Common use of Volume Determination Clause in Contracts

Volume Determination. A. Project stands require an estimate of tree volume to be removed (marked and/or designated), using the accepted method of sampling, variable radius plot cruising typically with 10 BAF. Cruise systems standards are detailed in the Wisconsin DNR Timber Sale Handbook, (TSH) chapter 24. Tally of volume while marking is done is also acceptable. B. Adhere to sampling error standards as appropriate to stand size and complexity as described in Timber Sale Handbook, Cruise Accuracy Guide, chapter 23. C. Maintain sufficient records to provide an audit trail of how the project contract volume was derived, from cruise plan to the final calculation of net volume entered in the sale prospectus and Timber Sale contract. At a minimum, maintain the following information: 1. The original cruise design, including all changes to the original plan. Include the name of the person who prepared the plan or changes. 2. Cruise implementation notes that indicate what was actually done on the ground, such as: maps, tallies, plot locations used, plot location details and any deviations from the cruise design. 3. Cruise reports printed from cruise software, if applicable. 4. Work sheets that document any adjustments made to the volume shown on the cruise reports. 5. Traverse data and reports (GPS plot locations or azimuth-distance). Determine and record timber sale area volumes. At a minimum: a. Develop a cruise summary that lists volumes by the various sale units/blocks or by individual stands. b. Record total volume by product and species on DNR Form 2460-001. D. Utilization specifications for cruising will detail pulpwood volumes and sawlog volumes. Hardwood logs with a small-end diameter inside bark of at least 10.6” should be cruised and scaled as saw logs, and softwood logs with a small-end diameter inside bark of at least 7.6”should be cruised and scaled as saw logs. Sawlog volume estimates should be separated from cordwood volume estimates during cruising whenever there are at least 2 MBF of estimated sawlog volume on a sale. E. Units from cruise (MBF, cds, tons, other) must be detailed. Total sale volumes will be reported on DNR Form 2460-001 in units of cords and MBF. The Wisconsin DNR weight conversion factors will be used, TSH, chapter 12 to convert any weight scaled products. F. Comingling volume from cruise (e.g. 18 product code designation) can be done after all individual volumes are calculated. If products will be sold as a comingled product, the establishment notice (i.e. white portion of Form 2460-001) must report separate volumes by cords and MBF and the volume may be reported as comingled on the sold and final notice (i.e. the ▇▇▇▇ and blue portions of Form 2460-001). G. The Wisconsin DNR quality control and consistency measures are to conduct cruising evaluation for cruises conducted by consulting foresters. This will be done as a 5% check cruise by the Wisconsin DNR personnel.
