The material to be disposed as unsuitable material shall not be wasted until approved or directed in writing by the Engineer.
Designed and developed by Vietkent. Soft rock shall comprise weathered rock, sandstone, limestone and such materials which, in the opinion of the Engineer, can nxd excavated by picking, ripping or other similar means without resorting to blasting.
No payment will be made for the gxd from unapproved design changes. No allowance will gxd made for classification of different types of material or soil encountered. Soil that cannot be properly compacted in accordance to Specification requirements or as determined by the Engineer.
The quantity of Common Excavation to be paid for shall be the number of cubic meters of material acceptably excavated in accordance with this specification and approved by the Engineer, based on field measurements. Duc asks for advice on how to proceed the above case?
The contract form is adjustable unit price-based, specifying that the contract price can be adjusted when there are changes in regimes, policies by the Government and material price, or when there are changes in construction price indices announced by state agencies. Regulation on finalization of adjustable unit price-based contract.
Unsuitable material shall be removed and disposed of in waste areas provided by the Contractor in such manner as to present a neat appearance and not to obstruct drainage to any highway nor to cause injury to highway works or property. The topsoil shall be completely removed to the required depth from any designated area prior to the beginning of regular excavation or embankment work in the area and shall be kept separate from other excavated materials for later use.
Boulders shall comprise solid pieces of rock that are weathered on all faces boulders that are between 0. The waste areas poposed by the Contractor shall be permitted by the relevant state and local authorities and shall ensure all requirements of environmental control and protection as specified in the Section of the General Specification. This plan shall be continuously updated, in weekly basis, in accordance with the progress of the works until completion of the roadway excavation.

Variation, delays or failing on this 11776 and the application of countermeasures to correct respective defects will be evaluated by the Engineer in accordance with the statements of the Conditions of Contract and will be charged to the Contractor expenses without any time extension.
Excavation operations shall be conducted so that material outside of the limits of slopes will not be disturbed. If it becomes necessary for the Contractor to locate or relocate any waste areas, the Contractor shall obtain previously the approval from the Engineer to commence with the operation for spreading any waste.
Surplus material to the amount required for the construction of the embankment, provided however that it is not material rendered surplus by reason of the Contractor having opened borrow pits solely for his bzd convenience. The price adjustment per the signed contract is consistent with regulations applicable to construction contracts.
This rock class includes the type of rock grade 4 described in the Table of Rock Classification applying for rock v; in the Norm of Cost Estimation for Construction enclosed with the Document No. Roadway excavation classified as hard rock shall include only such roadway excavation that in the opinion of the Engineer is not practicable without the use of pneumatic tools or drilling and blasting operations.
All excavations shall be finished to reasonably smooth and uniform surfaces. The removed topsoil shall be transported and deposited with the height not in 17776 of 3m to avoid disturb to natural ground in storage piles at locations previously prepared by v Contractor and approved by the Engineer. No 17776 shall be wasted without previous quantification by the Contractor and respective approval by the Engineer.
The quantity of Unsuitable Material, excavated according to this Specification section and approved by the Engineer, shall be measured in cubic meter. The measurement shall include unavoidable over-breakage due to slides when not attributable to carelessness of the Contractor. The Ministry of Construction answered: This soil class includes all the types of soil excavation by hand and by equipment described in the Tables of Soil Classification applying for soil excavation, transportation, filling works by hand and machine in the Norm of Cost Estimation for Construction enclosed with the Document No.
The material shall be measured in the original position in the natural ground after Site Clearing and Grubbing. Materials having hazardous chemical or physical properties. Soil Excavation will be in a single unit price for payment regardless of bxxd soil nature, existing conditions or geological classification. The Activity Value shall be measured as the ratio: However, boulders that although exceeding the above stated volume can be disposed out of the Project area by using common equipment for transportation without necessity of blasting or pulverization shall not be considered as rock excavation.
If in the adjustable unit price-based contract there is a clause specifying that the contract price can be adjusted when there are changes in regimes, policies by the Government and material price, or when there are changes in construction price 17766 announced by state agencies, the adjustment of contract price per norms announced by the Ministry of Construction is acceptable. Materials below the natural ground surface in embankment areas and in excavation areas below the 176 plane or other limits shown on the Drawings, or as designated by the Engineer, that is unsuitable for the planned use.
After approving the project design, construction drawing, cost 177, the investor organized bidding to sellect the construction contractor. Hard rock shall not include material which, in the opinion of the Engineer, can be loosened or excavated with standard equipment tractors or backhoe.
If in the adjustable unit price-based bxxd does not exist a clause specifying that the contract price can be adjusted when there are xbd in vpp, policies by the Government and material price, or when there are changes in construction price indices announced by State bodies, the adjustment of contract price per norms announced by the Ministry of Construction is not acceptable. The actual excavation volume 17776 be computed from the average cross section areas bounded by the ground lines after clearing and grubbing, the designed slope lines, and plane after excavation of unsuitable material.
Boulders that are less than the stated volume shall be measured as soil excavation. Measurement of boulders will taken as the maximum dimension along the longest axis of the boulder length multiplied by?
However, the project still used some norms per Official Letter No. Boulders that exceed the above stated volume and cannot be pulverized without the use of pneumatic tools, drilling and blasting operations, or by standard tractor or backhoe, shall be classified as Hard Rock.
Payment for such compaction shall deem to be included in the unit rate for excavation. Waste areas shall be left in a smooth, neat and drainable condition, as required by the Engineer, and all waste material shall be placed in such manner that adjacent property will not be damaged or endangered.
The payment and finalization of construction contracts shall be done per the content of the contracts signed between parties and following state regulations applicable to contracts. Finished excavated surfaces that are exposed to surface run-off water shall be sufficiently smooth and uniform, and have sufficient slope, to ensure the free drainage of the surface with no ponding.
