| Parameters | Types | Importance of the parameter in EM_01 |
|
| Length | Geometric | These minimum geometric definitions associated with the wall panel or flooring systems allow not only to define the geometry and volume of the element but also to identify whether the panel can be prefabricated within the production plant, according to its restrictions, or even if it is convenient to assemble the panel on site due to other difficulties such as variable heights and double height panels |
| Thickness | Geometric |
| Height | Geometric | Likewise, as previously mentioned, length and thickness are key geometric parameters for the configuration of the multipanel system, since within the same table it is convenient to combine panels with the same height and thickness to avoid conflicts in the automated system associated with the CNC machines |
| Floor | Geometric | Early knowledge of this information allows for a better estimation of the costs and time associated with manufacturing and the tasks to be performed on site |
| Panel construction solution ID | Nongeometric | Knowing the type of construction solution associated with the panel is very important for the commercial evaluation performed by the off-site construction company, since it defines the materials to be used to manufacture the panel (coatings, insulation, framing, type of membrane, etc.). This is relevant not only to establish the unit prices of the solutions but also to quote their availability in the market |
| Panel weight | Nongeometric | It provides the order of magnitude of the project load and the identification of the most critical panels for the selection of lifting tools and machinery (and associated costs). Likewise, this information is relevant for configuring the loading of the panels on the transport trucks from the production plant to the project site |
| Anchorage specification (hold down or anchorage system) | Nongeometric | The cost of anchors is an important direct cost of the project, so knowing their specification at an early stage allows for their quotation and market availability study, and thus obtaining a much more accurate evaluation of the project cost |
| Cost per square meter of panel | Nongeometric | Basic information that allows quantifying the overall direct cost of the project, and it is associated with the parameter of the panel’s construction solution. Sometimes, various modification factors are applied to this parameter to quantify an increase in cost due to difficulties or particularities that the panel may have, for example, openings, installations, and special geometry |
| Panel ID | Nongeometric | It allows the identification and quantification of the project’s panels in addition to managing the information in a more organized manner |
| Panel fabrication table ID | Nongeometric | Although this attribute takes on greater relevance and is required in later stages of the evaluation, since it is key for the programming of factory production, the result of this research showed that knowing the configuration of the assembly tables is an important input that the improvement/optimization subprocess carried out by the off-site construction company can provide to the designers in early stages. This input is important because it allows for the estimation of the production time and costs associated with the project. It is also possible to make better decisions regarding production planning, which has a significant impact on costs during all phases of the project (production planning, transportation, assembly, etc.) |
