Our Company, page 1

In response to the Staff’s comment, the Registrant has revised its disclosure on pages 2, 55 and 74.

The Registrant also believes that it has provided disclosure regarding the challenges it faces and the risks and limitations of its business under “Summary of Risk Factors” in the “Summary” section and the “Cautionary Statement Concerning Forward-Looking Statements” sections. Potential investors also have the benefit of the complete risk factors in the “Risk Factors” section that follows the Summary section. The Registrant has also provided disclosure related to its experiences with AECOM, as well as the services provided by the Registrant and ones on which the Registrant relies upon subcontractors and joint venture affiliates. The Registrant believes that it has adequately balanced this disclosure with market practice. Furthermore, while Morrison Knudsen is a legacy affiliate of the Registrant, references to Morrison Knudsen have been removed from the disclosure.

Our Market Opportunity, page 7

In response to the Staff’s comment, the Registrant has revised its disclosure on pages 7 and 82. The Registrant has also clarified that these statements refer to the serviceable obtainable market, that is, the market the Registrant believes it can address with its current capabilities.

In addition, we note that the circumstances for which the Registrant may need to make payments to AECOM are described in the Purchase Agreement entered into in connection with the AECOM Sale Transactions (the “Purchase Agreement”), which consist of (i) a retained claim reimbursement for a legacy project that has been completed and is the subject of an ongoing dispute (“Retained Claim Reimbursement A”), (ii) a potential retained claim reimbursement in an undetermined amount for a legacy project that has not yet been completed (“Retained Claim Reimbursement B”), (iii) a one-time cash payment in the event the Earnout Thresholds (as set forth in the Purchase Agreement) are achieved (the “Earnout”) and (iv) the payment of 50% of the amount of actual income tax benefits realized (i.e., in cash or through an actual reduction in liability for tax) as a result of AECOM’s election under Treasury Regulations Section 1.1502-36(d)(6) (the “Tax Benefits Obligations” and collectively with Retained Claim Reimbursement A, Retained Claim Reimbursement B and the Earnout, the “Contractual Obligations”).

With respect to Retained Claim Reimbursement A, which is the subject of an ongoing dispute, AECOM is seeking to recover $40 million. Thus the Registrant believes the maximum exposure relating to this claim is $40 million. The Registrant does not expect the case will be adjudicated until 2025.

With respect to Retained Claim Reimbursement B, while the legacy project has not yet been completed, and the total amount of the claim and the ultimate timing is uncertain, the Registrant does not expect it will be required to make any payments to AECOM.

With respect to the Earnout, the Registrant does not anticipate it will be obligated to make any payments to AECOM as it would need to achieve EBITDA (as defined in the Purchase Agreement) of approximately $268 million for the third quarter of 2023.

With respect to Tax Benefits Obligation, the ultimate amounts payable, if any, to AECOM will be based on the actual tax benefits realized by the Registrant. There is no guarantee that the Registrant will realize any such benefits.

In addition to the above, in connection with the settlement of a dispute regarding the amount of the closing net working capital adjustment under the Purchase Agreement (the “Net Working Capital Dispute”), the Registrant agreed to pay AECOM up to 10% of the amounts recoverable on account of a claim related a legacy project, up to maximum of $9.5 million. Accordingly, the Registrant maintains the full remaining amount of $9.1 million as a contingent liability as of June 30, 2023, as $0.4 million has been previously paid. However, the amount ultimately payable to AECOM will depend on the amount actually recovered by the Registrant on account of such claim, which may be less than the amount accrued as of June 30, 2023. There is no guarantee the Registrant will be successful in recovering any amounts under such claim, in which case no amounts would be payable to AECOM relating to this matter.

Based on the foregoing, the Registrant estimates that its obligations to AECOM as of June 30, 2023 were approximately $16.0 million, which have been recorded as contingent consideration as of June 30, 2023. However, there the ultimate amounts payable to AECOM may differ from such amounts based on final resolutions of the aforementioned claims and contractual provisions. Given that each of the Contractual Disputes (excluding AECOM’s dispute relating to Retained Claim Reimbursement A) and the Net Working Capital Dispute only require payments to AECOM based on amounts recovered by the Registrant (or via a reduction in tax liabilities), the proceeds from this offering would not be used to make these payments. And with respect to Retained Claim Reimbursement A, given that the Registrant does not currently owe any money to AECOM and the case is not expected to be adjudicated until 2025, none of the proceeds from the offering are expected to be used to make any such additional payments that may be determined to be owed to AECOM.

With respect to Item 404 of Regulation S-K, we respectfully inform the Staff that at no time during the Registrant’s 2021 fiscal year (January 2, 2021 – December 31, 2021) or 2022 fiscal year (January 1, 2022 – December 30, 2022) was AECOM a related person, as such term is defined in Instruction 1 to Item 404(a) of Regulation S-K.

As clarified in these revisions, we respectfully inform the Staff that “aggregates” refers to raw materials that are produced from natural sources and extracted from pits and quarries such as gravel, crushed stone and sand. “Aggregates” in this context does not refer and is not related to funds. To eliminate any ambiguities, references to “aggregate reserves” have been replaced in such instances with the term “aggregates.”

Financial Statements

Notes to the Consolidated Financial Statements

Note 1. Business, Basis of Presentation and Significant Accounting Policies, page F-7

In response to the Staff’s comment, we respectfully clarify for the Staff the timing of the sale of Shimmick to SCC Group. On January 2, 2021, SCC Group acquired 100% of SCCI National Holdings, Inc. stock and certain other assets and liabilities related to the SCCI National Holdings, Inc. business and subsidiaries from AECOM. Because SCC Group obtained control of the SCCI National Holdings, Inc. business, this transaction was accounted for as a business combination. SCC Group was created specifically for the purpose of acquiring SCCI National Holdings, Inc. from AECOM and, as a result of the business combination, SCCI National Holdings, Inc. become a wholly-owned subsidiary of SCC Group.

On the date that SCC Group acquired SCCI National Holdings, Inc., a subsequent merger of SCC Group and SCCI National Holdings, Inc. was not anticipated. The decision to merge the entities was made as a result of and in conjunction with SCCI National Holdings, Inc.’s IPO readiness process, which began later. Accordingly, on November 19, 2021, SCC Group was merged with SCCI National Holdings, Inc., with SCCI National Holdings, Inc. becoming the surviving entity. In the intervening period between January 2, 2021 and November 19, 2021, SCC Group’s assets and liabilities consisted of its investment in SCCI National Holdings, Inc., as well as rights to receive any net working capital settlement and any obligation to pay contingent consideration related to its January 2, 2021 acquisition of SCCI National Holdings, Inc.

September 14, 2023

Page Six

The November 19, 2021 merger of SCC Group with SCCI National Holdings, Inc. was accounted for as a combination of entities under common control. Accordingly, results of operations of the two entities have been combined from the point when they came under common control (i.e., when SCC Group acquired SCCI National Holdings, Inc. on January 2, 2021). The business combination is therefore reflected in the financial statements of the combined company for the year ended December 31, 2021.

SCC Group did not have substantive operations, assets or liabilities prior to the merger with SCCI National Holdings, Inc. except those pertaining to its acquisition of the SCCI National Holdings, Inc.

The Registrant notes that it will supplementally provide the Staff copies of any of the above-described written communications or research reports of which it becomes aware.
