UNITED STATES DISTRICT COURT NORTHERN DISTRICT OF ALABAMA NORTHEASTERN DIVISION

ZP 360 HUNTSVILLE MOUNTAIN, LLC, et al., Plaintiffs,

v. Case No. 5:23-cv-1178-CLM

AEC SITE SOLUTIONS, LLC, Defendant.

MEMORANDUM OPINION In early 2022, ZP 360 Huntsville Mountain, LLC (“ZP 360”) and ZP 361 Huntsville Research Park QOZB, LLC (“ZP 361”) (collectively, “Zimmer”) set out to build two multi-family housing developments in Huntsville. Zimmer hired a general contractor. The general contractor then hired a subcontractor, AEC Site Solutions, LLC (“AEC”), and work began. But within just a few months, things started to go wrong. The general contractor failed to meet expectations, so Zimmer terminated its contracts. And less than a year later, after Zimmer filled the general contractor’s shoes, Zimmer also terminated AEC’s subcontracts. Zimmer eventually managed to complete the projects. Still, the damage was done. Constant delays and reworks cost Zimmer time and money. So Zimmer sued AEC to recoup losses that, it says, are attributable to AEC and its deficient performance. Zimmer brings two claims for negligence and two for breach of contract. The parties now move for summary judgment. AEC asks for summary judgment on each of Zimmer’s claims. (Docs. 78, 79). Zimmer asks for partial summary judgment on its breach of contract claims. (Doc. 88). And Zimmer also seeks to strike AEC’s amended answer and affirmative defenses that it filed after discovery ended. (Doc. 75). For the reasons stated below, the court (1) GRANTS IN PART and DENIES IN PART AEC’s motions for summary judgment, (2) DENIES Zimmer’s partial motion for summary judgment, and (3) DENIES Zimmer’s motion to strike AS MOOT. BACKGROUND This case stems from AEC’s work as a subcontractor for two housing development projects owned by Zimmer entities. ZP 360 is the owner and developer of one of those projects, the Terraces at High Mountain (the “Terraces”). ZP 361 is the owner and developer of the other project, the Boardwalk at Research Park (the “Boardwalk”). The key facts for the two projects, and Zimmer’s claims, largely overlap. A. The Parties and Projects On February 28, 2022, ZP 360 hired Huffman Contractors (“Huffman”) to serve as general contractor on its Terraces project.1 (See doc. 86-4). A little over a week later, on March 8, ZP 361 hired Huffman to serve as general contractor on its Boardwalk project. (See doc. 80-2). Huffman then signed subcontracts with AEC for both projects. (See docs. 84-3; 88-9). 1. The Terraces The Terraces project called for the construction of six apartment buildings and a clubhouse. Each building was assigned an identification number, with A1-A6 denoting the apartment buildings and A7 the clubhouse. Because the Terraces site is located on hillside terrain, the buildings had to include a “lower-level pad” and an “upper-level pad.”2 (See doc. 85-2, p. 6). After the lower-level pads were completed, “stem walls or retaining walls were required to be constructed” before the upper- level pads could be built. (Docs. 81-1, p. 12; 84-2, p. 14). AEC’s job was to perform site work, “including but not limited to, demolition, erosion control, grading, paving, utilities and other related services.” (Doc. 6, pp. 4-5). Some of AEC’s tasks under these categories included: preparing the

1 Different Huffman entities served as the general contractors on the projects, but AEC’s corporate representative confirmed during his deposition that AEC “just knew” them both as “Huffman.” (See doc. 88-1, p. 46-47). So this opinion treats Huffman as one entity. 2 “Pads” are cleared and leveled areas of land that “allow for follow-on construction of each pad’s underslab utilities.” (See doc. 85-2, p. 8). Once the underslab utilities are constructed, a concrete slab goes on top so “vertical construction” can start. (See id.). building pads, installing sanitary and storm sewers, and completing an on-site water tie-in. A general layout of the Terraces site is shown below:

(Doc. 85-2, p. 7). 2. The Boardwalk The Boardwalk project was divided into two phases. Phase 1 called for the construction of four multi-story apartment buildings, Al-A4, and Phase 2 called for the construction of two additional buildings, A5-A6. Unlike the Terraces, the Boardwalk site was flat. But AEC’s scope of work for the Boardwalk was largely the same as its scope of work for the Terraces. So AEC was again tasked with, among other things: preparing the building pads, installing sanitary and storm sewers, and completing an on-site water tie-in. A general layout of the Boardwalk site is shown below:

(Id., p. 8). 3. Project Schedules As general contractor, Huffman developed schedules for both projects. These schedules purportedly included deadlines for AEC to complete certain tasks within its scope of work. The parties dispute whether AEC received some of these schedules or agreed to be bound by them. But the record evidence shows that, at the very least, AEC received a milestone chart for the Terraces project on July 20, 2022. The relevant portion of that chart is below: UFFMAN Co HC2111 Terraces at High Mountain Chart Last Printed On: 07/19/2022 itll ett beeslii le: eataly [Telecieta4 pveltr-}| byes titty — AEG 04/18/2022 04/78/2022 Made ® Building Padi AEC 07/18/2022 # Building Pad 2 □□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□ © Building Pad 3 AEC 08/01/2022 # Building Pad 4 □□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□ © Building Pad 5 ABC ~—~—~—“CwBNIVD— * Building Pad 6 AEG 08/21/2022 © Building Pad 7 aC ogj2g2022—~” □□□ ——— #55 AEC 08/17/2022 + Storm AEC 08/22/2022 Water □□□□□□□□□□□□□□□□□□□□□□□□□

(See doc. 88-10, p. 3). As shown, Huffman “forecast” that AEC would complete general construction tasks for the Terraces no later than October 2022. Aside from this chart, Zimmer contends that Huffman provided AEC two other schedules that “fixed” AEC’s construction milestones. (See doc. 90, pp. 14, 17). One of those schedules applied to the Terraces project and mostly tracks the deadlines shown in the chart above. (See doc. 88-

11). The other schedule applied to the Boardwalk project. According to Zimmer, it included the following deadlines for AEC:

a. Building Al: September 12, 2022 b. Building A?: September 19, 2022 c. Building A3: September 26, 2022 d. Building A4: October 3, 2022 e. Building A5: October 10, 2022 f Sanitary Sewer: October 14, 2022 g. Building A6: October 17, 2022 h. Building A7: October 24, 2022 i. Building A8: October 31, 2022 j- Water System: November 9, 2022 k. Storm Drainage: April 18, 2023 1. Curbs/Roadways: February 17, 2023 (See doc. 90, p. 17; see also doc. 88-3). AEC’s owner and 30(b)(6) witness, Bennett Steele, stated that he had “never [seen] .. . or agreed to” the above schedule. (See doc. 88-2, pp. 326-27). But email correspondence between Huffman personnel reflects that the schedule received “some input” from an AEC employee named Don Byrd—someone Steele said that AEC employed to assist with “project management” and “pricing.” (See id., p. 43). Despite AEC’s apparent communication with Huffman regarding the schedules, Steele maintains that “AEC never agreed to a schedule and no schedule was ever made a part of” the subcontracts. (See docs. 86-1, p. 2; 86-2, p. 2). Both subcontracts show that an “Exhibit C” would provide a “progress schedule.” (See docs. 84-2, p. 150; 88-9, p. 28). But as best the court can tell, no filed version of the subcontracts includes an Exhibit C. And according to AEC, “no schedule was incorporated into Exhibit C.”

(Docs. 91, p. 4; 93, p. 5). B. The Relevant Contracts Two sets of contracts are important here: (1) Zimmer’s general contracts with Huffman and (2) the subcontracts between Huffman and AEC.
