Glass Project Site Visit: A Practical Pre-Purchase Checklist

t427-42

A glass project site visit confirms the real measurements, wall and floor conditions, access routes, and usage requirements before any glass is ordered. Doing this step carefully prevents costly remakes and delays for vitrines and glass partitions. Bring the plans, photos, and a list of questions so the visit produces a written specification you can approve.

Why the Site Visit Comes Before Ordering Glass

Glass is cut to exact dimensions, so every decision made before the visit has to be checked against the actual space. Walls are rarely perfectly square, floors may slope, and existing finishes can change the final fit. A proper site visit turns drawings and assumptions into verified measurements.

Treat the visit as the foundation of the whole project. It is the moment to confirm what the space really allows and to agree on details while changes are still easy and inexpensive.

Measurements to Take on Site

Measure the opening or area at several heights and widths, not just once. Note any out-of-level or out-of-plumb surfaces, because they affect how a partition or vitrine sits.

Width and height at top, middle, and bottom
Depth and clearance for vitrine doors and sliding panels
Position of columns, pipes, switches, and ducts
Floor level differences across the installation line

Record each figure with a photo and a short note so the drawing can be checked later.

Checking Walls, Floors, and Fixing Points

Confirm what the glass will attach to. Solid masonry, drywall, and existing tiles each require different fixings, and the fixing method changes how much support the glass gets.

Look for cracks, damp spots, and loose plaster. Check whether the floor is finished or will be tiled later, since a future floor level change can affect the bottom track of a partition. Ask whether any fixing points need reinforcement before installation.

Access, Delivery, and Installation Route

Large glass panels are heavy and fragile, so the route from the entrance to the installation area matters. Measure doorways, stairwells, and elevator sizes, and note any tight corners.

Clear path for carrying panels upright
Space for a safe working area during installation
Parking or loading options for the delivery vehicle
Times when the building allows heavy work

Knowing the route early avoids surprises on delivery day.

Lighting, Use, and Safety Requirements

Think about how the vitrine or partition will be used. Consider the light direction, reflections, and whether glare will affect staff or customers. For partitions, decide on privacy level, whether frosted or tinted glass is preferred, and how doors will swing.

Discuss safety expectations with the team, including impact exposure, children or public access, and the need for marked edges. Exact safety requirements should be confirmed with the project engineer against the applicable standards for your situation.

Documenting the Visit and Approving the Specification

After the visit, the supplier should prepare a drawing and a written specification listing dimensions, glass type, edge finish, hardware, fixing method, and installation sequence. Read it carefully and mark any point you do not understand.

Approve the specification in writing before production starts. A clear document shared by the client, designer, and contractor keeps everyone aligned and makes later changes easier to track.

Frequently asked questions

Who should attend the glass project site visit?

Ideally the project lead, the designer or architect, and the person responsible for the site. Having all decision makers present reduces back-and-forth later.

Do I need to be present for the measurements?

Yes, it helps to be there so you can point out details, approve sightlines, and answer questions about use. Photos alone rarely capture everything.

What if the walls are not straight?

This is normal, and the measurements should record the actual variation. The design can then account for it through adjustments and fitting details.

Can I make changes after the visit?

Minor changes are easier to handle before production begins. Once glass is cut, changes become more difficult and can affect timing, so confirm details first.

Common mistakes to avoid

Relying on old drawings or a single measurement taken from one point on the wall. Always measure on site at several heights and confirm the final figures before production.

Our recommendation

Bring a printed plan, a tape measure, a level, and your photos, and ask the supplier to put every agreed detail into a written specification you sign before production starts.

Summary

A thorough glass project site visit verifies measurements, fixings, access, and usage needs, and it ends with a written specification you approve before any glass is ordered.
