As of 2026, AEC firms across the United States are working against one of the most important funding timelines in recent history. With key Infrastructure Investment and Jobs Act (IIJA) funding windows approaching their final obligation deadlines many tied to the September 30, 2026 federal fiscal year end documentation readiness has become just as critical as engineering design.
Many technically sound projects still face delays in funding approval. The reason is rarely a design failure. More often, it comes down to documentation gaps that trigger additional review cycles. Nearly 52%of construction rework in the U.S. stems from documentation errors, poor data, and miscommunication, leading to $31.3 billion in avoidable losses annually.
Below are some of the most common documentation mistakes that are delaying IIJA-funded projects, along with their impacts and practical ways to address them.
1. Submitting Drawing Sets That Are Not Fully Complete
Teams sometimes submit drawing packages that are close to completion, assuming small items can be resolved during review. Incomplete submissions are often returned without a detailed review. This resets approval timelines and increases the risk of missing funding deadlines tied to obligation schedules.
Solution
Implement a strict pre-submission checklist to confirm:
- All sheets are included
- Review comments are resolved
- General notes are finalized
- Coordination across disciplines is complete
Completeness at submission prevents avoidable delays.
2. Weak Version Control Across Teams
When multiple teams work simultaneously, outdated drawings can accidentally be included in final packages. Conflicting revisions or mismatched drawings create confusion during review. Resolving these issues takes time and often leads to resubmissions.
Solution
Establish a centralized document control system with:
- Shared document access
- Standard file naming
- Structured revision tracking
Strong version control reduces rework.
3. Delayed Right-of-Way Documentation
Right-of-way documentation is often completed late, even though it plays a major role in project approval. Incomplete ROW documentation can prevent agencies from finalizing agreements, delaying funding approvals even when design work is complete.
Solution
- Coordinate ROW tasks early and update documentation regularly throughout the project lifecycle.
- Early preparation avoids last-minute bottlenecks.
4. Missing Material Compliance Records
Federal infrastructure programs require clear documentation showing that materials meet domestic sourcing requirements. Incomplete compliance records may trigger additional verification or audits, delaying approvals and increasing administrative workload.
Solution
- Track material documentation from the project’s start and maintain organized records that are easy to review.
- Compliance should be managed continuously, not at the end.
5. Poor Coordination Between Disciplines
Projects involving civil, structural, and utility teams require consistent coordination to prevent conflicts. Unresolved conflicts between drawings often result in revision cycles that slow the approval process.
Solution
- Schedule regular coordination reviews and verify drawing alignment before submission.
- Early coordination saves time later.
6. Unclear Tracking of Design Changes
Frequent design updates are common in infrastructure projects, but incomplete documentation of changes can create confusion. Reviewers may need to reassess large portions of drawings when revisions are unclear, extending review timelines.
Solution
Maintain detailed revision logs that document:
- What changed
- When changes were made
- Why were updates required
Clear tracking supports faster reviews.
7. Overloading Engineers with Drafting Work
Under tight deadlines, engineers often take on drafting tasks to keep projects moving. This reduces the time available for quality reviews and increases the chance of errors, leading to more revision cycles.
Solution
- Separate design responsibilities from drafting tasks wherever possible. Assign routine production work to dedicated drafting resources.
- Balanced workflows improve both speed and quality.
8. Poor Financial Documentation and Cost Breakdown
Funding applications often fall short when financial documentation lacks clarity and structure. Missing detailed cost breakdowns, unclear separation of funding sources (such as federal versus local match), and the absence of inflation-adjusted projections make it difficult for reviewers to assess project feasibility.
- Incomplete or poorly structured financial information frequently leads to additional clarification requests and budget revisions. This extends review timelines and can delay grant agreements, even when the project itself is viable.
Cost escalation and unclear financial structuring have consistently been among the key challenges faced by IIJA awardees, highlighting the importance of strong financial documentation.
Solution
Maintain clear and structured financial documentation from the outset, ensuring:
- Detailed and itemized cost breakdowns
- Transparent identification of funding sources
- Inclusion of realistic, inflation-adjusted projections
Well-prepared financial documentation enables faster validation and smoother approvals.
9. Non-Compliance with Federal Requirements (BABA, NEPA, and Others)
Projects often face delays when federal compliance is either overlooked or poorly documented. Requirements such as Build America, Buy America (BABA), NEPA environmental reviews, and labor and procurement standards demand clear, complete, and well-structured documentation.
- Gaps or inconsistencies in these areas frequently lead to applications being flagged for non-compliance, triggering additional documentation requests, waivers, and extended review timelines.
For instance, BABA requires detailed documentation of material origin and manufacturing processes, yet this is often incomplete or not presented in a review-friendly format, creating avoidable bottlenecks during evaluation.
Solution
Manage compliance documentation proactively throughout the project lifecycle, ensuring:
- Clear documentation of BABA requirements, including material sourcing and manufacturing details
- Complete and up-to-date environmental review records (NEPA)
- Proper documentation of labor and procurement standards
Consistent, well-structured compliance documentation reduces review friction and enables faster approvals.
10. Weak Subrecipient & Contractor Documentation
IIJA-funded projects often involve multiple stakeholders, including subconsultants, contractors, and subrecipients. However, documentation across these entities is frequently incomplete or inconsistent, including:
- Missing compliance records
- Lack of certified payroll documentation
- Poor subcontractor monitoring
These gaps increase audit risk and can delay fund disbursement, even when primary project documentation is in place. Monitoring subcontractor compliance and maintaining accurate, up-to-date records remain common challenges in federally funded projects.
Solution
Establish structured oversight processes to ensure:
- Complete and verified compliance documentation across all stakeholders
- Proper maintenance of certified payroll records
- Ongoing monitoring and documentation of subcontractor performance
Strong documentation across all project participants reduces risk and supports smoother fund release.
Why Documentation Matters More Under IIJA Timelines
Under traditional project schedules, documentation issues cause delays. Under IIJA timelines, they can affect funding eligibility. With major obligation deadlines approaching in 2026, agencies must finalize project agreements within strict timeframes. That means incomplete documentation can directly impact funding outcomes. Strong documentation practices are now essential to protecting project timelines.
- Most approval delays are not caused by major technical issues. They result from small documentation gaps that accumulate over time.
- Firms that prioritize documentation readiness early are better positioned to meet deadlines, reduce revisions, and maintain project momentum.
In the current funding environment, documentation discipline is a practical advantage.
When Additional Support Becomes Valuable
As funding deadlines approach, production workloads increase quickly. Many mid-sized firms find their teams capable but stretched thin by documentation demands. Additional drafting and modeling support can help manage this surge without disrupting ongoing projects. This allows engineering teams to stay focused on decision-making while documentation continues to move forward.
If your documentation backlog is growing as key IIJA deadlines approach, reviewing your current capacity now can help prevent delays later. At Intrivis, we can support you with your needs. Let’s get going today!
