. Wall construction and whether it will carry the load
  • 2. Structural backing behind plasterboard, and where the studs actually are
  • 3. Power at the mounting position, and the local voltage and plug type
  • 4. Circuit capacity and whether the room is on a protected supply
  • 5. Data point at the panel, or a decision to run one
  • 6. Cable route from the panel to the source position
  • 7. Ceiling height and the mounting centre line
  • 8. Viewing distance from the furthest seat
  • 9. Glare from windows and light fittings
  • 10. Door widths and corner clearances on the delivery path
  • 11. Lift access, dimensions and weight limit
  • 12. Floor level and access for trolleys and stands
  • 13. Site rules: working hours, permits, escorts, insurance
  • 14. Who signs the acceptance, and where the packaging goes

The wall: can it hold the panel, and can you find the studs?

An 86-inch commercial panel with a mount is commonly 70 to 90 kg. That is a straightforward load for a concrete or blockwork wall and a real question for plasterboard, glass partitions and the decorative panelling common in Gulf offices and ministry buildings. Record the construction type for every room, not for one sample room, because fit-outs change between floors. Where the wall cannot carry the load, the answer is usually a floor stand or a mobile trolley from our mounts and stands range rather than structural work, and that decision changes the order, so it has to be made before the PO.

Find the structural backing while you are there. A plasterboard wall with timber or steel studs at 400 or 600 mm centres may take the panel perfectly well if the bracket lands on the studs, and not at all if it does not. Photograph the wall with a stud detector reading visible, and note the centres. On refurbishment projects, ask whether backing plates were installed behind the board; if the fit-out contractor put them in, you will want the drawing.

Power, data and the route between them

Check that there is a socket behind or beside the mounting position, not four metres away at skirting level. Note the local voltage and plug type for every country in the programme, because a rollout spanning the GCC and West Africa will cross 220-240 V with several different plug standards, and the wrong cable set in the box is a nuisance at every site. Confirm whether the room is on a protected or generator-backed supply where that matters; in markets with unreliable grids this determines whether a UPS goes into the order, a point we cover in our guide to powering displays in unstable grids.

Then trace the cable route. The panel needs a path to wherever the source sits, whether that is a lectern, a table box or an equipment cupboard. Note the distance, because beyond about 15 metres a straight HDMI run stops being reliable and an extender or a different distribution approach has to be priced. Surface trunking on a ceremonial wall is rarely acceptable, so if there is no containment, that is a cost and a programme item, not a detail.

Sizing the room, not the wall

Ceiling height sets the mounting centre line, and the centre line sets the maximum panel size. A room with a 2.4 metre ceiling and a requirement for the bottom of the screen to clear a credenza will not take a 98-inch panel however wide the wall is. Record the ceiling height, the height of any furniture below the mounting position, and the resulting available vertical space.

Measure the distance to the furthest seat as well. Undersizing is the most common regret in interactive display projects, and it is entirely avoidable with a tape measure. Where the survey shows the room needs a larger panel than the standard specification, it is far cheaper to change the line item now than to replace it after handover. Note window positions and light fittings while you are in the room: a panel facing a west-facing window in the Gulf needs higher brightness and a matte finish, which again is an order decision.

Getting the box into the room

This is the check that actually causes re-orders. A boxed 86-inch panel is commonly around 2 metres long and 1.3 metres high, and it does not bend. Measure every door on the delivery path, every corner the crate has to turn, and the lift: internal dimensions, door opening and weight limit. A goods lift that takes the weight but not the length is a very common failure. If the crate cannot make it, the options are a smaller panel, a different delivery method such as a hoist or an external lift, or an unboxed carry with the manufacturer's agreement, and all three affect cost and risk.

Note the floor level and the access route for trolleys. Steps, thresholds, gravel and soft ground all matter when two people are moving 80 kg of glass. On African sites in particular, confirm whether the final approach is sealed, because it changes the delivery vehicle. Our guide on shipping displays across Africa and the GCC covers the freight side; the site survey covers the last fifty metres, which is where most damage happens.

Site rules and who signs it off

Finally, the administrative checks that stall installations. Confirm permitted working hours, whether a work permit or a hot-works permit is needed, whether installers require escorts or security clearance, and what insurance documentation the building manager expects. Confirm who signs the acceptance certificate on the day and what they will test. And confirm where the packaging goes, because a school or ministry with thirty crates and no disposal arrangement will hold your installers on site.

Do this once per site type rather than once per room where the estate is genuinely uniform, but be sceptical about uniformity. Our guide to multi-country rollouts sets out how to standardise a specification across borders, and the pre-order survey is what tells you where the standard has to flex. The output should be a one-page record per site attached to the PO, so that the packing list, the mount type and the cable set leave the warehouse correct for that address.

FAQ

How long does a pre-order site survey take?

Around thirty to sixty minutes per room for a competent surveyor, less where rooms are genuinely identical. The delivery-path checks are done once per building rather than once per room.

What is the most common problem a survey finds?

Access. Door widths, corner clearances and lift dimensions cause more re-orders than wall construction does, because a panel that cannot reach the room has to be exchanged for a smaller one.

How much does an 86-inch panel weigh?

Commonly 70 to 90 kg including the mount, which is straightforward for concrete or blockwork and a real question for plasterboard, glass partitions and decorative panelling.

Can we survey one room and apply it to the whole estate?

Only where the estate is genuinely uniform, and it usually is not. Fit-outs change between floors and between buildings, so survey each site type and check the delivery path at every building.

What should the survey produce?

A one-page record per site attached to the purchase order, so the mount type, cable set and plug standard leave the warehouse correct for that address.
