## 1 Introduction
Based on the centralized data in the model, the construction process planning, the estimation of costs in an early project stage [9], and the achieving of a better buildings' performances in aspects related with comfort, efficiency and sustainability [10], can be easily elaborated. As the amount of data in BIM is rising exponentially, the value-relevant design information has not yet been widely utilized for property valuation or application. [PERSON] et al. [11] present a system that allows to improve information exchange between multi-projects, and automates specific workflows for property valuation. The present work intends to enlarge knowledge on the use of BIM model on the development with accuracy of several tasks. The ability of an enterprise to perform a task, deliver a service, or generate a product can be defined in distinct phases: Pre-BIM, BIM phase 1, BIM phase 2, BIM phase 3 and Post-BIM. These BIM phases or stages define the main goals to be achieved by teams and organizations as they adopt the BIM concept and associated technologies. Each BIM phase is defined based on establishing minimum requirements [12]. In this context, the term maturity corresponds to the adoption of admissible measures relative to a structure that encourages repeatable, stable, well-defined, and quality results. The maturity corresponds to the ability to differentiate the execution of tasks or delivery of BIM services or products, and it is defined as the degree to which business processes and activities are performed according to acceptable bases [13]. The structural design is an activity that requires a well-known management of the available software, concerning both the modelling process and the analyses practice [14]. The structural design process, supported in BIM software, have been widely studied, having in common the identification of the interoperability capacity of the systems, as the principal limitation on BIM implementation in this construction segment [15; 16; 17]. [PERSON] et al. [18] conducted a literature review in order to identify topics and trends on BIM interoperability problem with a focus on the structural analysis domain, from theoretic and application perspectives, identifying the most relevant interoperability problems and proposing possible solutions. A survey of 2014, promoted by [PERSON] and [PERSON], evaluates the structural projects percentage, whereBIM software is used, showing an average of 50%, in tasks concerning coordination (inter-disciplines), documentation prediction (drawings), analyses and design (using exterior analyses software) [19]. As interoperability is an inevitable step to take and analyze with care in project design offices, the present study aims to contribute to the investigation of the methodology implementation, in order to promote BIM adoption in this specific domain. Thus, the main objective of the work is to analyze, through a practical case, the implementation of the BIM methodology in structural design, complemented with the extraction of information supporting the development of a diverse type of tasks [20]:  
* Evaluating the efficiency of the BIM tools used in the elaboration of distinct phases of the structural design process (design, analysis and structural dimensioning);
* Exploring the various applications that the BIM model database can support related to different dimensions of the methodology (coordination, drawing production, construction planning, risk analyses, estimation costs, and sustainability simulation). In structural domain, the interoperability is the main problem that must be understood and the present study contributes to clarify the most recurrent limitations. The research also presents the capacity of BIM methodology of using the database of the BIM model to achieve several types of tasks that normally are associated to the structural design.
