Schedule & Delay Analysis

Claims involving alterations in the execution times of the different tasks or delays in meeting the milestones and / or completing the work are probably the most frequent and also the most difficult to resolve.

Inspired by this reality, INTELATINAGP‘s members have trained and acquired valuable and extensive experience in the use of the most modern techniques that have been developed for the analysis of impacts on schedules. These techniques are based on the Critical Path Method (CPM) and are recommended internationally by the UK’s Society of Construction Law (Delay and Disruption Protocol) and by the American Association of Cost Engineering – AACE (Recommended Practice No. 29R- 03 Forensic Schedule Analysis), for example:

  • As-Planned vs As Built
  • Impacted As-Planned
  • As-Built but for
  • Collapsed As-Built
  • Windows Analysis

The analysis process with these tools allows determining the impacts of the facts on the critical activities and on the “almost critical” in which the free float has been consumed. Delays, accelerations and the effects of productivity and performance disturbances are analyzed together.

These techniques and their variations or adaptations, selected and used appropriately, make it possible to distinguish between independent and concurrent delays and thus draw up a matrix of responsibilities for each party. The presence of concurrent delays often generates the sharpest controversies, with cross-accusations between the parties.

Disruption – Serious Alterations in Productivity and Efficiency

Generally, in projects where events that affect their development (frequent or significant changes, stoppages, accelerations, etc.) occur, productivity is seriously affected, thereby increasing project costs.

Claims for loss of productivity are also very frequent and difficult to prove. The most common causes are:

  • Numerous and frequent changes in projects and working methods.
  • Obligation to increase the number of workers and overtime.
  • Congestion, overlap, and unanticipated interference between different tasks.
  • Changes in the planned sequences of work.
  • Adverse weather conditions.

InterlatinaGP has participated in numerous cases in which it was necessary to determine the causes that led to the loss of yields, isolate them, measure them and evaluate their economic consequences. Various techniques are used based on information from the project itself, on the company’s background and on industry data, following the recommendations of the American Association of Cost Engineering – AACE (Recommended Practice No. 25R-03 «Estimating lost labor productivity in construction claims.”

Evaluation of Additional Costs

InterlatinaGP has extensive training in budgeting, cost registration and monitoring, cost control, accounting and other economic and financial aspects involved in a project and in the construction company, thus ensuring the correct and complete evaluation of additional costs and damages that arise as a consequence of variations in construction time, productivity, quantities of work, etc., including indirect costs, general expenses, financial costs, profit, etc.
