Transportation

Kolb Grading has truly made its mark in the transportation industry, participating in flagship projects used by hundreds of millions of travelers each year.

• Airports
  

  Airport construction work requires a significant amount of project coordination and management, as well as team capabilities and skill. Kolb Grading considers the Lambert St. Louis Airport expansion to be one of the top 6 projects ever produced by their firm.

  St. Louis Lambert International Airport - St. Louis, Missouri

  The 2002 St. Louis Lambert Airport expansion created additional runways, access and utility capacity. Kolb led the way by clearing and preparing the 8 million cubic yard site, shoring up the new runway foundations with proper controls using 20,000 ton of rock subgrade stabilization, installing cast and place utility structures, installing security mechanisms on those utility structures and hauling off site debris. Environmental services included seeding and mulching 452 acres and providing erosion control for over 600 acres.

  Serving as General Contractor to the City of St. Louis, Kolb's involvement in the Lambert St. Louis Airport extension encompassed four distinct projects:

  • Grading and paving airport runways 5 and 6
  • Airport north and south temporary bypass (Lindbergh Boulevard)
  • Storm & sanitary sewer cast in place structures
  • Lindbergh Boulevard tunnel backfill

  Tasks included in the Lambert project:

  • Site clearing and grubbing
  • Unsuitable dirt and existing pavement removal and haul
  • Excavation
  • Demolition
  • Rock grade subgrade stabilization
  • Erosion control
  • Sanitary sewer installation
  • 55’ storm sewer cast in place structure
  • Security grate installation on utility structures
  • Security training and employee badging
  • Grading and paving
  • Seeding and sodding

  Coral Creek Airport - Placida, Florida

  The Coral Creek airport expansion included relocating gopher turtles, clearing trees and brush, erosion control measures, grading 200,000 cubic yards of sand and making base out of coral rock saving two million dollars in imported materials. One challenge was that the existing runway had to stay operable during the entire construction phase. The new 1 mile runway project included lighting and striping the tarmac.

• Highways
  

  Kolb has a lengthy history of successful highway construction projects. The company resume includes multiple projects for the Missouri Department of Transportation, including a Hwy 5 lane expansion in Camden County, MO (Lake of the Ozarks), Route 67 outside of Poplar Bluff, MO, and a joint venture constructing Highway 364 in St. Charles County. Moving beyond their home state, Kolb was awarded multiple-project work on I-69 in Indiana and US Routes 71 and 72 as part of the Bella Vista Bypass project in Arkansas.

  Indiana I-69

  The Interstate 69 highway project in Indiana was a complex, significant undertaking requiring plenty of advanced planning, technical know-how, the ability to manage Indiana-based personnel and the ability to manage construction while remaining stewards of the environment. The site was located in southwest Indiana, an area containing multiple karst features and waters of the United States. This required strict water quality management and conservation. The contract required Kolb to perform stage D construction in an effort to preserve wildlife habitat for animals or native protected species with included American bald eagles, Indiana bats and snails.

  • Unsuitable removal and stabilization 40 feet deep
  • Box culverts and piping
  • Building embankment (10 million cubic yards of unclassified excavation; processing materials to a 4 inch minus; 110 foot fills)
  • Processing and segregating shale, sandstone, limestone and fat clay
  • 465,000 square yards of high strength geo-textile
  • 1.1 million linear feet of wick drains
  • Stabilized 600,000 cubic yards of embankment
  • On-site aggregate manufacturing of 200,000 tons
  • Stabilization of sub-grades
  • Erosion control
  • Rip-rap and rock placement
  • Bridgework including 2500 foot long by 80 foot tall substructure
  • 90 foot piles oriented in 30 foot by 60 foot footings
  • All bridgework performed in floodplain surrounded by environmental "Do Not Disturb" wetland restrictions
  • Wildlife preservation

  Missouri Page Avenue Extension

  The Page Avenue Extension project was a collaboration between MoDOT, St. Charles County and local municipalities who teamed together to fund a 10-mile divided highway — also known as Highway 364 — between Interstate 270 in Maryland Heights and Highway 40 (Interstate 64) in Lake Saint Louis. Facets of this multi-decade project included constructing a highway through Creve Coeur park, relocating a lake, bridge construction, utility relocations, design and construction.

  MoDOT used a Design-Build contracting process to have contractor teams compete to win the contracts. The Missouri Highways and Transportation Commission approved the contract on February 6, 2013, awarding the project to the Page Constructors Joint Venture, which included Fred Weber Inc. and Millstone-Bangert Inc (now known as Millstone Weber) along with Kolb Grading and lead designer, Parsons Transportation Group.

• Railroads
  

  Clearing, excavating, stabilizing and grading railroad track beds, along with embankment construction and stabilization, are all within Kolb Grading’s experienced wheelhouse.

  Whether to support road construction or water-based utility projects, the team at Kolb Grading has a significant amount of time, project experience and stories to tell when it comes to bridges and tunnels. They have been built to provide access to trucks to haul contaminants without using public roads; provided a major thoroughfare for traffic under the runways at St. Louis Lambert Airport and provided safe crossing through a storm water runoff.

  Indiana I-69

  Kolb not only excavated and graded the site for a new bridge on I-69, it installed a 2500 foot long, 80 foot tall substructure with 90 foot pilings oriented in 30 foot by 60 foot footings. All of the work done on this project was performed in floodplain surrounded by environmental "Do Not Disturb" wetland restricted areas home to blue line streams and snails.
