2.Any gap that requires no Work, provided the gap is at least 50 feet long when measured parallel to the center line and contains at least 2,500 square feet. Isolated areas of less than 2,500 square feet that require Work lying between areas excluded from measurement will be counted as having 2,500 square feet. If these isolated areas occur intermittently, the final measurement shall not exceed the total area containing the several isolated areas when measured as continuous. Clearing and grubbing may be combined in the Proposal. If the Proposal calls for such combined Work to be measured “per acre”, the measurement methods described above will apply. If the Proposal designates such combined Work as “lump sum”, the Contracting Agency will not base payment on any unit of measurement.
