[1] Plaintiffs appeal does not bring forward its second Assignment of Error with respect to that portion of the judgment denying its second claim for relief. We deem that plaintiffs second Assignment of Error is abandoned. Rule 28(a), N.C. Rules App. P. Plaintiffs first and third Assignments of Error are both with respect to plaintiffs first cause of action. The first question presented for our review by way of plaintiffs appeal is whether the trial court erred in its conclusion of law that the Standard *267Specifications and Special Provisions incorporated by the parties contemplated the construction of barrier rails by the use of a fixed form.
When the trial judge sits as the trier of fact the judgment rendered will not be disturbed on the theory that the evidence did not support his findings if there is competent evidence to support the judgment. Whitaker v. Earnhardt, 289 N.C. 260, 221 S.E. 2d 316 (1976). However, the record may clearly reveal that the court erred in its legal conclusions from the facts. H. V. Allen Co. v. Quip-Matic, Inc., 47 N.C. App. 40, 266 S.E. 2d 768, cert. denied, 301 N.C. 85, 273 S.E. 2d 298 (1980).
The conclusions of law which plaintiff excepts to are as follows:
Based upon the foregoing finds (sic) of fact, the Court concludes as a matter of law that the Standard Specifications and Special Provisions incorporated by the parties in their contract control the disposition of this controversy; that these documents contemplated the construction of barrier rails by the use of fixed form; . . . that under the specifications the DOT [defendant] was fully authorized to require a reduction in price when the construction method for the barrier rails was to be changed at the request of Hardaway.
The court, pursuant to the parties’ stipulation, found as fact the following:
12. The contract specifications for this project include the ‘North Carolina Department of Transportation — Raleigh — Standard Specifications for Roads and Structures,’ dated July 1, 1978 (‘Standard Specifications’) as well as all special provisions in the document entitled, ‘Contract and Contract Bonds for Project No. 8.1112203, F75-5(13)’ (‘Contract’).
The two sections of the contract, which the court quotes in its pertinent findings of fact are section 108-5 of the Standard Specifications and the special provisions section of the contract entitled “Concrete Barrier Rails.” Neither section 108-5 nor the special provisions quoted by the trial court state that cast-in-place forms are required as a method of constructing the barrier rails. The trial court found as fact the following:
*26814. The plans and specifications do not state anywhere that ‘slip-forming of the concrete barriers will not be permitted.’ The plans and specifications do not state anywhere that ‘slip-forming of the concrete barrier rails will only be permitted at a $7.00 per lineal foot credit to the North Carolina Department of Transportation.’
Our review of the entire language of the contract reveals that the contract language was explicit when the drafters intended that no other methods were to be used in other phases of the construction project. For example, subsection 1 of the section entitled “Reinforced Concrete Deck Slab” states “Plans for the concrete deck slab are detailed for the use of metal stay-in-place forms; however, the contractor shall have the option of constructing a cast-in-place slab using removable forms, or a cast-in-place slab using precast prestressed concrete panels in the prestressed concrete girder spans.” An even more convincing example of the way this document was drafted may be found in subsection 3 entitled “Construction methods.” “Curing methods for the concrete will perform to the standard specifications except when using pre-stressed concrete panels the cast-in-place concrete shall be cured by the water method as specified in subarticle 42047(b) of the standard specifications. No other methods will be allowed” (Emphasis added.) The language we are concerned with in the section entitled “Concrete Barrier Rails” is as follows:
The quantity, measured as described above, will be paid for at the contract unit price per lineal foot bid for concrete barrier rail, which price and payment shall be full compensation for all materials, admixtures, forms, form lining, false work, curing, surface finish, tools, labor, equipment and incidentals necessary to complete the item.
At the Contractor’s option he may line the inside of his forms the roadway face of the barrier rail with an absorbent material that meets the approval of the Head of Structure Design, or he may use forms with no lining and afterwards, the roadway face of the barrier rail with an absorbent material that meets the approval of the Head of Structure Design, or he may use forms with no lining and afterwards, the roadway face of the barrier rails shall be given a Class II surface finish in accordance with the specifications.
*269 In the event the Contractor uses a lining in his forms for the roadway face of the barrier rail, and after removing the forms, the surface on the roadway face of the barrier rail is not acceptable in the opinion of the Engineer, the Contractor will be required to give this surface a Class 2 surface finish in accordance with the specifications.
(Emphasis added.) These excerpts from the contract, recited by the court in its findings of fact, refer to “Forms” only. There is no specification of fixed forms. The trial court may have intended to find as fact that “forms” referred to fixed forms. However, in the absence of such a finding, our review of the findings of fact do not disclose any support for the court’s conclusion of law that the contract contemplated fixed forms as the only acceptable method of construction. The contract does not specify fixed forms as the only method of construction. A mere recitation of the contractual terms in the findings of fact is insufficient to support the court’s conclusion of law that the contract contemplated the use of fixed forms.
[2] The court’s findings of fact contain an excerpt from section 108-5 as follows:
When the contract specifies that the construction be performed by the use of certain methods and equipment, such methods and equipment shall be used unless others are authorized by the Engineer. If the contractor desires to use a method or type of equipment other than those specified in the contract, he may request authority from the engineer to do so. The request shall be in writing and shall include a full description of the methods and equipment proposed to be used and an explanation of the reasons for desiring to make the change. If approval is given it will be fully responsible for producing construction work in conformity with contract requirements. If, after trial use of the substituted methods or equipment, the Engineer determines that the work produced does not meet contract requirements, the Contractor shall discontinue the use of the substitute method or equipment and shall complete the remaining construction with the specified methods and equipment. The contractor shall remove the unsatisfactory work and replace it with work of specified quality, or take such other corrective action as the *270engineer may direct. No change will he made in basis of payment for the construction items involved nor in the completion date as a result of authorizing a change in methods or equipment under these provisions.
(Emphasis added.) We deem that section 108-5 is controlling in the case sub judice. Section 108-5 provides for instances where the contract has not specifically required a method of construction, which is the situation that we must address.
Slip-forming as a method of construction is not specified in the contract. Plaintiff indicated its desire to use slip-forming to defendant. Defendant approved plaintiffs use of slip-forming as a method of construction. The work done by plaintiff met the contract requirement and as the trial court found as fact the work was done to “the satisfaction of all.” Therefore, the supplemental agreement that changed the basis of payment, which plaintiff executed under protest, is at variance with the terms of the agreement. Section 108-5 unequivocally states that “No change will be made in basis of payment for the construction items involved.” The contract contemplates payment “at the contract unit price [$42.00] per lineal foot bid for Concrete Barrier Rail, which price and payment shall be full compensation for all . . . forms.” It is apparent that the end result of the contract measured by lineal feet is the basis of payment upon which the contract is based. Plaintiff fulfilled the pertinent terms of the contract by erecting 8,537.8 feet of concrete barrier rail and is entitled to the contract price of forty-two dollars ($42.00) per lineal foot of concrete barrier rail. Plaintiff is entitled to recover the $59,764.60 deducted by defendant as a credit pursuant to the supplemental agreement. For the aforementioned reasons the judgment must be reversed and the matter remanded to the trial court for entry of judgment for plaintiff not inconsistent with this opinion.
Reversed and remanded.
