Vertical and horizontal adjustment Clause Samples
The 'vertical and horizontal adjustment' clause defines how changes in quantities or scope are managed within a contract, particularly in construction or supply agreements. Vertically, it addresses adjustments to the total amount of work or value for a specific item, while horizontally, it covers changes across different items or sections of the contract. For example, if the required quantity of a material increases or decreases, or if work needs to be shifted between different sections, this clause outlines how pricing and obligations are recalculated. Its core function is to ensure that both parties have a clear, fair mechanism for handling changes, thereby reducing disputes and maintaining contract balance.
Vertical and horizontal adjustment. If the "cut-off" complies with the quality requirements of paragraph 2. of this annex, the beam adjustment may be performed instrumentally. Figure 1

2.3.1. Vertical adjustment Moving upward from below the line B (see Figure A5-III), a vertical scan is carried out through the horizontal part of the "cut-off" at 2.5° from V-V. ▇▇▇ ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ (▇▇▇▇▇ ▇▇ (▇▇▇ ▇) / ▇▇▇ = 0) is determined and positioned on the line B situated one per cent below H-H.

3.1. Vertical adjustment Moving upward from below the line B (see figure 2 below), a vertical scan is carried out through the horizontal part of the “cut-off” at 2.5° from V-V. The inflection point (where d2 (log E) / dv2 = 0) is determined and positioned on the line B situated one per cent below H-H.
3.2. Horizontal adjustment The applicant shall specify one of the following horizontal aim methods:
(a) The “0.2 D line” method (see figure 2 below). A single horizontal line at 0.2° D shall be scanned from 5° left to 5° right after the lamp has been aimed vertically. The maximum gradient “G” determined using the formula G = (log Eβ - log E(β + 0.1°)) where β is the horizontal position in degrees, shall not be less than 0.08. The inflection point found on the 0.2 D line shall be positioned on the line A.

(b) The “3 line” method (see figure 3) Three vertical lines shall be scanned from 2° D to 2° U at 1°R, 2°R, and 3°R after the lamp has been aimed vertically. The respective maximum gradients "G" determined using the formula: G = (log Eβ – log E(β + 0.1°))
