Preconstruction

ICC has extensive experience offering preconstruction services to architects, engineers and project owners. We put the expertise and experience of our project managers, superintendents and estimators to work, collaborating with your team to further define project scope, constructability, phasing, schedule and costs as early in the process as possible to meet project requirements.


ICC Preconstruction Capabilities In Action

CASE IN POINT: JACOBS ENGINEERING

More and more clients are finding the benefit in including experienced contractors on the design team to assist in preconstruction and constructability reviews. Jacobs Engineering engaged ICC to assist with preconstruction on a partial bridge reconstruction for one of the firm’s rail clients— our involvement ultimately resulted in significant project cost savings.

A COST-SAVING SOLUTION TO A PROBLEM WE’VE SEEN BEFORE

The project centered on one of the abutments that was failing on the existing bridge. The original design concept included a new pier in front of the existing abutment and a new abutment behind it. The original concept also required modification of the existing steel girder span and the addition of a new precast span.

During our analysis of the initial design concept, we were able to draw from our extensive experience to suggest an alternative solution we had seen previously for this very condition.

Our proposed solution was to place the new pier in front of the existing abutment and install a new abutment with wing walls tying into the existing structure, then backfill and bury the existing abutment with flowable fill and granular materials. This concept eliminated a pier structure through the use of drilled shafts, structural excavation and a precast span, reducing the total track outage window and saving more than $100,000 in project costs. Our solution was incorporated into the final design.

OUR SCOPE OF WORK
  • Existing document review.
  • Comment on constructability of initial design concept including reviewing existing utility conflicts, access points, and lay down areas.
  • Create a high level schedule for the repair work. • Analyze track outage windows.
  • Create a budget for the work.
