A DIVISION OF GENERAL DYNAMICS CORPORATION GIIIIIIIID 300 W. WASHINGTON ST., CHICAGO Phone 726-3800 Area Code 312
Complaint to stand, the Appellate Court held that the contractor was under an implied obligation to perform the work in a reasonable, careful manner, and therefore the owner could recover against the contractor, although there was no written "Hold Harmless Agreement." It is interesting to note that in this case the contractor not only paid the plaintiff under the Workman's Compensation Act, but he was under a duty to reimburse the owner for any judgment which the plaintiff might recover from the owner.
It is this doctrine of law which has given rise to the adoption in most heavy construction work of indemnity contracts on a broader and broader basis so that there will be some explicit wording as to the indemnity, since almost any contractor who can award such work involving hundreds of thousands of dollars, in many instances will sign almost any form of indemnity agreement in order to secure the contract.
In view of the court's liberal interpretation of the Hold Harmless Agreement, it is necessary for you to make sure, beyond a shadow of a doubt, that the language clearly and unequivocally spells out your duties under the agreement. If you do not, you may be ordered by the court to indemnify an owner for an injury caused solely by his negligence, even though it is your understanding that the agreement did not provide for this.
Another important question in considering construction contracts is the liability of a contractor for defects in the work resulting from faulty plans or specifications. As a general rule, a contractor is not liable because, when he has performed the work in accordance with the plans and specifications, he has performed his contract. If defects develop in the work, it is not the fault of the contractor but that of the party who prepared the plans and specifications.
Next month's issue of masonry will carry Mr. Peterson's remarks on this important question.
New Rating For Vermiculite
Vermiculate protection for an economical new steel joist and roof system has earned a two-hour fire rating from Underwriters Laboratories, Inc., Chicago.
The assembly consists of a two-inch thickness of 1:6 mix vermiculite concrete over a corrugated steel deck supported on bar joists. Built-up roofing was strip-mopped to the concrete.
The ceiling below the joists has 4 inch furring channels tied to the bottom chords of the joists, paper-backed wire lath, a 14 inch thick base coat of 1:2 vermiculite-gypsum plaster, and a ½ inch thickness of vermiculite acoustic, Type Z, for sound conditioning. Type Z is a new formulation.
Six 2 ft. by 4 ft. light trollers and two 12 inch diameter air-diffusers were incorporated in the ceiling and remained intact throughout the fire, hose-stream, and double load tests. The openings for troffers and air-diffusers constituted 25 per cent of the ceiling area.
Insurance rating bureaus point out that important savings in the cost of premiums can be made with two-hour fire-rated construction compared with non-rated "incombustible" construction.
