Incorporating historical and modern elements.
Hotel Saint Vincent was a dynamic undertaking that combined historic renovation with new hospitality construction. For Impetus’ Infrastructure Team, it meant weaving together the hotel’s basic infrastructure needs—sewer, water (domestic and fire), storm drainage, earthwork, paving, and base course—with green infrastructure components that complement the building’s historical design. Engaged as the Design-Build contractor, the team worked with the client and Pace Engineering to create a plan that would incorporate historical and modern elements within budgetary considerations. With our expertise in stormwater retention, historic renovation, and hospitality infrastructure, we created a cost-effective strategy that leveraged the client’s vision with the legacy challenges of the building and the city’s permitting requirements.
A jewel of green infrastructure.
Old buildings come with old foundations. Turning a century-old orphanage, with shallow infrastructure, into a hotel meant putting every square foot into use. To create the central jewel of the hotel’s green infrastructure feature, a complex yet shallow stormwater retention system was installed, with its components touching every external surface of the property. Permeable paving systems—gravel pavers, porous brick, and more—were incorporated into the grotto, pool, and walkway areas to collect rain and direct it down to perforated piping. Rainwater would then flow through a connection under the building and filter into a stone strata in the parking lot before draining into the city system. This combination of aesthetically-aligned elements with rainwater routing created 30,000 cubic feet of stormwater retention that merged perfectly with the hotel’s outdoor design. Most importantly, it met crucial surface water reduction needs without overburdening the city’s rainwater collection system.
