摘要

ALBION Drilling Group recently completed the blasting of over 330,000m~3 of rock, 10,000m~2 of pre-split and 2,750m of stitch drilling during phase two of the A1/N1 Newry Bypass road improvement scheme. The works posed various technical difficulties due to the proximity of nearby homes, some of which were as close as 25m, and also by being adjacent to the main Belfast-to-Dublin railway line and the busy Newry bypass. This one-year contract, for Lagan Ferrovial JV, was won after successfully undertaking phase one - Dundalk to Newry - the previous year.
