A SYSTEMATIC APPROACH FOR THE SELECTION OF THE ARCHITECT/ENGINEER PROFESSIONAL IN CONSTRUCTION PROJECTS

Sadi ASSAF/ Mohammad A. HASSANAIN/ Laith HADIDI/ Azfar AMMAN

This paper presents a model for selecting Architect/Engineer (A/E) professionals for construction projects. The model takes into account all relevant criteria considered by the owner. These criteria were identified through a comprehensive literature review, and were then clustered into seven groups, namely firm background; past experience; technical resources; management capabilities; financial stability; quality assurance; and innovation capability. The Analytic Hierarchy Process (AHP) was util(..)

DEVELOPMENT OF SUSTAINABLE ASSESSMENT METHOD AND DESIGN TOOL FOR EXISTING AND TRADITIONAL BUILDINGS IN JORDAN

Rana Tawfiq MATARNEH

In the last ten years, numerous Sustainability Assessment Systems have been developed worldwide to provide construction stakeholders tools that help in achieving better sustainable development. Jordan developed its own Green Building Guideline in 2013 for new buildings but unfortunately, the guideline hasn’t included any criteria for existing or traditional buildings. The main objective of this study is to develop a sustainable Assessment Method for existing and traditional buildings to assist b(..)

COLLABORATIVE HOUSING PERSPECTIVES. DEFINITION, HISTORICAL OVERVIEW AND EXAMPLES

Agata TWARDOCH

This paper is a continuation of the paper entitled “Collaborative Housing Perspectives in Poland. Definition, Historical Overview and Examples” and it describes the possibilities of implementation of collaborative housing in Polish conditions. In the paper, apart from legal constraints, the author also describes the benefits of collaborative housing, because as far as benefits of building homes in the construction group system, co-operative or co-housing seem to be quite well diagnosed for the i(..)

REVIVE TO SURVIVE AND DEVELOP. CITY CENTRES OF SHEFFIELD (U.K.) AND KATOWICE (PL)

Anna Marta WŁODARCZYK/ Michał WŁODARCZYK

In the beginnings of 21 century revitalization by means of public open space planning is becoming more and more popular. The purpose of the paper is to juxtapose (not to compare) two European examples of public open spaces created in areas, which are neglected in urban and landscape way: The revitalized centre of the Sheffield post-industrial steel-city in England and the former coal mine area of the present new Silesian Museum in Katowice, Poland. The empirical and analytical methods were appli(..)

APPLICATION OF THE ANALYTIC HIERARCHY PROCESS (AHP) FOR ACOUSTIC ADAPTATION OF CLASSROOMS

Artur NOWOŚWIAT/ Florentyna SZURMAN

In the paper we put forward a proposition of acoustic adaptation of classrooms based on the analytical hierarchy process (AHP). The main objective of such an adaptation is to increase speech intelligibility aiming to enhance the teaching quality level. The model is based on four main criteria which have impact both on the teaching process and on the adaptation costs. The said criteria comprise reverberation time, speech transmission index STI, financial cost of the adaptation and non-economic co(..)

HYPERBOLIC PARABOLOID (HP) PANTOGRAPHIC STRUCTURE WITH LINER SCISSORS

Arash OSMANI/ Mohammad Reza MATINI/ Yaser SHAHBAZI/ Hossein GOLLABI

A pantograph is a foldable structure which consists of scissor link units. A unit consists of two bars elements which are capable of rotating about their intermediate pivot node. The pantographic structures are generally utilized in flat (like roof), cylindrical (like barrel), and spherical (like dome) deployable structure and they are not used in anticlastic structure like hyperbolic parabolic (HP) structure. The HP surface may form when a convex parabolic goes on the length of concave ones wit(..)

SULFATE RESISTANT CONCRETE WITH ALUMINOSILICATE ADDITIVES

Artem PRYYMACHENKO/ Leonid SHEINICH

The paper observes an improvement of the sulphate resistance of concrete. This was achieved through creation of dense concrete structure with sulphate resistant binder matrix. Series of tests confirms the positive effect after optimizing the sieve line, also in very fine area; reducing the water-cement ratio with superplasticizer on polycarboxylate basis and restriction of the sulphate sensitive clinker. These steps were possible through adding active aluminosilicate mineral additives. They impr(..)

THE SIMULATION OF CORROSION DEGRADATION OF CONCRETE SPECIMEN IN STATIONARY HEAT AND MOISTURE CONDITIONS

Faustyn RECHA/ Tomasz JAŚNIOK/ Tomasz KRYKOWSKI

This paper is focused on the problem of forecasting damage in reinforced concrete specimens as the consequence of chloride corrosion. The performed numerical calculations included time necessary for filling empty pore space and tightening corrosion products in the interfacial transition zone (ITZ) . In those calculations we assumed the formation of distortional strains in the ITZ layer caused by mass increase of corrosion products dependent on corrosion current intensity.

RESEARCH ON THE LIGHTWEIGHT CONCRETE BRIDGE DECK SLABS REINFORCED WITH GFRP COMPOSITE BARS

Agnieszka WIATER

The main goal of the paper is the presentation of research works on static and fatigue behaviour of LWC (lightweight concrete) deck slab reinforced with GFRP (glass fibre reinforced polymer) rebars. The structural LWC with lytag type aggregate has been used for slab casting. The carrying capacity of the slabs as well as fatigue durability have been checked during experimental tests on three full-scale deck slabs. All slabs were 5.2 m long, 1.9 m wide and 0.18 m deep. One- and two-span arrangemen(..)

ECONOMIC ASPECTS OF APPLICATION OF PRETREATMENT SYSTEMS BEFORE GRANULAR ACTIVATED CARBON FILTRATION

Adam GUMIŃSKI/ Marcin KŁOS/ Jolanta GUMIŃSKA

Granular activated carbon (GAC) is used for removing an excessive amount of organic contaminants causing undesirable taste, odour or colour of water, and refractive micropollutants, such as heavy metals or toxic organic compounds. However, adsorption is one of the most expensive unit processes used in treatment and renewal of water. This is due to the high cost of granular active carbon and the necessity of its frequent exchange or regeneration. In the paper the authors present the results of th(..)

OPTIMIZATION OF WINDOW SIZE DESIGN FOR DETACHED HOUSE USING TRNSYS SIMULATIONS AND GENETIC ALGORITHM

Joanna FERDYN-GRYGIEREK/ Krzysztof GRYGIEREK

Heat gains from the sun affect the heat balance of building by reducing the energy demand at certain periods of the year and increasing it at others. Windows, especially the type of glazing, are a determining factor in the successful use of solar gains. The aim of the research presented in the paper is to analyse the effects of the type and size of windows on annual heating and cooling energy consumption considering the energy costs in Polish climate conditions. Additionally the influence of bui(..)

A HIGH-PERFORMANCE COMPUTING (HPC) BASED INTEGRATED MULTITHREADED MODEL PREDICTIVE CONTROL (MPC) FOR WATER SUPPLY NETWORKS

Krzysztof GASKA/ Agnieszka GENEROWICZ/ Izabela ZIMOCH/ Józef CIUŁA/ Zsuzsanna IWANICKA

The article presents the concept of an intelligent system of multithreaded, hierarchical predictive control of water supply and sewage networks using a parallel computational architecture. The predominant element of the proposed control system over other hitherto functioning systems is the element of predicting future events (MPC model). This feature, combined with the self-learning intelligent control system, not only allows you to react to changes in sensor state, but also anticipate these cha(..)

INDOOR ENVIRONMENT QUALITY EVALUATION IN DWELLINGS: A POLISH CASE STUDY

Jan KACZMARCZYK/ Aleksandra LIPCZYŃSKA/ Przemysław KATEUSZ

The indoor environment determines the occupants’ comfort and significantly affects the energy consumed for heating and ventilating the building premises. Therefore, the proper complex thermal diagnostics of existing buildings requires a fair assessment of indoor environment conditions. The method for measuring and assessing the quality of the thermal environment and the quality of the indoor air is demonstrated through the example of two single-family houses and one apartment in a multi-family h(..)
