With
each day's delay resulting in mounting financial
losses, specialist blasters Pieter Uittenboogaard
of Zandaam, Netherlands and Yeo Boon Chin with Orientech
Engineering of Bedong, Malaysia were contracted
to remove the concrete with explosives. Precise
calculations were absolutely critical, as any cracks
occurring in the attached blinding layer of concrete
- or worse, any shifting of the piles below - would
cause a far larger problem.
As
an added complication, political conditions in the
remote region of the country made conventional explosives
impossible to secure, and the team was forced to
perform the task using a combination of ammonium
nitrate and fuel oil (ANFO). Yet another complication
related to the remote location was the lack of drilling
equipment, and laborers were forced to hand-drill
each blast hole using antiquated drills with dull,
badly over-used attachments. As Uittenboogaard stated
on site, "We have not worked in this way for
30 years, but we must use the tools we have to complete
the job."
