Two-inch rough pine boards were used to make the troughs for the girders, while 1-in. rough boards were used for the floors. These were all supported by 3×4-in. pine scantlings. This lumber cost delivered $17.50 per M. ft. B. M. Carpenters did all the framing, and erected it with the help of laborers. All the carrying of the lumber was done by laborers. This reduced the cost of the work, as the laborers' wages amounted to one-third of the whole cost. As soon as the forms were all in place, which was before the mixing of concrete commenced, the carpenters were discharged. The cost per cubic yard for forms was:
| Lumber | $2.82 |
| Nails | .05 |
| Labor, carpenters | 1.24 |
| Laborers | .62 |

The tearing down of the forms was done entirely by laborers at a cost of 61 cts. per cu. yd.
On concrete work it is also advisable to keep the cost of forms per thousand feet board measure, so as to have such data for estimating on new work. The cost per M. ft. on this job was:
| Lumber | $17.50 |
| Nails | .30 |
| Labor, carpenters | 7.65 |
| Laborers | 3.85 |
| Tearing down | 3.80 |

The concrete was mixed by hand, water being carried in buckets from the creek. Ten to twelve men were worked in the gang under a foreman, and the concrete was wheeled from the mixing board to the forms in wheelbarrows. The mixture was made wet enough to run. The cost per cubic yard for the girders in detail was as follows:
| Foreman | $0.41 |
| Preparing for mixing | 0.14 |
| Cleaning out forms | 0.07 |
| Handling materials | 0.30 |
| Handling and placing steel | 0.40 |
