      Plaintiffs’ petition for writ of certiorari denied by the Supreme Court November 7, 1955.
    
   Laramoke, Judge,

delivered the opinion of the court:

Plaintiffs, contractors for the construction of the Veterans Administration Hospital, Beekley, West Virginia, were required by the contracting officer to install facing tile in the walls of the hospital’s boiler house and garage where the specifications called for “structural unglazed units.” It is plaintiffs’ position that this language permitted the use of cinder block. They claim the difference between the cost of installing facing tile and cinder block.

The plaintiffs, coadventurers, were successful bidders on the Veterans’ Administration Hospital at Beckley, West Virginia. On February 19, 1948, a contract was executed for construction of the hospital. The contract price was $4,975,123.

The Finish Schedule on the key sheet which formed part of the plans and specifications indicated that wall finishes 50 and 51 should be “struc. unglazed units.” Section 5-04 of the specifications stated that “structural unglazed units marked in Finish Schedule * * * shall be smooth unglazed units.” Smooth unglazed units are described in detail in section 5-05, where, in subsection (b) (2), it is provided that all smooth unglazed units shall be manufactured of fireclay, shall be free from cracks with a smooth, unbroken, natural-die finish, and shall be buff in color.

Addendum No. 1 amended section 4 which related to brick and structural tile to permit the use of cinder block as an alternative to structural clay tile. Section 5, entitled “Masonry: Structural Facing Units,” was not so amended.

Plaintiffs employed the Southern Fireproofing Company as subcontractors to construct the interior walls in the hospital, in the boiler house and garage, and in the pump and meter house. The work was in progress when Samuel F. Brown, defendant’s liaison engineer on the Clarksburg and Beckley hospital projects, discovered that cinder blocks were being installed in the walls of a basement room in the “Beckley” hospital. The Finish Schedule indicated that the walls of this room were to be “struc. unglazed units.” The discovery was the first indication Mr. Brown had that plaintiffs were interpreting the phrase “structural unglazed units” in the Finish Schedule to permit the use of cinder blocks. To save the additional expense and loss of time which would ensue had the completed wall structure been removed, plaintiffs were permitted to cover the exposed cinder blocks with “soaps” of matte glazed tile, a non-load-bearing facing tile, which gave the same appearance as the structural unglazed units specified. Plaintiffs made the necessary adjustments without protest and without claim for additional costs.

Thereafter, under the instruction of defendant’s resident engineer, who had been cautioned by Mr. Brown to make sure that the proper finish was used in the boiler house and garage where the Finish Schedule specified structural unglazed units, plaintiffs installed unglazed facing tile. They then claimed the sum of $19,284.29, representing the difference in the cost of installing facing tile over cinder block. The sum of $14,752.92 of this claim represented costs of the subcontractor. The claim was denied by the contracting officer and by the Army Board of Contract Appeals of the Corps of Engineers acting for the Secretary of the Army.

The question presented is whether the specifications here involved required the use of facing tile when “structural unglazed units” were called for on the Finish Schedule.

The pertinent provisions of the contract and specifications are as follows:

(16) Par. 5-02, Page 5-1. Delete the word “tile” appearing in the third and fifth lines of this paragraph and substitute the words “facing unit” therefor. *****

This case turns upon the meaning of the phrase “structural unglazed units.” Plaintiffs assert that the term excludes facing tile and insist that defendant’s requirement that facing tile be used where the plans and specifications called for “structural unglazed units” imposed an unauthorized additional expense upon the contractors for which defendant is liable. It is defendant’s position that the phrase “structural unglazed units” means facing tile.

A scrutiny of the contract and specifications makes the question of interpretation relatively simple. The Finish Schedule on the key sheet provides that wall finishes 50 and 51 shall be “struc. unglazed units.” Section 4 defines structural clay tile which admittedly is not facing tile and makes no reference to structural unglazed units. However, section 5 is headed “Masonry: Structural Facing Units” and in the first sentence of subsection 5-04 it provides that “Structural facing tile * * * shall be glazed and unglazed units as hereinafter specified.” The last sentence of subsection 5-04 states that “Structural unglazed units marked in Finish Schedule on drawings shall be smooth unglazed units.” Subsection 5-05 (b) (2) defines smooth unglazed units as follows : “All smooth unglazed units shall be type FTX, heavy-duty, select quality. The body of all smooth unglazed units shall be manufactured of fireclay. The face or faces that will be exposed when units are in place shall be free from cracks and shall have a smooth, unbroken, natural-die finish. The color of the faces shall be BUFF and shall conform to the approved samples. The finished face or faces of the smooth unglazed units shall be free from chips and other imperfections detracting from the appearance of the finished wall when viewed from a distance of 10 feet. * * *.”

Section 4 was amended to permit the use of cinder block as an alternative to structural clay tile. The evidence shows, as testified to by the witnesses Allen and Bingham, that either of these materials is appropriate when appearance is not a primary consideration. It is significant that no similar amendment was made to section 5, and cinder block could not be a substitute under this section.

It is clear that appearance was a primary consideration in section 5, especially in view of the fact that color was one of the requirements. Moreover, defendant’s exhibit 2 — Buff fireclay facing tile, which it required to be installed where structural unglazed units were specified — is the only tile meeting the color test and other specifications for smooth unglazed units. Further proof of this is the fact that before any question about the proper interpretation of section 5 was presented, Mr. Brown, defendant’s liaison engineer, discovered that plaintiffs were installing cinder block in a basement room where the Finish Schedule called for “structural unglazed units.” Plaintiffs were permitted to correct their error by covering the cinder block wall with matte glazed tile, a nonstructural facing tile, thereby 'producmg the same appearance that would have been provided had the structural unglazed units been used. Furthermore, plaintiffs installed the matte glazed tile without protest and without claim for additional costs.

It is conceded in plaintiffs’ brief that the smooth unglazed units described in subsection 5-05 (b) (2) are facing tile. “Structural facing tile” is the subject of subsection 5-04, providing that structural facing tile shall be “glazed and unglazed units as hereinafter specified.” Accordingly, structural unglazed units are thereinafter specified to be smooth unglazed units. Thus structural facing tile are smooth unglazed units as described in subsection 5-05 (b) (2) which plaintiffs concede are “structural unglazed facing tile.”

Eeduced to simple terms section 5 is headed “Masonry: Structural Facing Units.” Subsection 5-04 calls for structural facing tile to be installed and further says structural facing unglazed units shall be smooth unglazed units. Subsection 5-05 (b) (2) defines smooth unglazed units, which obviously could only include “facing tile,” for the reason, in addition to the requirements in subsection 5-05 (b) (2), the evidence shows that the question of “glazed” or “unglazed” could only apply to facing units.

Therefore, the phrase “structural unglazed units” could only mean facing tile under a proper construction of the contract and specifications and would require the installation of facing tile where structural unglazed units are specified.

When the defendant required that unglazed facing tile be used where the plans and specifications called for “structural unglazed units” it was correctly interpreting the plans and specifications and the plaintiffs are not entitled to recover the additional costs incurred in the installation of facing tile. We, therefore, dismiss plaintiffs’ petition.

It is so ordered.

Mabden, Judge; WhitakeR, Judge; Littleton, Judge; and Jones, Chief Judge, concur.

FINDINGS OF FACT

The court, having considered the evidence, the report of Commissioner Currell Vance, and the briefs and argument of counsel, makes findings of fact as follows:

1. Plaintiff T. A. Loving & Company is a corporation organized and existing by virtue of the laws of the State of North Carolina with its principal offices at Goldsboro, North Carolina.

2. Plaintiff Southeastern Construction Company is a corporation organized and existing by virtue of the laws of the State of North Carolina with its principal offices at Charlotte, North Carolina.

3. The plaintiffs are engaged in business as general contractors for the construction of buildings and other works, and insofar as this petition is concerned, were and are acting as joint contractors and coadventurers.

4. On November 24,1947, the office of the District Engineer, Huntington District, Corps of Engineers, U. S. Army, issued an invitation for bids for the construction of a Veterans’ Administration Hospital at Beckley, West Virginia. The invitation was designated Serial No. W-46-022-eng 48-78 and was accompanied by specifications and drawings.

5. Plaintiffs formed a joint venture to undertake the performance of the general contract for the construction of the hospital at Beckley, entered their bid and the same was accepted. On February 19, 1948, Contract No. W-46-022eng-1476 was executed between the plaintiffs and the United States for the construction of the Veterans’ Administration Hospital and appurtenances, Beckley, West Virginia (except elevators, dumbwaiters and quarters). The contract price was $4,975,123.

6. The controversy in this case relates to the requirements of the contract and specifications for the finish of the walls in the garage and boiler house. This actual work was performed by a subcontractor, Southern Fireproofing Company, whose subcontract is in evidence as plaintiffs’ Exhibit 2.

7. The portions of the specifications involved in the decision of the issue are set out below:

9. Additional addenda were issued on January 6, 1948, and January 26,1948, but did not alter the specifications in any way material to this case.

10. The contract contained the standard clauses, particularly covering changes and disputes concerning questions of fact.

11. The plaintiffs and the subcontractor had embarked upon performance of their respective contracts when it was discovered by the Government’s liaison engineer on the Beck-ley and Clarksburg jobs, Samuel F. Brown, that cinder blocks were being used where finish schedule No. 50 on the key sheet called for “Struc. Unglazed Units.” This work had been done in a basement room marked B061 of the main building, and its discovery by Mr. Brown was the first indication he had that the contractor was so interpreting the requirements of the finish schedule and the specifications. Bather than have the completed structure torn out, plaintiffs were allowed to cover the cinder block with matte glazed tile (a facing tile), which produced the same appearance that would have been provided had the structural unglazed units called for been used. Plaintiffs made the necessary adjustments without protest and without claim for additional costs.

12. Following his discovery that cinder block had been used where structural unglazed units were specified, Mr. Brown cautioned the Government’s resident engineer to make sure that the proper finish was used in the garage and boiler house where the finish schedule required structural unglazed units to be installed. Accordingly, the resident engineer instructed the plaintiffs.

13. Thereafter, plaintiffs placed unglazed facing tile in the areas designated on the plans to receive Finish 51. They then applied to the contracting officer for additional compensation in the amount of $19,284.29, representing the difference in the cost of installing facing tile over cinder block.

14. Plaintiffs’ claim in the sum of $19,284.29 for the additional costs, together with overhead and profit to the subcontractor and the plaintiffs, involving the use of facing tile as compared with cinder block, is itemized as follows:

The actual costs of $14,752.92 to the subcontractor are established by the proof. The other items are calculations therefrom.

15. Said claim was denied by the contracting officer, and also denied on appeal to the Army Board of Contract Appeals of the Corps of Engineers, as the representative of the Secretary of the Army.

16. Plaintiffs have testified that they have acknowledged liability to the subcontractor for its part of the claimed recovery, as shown in finding 14 above, at least to the extent of any recovery which may be secured.

17. It is admitted that the finish indicated for the walls of the cellar and boiler house is No. 51. By reference to the key sheet, plaintiffs’ Exhibit 8, and the finish schedule therein set forth, it is noted that wall finish 51 is described as “Struc. Unglazed Units”. The defendant calls attention to the fact that these three words used together appear only in Section 5-04 of the specifications under the general title of Section 5, to wit, “Masonry: Structural Facing Units”. It is not contended by the plaintiffs that such words in Section 5-04 should not have been identified as those called for on the key sheet.

18. Plaintiffs further concede that in the same sentence of Section 5-04, structural unglazed units are identified as smooth unglazed units. However, plaintiffs say that the expression “smooth unglazed units” is not sufficiently definite to indicate facing tile, and can comprehend concrete cinder block. However, there is a special section of Section 5, designated as 5-05 (2), giving a detailed description of smooth unglazed units, which clearly sets forth requirements which designate facing tile and are not satisfied by concrete cinder block.

It is conceded that the full self-contained description of the finish which plaintiffs were required to install in the disputed areas is “structural unglazed facing units.” However, the expression “structural facing units” would not be sufficiently definite, because such units might be either glazed or unglazed. In the trade the expression is sometimes abbreviated to omit the word “facing”, and the designation may be either “structural glazed units” or “structural unglazed units”. It appears that the use of the word “unglazed” indicates in the trade that a product is called for which might in some instances be either glazed or unglazed, and is not understood to apply to a product such as concrete cinder block.

CONCLUSION OE LAW

Upon the foregoing findings of fact, which are made a part of the judgment herein, the court concludes that as a matter of law the plaintiffs are not entitled to recover, and the petition is therefore dismissed.
