Some of our successes include:

Prepare a cost-loaded and resource-loaded CPM baseline schedule and monthly schedule updates for a general contractor at a multi-phased U.S. Federal Courthouse under the GSA scheduling specification. TDF’s services also include “Monte Carlo” simulations to evaluate construction sequences and “what-if” scenarios.

Testify as a schedule expert in mediation for a transit authority on a $217 million design-build rail extension project. TDF used the windows method in the detailed schedule analysis that considered impacts such as weather, access and utility issues, productivity, design changes and contractor delays.

Testify as a schedule expert in state court for a sitework contractor on a $10 million home improvement warehouse retail outlet. The general contractor terminated the sitework contractor, yet the contractor failed to consider the owner’s re-design of underground stormwater piping and its own failure to coordinate the work.

Prepare an evaluation of the integrity and feasibility of a baseline schedule for an EPC contractor at a nuclear medical isotope facility. 

Prepare a CPM completion schedule, monthly updates, and a preliminary delay analysis for a general contractor on a $36 million condominium project. Delays were caused by differing site conditions and numerous design changes. Our involvement in the on-site joint scheduling meetings assisted the contractor in avoiding litigation.

Assist a general contractor with strategic demonstrative graphics for two separate projects: an office/retail project and a Library/Theater project. Our graphics were used by the contractor to illustrate a cause and effect relationship between the numerous owner changes and the related schedule activities that delayed occupancy.

Assist a mechanical contractor prepare a productivity study at an underground water distribution and sewer collection system. The contractor faced differing site conditions related to unexpected quantities of rock and excessive utilities during construction. TDF used a measured mile approach to quantify damages and delays.

Assist a mechanical contractor prepare a delay analysis at an underground steam distribution project. The contractor encountered numerous owner disruptions related to access that required the contractor to revise its planned sequences at an active college campus.

Testify as a schedule expert in mediation for a transit authority on a $90 million train station. The contractor failed to submit timely monthly updates ultimately leading to lack of progress on critical activities and disruption across a project that included 8 inter-related milestones.

Prepare a CPM baseline schedule, monthly updates, delay analysis and testimony as a schedule expert for a general contractor in deposition and arbitration hearings on a $6 million retail and office project. TDF used a windows method to prove delays that included differing site conditions due to poor soils, weather and untimely owner decisions. 

Testify as a schedule expert in deposition and arbitration hearings for a global EPC contractor on a $181 million coke making facility. The project schedule included a planned early completion that was delayed due to differing site conditions caused by excessive water infiltration. TDF used a windows methodology to demonstrate the contractor’s mitigation efforts to meet the early completion date.

Testify as a schedule expert in United States District Court for the Southern District of Indiana, Indianapolis Division for a billion dollar per year owner on a new grain processing plant. The case involved the defense of a wrongful termination claim submitted by one of the mechanical contractors. TDF used a windows methodology to demonstrate the contractor’s delays and performed a productivity study to justify the termination. 

Testify as a schedule expert in state court for a prime contractor performing the general contracting work at a new $10 million school. The contractor was wrongfully terminated by the school district under a multi-prime project delivery system. The school district’s termination decision failed to consider its own duty to coordinate the work as required by contract. The prime general contactor’s critical path work failed to progress due to delays caused by numerous owner changes and precedent mechanical activities.
