STATE OF THE ART WAREHOUSE, 320 WILSON AVENUE, NORWALK, CT

TURNING UNDERUTILIZED PROPERTY INTO MODERN WAREHOUSE SPACE

The site of this proposed 45,800 square foot industrial warehouse structure has highly varied soil conditions resulting from its natural setting and development history. Design and construction addressed the mixed subsurface conditions from shallow bedrock to thick miscellaneous fill over organic silt and deep glacio-fluvial deposits. The site has a history of industrial and manufacturing land use. Most of the eastern part of the site was originally occupied by open water and salt marshes. The initial site development was construction of the Wilson Point Branch Railroad in the 1800s. The railroad was positioned between the rock outcropped hill on the westernmost portion of the site and the former salt marshes to the east.

STATE OF THE ART WAREHOUSE, 320 WILSON AVENUE, NORWALK, CT

The development consists of a modern 45,800 square foot industrial warehouse structure ideally located near I-95. To reach proposed grades, seven to ten feet of filling was required to raise the east portion of the site to building slab elevation. Thirty feet of rock and earth excavation was also required to bring the west portion of the site down to proposed grades. A retaining wall was constructed around the eastern portion of the site to accommodate the difference between the proposed site grades and existing ground surface on the adjoining properties. The weight of the fill material and building presented a challenge due to the increase of stress in the underlying soil, compressibility of underlying soils, and variable composition and thickness of existing surficial fill. GEODesign designed a preload and surcharge fill to “pre-settle” the site and permit use of normal shallow foundations. This design avoided the expense of other ground improvement methods or pile foundations.

We also assisted in the due diligence process before purchase by reviewing historic environmental reports for the site and adjoining properties. Our environmental professionals assisted our client as a prospective purchaser by coordinating with the buyer’s and seller’s attorneys and environmental consultant. We reviewed environmental testing results and observed environmental restoration of subsoils.
