Accounting Policies [Abstract]
Basis of Presentation	Dycom Industries, Inc. (“Dycom”, the “Company”, “we”, “our”, or “us”) is a leading provider of specialty contracting services throughout the United States. These services include program management; planning; engineering and design; aerial, underground, and wireless construction; maintenance; and fulfillment services for telecommunications providers. Additionally, Dycom provides underground facility locating services for various utilities, including telecommunications providers, and other construction and maintenance services for electric and gas utilities. Dycom supplies the labor, tools, and equipment necessary to provide these services to its customers.
Accounting Period	Our fiscal year ends on the last Saturday in January. As a result, each fiscal year consists of either 52 weeks or 53 weeks of operations (with the additional week of operations occurring in the fourth quarter). Fiscal 2023 and fiscal 2024 each consist of 52 weeks of operations. The next 53 week fiscal period will occur in the fiscal year ending January 31, 2026.
Segment Information	Segment Information. The Company operates in one reportable segment. Its services are provided by its operating segments on a decentralized basis. Each operating segment consists of a subsidiary (or in certain instances, the combination of two or more subsidiaries), whose results are regularly reviewed by the Company’s Chief Executive Officer, the chief operating decision maker. All of the Company’s operating segments have been aggregated into one reportable segment based on their similar economic characteristics, nature of services and production processes, type of customers, and service distribution methods.
Use of Estimates	Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the amounts reported in these condensed consolidated financial statements and accompanying notes. These estimates are based on our historical experience and management’s understanding of current facts and circumstances. At the time they are made, we believe that such estimates are fair when considered in conjunction with the Company’s consolidated financial position and results of operations taken as a whole. However, actual results could differ materially from those estimates.
Recently Issued Accounting Pronouncements	Recently Adopted Accounting Standards Business Combinations. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The amendments in ASU 2021-08 require acquiring entities to apply ASU 2014-09, Revenue from Contracts with Customers (Topic 606) to recognize and measure contract assets and liabilities in a business combination. This update is intended to improve comparability after the business combination by providing consistent recognition and measurement of acquired revenue contracts and revenue contracts with customers not acquired in a business combination. ASU 2021-08 is effective for annual periods beginning after December 15, 2022 and interim periods within those annual periods, with early adoption permitted. The amendments in ASU 2021-08 should be applied prospectively. We adopted the provisions of ASU 2021-08 in the first quarter of fiscal 2024 and there was no material effect on our consolidated financial statements. Accounting Standards Not Yet Adopted Reference Rate Reform. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ASU 2020-04 provides temporary optional expedients and exceptions to the guidance in U.S. GAAP on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from LIBOR and other interbank offered rates to alternative reference rates. ASU 2020-04 was effective for adoption at any time between March 12, 2020 and December 31, 2022. In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848. ASU 2022-06 defers the sunset date included within Topic 848 from December 31, 2022 to December 31, 2024. We will adopt the provisions of ASU 2020-04 in the second quarter of fiscal 2024 and do not expect the adoption to have a material effect on our consolidated financial statements. Leases. In March 2023, the FASB issued ASU 2023-01, Leases (Topic 842): Common Control Arrangements. The amendments require all entities including public companies to amortize leasehold improvements associated with common control leases over the useful life to the common control group. ASU 2023-01 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted for both interim and annual financial statements that have not yet been made available for issuance. If an entity adopts the amendments in an interim period, it must adopt them as of the beginning of the fiscal year that includes that interim period. Transition can be done either retrospectively or prospectively. We will adopt the provisions of ASU 2023-01 in the first quarter of fiscal 2025 and do not expect the adoption to have a material effect on our consolidated financial statements. All other new accounting pronouncements that have been issued but not yet effective are currently being evaluated and at this time are not expected to have a material impact on our financial position or results of operations.
