Site clearing was tackled early on with little difficulty. However, as the main construction got into full swing some eight months later, more significant problems began to appear. The change in production train specification made it necessary to add another five feet to the length of the new building. This was only discovered when holding-down bolts for the new trend were laid out on site, long after the perimeter foundations had been poured. The catalogue descriptions and specifications for other equipment selected were similarly not received and reviewed until after the foundations had been poured.
Leadbetter was not entirely satisfied with the installation of the mechanical equipment for the dust-free paint shop. As a registered mechanical engineer, he knew that the specifications governed the quality of equipment, workmanship and performance. However, since these documents had still not been formally approved, he was loath to discuss the matter with Ivar Kontrak. Instead, he dealt directly with Amos Dent of Tinknockers Associates, the mechanical sub-contractor. This led to strained relations on the site.
Another difficulty arose with the paint shop because the local inspection authority insisted that the surplus paint disposal arrangements be upgraded to meet the latest environmental standards.
