About this file
This is an attachment document containing technical specifications for insulation installation standards applicable to the Lakeland Electric scaffolding and insulation services contract opportunity in Florida. The attachment references the Midwest Insulation Contractors Association (MICA) Book of Commercial and Industrial Insulation Standards and provides two detailed specification tables establishing required insulation thickness requirements for equipment and piping applications across varying temperature ranges and pipe diameters.
Table 1 outlines equipment and piping insulation thickness requirements for heat retention applications spanning temperatures from 70°F to 1200°F, with specifications ranging from single-layer applications requiring 1 inch of insulation on 2-inch diameter piping at the lowest temperature range to multi-layer applications requiring up to 7 inches on pipes greater than 36 inches in diameter at the highest temperature range. Table 2 provides similar specifications for personnel protection insulation, with thickness requirements generally ranging from 1 to 6 inches depending on pipe diameter and operating temperature. These standards establish the technical baseline for all mechanical insulation installation, repair, and maintenance work to be performed at Lakeland Electric's power generation facilities, including the McIntosh Power Plant, Larsen Power Plant, and Winston Peaking Station, ensuring consistency and safety across routine maintenance, outages, capital projects, and emergency response activities under the proposed one-year contract with four optional one-year renewal periods.
