800.01 General.
Division 800
MATERIALS SECTION 800 MATERIALS
800.01 General.
All materials used in th e work shall be new, unused material that will meet the requirements described in this Division unless the same are altered by specific requirements of any Section of these Specifications, Special Provisions , or by modifying notes on the plans. All materia ls shall also meet the requirements of applicable portions of Section 106 which will supplement the requirements of this Section. All tests shall be in accordance with the current Departmental testing schedule.
800.02 Inspection Arrangements.
a.Contractors' Notification . It shall be the duty of the Contractor to notify the Engineer of the source of the various materials required for each project. This notice shall be received sufficiently in advance of any shipment of materials so that inspection may be arranged at the producing plant if the Engineer so elects.
b.Plant Inspection . Whenever the quantity of materials warrants such an arrangement and/or it is economically advantageous to the Department, the inspection of materials at the original o r immediate source of supply will be made. However, the Department is under no obligation to the Contractor to inspect materials until it arrives at the site of the work. In general, all aggregates, soil, brick, reinforcing and structural steel, bituminous materials, timber, lumber, piling, and posts which are to become a part of the completed work will be inspected at the point of production. For timber, lumber, piling, and posts which are to be given preservation treatment, this inspection will be perform ed at the treating plant in conjunction with inspection of the treating process.
c.General Details .
1.For lumber and timber products, the producer shall have sorted his stock and shall have separated a sufficient quantity of material to insure that all of each item for inspection is available before the Inspector is called. In the event that part of the shipment is rejected because of failure to meet the specification requirements, the producer shall furnish other stock to replace the rejected items.
2.Should the quantity of any material rejected for failure to meet specification requirements amount to 20 percent or more of the material inspected and tested at that time, the inspection operation will be suspended until the producer shall have regraded hi s stock or revised his production methods to produce material uniformly conforming with the specifications. When sampling stockpiles of aggregates, base materials, etc., the average of all samples must be within the gradation band required for the size ag gregate specified. In no case will stockpiles be acceptable if more than 20% of the total samples fall outside the gradation band. In addition, any failing sample must be within 20% of the range specified for any designated sieve.
3.In case the stock has not been properly prepared or separated before calling an Inspector, or in case of delay in replacement of rejected material, the extra inspection cost occasioned by such delay will be charged against the Contractor for whom the material is being produced and will be deducted from any sums due or which may become due the Contractor.
4.Where a Contractor's producer or jobber requests inspection of material for warehouse stock or for use in plants where stocks of materials inspected and accepted for use in h ighway construction or maintenance cannot be kept separated from materials which are to be used on other work, the cost of inspection of those materials which have been approved for highway work, but are later diverted to other uses not connected with the Department's highway construction or maintenance, will be charged to the Contractor who requested such inspections.
