TERRA engineered the excavation and backfill work for the initial preparation of the site. In coordination with the environmental and geotechnical engineer of record, TERRA provided site preparation construction documents that detailed the demolition, excavations, and backfill scope of work to prepare the site for the building foundation placement and site work. The site preparation scope of work for the Fire Engine #16 site required the removal of large concrete foundations that remained buried onsite from previous development. TERRA designed and engineered construction plans for the removal of the existing foundations with no impact to the right of way and adjacent developments. In addition to the removal of concrete, existing utilities, including sewer, were removed and capped.
TERRA engineered the removal and replacement of the existing bituminous Chicago Alley adjacent to the site. Engineering of the new concrete alley grading and drainage was provided to meet the latest Chicago requirements. The alley design was permitted through the Chicago Department of Transportation. The building phase of the E16 project involved a new fire station building and site work including a permeable paver parking lot, heavy duty concrete access drive, stormwater detention, and utilities. The majority of the stormwater detention for the site is accommodated in the permeable paver parking lot. The porous aggregate base of the permeable pavers detains the required 100-year storm volume. The stormwater detention design was permitted through the City of Chicago’s Department of Water Management.
