Observe all of the foregoing instructions to inspectors and:

First

See that the inspectors do likewise.

Second

Keep in close touch with every feature of all operations upon which the quality of the masonry depends.

Third

At any stage of the work there will be features which will require your particular attention and a larger share of your time. This will no doubt always apply also to certain foremen or certain inspectors. Some will require more watching than others.

Fourth

Study the characteristics of the foremen and inspectors in order to assign the inspectors to the best advantage. Some men who are mutually antagonistic would get on very well if paired off with others.

Fifth

Be present at any operation requiring special knowledge or skill, and direct it. as far as possible through the inspector assigned to it. If it is necessary that you take charge of the operation or actually perform some important detail, do so, remembering that practically all workmen of whatever grade are conscientious and will receive in a proper spirit any instruction tendered in the same spirit.

Sixth

Preserve your mental balance. Don't be stampeded over anything. Consult with the engineer over any ambiguous clauses in the specifications.

Seventh

Keep a diary the same as mentioned in Rule 15 to inspectors. Each night assemble in your diary all the numbers and figures kept by the various inspectors. See that they are reasonable and consistent. Compare the figures as to mortar and concrete turned in by the masonry inspectors with those kept at the mixer.

Regarding the figures as to stone, each inspector can readily keep the number of boxes of spalls delivered to and used by him. In case a night force is employed to deliver large stone upon the dam it may be necessary to have someone present to measure it. Stone coming on through the day can be measured by the inspector to whom delivered. Each stone should be measured and recorded thus 2 1/2 X 3 X 4 1/2, 2 X 3 1/2 X 5, etc. A stone can be measured and recorded in thirty seconds. Recording say twenty to forty stones will not interfere with the inspector's other duties. The desirability of keeping these notes requires some explanation.

For batches of mortar and concrete it is well to have a check on the account kept by the inspector at the mixer.

The relative number of yards of concrete and spalls is a direct measure of the efficiency of the force under a particular derrick. Up to a certain limit it is economical to put spalls into the concrete, although to be sure the question of whether it is to the interest of the contractor or your employer depends upon who is paying for the cement. For instance, 40 cu. yd. of concrete to 9 cu. yd. of spalls shows one thing and 38 cu. yd. of concrete to 11 cu. yd. of spalls shows quite a different thing. The latter derrick has substituted 2 cu. yd. of spalls for 2 cu. yd. of concrete at a saving of say $5.50.

Regarding the large stone: Though it would be well to keep separately the quantities going to each derrick if it can be done readily, still the purposes for which this information may be desired are such as to render this segregation of less importance.

A

As the mortar, concrete and spalls are accounted for it would be well to keep also the remaining element (stone) in order that your total may be complete in itself and furnish a rough check on the engineer's cross-sections, not only from time to time as for monthly estimates, but for the final estimate.

B

If your totals are carefully kept and show a proper correspondence with monthly estimates, they might in case of necessity be used as a basis for a monthly estimate.

C

Accidents are always possible, other notes might be lost or destroyed creating a situation such that the inspector's account might be very valuable if not invaluable. Unforeseen questions or contingencies might arise which could only be settled by such accounts.

D

Some clause in the specifications might easily render such accounts absolutely necessary. For instance, that material excavated from the quarry, or certain quarries, should be paid for at an excavation price if it was not used in the masonry. Again, quarry conditions might be such as to render impracticable any measurement of stone and waste by taking cross-sections. Under such circumstances it might be necessary to keep an inspector in the quarry to account in a similar manner for everything that went out of the quarry.

Eighth

As an inspector should cooperate with the foreman, so should the chief inspector cooperate with the superintendent. Study the larger conditions affecting the progress as well as quality of work, such as amount, condition, and capacity of plant, arrangement and proposed future arrangement of derricks, quality and quantity of quarry output, etc., not only to plan your own work intelligently, but to advise with the superintendent if occasion arises. You may have more time than the superintendent in which to study certain features, although the superintendent's province is quantity and yours quality, it will be to the advantage of the work if your relations are such that you can freely discuss with him all sides of any question.
