      This Amendment No. 4 (the "Final Amendment") amends and supplements the

Industries, Inc., a Florida corporation ("Dycom"), and Troy Acquisition Corp., a
Delaware corporation and a wholly owned subsidiary of Dycom ("Purchaser"), on
January 23, 2002, as amended by Amendment No. 1 on February 5, 2002, Amendment
No. 2 on February 12, 2002 and Amendment No. 3 on February 12, 2002. This
Schedule TO relates to the offer by Dycom, through its wholly owned subsidiary,
Purchaser, to exchange for each outstanding share of common stock, par value
$.01 per share (together with the associated right to purchase preferred stock,
the "Shares"), of Arguss Communications, Inc., a Delaware corporation
("Arguss"), 0.3333 shares of Dycom Industries, Inc. common stock, par value
$0.33-1/3 per share (together with the associated right to purchase preferred
shares), upon the terms and subject to the conditions set forth in the
Prospectus dated January 23, 2002, as amended on February 5, 2002, February 11,
2002 and February 12, 2002 (the "Prospectus") and in the related Letter of
Transmittal which are Exhibits (a)(1) and (a)(2) to the Schedule TO.

      The information set forth in the Prospectus and the related Letter of
Transmittal is incorporated herein by reference in response to Items 2 - 11
of this Schedule TO.

     Pursuant to General Instruction H to Schedule TO, this Final Amendment
satisfies the reporting requirements of section 13(d) of the Securities Act of
1933, as amended, with respect to all Shares acquired by the Purchaser in the
offer. Capitalized terms used and not defined herein shall have the meaning
ascribed to such terms in the Prospectus or in the Schedule TO.

ITEM 11.     ADDITIONAL INFORMATION.

     Items 2 through 11 of this Schedule TO are hereby amended and supplemented
to include the following information:

      At 12:00 midnight, New York City time, on Wednesday, February 20, 2002,
the offer expired. Based on a preliminary count, approximately 13,722,092 Shares
were tendered pursuant to the offer (including shares guaranteed for delivery).
Such Shares constituted approximately 94.3% of the outstanding Shares. On
February 21, 2002, effective as of 9:00 a.m., New York City time, all Shares
validly tendered and not withdrawn prior to the expiration of the offer were
accepted for exchange.

     On February 21, 2002, pursuant to the merger agreement, Purchaser merged
with and into Arguss with Arguss surviving the merger as a wholly owned
subsidiary of Dycom. At the effective time of the merger, each Share owned by
Arguss, as treasury stock or owned by Purchaser, was canceled and retired, and
all other outstanding Shares were converted into the right to receive 0.3333
shares of common stock of Dycom (together with the associated right to purchase
preferred shares), the same consideration as in the offer.

      On February 21, 2002, Dycom issued the press releases filed as Exhibits
