Reception Desk Against a Bowed and Out-of-Square Wall
A shop is fabricating a 4.2 m reception desk for a renovated office. The plan view shows the desk against a straight wall; the elevation notes a 90° corner and a 600 mm cabinet depth. A site visit reveals the wall bows outward 18 mm at mid-run and the corner is 1.5° out of square. The dimension from the door frame to the partition is 3,600 mm on the drawing but 3,578 mm in the field. The designer wants a 20 mm reveal at the wall and a solid-surface countertop templated after cabinet installation. The desk includes a lockable drawer bank and a cable trough. The shop has already cut the cabinet ends to the drawing dimension. The project schedule allows one mock-up and a final site measure before release to production.
1. Explain how you would resolve the dimensional conflicts and what information you would request before fabrication continues.

I would not average the two dimensions or simply build to the drawing. First, establish which dimension controls the design intent: the door frame, the partition, or the desk itself. Then take a field survey at several heights and points along the run, recording the wall bow, the corner angle, floor level, and the door-frame-to-partition distance at both the floor and counter height. The 22 mm difference and the 1.5° corner error are large enough to affect the drawer bank and the countertop template.
I would issue an RFI with a dimensioned sketch and photographs, stating the measured values and asking the designer to confirm the datum and the acceptable reveal. I would request clarification on whether the 20 mm reveal is nominal or a maximum, whether the desk must remain square, and whether a scribe filler or a removable end panel is acceptable. Until that answer is received, I would not cut the end panels further. The already-cut cabinet ends should be checked against the mock-up and, if necessary, reserved for a less visible section rather than forced into the bowed wall.
2. Describe a layout and fabrication approach that accommodates the bowed wall and out-of-square corner while preserving the 20 mm reveal and drawer function.

Build the cabinet boxes square and independent of the wall. Use a story pole or laser to mark a level datum and a true reference line for the desk face. Set the boxes to the reference line with adjustable legs, then absorb the wall variation with scribe fillers or a removable scribe panel rather than by racking the boxes. At the corner, make a template of the actual angle and fit a separate corner filler or end panel so that the drawer bank stays square and the drawers do not bind.
Leave the wall-side end panels oversize until the final site measure. Set the reveal by working from the desk face, not from the wall; the 20 mm reveal should be measured from the high point of the wall and the filler scribed to the low point. Keep the countertop as a separate templated item, and do not use the cabinet top to force the wall straight. The cable trough should be positioned after the final layout so that it does not conflict with the filler or the drawer bank. A mock-up of the corner and one drawer bank will confirm clearances before full production.
3. What quality checks and shop/site coordination steps would you use before and after installation?
Read the worked answer
Before production, verify the mock-up against the field survey: check overall length, depth, corner angle, reveal, drawer clearance, and cable-trough position. Record the approved dimensions on a signed shop drawing. After delivery, set the desk to the datum and check level along the run, plumb at the ends, and diagonal measurements of each cabinet box. Confirm that the drawers open and close without rubbing, that the lock aligns, and that the cable trough is accessible. Check the reveal at the high and low points of the wall; it should be uniform or intentionally scribed, not forced. Confirm that the countertop template matches the installed cabinet and that the solid-surface fabricator has the final dimensions. Protect the desk until handover and obtain sign-off on the reveal and drawer operation. Any field change should go back through the RFI process rather than being cut on site without a record.
