DIVISION 100General Provisions1
SECTION 101Definitions and Terms101.1 Active Voice and Imperative Mood1The Wyoming Department of Transportation has rewritten this edition of StandardSpecifications for Road and Bridge Construction with an emphasis on the active voice.In a sentence written in the active voice, someone acts on something. For example: “Theengineer will take a sample.” A similar sentence in the passive voice—“A sample will betaken”—would be unclear about who was responsible for taking the sample.2 Thisedition of Standard Specifications also makes use of the imperative mood. Theimperative mood is used when the party issuing an instruction and the party receiving itare already understood. In Standard Specifications, the department is stating itsrequirements or directions for work to the contractor; such statements have the same forceas if they contained the word “shall.” In an imperative sentence such as, “Pour theconcrete,” the department is indicating that it requires the contractor to pour the concrete.Before the award of a contract, imperative statements are directed to the bidder. After acontract has been awarded, imperatives are directed to the contractor.3The department will identify parties other than the bidder or contractor to whom it gives aresponsibility in Standard Specifications. In phrasings where the responsible party hasalready been clearly identified or in factual statements when it is not important to do so,the department may use the passive voice.101.2 Organization of Specifications101.2.1 General1 With the exception of Division 100, General Provisions, Division 800, Materials,and Section701, Electrical Devices, the sections of Standard Specifications are written in a five-partformat. Each section contains the following primary terialsEquipmentConstructionMeasurement and Payment2
Definitions and TermsSECTION 1012The subsections contain varying numbers of titled sub-subsections composed of higherand lower levels, as in an outline. For example, the equipment portion of Section 401, PlantMix Pavements and Recycled Plant Mix Pavements, includes the .3.2401.3.3.3401.3.4EquipmentMillingCrushingMixing PlantGeneral1. Cold feed control system2. Control Unit Batch PlantsDrum PlantsHauling Equipmentlower levels ofsubsection 401.3.3,Mixing Plant101.2.2 Hierarchy of Organization1The requirements of a subsection apply to subordinate subsections. In addition, and asshown at Subsection 401.3.3, Mixing Plant, in the example, many subsections begin witha lower-level subsection called “General.” The requirements of “General” subsectionsapply to the associated same-level subsections that follow. For example, the requirementsof Subsection 401.3.3.1, Mixing Plant, General, (which includes requirements about coldfeed control and control units), apply to Subsections 401.3.3.2, Batch Plants, and401.3.3.3, Drum Plants. They do not apply to the higher-level Subsection 401.3.4, HaulingEquipment.101.2.3 Titles (or Headings) and References1The titles or headings of sections and subsections are for convenience and do not bearon the meaning of the text.2Technical specifications and other documents referenced in the contract refers to theedition in effect at the time of award of the contract, unless otherwise specified.101.3 Measurement Units: Inch-Pound (U.S. Customary) Versus InternationalSystem (SI or Metric)1Standard Specifications shows sizes and measurements in both inch-pound (U.S.Customary) and International (SI or Metric) System units. Inch-pound units appear first,followed by a metric counterpart inside square brackets “[ ].”2When reading Standard Specifications, use the system of measurements used by thedepartment for the bid items on its “Proposal” (Form E-91). Do not mathematically convertthe units from one system of measure to another; the department does not intend itsmeasurement values to be equivalent and does not consider values interchangeable.3
