INSTRUCTIONS TO AUTHORS

• Scope an policy
• Form and preparation of manuscripts
• Sending of manuscripts

Obras y Proyectos invites to publish for the contribution of the development of Civil Engineering in any of its branches. The traditional branches of Civil Engineering considered are Structures, Geotechnics, Hydraulics, Transport and Construction. Nevertheless, inside each of these branches there are other subdivisions which are also welcome such as Earthquake Engineering, Rock Mechanics, Hydrology, Coastal and Port Engineering, Highways and Bridge Engineering and Material Engineering. Civil Engineering interacts increasingly with other disciplines and for that reason articles covering Environmental, Geological, Mining, Computing and Technological topics, among others, are also considered.
       
Articles are revised by at least two reviewers outside the editorial committee and the Department of Civil Engineering of the Catholic University of Concepción.

From observations of the external reviewers, an article can be accepted, accepted with observations or rejected. In the second case, introduction of changes to satisfy the requirements pointed out by the external reviewers are asked. In any of the above three cases, authors are informed about the review results and the changes needed. Authors do not know who reviewed the articles and there is no contact between authors and reviewers. The edition process takes the right of introducing minor changes in the article to comply with editorial requirements of quality and clarity.

1. The articles sent should be original and not have been published before nor be in a revision process for other publication. Once the article is received complying with points detailed below, it will be sent to external reviewers, experts in the specific subject of the article. The authors are responsible for recognising any conflict of interest which might bias the work, for example, naming sources of funding and support.
       
2. Articles should not have more than 8000 words. No specific format is obligatory, but it is suggested the use of letter size 12, Verdana letter type and double spacing. It is required to write with clarity, which means to follow a logical sequence of what is written. It is also needed clear figures, plots, tables and pictures.
   
   
3. Articles should include in the first page the title, name and surname of the authors as well as the affiliation, postal and electronic address of all the authors. The title has to be written in Spanish and English.
   
   
4. The abstract should not exceed more than 250 words and should address the key points of the articles and gives and brief resume of the application and main article conclusion. The abstract has to be a correct translation from the Spanish. Keywords have to be included in English and Spanish.
   
   
5. The references have to be complete and correct. The references cited in the text, figures and tables have to be included in the reference list at the end of the article and vice versa. In the text, figures and tables, references should be written as Martínez (2008) or (Goodell and Warren, 2006). For more than two authors it should be cited as (Van Abeelen et al., 2008). If the same authors cited have more than one publication the same year, it should be used 2010a, 2010b, etc. The style of the references should consider the following examples:

6. Tables and formulae (equations) should be numbered sequentially in the same order as they appear in the text, with Arabic numbers and referring to them as: Table 1, Table 2, formula (1), formula (2)...etc., as appropriate. Tables should not repeat results presented in plots and the titles for tables put above the table. The unit system accepted is the International System IS.
   
   
7. Figures can include plots, sketches and diagrams. Figures should be sent ready for publication, laser print quality. Photographies and pictures should also be of high quality. Sequentially numbered as Figure 1, Figure 2 or Photography 1, Photography 2, etc. and the title for the figure put below the figure. Figures have to be mentioned in the text before they appear.
   
   
8. Opinions stated in the articles published in Obras y Proyectos are exclusive responsibility of the authors and they do not reflect necessarily the point of views of the Department of Civil Engineering of the Catholic University of Concepción.
   
   
9. The submission of an article to Obras y Proyectos implicates that the authors accept to transfer the authors’ rights of their articles to the Editorial only if the article is accepted for publication. The copyrights cover the exclusive rights for the reproduction and distribution of the article, including reprints, photographic reproductions, microfilms, scanning or any other similar preproduction method as well as translations. Permissions to use figures which do not belong to the authors have to be obtained by the authors before submitting the article.

The articles can be written in English and Spanish and should be send in electronic version in Word format .doc (not .docx), to the Editor Dr. Felipe Villalobos through an electronic mail to oyp@ucsc.cl (preferred) or in a CD or DVD through postal mail to the Department of Civil Engineering, Catholic University of Concepción, Alonso de Ribera 2850, Casilla 297, Concepción, Chile.
