The document provides details on the construction methodology for expanding the infrastructure of the Ruwais Housing Complex Phase IV project. It includes scopes of work, project milestones, organization structure, phasing plans for building and villa sites, work breakdown structure, execution plans for infrastructure networks and structures, and lists of major materials. The infrastructure expansion involves networks for water, sewerage, electricity, gas, telecom, roads and landscaping across building and villa sites, as well as structures like the SNG plant, water reservoirs and pumping stations, electrical substation, and sewerage lifting stations. The project is scheduled to be completed in phases by 2022.
