122 chapter seven ConstruCtability When FRP materials are used for highway infrastructure, there are many things to consider. Unlike the case of conventional materials such as concrete and steel, contractors may not have sufficient information or knowledge of FRP-based construction. The following is a summary of constructability items based on NCHRP Report 609: Recommended Construction Specifications and Process Control Manual for Repair and Retrofit of Concrete Structures Using Bonded FRP Composites (Mirmiran et al. 2008): â¢ Proper scheduling: overtime, double shift, and high demand for machinery. â¢ Compatibility with surrounding environments: challenging weather (e.g., flood or hurricane). â¢ Operation sequence: identification of operational obstacles delaying construction tasks. â¢ Access to construction sites: right-of-way, contractorâs work space, and material storage. â¢ Conflict with the work of others: traffic interference, utility, or other activities occurring in the vicinity of the construction site. â¢ Long-lead products: a plan for securing unusual materials and equipment. â¢ Contract documents: a review of potential ambiguities and inconsistencies; confirmation of erection and construction sequencing. â¢ Construction drawings: confirmation of dimensions, tolerances, legibility, and conformance with specifications. â¢ Community impacts: noise, dust, and unsafe materials. â¢ Government regulations: compliance with established regulations and policies to safeguard the public and others related to the project. â¢ Post-construction accessibility: a review of design documents to check the availability of post- construction activities, such as inspection and maintenance.
