Pangea Engineering and Surveying, LLC is employed to provide surveying and civil engineering design services for the 550-feet of stream bank and storm channel improvements associated with the extension of an existing 66-inch storm sewer that discharges into a large creek that traverses through the Laclede Gas Company’s – Shrewsbury Yard to its confluence with Deer Creek. Due to changes in the topography and improvements to the areas adjacent to the banks, the creek is in a critical erosive state and is presently downcutting to such a degree that an existing 7-horseshoe shaped concrete combined sewer is now exposed in the bottom of the creek. Pangea provided detailed Topographic, and property Strip Map Surveying Services for this project in extremely difficult terrain within the City of Shrewsbury Kirkwood, Missouri. Pangea is performing the civil engineering design of the storm sewer extension as well as environmentally sensitive improvements for creek bank and channel bottom improvements from the end of the storm sewer to the confluence with Deer Creek.

Pangea Engineering and Surveying, LLC as the prime consultant is performing surveying and civil engineering design services to provide Topographic, property Strip Map, and Easement Preparation Surveying Services for the Providence Place Sanitary Relief Project (MSD 10549), located within the City of Chesterfield, St. Louis County and with an approximate length of 3300-feet. Pangea established horizontal and vertical control monuments over the entire length of this project, extended secondary control into the areas as needed for additional survey. The Pangea project Team is performing the Civil Engineering Design for this complicated sanitary relief project. This project requires detailed coordination with USACE for the impact to existing wetlands and floodplain, as well as coordination with each of the local utility companies for work adjacent to existing utility lines, and coordination with St. Louis County and the local neighborhood association for construction of the proposed sanitary relief sewer in the public rights-of-way and private streets, respectively.

Pangea Engineering and Surveying, LLC is part of the Architectural/Engineering team performing improvement designs for the St. Louis Zoo Project listed above. This project consists of one housing facility and three separate exhibit spaces in the Rivers Edge portion of the St. Louis Zoo. Design services include the horizontal and vertical alignment of a service road, new walks, ramps, sheet pile and modular block retaining walls, site drainage, sanitary sewer lateral systems, grading of the exhibit spaces, specialty details for misting stations, gunite (shotcrete) structural rock formations, reinforced concrete trash compactor enclosures, and miscellaneous utility relocations in the existing space to facility the new facility. Due to the confined nature of the site, detailed attention to existing walks, high block and gunite/shotcrete walls, landscaping and utilities is a critical component of the design.

The 489-D Coal Pile Runoff Basin (CPRB), 484-10D Waste Oil Facility (WOF), and D-006 Outfall were all portions of the D-Area Powerhouse subunit located at the Department of Energy’s Savannah River Site in Aiken, SC to be closed per the scope of this project. Pangea was awarded a design/build contract from Savannah River Nuclear Solutions which required the design and removal of contaminated sediments at the D-006 Outfall, design and removal of contaminated soils at the 484-10D Waste Oil Facility, design and resizing of the Coal Storage Area with accompanying stormwater runoff work, design and closure of the northern 25% of the Coal Pile Runoff Basin with consolidation of contaminated material under a 2 foot soil cover over the closed northern portion of the CPRB. The 484-D Powerhouse remained operational during the project, which required coordination to minimize disturbance of coal delivery and movements. This project was performed entirely in-house by Pangea.

Pangea Engineering and Surveying, LLC, as a subconsultant to CH2M HILL, on this important City of St. Louis project, provided property & topographic surveys and Civil Engineering design services for the proposed pavement, walks, signal, striping, and landscape improvements for the 3,200 feet of Kingshighway Boulevard from Bircher Avenue, at I-70, north to West Florissant, within the City of St. Louis.

Pangea Engineering and Surveying performed the following:

• Established project horizontal and vertical control monuments
• Topographic surveys
• Right-of-Way / Property surveys along all streets and alleys
• Engineering design services for ADA compliant walks, ramps and curb cuts along Kingshighway. This work also included protected crosswalks at intersections at the nose of the landscaped median of Kingshighway and mid-block cut-through walks across the median. All designs of the curb ramps and subsequent sidewalks were based on the design parameters of the ADA and the publication “Public Rights-of-Way Access Advisory Committee, Accessible Public Rights-of-Way, Planning and Designing for Alterations”

Pangea Engineering and Surveying, LLC was employed by the National Geospatial-Intelligence Agency in the City of St. Louis, Missouri to provide surveying and design services to two separate sections of the historic stone wall surrounding the NGA’s south St. Louis City facility. Each of the two sections of historic stone wall and site improvements was approximately 1025’ long. Pangea performed full topographic surveys of the wall area, including streets, parking, lawns, and utilities. Site infrastructure improvements consisted of the design of new parking, streets, curbing and sidewalks and sub-drainage/foundation drains for the areas on both sides of each of the walls. Structural improvement designs included stone and stone cap removal and replacement, tuck pointing, and pier/foundation design for construction. Security improvement designs included new security fencing on top of and gates at the drive entrances to the facility. All wall and security improvements, whether structural or visual, had to meet the requirements of the Missouri Department of Natural Resources, State Historic Preservations Office.
