Examining the need for a public procurement maturity model (PPMM) for infrastructure buyers in a monopsony market structure

Abstract

This paper examines the need for a Public Procurement Maturity Model (PPMM) in organizations with the role of road infrastructure buyers under public procurement legislation in a monopsony market structure. The environment used to contextualize the information is Romania and CNADNR (Compania Națională de Autostrăzi și Drumuri Naționale din România).

The literature research, open data as well as my own practical experience are used as entry data for the four parts of the paper: (i) the context leading to the PPMM need identification, (ii) an overview of the existing public (procurement) maturity models; (iii) discussions and (iv) summary, limitations, and outlook.

The paper provides arguments of an upstream intervention in the value chain of road transport infrastructure and highlights the benefits of such an intervention. Elements such as Romanian cultural dimensions, type of market structure or impact of the outcomes of public procurement process for road infrastructure are considered relevant entry data for an intervention which aims to contribute to the improvement of performance at a procurement process level.

The results of this paper serve as a starting point for further reflection on the performance in road infrastructure public procurement area in Romania. In addition to the awareness of the need for an intervention at a contracting authority level, the paper arguments that market structure or national cultural dimensions must be considered as entry data in designing maturity models.

Reducing the Seismic Vulnerability for RC Buildings by Using Steel Bracing Elements

Abstract

This article aims to highlight, through a comparative study, the efficiency of steel bracing systems used to reduce seismic vulnerabilities in existing buildings with reinforced concrete structures (reinforced concrete frames and reinforced concrete dual structures, general building structures including those used in transport infrastructure). In order to simplify the calculations, the analysis was reduced to the study of the behavior of resistance lines corresponding to four-, nine- and fifteen-level buildings with the same plane distribution. In order to obtain features similar to those of existing building elements, structures were initially loaded with seismic forces corresponding to code P13-63. The next step was to apply to previously dimensioned structures the seismic loads according to P100-3: 2008 in relation to P100-1: 2013, thus obtaining the deficiencies of the existing structures against the requirements of these norms. Correction of these strength and stiffness deficiencies was attempted by introducing X-shaped centric brace systems. The bracing systems used as consolidation methods are of three types: direct bracings stuck in the reinforced concrete frames and bracings of the indirect type, made of internal and external bracing steel frames. Structural calculations were made in the linear elastic field using the ETABS program.
