Relevant Projects

Carnahan Middle School
Client: William B. Ittner Inc.
Owner: St. Louis Public Schools
Completion Date: June 2002
Const. Value: $8,000,000

ABNA provided site plans for the 6-acre property.  Site elements included walkways and sidewalks, 66 parking spaces, a play area that also provided space for 15 bus slots and a 500’ double wide circular drive for buses, and all topsoiling, seeding, sodding, and fencing.

To prepare the site, an existing 25,000 square foot building will be removed and an HDPE liner will underlie the new 72,000 square foot building. The liner was necessary because the owner and MoDNR were concerned about contamination due to hydrocarbons under the existing building and a portion of the site. This required a slab on grade / grade beam foundation system to accommodate the HDPE liner and buffer system that was designed by the geotechnical consultant under the direction of MoDNR.

Our design team made recommendations on balancing the earthwork to minimize the need to excavate contaminated soil or borrow new material. The elevation for the finished floor sub-grade was then developed based on the grading balance in consideration of site elements such as drainage and pavement and sidewalk cross slopes.

ABNA also created the site demolition plan that considered a phased construction approach to accommodate an accelerated schedule.
 

Pavement Improvement Program
Client: U. City School District
Owner: U. City School District
Completed:  Sep, 1999
Const. Value: $350,000

This project involved preparation of contract plans and specifications for eight (8) elementary school parking lots and playgrounds within the district. ABNA also provided full construction management services including materials testing for the project. This was a fast track project for ABNA as the design, bidding, and construction all had to be completed within a nine-week period.

Existing parking lots were removed, regraded and resurfaced. New parking lots were designed and constructed to support the districts maintenance truck fleet. Drainage design and other utility adjustment were also incorporated in the plans. The design utilized the recycling of the asphalt pavement as fill material for subgrade in areas where the existing subgrade was unstable.

Pagedale City Hall
Client: KWAME Building Group
Owner: City of Pagedale
Completion Date: October 2000
Construction Value: $1,400,000

This design included topographic surveys, site layout, selection of pavement type and thickness, drainage (storm and sanitary), and parking layout design.

The site design and layout included the storm sewer system, detention basins, sanitary sewer system, and existing and proposed utility research and design.  ABNA produced the final civil site plans, site work construction estimates and civil specifications.  ABNA coordinated with MSD, St. Louis County, and other entities to gain approval for these plans at various milestones.

Kim’s Kids Childcare Center
Client: Korte Construction
Owner: Kim’s Kids Inc.
Completion Date: Apr 2002
Const. Value: $1,500,000

ABNA was the civil member of the design build team for this 9000 sq. ft. childcare facility.  The components of the site include the building, playground, parking lot, and a service drive. ABNA was responsible for Design of the nearly 2-acre Site, Utilities, and Public Agency Coordination.  After the initial kickoff meeting, ABNA worked closely with the project Architect to refine the project layout, establish the earthwork balance and suggested finish floor elevations from which final civil and architectural designs were based.  A unique component of the design was a subsurface drainage system for the play are which consists of a geosynthetic fabric, drainage net, and slotted HDPE French drain.

ABNA’s civil site plan consisted of the final grading, paved areas, storm sewer, sanitary sewer, water service, and exterior lighting. The final grading design included the erosion control plans and an earthwork estimate; and the storm sewer design consisted of drainage area maps, plans, profiles, and drainage calculations.  The 500-foot storm sewer collects water from the 20-space parking lot as well as 14 roof drains, which connect directly into the system.  The paved area design provided entrance plans, profiles design of the internal drive and parking striping plans. 

To ensure a quality final product, ABNA completed the utility service connection design, including gas, electric, and telephone; and coordinated between utilities, by addressing any necessary installation sequencing and crossing details.  All submittals were coordinated through the City of St. Louis, St. Louis Metropolitan Sewer District, St. Louis City Water Department, Laclede Gas, Ameren UE, Southwestern Bell Telephone, and St. Louis City Fire Department.

U. City Maintenance Facility
Client: City of University City
Owner: City of University City
Completed: Oct 1999
Const. Value: $50,000

University City hired ABNA to help them upgrade their maintenance and vehicle storage facility.  This project involved expanding the parking area and organizing the parking spaces according to size to maximize space and efficiency. 

The survey crews first obtained information about the layout of the facility including buildings, fencing, and current storage zones.  The engineering department then met with City officials to design a plan that would best fit their needs.
