Case Study: Time Slice Windows Analysis

Case Study: Time Slice Windows Analysis Time Slice Windows Analysis divides the project into time periods and analyses each period using the programme update available at the begin

Delay analysis

Time Slice Windows Analysis

This is another method that uses project segmentation by windows, but unlike APABW it depends on contemporaneous schedules issued by the contractor.

Planning

Contracts and planning

The contract is the main tool available to all parties involved to ensure proper scope management.

Project planning

Lookahead Schedule

In many projects it is not practical to use the master schedule, with hundreds or thousands of activities, to define and show the next tasks to be performed.

Planning

Schedule levels

There are 5 levels of detail for a schedule, each with a different objective, from contractual milestones to maximum activity detail.

Project planning

Project Progress with Primavera P6

One of a planner's functions is to update project progress. Depending on the project phase and type, progress must be updated in different ways.

Data and automation

Automating reporting and centralising data

Problem: data is scattered and the report is rebuilt manually every week. Solution: centralise everything on a single source of truth and automate reporting.

Project management

Project planning: when to subcontract it, when to internalise it and when it is not needed

Not every project needs a professional planner, and not every company should subcontract planning. An honest analysis of the three options.

Planning

PlanBuilt methodology

Most delays do not start with a bad schedule, but with the gap between what is planned in the office and what happens on site.

Project planning

From Paper Schedules to AI

In 30 years the sector has moved from paper schedules to real-time updates and AI. But there is a trap: many companies changed the tool without changing the method.

Project management

How much does a planner really cost? Spain 2026

A planner's salary is only the tip of the iceberg: social security contributions, software and overhead must also be added.

Delay analysis

Measured mile analysis

The most common method for resolving a disruption claim is measured mile analysis. This methodology compares actual productivity with affected productivity.

Delay analysis

Delay Analysis for Expert Reports

There are several delay analysis techniques for expert reports. The SCL recognises 6 techniques while the AACE recognises 8, although many have elements in common.

Delay analysis

As-Planned vs As-Built Windows Analysis

The As-Planned vs As-Built Windows Analysis method applies windows analysis by comparing executed dates with planned dates.

Planning

CPM and Last Planner System

CPM and LPS operate at different planning levels: time-contractual model versus production control and site coordination.

Delay analysis

Disruption analysis

The disruption suffered by the contractor must be demonstrated through analytical methods and techniques that allow the loss of productivity to be evaluated and quantified.

Project planning

Planning Best Practices

It is important to use best practices that improve the quality of the schedule and the planning process, and make it easier to detect errors and problems.

Project management

Types of construction contracts: a simple guide to understand and consult them

Construction contract types require distinguishing how the project is paid, how it is organised and who assumes the risk.

Delay analysis

Extension of Time EOT claim

Delays are almost inevitable. An EOT claim is the mechanism through which a contractor requests more time and avoids delay penalties.

Delay analysis

Types of Claims in Construction

Given the complexity of many construction projects today, delays to the completion date are common, and therefore so are claims.

Delay analysis

As-Planned vs As-Built

The As-Planned vs As-Built method is an observational technique that compares what should have happened with what actually happened.

Planning

The role of the planner

The planner occupies a unique position because every function needs a time dimension.

Project management

Project Controls Team

Planner, Quantity Surveyor and Cost Controller: how to integrate time, quantities, cost, contracts and execution in construction projects.

Project management

What a planning department really does

The department builds the time model, measures progress, anticipates deviations, assesses the impact of changes and supports the contractual position.

Delay analysis

Impacted as Planned

IaP is a modelled technique based on creating a simulation by inserting activities into the baseline programme with all activities linked.

Project planning

Steps to Create a Good Schedule

A good schedule should be structured in a way that is easy to understand while still providing enough detail to add value to the team.

Data and automation

Primavera P6 database

In Primavera P6, project information is stored in a relational database instead of independent files as in MS Project.

Planning

Constraints

Constraints are used to artificially modify or restrict the dates of a milestone or activity. The recommendation is that a well-built schedule should not contain any constraints.

Project planning

Critical Path in Primavera P6 and MS Project

The critical path of a project is the sequence of activities with zero float. It is the longest continuous sequence of activities in the schedule.

Delay analysis

Delay analysis methods

Given the complexity of many modern construction projects, delays to the completion date are common because permits, labour, materials and interfaces must be coordinated.

Delay analysis

Time Impact Analysis

TIA is a modelled technique based on simulating delays in a schedule updated to a date before the delay event and recalculating the impact.

Delay analysis

Collapsed as Built

This is a modelled technique based on scenario simulation. The simulation is carried out in Primavera or Project. It is not a recommended method for arbitration.

Delay analysis

Impacted as Planned Case Study

Impacted as Planned is a modelled technique based on creating a simulation by inserting activities into the baseline programme with all activities linked.

Planning

Converting from Primavera P6 to MS Project

Sometimes it may be necessary to convert a schedule created in Primavera P6 to MS Project because of specific project requirements.

Delay analysis

Classification of delay analysis methods (AACE/SCL)

To facilitate classification, the AACE taxonomy has been combined with the six main SCL methods.

Delay analysis

Collapsed as Built Case Study

The Collapsed as Built technique requires modelling the as-built programme. In this example, a wind farm with three main stakeholders will be analysed.

Project planning

Costs and Earned Value in Primavera P6

In a construction project there are different types of costs, depending on the scope, type and scale of the project.

Project planning

Assessing Schedule Quality

Planning quality can be analysed from a qualitative and quantitative perspective. The qualitative view is based on judgement, while the quantitative view uses measurable criteria.

Delay analysis

Relevant factors in choosing the analysis method

The choice of analysis method can be the key difference between winning or losing an arbitration and can also produce different results.

Planning

Duration type in Primavera P6

In Primavera P6, Duration Type is a setting that specifies how the software should calculate the duration of an activity.

Delay analysis

Causes of delay

Complex projects can suffer delays for many reasons, but some delay causes are common across most construction projects.

Project management

Site Sayings and Excuses: What the Workface Knows About Planning

On any construction site, before P6 there is oral tradition. Some sayings encode real planning discipline; others are excuses that sabotage it.

Delay analysis

Pacing and disruption

Pacing occurs when the completion of an activity is consciously and voluntarily delayed.

Delay analysis

Delays in construction projects

A delay is any event that prevents agreed dates from being maintained. In complex works they are very common, and the associated extra costs must be borne by one of the parties.

Data and automation

Power BI and Primavera P6

Primavera is the scheduling engine; Power BI is the analysis and visualisation layer it lacks. Reporting automation is the real objective.

Delay analysis

Participants in a construction project

Construction projects involve several parties whose roles and obligations affect progress, responsibility and delay analysis.
