This luxury flat in one of the most high-end residential tower taught me a valuable lesson.
The units in this building, if I recall correctly, occupy half the floor, and this owner had two of them. Newly-built by one of the most highly regarded developers with units in the high 8 figures, one would presume the construction accuracy to be unparalleled. We made that assumption at the onset, which then led to some expensive challenges downstream.
We installed the 2cm Bianco Carrara Italian Marble slabs like we did in any other project. Upon completion, it was determined the floor portion installation by the window was slightly tilted towards the glass. Though imperceptible to the naked eye, the slope was there, and since it pleased the client to level the floor to absolute perfection, we brought in the heavy duty wet polishers to grind and remove a millimeter or two to achieve the accuracy expected of Kaufman Stone.
We wanted to know what caused this to occur. The room was bound by an entrance door, existing wooden floor, window and kitchen. All these were already provided by the developer when we arrived. When we levelled all those points, it was then made flat and even. But upon delving further into the mystery, the floor was perfectly aligned to the main door and kitchen. All those points were accurate, but when the floor line arrived at the two windows we discovered the culprit. The floor had, indeed, been forced to angle downwards (since the window moulding was lower than the rest of the points by a few millimetres), hence, the floor needed to be adjusted downwards by our masons, causing the slope and my additional cost.
The moral of the story is to measure and re-measure. If any defects are found from other traders’ work, immediately inform the client. If any errors are detected in the space turned over to you from the owner’s side who will be receiving the stone, report this without delay. In so doing, in the interest of fair play, you can allocate the liability to the party responsible for the defect.
