Abstract

Summary Although Britain is relatively rich in natural aggregate reserves, planning approvals to develop new quarries are running at about half the rate of aggregate extraction. This paper reports on a property study of crushed concrete and demolition debris with a view to using these materials in construction instead of natural aggregate. One of the objects of the research, on which this paper reports, was to accumulate data which would be a basis for the production of a British Standard for recycled materials in construction. Document type: Part of book or chapter of book

Abstract

As part of a building decommissioning and demolition program at Aberdeen Proving Ground, a detailed inspection of each target building is being conducted in order to characterize and describe the state of the building as it currently exists and to identify areas potentially contaminated with toxic or other hazardous substances. Room surfaces, drains and sumps, remaining equipment, and such associated exterior aboveground and underground appurtenances as tanks and pipelines are among the features, generically termed compartments, that may be potentially contaminated. Detailed drawings are being prepared for each building to illustrate the existing structure. This report presents the results of the inspection of Building E5375 in the Edgewood/Canal Creek area of Aberdeen Proving Ground. Nine potentially contaminated compartments were identified in this building and its vicinity. Document type: Report

Detailed drawings are prepared to illustrate the existing structure of each building. This report presents the results of the inspection of building E5190 in the Edgewood/Canal Creek area of Aberdeen Proving Ground. This building houses a 10,000-gal tank formerly used to store xylene. Eleven potentially contaminated compartments were identified in this building and its vicinity. Document type: Report

Abstract

Post-earthquake reconstruction of the historic city Centre of L’Aquila, Italy, can be considered as the largest building site now under operation in Europe. The earthquake that hit the city of L’Aquila on the 6th April 2009 generated a so-called seismic crater that comprises 56 municipalities and concerns an area of almost 2.400 Km2. The earthquake of 2009 destroyed or severely damaged all historic buildings of the city Centre. Nowadays, in 2020 there are more than 8.000 completed construction projects that produced almost 4.000.000 t of removed rubble. The reconstruction process of L’Aquila has been soon defined as “the biggest construction site of Europe”. This experience of managing a huge number of construction projects in the same town highlighted the need of a multi-project coordination of the re-construction activities, and a central co-ordination office has been created. Problems concerning the co-ordination of many construction sites that are located very close to each-other are many and are related to the organization and sharing of different resources: space for tower cranes, access routes for vehicles, space for temporary scaffoldings and space for debris storage and disposal. The programme management of these production resources needs to be based on a General Management plan that is proposed. In particular, the problem of rubble production, transport and storage has been addressed in the plan proposition. In fact, the production, transportation and storage of rubble produced by construction operations can be considered one of the main criteria of the multi-project optimization process needed for the co-ordination of the city reconstruction. As a pilot study, a simulation of project co-ordination of an urban area that includes eleven building blocks under re-construction has been performed with the traditional resource levelling procedure. Therefore, the reconstruction programme schedule of the area has been optimized considering the process constraints due to quantitative limits of rubble transportation and disposal.
