Pilot Rainwater Harvesting Study Ireland, Liam Mccarton, Sean O'Hogain, Anna Reid, Niamh Mcintyre, Jenny Pender
Conference papers
There are no National Water Quality Standards for Rainwater Harvesting supply in Ireland. The Development Technology Centre (DTC) at the Technological University Dublin was commissioned by the National Rural Water Monitoring Committee in 2005 to assess the feasibility of using rainwater harvesting to supplement treated mains water for non-potable uses. The project involved the design, installation, commissioning and monitoring of rainwater harvesting facilities for rural domestic and agricultural water supply. This paper will present the results from the domestic pilot rwh project. A dual water supply system was designed and installed to use rainwater collected from the roof surface to …
Performance Monitoring Of Cover-Zone Concrete, Niall Holmes, John Mccarter, Malcolm Chrisp, Gerry Starrs, Sreejith Nanukuttan, Lulu Basheer, Niall Holmes, Muhammed Basheer
Performance Monitoring Of Cover-Zone Concrete, Niall Holmes, John Mccarter, Malcolm Chrisp, Gerry Starrs, Sreejith Nanukuttan, Lulu Basheer, Niall Holmes, Muhammed Basheer
Conference papers
The concrete cover-zone is a major factor governing the degradation of concrete structures as it provides the only barrier to aggressive agents which initiate corrosion of the reinforcement. Knowledge of the protective qualities of cover-zone concrete is critical in attempting to make predictions as to the in-service performance of the structure with regard to likely deterioration rates for a particular exposure condition and compliance with specified design life. To this end, a multi-electrode array was used to study the surface 50mm of concrete specimens thereby allowing a detailed picture of the response of the covercrete to the changing environment. In …
Conductivity Sensors To Monitor Cover-Zone Performance, W. J. Mccarter, T. M. Chrisp, G. Starrs, E. Owens, Niall Holmes, L. Basheer, S. V. Nanukuttan, M. Basheer
Conductivity Sensors To Monitor Cover-Zone Performance, W. J. Mccarter, T. M. Chrisp, G. Starrs, E. Owens, Niall Holmes, L. Basheer, S. V. Nanukuttan, M. Basheer
Conference papers
This paper presents developments in the use of an embedded, multi-electrode conductivity sensor to study the response of the concrete cover-zone to environmental action. The sensor enables an evaluation of the temporal and spatial variation of electrical conductivity thereby allowing an integrated assessment of the cover-zone. Conductivity sensors were embedded within concrete samples to study the cover-zone response to cyclic wetting and drying under laboratory conditions. This work was extended to include the use of remote interrogation methods to study samples placed at a marine exposure site and preliminary results are presented.

It is widely recognised that durability of concrete depends on its transport properties, viz. absorption, diffusion and permeability. As concrete cover provides the first line of defence against the ingress of many deleterious substances into the concrete, a measure of its transport properties is vital in assessing its long term performance in the given exposure condition. In new structures the rate of ingress of the deleterious substances could be monitored using array of electrical sensors which are embedded in the cover concrete. For structures which are currently in service, two in situ permeability apparatuses, viz. Autoclam Permeability System (for measuring …
Creating A Software Marketplace For The Sme Community In The Irish Construction Industry, Alan V. Hore, Roger West, Alan Redmond
Creating A Software Marketplace For The Sme Community In The Irish Construction Industry, Alan V. Hore, Roger West, Alan Redmond
Conference papers
The Construction Industry is a sector where Information Communication Technology (ICT) and e-Business are used to a lesser extent than in most other sectors. The high concentration of Small to Medium sized Enterprises (SMEs) in the industry and the typical nature of the service provided, being an on-site and often highly customised service are generally identified as the reason for the low ICT uptake. The majority of Irish companies in the construction sector are SMEs. E-Business has provided the construction SME industry the opportunity to compete globally. The Construction IT Alliance (CITA) has identified a programme that can create a …

The Construction Industry is a sector where ICT and e-business are used to a lesser extent than in most other sectors. The high concentration of SMEs in the construction industry and the typical nature of the service provided in construction, being an on-site and often highly customised service are generally identi-fied as the reason for the low ICT uptake. The majority of Irish companies in the construction sector are SMEs. It is essential that Irish companies become more effective and efficient with eBusiness technologies in order to compete in the global economy. The Construction IT Alliance in Ireland has identified …
Highway Bridge Assessment For Dynamic Interaction With Critical Vehicles, Daniel Cantero, Eugene J. Obrien, Arturo González, Bernard Enright, Cillian Rowley
Highway Bridge Assessment For Dynamic Interaction With Critical Vehicles, Daniel Cantero, Eugene J. Obrien, Arturo González, Bernard Enright, Cillian Rowley
Conference papers
Dynamic vehicle-bridge interaction is often considered for the most common classes of vehicle such as the 5-axle articulated truck. However, the dynamic response of bridges to this type of trucks is quite different to the response to the vehicles more likely to feature in maximum-in-lifetime traffic loading events. This paper focuses on large (>100 tonne) cranes and crane-type vehicles that have been recorded at Weigh-in-Motion sites in Europe. This paper analyses the total bending moment due to these vehicles on short to medium span bridges and compare them to 5- axle articulated trucks. To account for the variability in …
The Future Scenario Of Creating A Digital Sme Community In The Irish Construction Industry, Alan V. Hore, Roger West, Alan Redmond
The Future Scenario Of Creating A Digital Sme Community In The Irish Construction Industry, Alan V. Hore, Roger West, Alan Redmond
Conference papers
The problems associated with the Construction Industry not being able to manage and com-municate electronically product and project data between collaborating firms and within individual companies is compounded by the large number of small companies that have not adopted advanced Information Com-munication Technology (ICT). The typical nature of the service provided in construction, being an on-site and often highly customised service are generally identified as the reason for the low ICT uptake. The majority of Irish companies in the construction sector are Small to Medium sized Enterprises (SMEs). As eBusiness opens up the Irish economy to international competition Irish SMEs …
