The other indices are cost indices of the various activities in the construction and landscape architecture sectors listed under 6 items according to an approach towards analytical accounting: “cost of labour” now called “wages and charges”, “materials”, “equipment”, “energy”, “transport”, “miscellaneous costs”, similar to the “KLEMST” approach used by productivity economists (K = capital for “equipment”, L = labour for “labour”, E = energy for “energy”, M = materials for “materials”, S = services for “miscellaneous costs”, T = transport for “transport”).

The items are calculated according to a Lowe's aggregation-chaining technique. The index level of the item in the previous month is multiplied by the weighted mean of the variations in prices of the basic indices composing  the item.
