Wightman Park Green Infrastructure Project

Sci-Tek provided surveying, geotechnical engineering and construction inspection services for the Pittsburgh Water and Sewer Authority (PWSA) Wightman Park Green Infrastructure Project. Wightman Park, located in Pittsburgh's Squirrel Hill neighborhood, was rehabilitated to create a safer, cleaner, greener, and more accessible space. The area adjacent to Wightman Park has historically experienced surface flooding and basement backups in localized areas due to limited capacity within the existing combined sewer system.  The construction of selected green infrastructure improvements is intended to enhance the performance of the combined sewer system and to help reduce basement flooding.  As a subconsultant to PWSA’s lead design firm, Ethos Collaborative, and PWSA’s Construction Manager Hatch, Sci-Tek provided the following services:

Surveying

• An existing conditions survey including all details of the streets extending to the back of sidewalks; details within ten feet of the right-of-way line; underground utility flags or paint markings; and data on sewer rim/catch basin grate and invert elevations, pipe diameters and materials, and flow directions.
• A topographic survey drawing to show the details of the features surveyed

Geotechnical Subsurface Exploration

• Test borings and borehole infiltration tests for proposed green stormwater infrastructure facilities
• A geotechnical report with conclusions and recommendations

Construction Management and Construction Inspection (CM/CI)

• Daily Field Reports
• Daily photos
• Contractor observation to document construction in accordance with plans and specifications
