Abstract
ABSTRACTGeotechnical mapping of urban environments is usually constrained by the scarcity of outcrops during fieldwork. Such is the case of Avilés, a coastal Spanish city that has been heavily industrialized since the middle of the last century. This research approaches the study of its urban subsoil through the development of a Geographical Information Systems-based relational database containing thousands of unpublished ground data, partially extracted from geotechnical reports. This allowed analysing the distribution and changes of thickness of the superficial deposits and lithostratigraphic formations as well as the evaluation of their main geotechnical properties. Thus, 14 geotechnical units were differentiated (hierarchically displayed in three categories) depending on lithological, geotechnical and constructive criteria. As a result, this investigation provides a geo-engineering map at scale 1:25,000.

Summary
Geotechnical mapping of urban environments is challenging, mainly due to the scarcity of outcrops. Recent engineering geological maps at urban environments are based on ground databases, which are generally manipulated using GIS software (Chaminé et al, 2016; Culshaw & Northmore, 2015; El May, Dlala, & Chenini, 2010; Faccini, Robbiano, Roccati, & Angelini, 2012; Forster, Lawrence, Highley, Cheney, & Arrick, 2004; Masoud, 2016; Merritt & Whitbread, 2007; Oliveira, Gomes, & Guimarães, 2009; Zuquette, Pejon, & Dos Santos Collares, 2004), and this methodology seems to be fully consolidated to approach these environments subsoil studies. The first geotechnical map of Avilés was published within the National Geotechnical Maps at 1:200,000 scale (Julivert, Truyols, Marcos, & Arboleya, 1972) which included a brief geotechnical synthesis. Other studies about specific geotechnical aspects have been subsequently published such as the characterization of residual soils (Díaz-Díaz, Arias, López-Fernández, & Pando, 2014; Díaz-Díaz, Omer, & Arias, 2016; Torres Alonso & Gutiérrez Claverol, 2006)
