The city awards the site through a competitive tender focused on a constraint on the strict total CO\u2082 cap (2,070,000 kg)<\/strong>, so the quality of our proposal depends on how well we manage CO\u2082 and cost across the entire<\/em> combined system, not within a single component.<\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\n Fig. A depiction of the simplest possibility of the Combined System<\/p>\n\n\n\n <\/p>\n\n\n\n To make this integration measurable, we model the project as six linked subsystems and define a small set of parametric inputs that drive the overall outcomes. On the infrastructure side, the bridge length\/position<\/strong> determines the steel truss quantity and directly sets the connected pavement length, which together influence embodied CO\u2082 and cost. On the containment side, the radius of the concrete wall<\/strong> and the height of the cylindrical part<\/strong> scale concrete volume and therefore strongly affect emissions and cost. On the retrofit side, the roof is modeled through deck thickness<\/strong>, substrate thickness<\/strong>, and green roof coverage<\/strong> (meeting at least the 10% requirement), while the timber truss material<\/strong> influences the roof\u2019s structural system and embodied impacts. Finally, the historical masonry behavior is captured through wall bay length<\/strong>, which affects how loads are distributed and where strengthening may be required.<\/p>\n\n\n\n We developed a combined parametric model and ontology for a tender-driven infrastructure proposal where CO\u2082 is the hard constraint,<\/strong> and ROI is the decision metric<\/strong>. By connecting these inputs through a single integrated logic, we can compare design variants consistently and select a solution that performs best against the municipality\u2019s CO\u2082 objective while remaining economically viable.<\/p>\n\n\n\n Our Six Individual Systems<\/a> are:<\/p>\n\n\n\n Steel truss bridge<\/a><\/strong><\/p>\n\n\n\n Perpetual<\/strong> Pavement<\/strong> <\/a><\/p>\n\n\n\n Wood Roof Truss System<\/a><\/strong><\/p>\n\n\n\n Green Roof System<\/a><\/strong><\/p>\n\n\n\n Masonry Wall in Historic Building<\/a><\/strong><\/p>\n\n\n\n Nuclear Containment Building<\/a><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":" Introduction We are general Contractors asked to bid on a design-bid-build project renovating an old historical building and a nuclear containment facility near it.
