It was found out that the process costs for overall, columns, and beams of method A were not statistically different from method B, while the slab process cost was significantly different. A statistical t-test was conducted for both process costs and time durations to differentiate between the two methods. The output parameters after the BIM simulation were processed cost and time. Two methods were considered: method A (traditional forms) and method B (steel decks). In this study, simulation using BIM was made from input parameters taken from actual project observations and data collection from five projects. Cost and time are the parameters commonly considered to address which method is recommended for a project. In the Philippine construction industry, choices of formwork methodology is critical to contractors or client/project managers.
Enhanced usability of such a forming system is achieved through the use of a material reliable in operation and easy for processing.

ease of processing), is free of its drawbacks, a “transformer” form is flameproof and moisture resistant. Because porous artificial wood, having all the benefits of natural wood (i.e. The newly developed forming system is consistent with the environmental safety requirements, having a deck made of porous artificial wood instead of natural wood, as was previously substantiated by the authors’ calculations. It is also technology intensive, requiring approximately 3-4 times less labor effort as compared to conventional small-panel forms used for reconstruction and overhaul of construction systems. A prefabricated “transformer” decking is a versatile forming system, which can be arranged both as a three-dimensional closed P-structure and as a flat structure, depending on the purpose or type of a specific structural element to be strengthened and the work method to be employed. The authors suggest a new forming system designed for strengthening certain structural elements, by means of widening, for the purpose of reconstruction of buildings and works. This research aims to guide designers in the building industry to properly determine approaches for developing GD-BIM and inspire researchers’ future studies. Finally, future research directions, challenges, and potential solutions are discussed. Accordingly, novel perspectives of objective-oriented, GD component-based, and skill-driven GD-BIM development as well as reference guides are proposed. This study conducts a critical review of current approaches for developing GD in BIM, and analyses methodological relationships, skill requirements, and improvement of GD-BIM development. However, there are a lack of studies regarding methodological relationships and skill requirement based on different development objectives or GD properties thus, the threshold of developing GD-BIM still seems high. Thus, there has been an increasing interest to study GD-BIM, with current focuses mainly on exploring applications and investigating tools. The integration of generative design (GD) and building information modelling (BIM), as a new technology consolidation, can facilitate the constructability of GD’s automatic design solutions, while improving BIM’s capability in the early design phase.
