Minimum nongeometric parameters associated with the development of prefabricated timber projects.

ParametersDescription/UsesExchange models (EMs)

Panel construction solution IDIdentifies the type of construction solution designed for the panel, i.e., the configuration of its timber core (cross section, spacing, and structural grade) and the rest of the cladding layers of the solution (e.g., bracing plates, termination plates, and insulation)EM_01–EM_05
Panel weightRelevant for panel loading control and to be able to quote the correct equipment, relevant for the analysis of lifting systems and logisticsEM_01–EM_05
Anchorage specification (hold down or the anchorage system)Parameter that may be relevant in case the logistics of the anchorage elements is the responsibility of the manufacturing plant and requires information on their specification. The importance of this parameter lies in assuring that the CNC machining to be performed on the panel correctly installs the anchor according to the project designEM_01–EM_05
Panel has MEP installationsIdentifies whether the panel in question has electrical, mechanical, or plumbing installationsEM_02–EM_05
Panel assembly locationDefines where the panel is to be assembled, either in the factory or on siteEM_03–EM_05
Number of additional studsRelevant for correct panel assemblyEM_03–EM_05
Interior and perimeter plate nailing patternRelevant for material quantities, cost estimates of the off-site construction company, and correct execution of the patterns in plant according to the design specificationsEM_03–EM_05
Cost per square meter of panelRelevant for cost estimation and financial evaluation of the projectEM_01
Panel IDRelevant for the identification, management, and control of the panel to be manufacturedEM_01–EM_05
Panel fabrication table IDRelevant for plant planning and production capacity. Obtaining this parameter involves a process of analysis and optimization during the design phase of the projectEM_01–EM_04
Transport identifier codeCode identifying the package and/or truck where the panel in question will be transportedEM_04–EM_05
Identifier code to indicate the company/shift that manufactures a panelIdentifies the team responsible for manufacturing the panelEM_04–EM_05
Identifier code of procedures/details at the factoryA code or description associated with a procedure or detail to be performed in the manufacture of the panel (reinforcement with screws, insulation placement, etc.) is definedEM_04
Site/assembly procedure identifier codeIndicates if the panel requires a special procedure on site or during assembly, e.g., special lifting requirements and reinforcementEM_05
Panel assembly sequence identifier codeCode specifying the order in which the panel is assembled on siteEM_04–EM_05
Wood structural gradingSpecifies the structural grade of the wood used on the panelEM_02–EM_05
Type of treatment applied to the woodSpecifies if the wood used for the panel considers a specific treatmentEM_04
Acoustic, waterproof, or fire seals IDIndicates if the panel requires the installation of special seals, either on site or at the plant to ensure regulatory requirementsEM_04–EM_05
Storage conditionsSpecifies if the panel requires any special storageEM_04–EM_05
Equilibrium moisture in plantSpecifies the equilibrium moisture as the condition in which the panel was manufacturedEM_05
