-Materials pertaining to a site inspection performed by Markus Casey at a site adjacent to Kilsaran Concrete's quarry at Bunaterin, just west of the village of Mucklagh near Tullamore. Casey found no clear evidence of archaeological sites that would be disturbed by the expansion of the quarry.

-Report (.doc format) written by Markus Casey for Tom O'Keeffe. Casey was commissioned to inspect a site in Lydacan, Claregalway O'Keeffe wished to build upon. The site formerly incorporated a late medieval tower house (Lydacan House) that was largely demolished in 1992 by a previous landowner, and had been annotated as early as 1778 as the site of a ruined castle, which the current landowner was unaware of and created a delay in the development of the site. Casey recommends a programme of mitigatory measures to mitigate any possible interference with medieval remains that the proposed development might incur (September 2001, 15pp; see P164/3/8/1 for related materials);
-Archaeological assessment (.doc format) written by Markus Casey of No. 20, Long Walk, Galway, which deemed the site to be archaeologically resolved (20 March 2002, 3pp).
