10. Because of the relatively slow speed of construction, even on a high-density tank there is not enough scaffolding work to keep even one man busy doing only scaffolding work. Both the exterior and interior scaffolding on the neck-down tank at Kapuskasing was raised about three times every two weeks by a small crew of mason tenders. Although the evidence is not clear with respect to this point on the Kapuskasing job, on other tanks mason tenders have been assigned to do scaffolding work when they have a bit of free time from their other duties. On the Kapuskasing job a small straight-wall tank was being built at the same time as the high-density tank, and scaffolding went up on both tanks at the same time. Notwithstanding this fact, Mr. Marilley, the President of Tilechem, estimated that if carpenters had been used to install the scaffold frames on both tanks, two carpenters would have been required for three days about every two weeks to do the scaffolding. As it was, the job in question started in mid-May of 1980, with the first scaffold being erected on June 4th. Although the evidence on this point is not very clear, it appears that carpenters were on site during two weeks in July to install wooden forms for the flareout, for about a week in October to do the roof forms for both the small straight-sided tank and the high-density tank, as well as for a few days in between to install timber beams and forms for haunches.
11. Tilechem began operations in 1974. One of its first jobs was another high-density tank in Kapuskasing. In that case, a carpenter, Mr. Joe Carrier, was hired to do the forms. Mr. Carrier advised the company that it was mandatory to have a carpenter on the job, and he was kept on even when not doing the forms. Although the mason tenders did all of the scaffolding while Mr. Carrier worked on the forms, when he was not engaged on form-work. Mr. Carrier installed the scaffolding. Part of the time Mr. Carrier also operated a hoist. Partway through the project. Mr. Carrier was replaced by Mr. E. Plamondon, another carpenter. Mr. Plamondon testified that apart from the forms for the roof, all he did was install and dismantle scaffolding both on the high-density tank and a smaller indoor tank. Mr. Plamondon admitted that at times he would be doing nothing for a half hour or an hour as he waited for a mason tender to bring him scaffolding frames to put in place. Mr. Plamondon was on the job for five weeks. As we calculate it, he put in the equivalent of, at most, eleven days doing scaffolding work, and did nothing for the rest of the time. Tilechem also constructed a high-density tank in Thunder Bay in 1980. All of the scaffolding on this job was done by mason tenders. Tilechem has done a number of smaller tanks in Ontario, and for all of them has used only mason tenders for the scaffolding. On the project giving rise to this complaint, only mason tenders were assigned to do the scaffolding.
12. Two other firms are active in the construction of unit masonry acid resistant tanks in Northern Ontario, namely, Dante Gasparotto Ltd. ("Gasparotto") and Canadian Stebbins Engineering Manufacturing Co. Limited ("Stebbins"). Gasparotto is based in Thunder Bay. The firm employs carpenters carpenters to build forms and similar work. Gasparotto's consistent practice has been to assign all tubular metal scaffolding, including the tubular metal scaffolding on a number of high-density neck-down tanks, to mason tenders belonging to the Labourers' union.
13. The Stebbins firm is based in Montreal. It is by far the largest firm of its kind in Canada. Prior to 1974, the firm was the only one active in Northern Ontario in the construction of unit masonry acid resistant tanks. Prior to 1971, the company appears not to have had any set policy with respect to the erection of tubular metal scaffolding. The evidence before us indicates that prior to that time almost all tubular metal scaffolding on the firm's projects was either assigned to mason tenders belonging to the Labourers' union, or it was done by labourers in the employ of the various mills who belonged to the Lumber and Sawmill Workers' Union. Since 1971, official company policy has been to assign tubular metal scaffolding to members of Labourers' Local 607.
14. Evidence was tendered with respect to approximately twenty projects where Stebbins had built unit masonry acid resistant vessels in the geographic area under consideration. Except for the three instances more specifically referred to below where continued on page 27
