Introduction to Delays

Delayed completion is an unfortunate reality on many construction projects. Despite the best-laid plans, unforeseen events can impede progress and push the project finish date out further into the future. These delays add costs, complicate logistics, strain relationships, and prevent the asset from starting revenue generation as planned.

When delays occur, the completion date written into the original contract is no longer feasible. The schedule must undergo analysis and negotiation to set a new, attainable project end date. This is a complex process with major commercial implications for all parties involved.

This article will examine the ins and outs of delays and completion date adjustments for construction projects. We will look at common causes of delays, their consequences, methods for evaluating delay claims, and best practices for mitigating schedule slips proactively. Approaches for forensic schedule analysis and advanced simulation will also be discussed.

By understanding the dynamics of delays and schedule recovery, project teams can minimize disruption when the inevitable hiccups occur. With rigorous upfront planning, active monitoring, and prompt response, completion deadlines can stay on track more often, leading to successful projects without the friction of delay claims.

Causes of Delays

Many factors can derail construction schedules, including:

Design changes or deficiencies – Additional scope, incomplete designs, or errors requiring rework negatively impact the schedule.

Permitting issues – Failure to secure permits on time delays eligible work. Permit denials or conditions require redesign.

Adverse weather – Unusually severe or frequent storms lead to lost work days and disruption.

Late delivery of materials – Delays in material shipments pushes out dependent work activities.

Subcontractor deficiencies – Subpar subcontractor performance slows progress. Financial issues can stop work entirely.

Scope changes – Added or changed scope affects activity logic and durations.

Unforeseen conditions – Undisclosed site conditions require changes to previously planned work.

Owner interference – Slow owner approvals, access limitations, or work stoppage orders delay contractors.

Deficient coordination – Poor coordination between parties working in same area reduces productivity.

Rework – Defects or failure to meet specifications requiring correction put activities on hold.

Inadequate project management and oversight – Lack of active schedule tracking and recovery efforts allows delays to accumulate.

Inaccurate scheduling – Original schedule durations were too aggressive given true production rates.

Inappropriate sequencing – Work sequences did not optimize workflow and lead to inefficiencies.

Resource issues – Insufficient or underperforming workers, equipment failure, and constraint trade skill availability constrain the schedule.

Funding issues – Lack of payments affects contractor cash flow, slowing procurement and execution.

Regulatory factors – Requirements like environmental restrictions or safety shutdowns lead to delays.

Consequences of Delays

The impacts of delayed project completion manifest in different ways for various stakeholders:

For Owners

For Contractors

  • Acceleration costs to regain schedule – Overtime, additional shifts, and other crash efforts add expense.
  • Reduced labor productivity – Out-of-sequence work, overcrowding, and rework hamper productivity.
  • Breach of contract claims – Failure to finish on time constitutes default, although excusable delays may relieve this.
  • Reassignment of resources – Crews get pulled off schedule to work on other jobs.

For Subcontractors

  • Disruption of trade sequencing – Out-of-order work flow hampers specialty crews. Makes optimized staffing difficult.
  • Compression of schedules – Stacked trades working simultaneously in space intended for linear sequence.
  • Lower morale and fatigue – Extended durations and acceleration take a toll on workforce. Increased safety risks.
  • Additional equipment/staffing costs – Extra resources may be needed for compression.

Evaluating Delay Claims

When delays occur, a rigorous process is required to evaluate claims and determine schedule adjustments:

  • Document causes and impacts – Compile evidence like daily reports, correspondence, and meeting minutes to prove root cause.
  • Categorize excusable vs. inexcusable delays – Excusable delays arising from unforeseeable events justify time extension. Inexcusable delays caused by a party’s actions do not warrant extension.
  • Calculate effects on critical path – Delay must affect an activity on the critical path to push out project completion date. Non-critical delays may not lead to time impacts.
  • Determine accountable parties – Identify which party is responsible for each delay event based on contractual liability and factual documentation.
  • Quantify costs – Calculate the direct costs attributable to each delay for monetary damages. Factor in productivity loss, acceleration, overhead overruns, etc.
  • Assess concurrency – Analyze situations where multiple delay events overlap at different times. Apportion delay and costs to responsible parties.
  • Negotiate schedule recovery – Discuss with owner potential ways to optimize the remainder of the schedule and recover lost time through greater work force, longer hours, acceleration, etc.

Adjusting the Completion Date

Once delay claims are validated, a new project completion date must be set. This involves:

  • Change order process – Formal contract change order executed to push out original completion date.
  • Negotiating schedule recovery – Agree on mitigation strategies like acceleration and added shifts where feasible to minimize extension needed.
  • Accelerating work – Crash the schedule duration for certain activities through overtime, extra crews, and other techniques.
  • Managing ripple effects – Re-sequence affected activities and modify logic ties to accommodate revised work flow under new completion deadline.
  • Reset baseline schedule – Update the project baseline schedule to accurately reflect the new targeted completion date and critical path.
  • Confirm adequate liquidated damages – Ensure the specified late completion penalties provide adequate owner protection under the revised schedule.
  • Secure surety consent – Obtain the surety’s consent to the change order if required by bond terms.

Address lending terms – Renegotiate loan terms if completion delay affects any financing conditions or defaults.

Mitigating Future Delays

Looking beyond a specific delay event, project teams should implement broader protocols to avoid delays proactively:

In Contracting

  • Clear schedule requirements and review stages – Specify schedule submittal requirements, update frequency, and owner review process.
  • Change order process for addressing delays – Outline formal process to resolve delays and adjust schedule via change orders.
  • Liquidated damages for late completion – Set reasonable late completion penalties to protect owner interests in event of contractor delays.

In Planning

  • Detailed scheduling with float and contingencies – Build a comprehensive critical path schedule with buffered task durations and contingencies.
  • Logical sequencing of interdependent activities – Sequence activities to optimize workflow and resource movement among tasks and areas.
  • Realistic activity durations – Allow realistic timeframes based on historical production rates and resource constraints. Avoid overly aggressive durations.

During Project

  • Close schedule monitoring – Track progress closely versus baseline. Require timely task updates. Flag slippage early.
  • Early identification of slipping activities – Don’t allow delays on non-critical paths to become critical. Act before cascade effects occur.
  • Proactive changes to regain critical path – Implement schedule recovery efforts like logic changes, resource reallocation, or re-sequencing to maintain critical path integrity.

Advanced Schedule Analysis

Sophisticated techniques help analyze delay causes and impacts:

  • Forensic schedule analysis – Uses detailed historical records to piece together delay events on a timeline to correlate to impacts. Aids in disputes.
  • Time impact analysis – Studies isolated effects of specific delays to quantify true impact versus excusable concurrent delays. Models “what if” scenarios.
  • Schedule simulation and modeling – Iteratively models the schedule and risks to forecast outcomes under various delay scenarios and mitigating actions.
  • CPM scheduling software – Specialized programs perform delay analysis functions and generate reports to support delay claims.

The Future of Project Delay Management

Advancing technology will transform delay management:

  • Predictive analytics to identify risks – Artificial intelligence scans historical, real-time, and forecast data to highlight developing problems early.
  • Real-time schedule tracking – Wearables, mobile devices, sensors, and drones provide constant field progress monitoring to update schedules dynamically.
  • Automated notifications and status updates – Alert project team in real-time to slipping activities before small issues snowball.
  • Automated scheduling functions – Machine learning optimizes schedules, sequences, resource allocation, and simulates outcomes to minimize delays proactively.

Conclusion

Delays remain an ever-present obstacle in construction, arising from countless events that impede progress. While some delays are unavoidable, a proactive approach focused on advanced planning, vigilant oversight, early action, and prompt dispute resolution can greatly reduce late completion and associated costs.

New technologies will amplify project teams’ ability to foresee risks, track real-time progress, simulate alternatives, and make data-driven decisions to drive on-time delivery. However, fundamental principles like understanding activity logic, managing resources judiciously, and acting quickly when delays occur will not change. Adaptable project managers who deploy the right blend of these strategies will be well-equipped to tackle the inevitability of schedule delays.
