    This document requests approval for Variation Order No. 1 for a road widening project in Catanduanes due to changes in quantities. Some items will be deleted to prioritize important works, and quantities of excavation, subgrade preparation, aggregate base course, concrete pavement, and drainage structures will be increased due to corrections in computations and additions needed for continuity of flow. The cumulative variation is within the 10% limit allowed by contract terms. Approval is recommended to accommodate actual field conditions.

    cost. The addition/deletion of works should be within the general scope of the project as bid
    and awarded. A Variation Order may either be in the form of a Change Order or Extra Work

    The preparation of Variation Order is necessary due to the following:

    1. Deletion of Item A.1.2(2) - Provision of 4x4 Pick Up Type Service Vehicle for the
    Engineers on Bare Rental Basis and Item A.1.2(5) - Operation and Maintenance of 4x4
    Pick Up Type Service Vehicle for the Engineers to give priority to more important item of
    work for the responsive completion of the project.

    2. The increase/decrease in quantity is due to correction in the disparity on the original


    and actual quantity computation.

    3. Increased in quantity of Item 102(2) - Surplus Common Excavation, Item 105(1)a -


    Subgrade Preparation, Common Material, Item 200(1) - Aggregate Subbase Course and
    Item 311(1)e1 - Portland Cement Concrete Pavement (Unreinforced) - 0.28m. Thk., 14
    days due to the additional 1.5 meter shoulder of widening to be paved at station

    910mm. Dia., Class II RCPC, Item 600(7) - Curb and Gutter, Precast and Item 601(1) -

    construction of 910mm dia. Class II RCPC drainage structure at station 197+950 -
    197+997 (Right Side) which were not included in the original quantity computation but

    5. Decreased in quantity due to the removal of the construction of Item 505(2)a - Grouted
    Riprap, Class A at station 197+950 - 197+997 (Right Side) to divert the runoff of water
    away from the right side of the sidewalk to avoid flooding on the front area of the
