### Wood is hygroscopic and moves with changes in ambient humidity; delivering or installing woodwork before the building is dried in and HVAC is operational causes racking, twisting, and cracking that no amount of fabrication quality can prevent. {note}
−### The interior equilibrium moisture content (EMC) target for HVAC-controlled commercial interiors at 40–50% relative humidity is 7–8%; the delivered moisture content shall fall within the range required for the project's service environment. {note}

+# Veneer and Panel Faces {toc}
−### Veneer cut and match govern the figure and rhythm of a paneled wall; plain-sliced, quarter-sliced, rift-cut, and rotary cuts produce distinct grain, and book, slip, and random match arrange the leaves differently across each panel face. {note}

### Integrated assemblies such as reception environments and boardroom packages combine a casework base, veneer-faced panel faces, a transaction counter, and back-wall paneling into one engineered unit; the value of the umbrella contract is that one fabricator coordinates these interfaces rather than three trades meeting at a joint. {note}
−### The interface between paneling and casework at toe-kick and base conditions shall be detailed on the shop drawings as a defined gap, scribe, or reveal; an undetailed junction becomes a punch-list dispute. {note}

### The finish system is transparent (clear, showing the wood) or opaque (painted, concealing the wood), and is applied either in the shop (factory finish, the most controlled) or in the field; the choice drives species, core, and coordination with the painting trade. {note}
