   4. Gel coating shall be Revchem of specified color.
      
2. Construction
   Architectural parts shall be fabricated by the hand layup or spray laminate method using suitable molds to attain the desired surface finish. The finished reinforced plastic material shall be not less than 5/32" thick and thicker in those areas requiring additional structural strength.
   Where ribs or stiffeners are to be fastened to liner sections by spray laminating over premolded forms, the stiffeners or ribs shall be located and spray laminated into position before the section to which they are to be attached has passed the gel state of curing, and the finished joint shall be strong and durable.

1. Prior to planter liner fabrication, the contractor shall verify as-built dimensions of planter receptacles ensure proper size, fit and quantity required. 1
   
2. Unless liners have drainage fittings as in 2.3.A, drainage holes to be located and made by contractor in the field to fit to drainage system.
   

1. Install planter liners to allow for easy removal if necessary.
   
2. Provide continuous basal support.
   
3. Install liners level to permit adequate drainage and irrigation.

1. Field verification of actual planter receptacle size is frequently overlooked by the contractor, and can lead to delays and additional cost if neglected.
