Structural Building Condition Reviews: Beyond Distress

A major key indicator for assessing the quality of an urban residential neighborhood is the building condition. A good building condition adds value to a neighborhood in terms of aesthetics, safety, security and comfort. The Rivers State Government has in 1986 - 1998 built 12 residential estates for her staff members in the study area. The responsibility of maintenance of the buildings has been left to the owner occupiers of those houses. What is the state of those houses which has been built for over 30years? It is on this note that this study is poised to ascertain the physical condition of buildings within the public housing estates in Port Harcourt municipality. This study is a quantitative research that belongs to the class called “descriptive research design”. Simple random sampling technique was used to select 108 respondents (household heads) from the six selected housing estates. Questionnaire, physical observation and digital camera were the tools used for data collection. Analysis of findings was presented descriptively in tables, charts and percentages. Among the twelve public housing estates identified within the study area, the simple random sampling method was used to select and study six of the estates which are: 1. Aggrey Housing Estate, 2. Marine Base Govt. Housing Estate, 3. Abuloma housing estate phase, 4. Ndoki Housing Estate, 5. Elekahia housing estate and, 6. Khana Street Housing Estate. The research findings show the physical condition of buildings within the public housing estates, 81.5% of the buildings has good foundation, 92.6% of the windows are in good condition, 95.4% of the buildings have water system. 65% of the respondents considered the overall housing condition of the estates as good (needs no repair) while 35% saw the housing condition as fairly good (needs minor repair).

Building Condition

The problem of multi-family building maintenance is complex and comprises numerous issues, one of which is the process of planning expenditures for residential building renovation. This task is important from the manager’s point of view as their responsibility is to maintain a building in a non-deteriorated condition. To fulfil this task, the authors of this paper suggest utilising a decision-making model aimed at defining renovation activities making it possible to retain the maintenance standard (as regards newly commissioned residential buildings) or improve it (as regards existing buildings). The suggested model is based on a multi-criteria building assessment including seven requirements. The calculations conducted using the suggested model enable us to define the costs and scope of renovation taken to ensure the assumed building condition or, by assuming various rates paid to the renovation reserve, to define the period in which the above-mentioned goals may be achieved.

Decision Making Tool

There are many buildings with various conditions in Indonesia and some of them are not in finest conditions that need maintenance treatment urgently. The absence of building maintenance decision-making tool and limited budget are among main factors that cause unmanageable maintenance program. Therefore, this study has been conducted to propose an optimization model that is capable to determine the most appropriate building maintenance treatment. This study applied Constraint Programming (CP) approach to select the most economical maintenance treatment for a certain building and to allocate annual maintenance budget. CP-based model in this study subjects to constraint of budget and targeted level of building condition. In this study, maintenance treatment options, budget, time period, building deterioration rates, and the minimum standard of building condition were set. The model was run in IBM ILOG CPLEX Optimization Studio since the software is very efficient and effective in processing the optimization model. Furthermore, a case study was carried out to run the model involving 41 buildings in a 10-year period, and two different scenarios were conducted to examine the optimization model. The results successfully validated that the model can be a decision-making tool in selecting and prioritizing effective maintenance treatment.

Abstract The Building Performance Indicator (BPI), not fully applied in Brazil, expresses objectively the overall condition of a building based on the performance assessment of the building systems that comprise it. Although BPI was originally developed for hospital facilities, it can be used in different types of buildings since its methodology is generic. The objective of the study is to adjust the BPI to allow its application in the maintenance management of Brazilian university buildings. The stages of the research consist of (1) adjusting the factors and criteria that comprise the BPI; (2) implementing the adapted BPI; and (3) verifying its utility and ease of use. The adjustment and implementation included a building for classrooms and another that houses a teaching and research laboratory, both located at University X. The results obtained allowed the comparison of the overall condition between the inspected buildings, which establishes the intervention priority helping to adopt the most adequate maintenance strategy.

Building Condition

This paper introduces the concept of a BIM-based life-cycle management system for reinforced concrete buildings. The system allows one to compute a prognosis of the building’s condition taking into account the material properties of individual components, the environmental load as well as measurement data from current inspections. This prognosis then forms foundations for scheduled maintenance and repair actions in an economically efficient way. A particularly important feature of the presented system is that all input data as well as the computational results are associated with a (full) 3D Building Information Model (BIM) of the construction. In this way, an easy localization of the information is achieved facilitating both the data collection and the estimation of the building condition for engineers involved in inspection planning, inspection or the scheduling of repair actions. To further facilitate data input and interpretation, a hierarchic level-of-detail approach is employed for structuring the building model, ranging from building level down to individual hot spots. Additionally, the integration of a meta-model allows the flexible adaption of the semantic data model to specific buildings types or the particular needs of the users.

The aim of the paper is to explain the basic principles of carrying out an inventory and follow-up of buildings and their condition assessment, by using the Full Interactive Visualization Method for Building Condition Assessment platform. It is a platform enabling the implementation of construction inventory based on the remote cooperation of many specialists in the field of, among others: building construction, architecture, civil engineering, photogrammetry, CAD, UAV. This type of cooperation is of particular importance especially in the context of the current epidemiological situation related to COVID-19. The idea of the presented platform fits into the broadly understanding of Building Information Modeling. After introducing the methodology, stages of the inventory and follow-up process carried out within the platform are illustrated and discussed on the basis of a case study. Based on the obtained results it can be concluded that the proposed methodology creates a convenient, efficient and inexpensive tool for massive inspection of building resources in large areas. The inventory is based primarily on high-quality photo and video material obtained from the deck of an unmanned aerial vehicle and the expert knowledge of the inspector conducting the inspection. By combining digital images data (photos, 3D model, orthophotos) with substantive data (facade element classification tables, wear / defect classification tables), we get a platform that allows intuitive access to viewing, classification, editing and analysis of selected data.

Building Condition

An evaluation methodology to estimate the envelope’s degradation level (DL) was developed being after object of adjustment and improvement. The methodology is based on visual survey and in the application of the Failure Mode and Effects Analysis (FMEA) method allied to evaluation scales, aiming to achieve building condition assessment and prioritizing refurbishment interventions. In Portugal, the high buildings number needing refurbishment justified the evolution and improvement of the original methodology of state of conservation assessment of residential buildings at controlled costs. This methodology firstly developed and applied for residential buildings was based on an evaluation scale of eight levels, which was after adjusted to five levels. This simplification aims an easier application of this methodology and provides users with a clear understanding of his features. A summarised evolution of this methodology will be depicted in this paper and will be applied to a heritage building located in the city of Oporto, in Portugal. Beyond the evolution of this buildings conservation assessment methodology, this paper aims to show its usefulness for heritage buildings condition assessment, through the application to a case study.
