Protest 014: NB405 Bridge 405/103E Widening — ATC-1 Interpretation

Date: 2026-03-12
Prepared by: WSDOT Claims Analysis
Subject: Protest 014 — NB405 Bridge 405/103E Widening / ATC-1 Interpretation — Internal Analysis and DRB Preparation
Responding to: Skanska LTR 356 (Feb 20, 2026) — Notice of Protest 014; Skanska LTR 370 (Mar 6, 2026) — GP 1-04.5(2) Supplemental
Determination deadline: ~March 27, 2026 (21 calendar days after supplemental receipt per GP 1-04.5)

Evaluation Framework

  1. Does ATC-1 require structural continuity between the widening and the existing structure? YES.
  2. Does WSDOT’s correction of “Forward Compatibility” terminology withdraw the ATC-1 requirement? NO.
  3. Is the Design-Builder entitled to cost or time adjustments? NO.
Finding Summary: The protest is without merit. ATC-1 was approved unconditionally and is incorporated into the contract through the DB’s Proposal. ATC-1 text (Items 3, 4, 6) and Figure 2 establish structural continuity. The DB is not entitled to adjustments.

ATC-1 Incorporation

ATC-1 was approved unconditionally during the procurement phase and is incorporated into the contract through the DB’s Proposal. Per GP 1-03.2, the DB’s Proposal (including all approved ATCs) forms part of the contract documents. ATC-1’s text and figures are binding contract requirements, not merely suggestions or design guidance.

Read-Together Analysis

When ATC-1 Items 3, 4, and 6 are read together with Figure 2 and the unmodified RFP 2.13.4.1.2 continuity requirement, a single coherent picture emerges: the widening must be structurally continuous with the existing bridge. The DB’s attempt to parse individual items in isolation ignores the contract’s integrated structure. Figure 2 (C-227) depicts a COMBINED SPREAD FOOTING with continuous widening — this is the graphic expression of the textual requirements.

Pillar 1 — Forward Compatibility Correction Does Not Withdraw ATC-1 Requirement

WSDOT corrected the “Forward Compatibility” terminology in SL 9727-237 but expressly reaffirmed the underlying structural continuity requirement. The label was imprecise; the requirement (Items 3, 4, 6) stands independently of whatever terminology is used to describe it.

Correspondence Sequence:

The correction of a label does not withdraw the substance. Items 3, 4, 6, and Figure 2 exist independently of whatever name WSDOT or Skanska attach to the concept. Skanska’s argument conflates terminology correction with substantive withdrawal.

Pillar 2 — ATC-1 Text Establishes Structural Continuity

This is the core of the dispute. Each ATC-1 element independently supports structural continuity:

ATC-8 Consistency Rebuttal: The DB may argue that ATC-8 demonstrates a different approach. ATC-8 addresses a different bridge with different conditions and different contract provisions. Different bridges have different contracts — this comparison is irrelevant.

Pillar 3 — GP 1-03.2 Clause 3 Binds DB to ATC Commitments

GP 1-03.2 Clause 3 establishes that where the DB’s Proposal offers higher quality, additional services, or terms more advantageous to WSDOT, those commitments are binding. The clause operates in one direction only — it elevates the DB’s commitments but never reduces contract requirements.

Continuous widening per ATC-1 qualifies under all three categories:

  1. Higher quality: Structural continuity provides superior seismic and load-transfer performance.
  2. Additional services: ATC-1 commits the DB to a specific design approach beyond the base RFP requirements.
  3. Terms more advantageous to WSDOT: A continuous structure serves WSDOT’s long-term asset management interests.

Pillar 4 — GP 1-04.4(5)(n) Risk Allocation Is Absolute

GP 1-04.4(5)(n) states that ATC implementation costs are the DB’s exclusive responsibility. This provision is absolute — it does not contain exceptions for cost increases, unforeseen difficulties, or changed interpretations. Regardless of the outcome of the structural continuity question, the DB bears the cost of implementing ATC-1 as written.

Pillar 5 — Comment #9 Closure Does Not Constitute Acceptance

HIGHEST PRIORITY — New argument requiring detailed rebuttal.

Terry Bondy (sheet BF06) asked why the closure pour was NOT shown — a comment that questions an omission. AECOM mischaracterizes this as a neutral inquiry. Eight-point rebuttal:

  1. The comment questions an omission. Bondy asked why the closure pour was not shown. The question itself presupposes that it should have been shown. This is a flag, not an endorsement.
  2. GP 1-03.7 defines “approved.” Per GP 1-03.7, “approved” means conformance to contract. Approval of a submittal does not waive contract requirements that the submittal failed to address.
  3. Pang did not close it. The reviewer who raised the comment is not the same as the individual who resolved it. Comment tracking records must be examined for who actually marked closure.
  4. Design review is iterative. Comments at the preliminary stage do not constitute final acceptance. The design review process contemplates multiple rounds of refinement.
  5. DBIC was the proper vehicle. If the DB intended to deviate from ATC-1 requirements, the contractually proper path was a Design-Builder Initiated Change (DBIC), not silent omission from a submittal.
  6. Contract text was available throughout. ATC-1 text and Figure 2 were available to all parties at every stage. Comment closure does not override written contract provisions.
  7. “Reversal” is a mischaracterization. WSDOT did not reverse its position. WSDOT identified a nonconformance and directed compliance. That is standard contract administration.
  8. AECOM’s language escalates within a single document. AECOM’s characterization of the comment history grows more aggressive within its own submission, revealing advocacy rather than factual recitation.

Pillar 6 — Reliance/Estoppel Fails

The reliance/estoppel argument fails on multiple grounds:

Pillar 7 — Changed Geotechnical Conditions Don’t Change Contract Text

The DB argues that changed geotechnical conditions justify deviating from ATC-1’s structural continuity requirement. This argument fails because:

Pillar 8 — BDM and Industry Practice Don’t Override Contract

Pillar 9 — Sonia Berriz Statement Does Not Undermine WSDOT

The DB cites a Sonia Berriz statement to suggest internal WSDOT disagreement. This argument actually supports WSDOT:

II. Rebuttal of LTR 356 Assertions

DB Assertion (LTR 356)WSDOT Rebuttal
ATC-1 does not require structural continuity between widening and existing structure.Items 3, 4, 6, and Figure 2 independently and collectively establish structural continuity. See Pillar 2.
WSDOT withdrew the “Forward Compatibility” requirement in SL 237.SL 237 corrected terminology but expressly reaffirmed the substantive requirement. See Pillar 1.
Comment #9 closure constitutes acceptance of the DB’s design approach.Comment closure does not override contract provisions. GP 1-03.7 defines “approved.” See Pillar 5.
The DB reasonably relied on WSDOT’s apparent acceptance.Reliance fails. Contract text was available throughout. RFI 461 undermines reliance. See Pillar 6.
Changed geotechnical conditions justify deviation from ATC-1.ATC-1 obligation is unconditional. Proper path is DBIC. See Pillar 7.
BDM and industry practice support the DB’s approach.External standards do not override specific contract text. See Pillar 8.

Rebuttal of LTR 370 Supplemental Assertions

DB Assertion (LTR 370)WSDOT Rebuttal
AECOM analysis of comment #9 history shows WSDOT accepted non-continuous design.Comment questions an omission, not endorses it. AECOM’s language escalates within its own document. See Pillar 5.
Sonia Berriz statement shows internal WSDOT disagreement.Berriz statement actually supports WSDOT (“do not believe design meets contract requirements”). See Pillar 9.
ATC-8 demonstrates WSDOT accepts non-continuous approach for other bridges.Different bridges have different contracts. ATC-8 addresses a different structure with different provisions.
Pat’s admission supports design flexibility.Pat’s statement (“thought they would be ok”) is an informal comment that does not override written contract provisions or GP 1-03.7.

Pre-Empted Counter-Arguments

IDAnticipated ArgumentPre-Emption
CA-1WSDOT is changing its position after years of apparent acceptance.WSDOT identified a nonconformance and directed compliance. Standard contract administration. Consistent direction since March 2025.
CA-2The cost of structural continuity exceeds the DB’s bid assumptions.GP 1-04.4(5)(n): ATC implementation costs are DB’s exclusive responsibility regardless of magnitude.
CA-3Structural continuity is not feasible given site conditions.WSDOT offered DBIC path for infill shear walls. Feasibility challenges require DBIC, not unilateral deviation.
CA-4The contract is ambiguous regarding continuity.Items 3, 4, 6, Figure 2, and RFP 2.13.4.1.2 are unambiguous. Read-together analysis yields a single coherent interpretation.

III. Gaps in Their Submittal

IV. Direction Already Provided

Rebuts any claim that WSDOT has not provided sufficient direction.

DateDocumentDirection Given
2025-08-19WSDOT SL 9727-201Initial direction identifying ATC-1 structural continuity requirement for 405/103E widening. Established WSDOT’s position that the DB’s design must conform to ATC-1 commitments.
2025-11-18WSDOT SL 9727-237Corrected “Forward Compatibility” terminology. Expressly reaffirmed the structural continuity requirement based on ATC-1 Items 3, 4, 6, and Figure 2.
2026-02-10WSDOT SL 9727-262Responded to LTR 333. Reaffirmed WSDOT’s position. Reiterated that ATC-1 requires structural continuity and that DBIC is the proper vehicle for any proposed deviation.

WSDOT has provided three written communications over six months, maintained a consistent position throughout, and offered to support a DBIC for alternative approaches to meeting the structural continuity requirement.

V. Entitlement Analysis

VI. Disposition of Relief Requested

RequestDispositionRationale
Recognition that ATC-1 does not require structural continuityDENIEDATC-1 Items 3, 4, 6, Figure 2, and RFP 2.13.4.1.2 establish structural continuity. Read-together analysis is unambiguous.
Additional compensation for structural continuity implementationDENIEDGP 1-04.4(5)(n): ATC implementation costs are DB’s exclusive responsibility.
Contract Time adjustmentDENIEDGP 1-04.4(5)(m) and (n): ATC-related schedule impacts within DB risk allocation.
Withdrawal of WSDOT direction requiring continuityDENIEDWSDOT direction is consistent with contract requirements. No basis for withdrawal.

VII. Path Forward

Option A — Deny after supplemental review. Issue determination denying Protest 014 on all grounds. Reaffirm SL 9727-262 and the structural continuity requirement. Cite dispute procedures per GP 1-04.5(1). The determination must address each pillar concisely, with emphasis on Pillar 5 (Comment #9) as the DB’s strongest new argument.

Option B — Proactive DRB preparation. Begin assembling the DRB position paper now. Structure around the nine pillars. Prepare witness outlines for Berriz, Sizivu, Bondy, and Pang. Compile the full comment #9 history with original records (not AECOM’s characterization). Prepare a read-together exhibit showing ATC-1 Items 3, 4, 6, and Figure 2 side by side.

Recommendation: Pursue both concurrently. The determination deadline (~March 27, 2026) requires prompt action on Option A, while DRB preparation should proceed in parallel given the near-certainty that the DB will escalate to dispute.
