"ASCE uses the author-date method for in-text references, whereby the source reads as the last names of the authors, then the year (e.g., Smith 2004 or Smith and Jones 2004). A References section must be included that lists all references alphabetically by last name of the first author. References must be published works only. [...] Likewise, all references included in the References section must be cited in the text" (Publishing in ASCE Journals 2014).
