Abstract

Data centers are IT infrastructure that needs to be precisely scheduled and coordinated. Significant
financial losses and operational failures may result from building delays. Stakeholders can assign
blame and comprehend the reasons behind delays with the aid of forensic delay analysis. Because of
their unique approaches and legal acceptability, TSWA, and IAPA are commonly used among the many
strategies. These methods provide various ways to analyze project schedules and pinpoint significant
delays. IAPA looks at how certain events affect project completion, whereas TSWA compares planned
and actual timetables. The complexity of the project, the documentation that is accessible, and the
particular demands of the dispute resolution procedure all play a role in the decision between various
approaches. Among the various delay analysis methodologies available, Time Slice Window Analysis
(TSWA) and Impacted As-Planned Analysis (IAPA) are two of the most commonly applied techniques,
largely due to their methodological rigor and acceptance in legal and arbitration settings. TSWA
involves a detailed comparison between planned and actual project schedules across defined time
periods, allowing analysts to assess delay impacts as the project progresses. This method is particularly
useful for complex projects with extensive schedule updates and reliable contemporaneous records. In
contrast, IAPA evaluates the effect of specific delay events by inserting them into the original baseline
schedule to determine their impact on the planned completion date. This approach is often applied when
contemporaneous updates are limited but a robust baseline program exists. The selection of an
appropriate forensic delay analysis method depends on several factors, including project complexity,
availability, and quality of documentation, and the
specific requirements of the dispute resolution
forum. Understanding the strengths and limitations
of TSWA and IAPA is therefore essential for
accurately analyzing delays and achieving fair and
defensible outcomes in data center construction
disputes.

Keywords: Construction, data center, delay analysis, impacted as-planned analysis (IAPA), time slice windows analysis (TSWA)
