Contracts - Contract PDF Present

Contracts and modifications awarded by the City of Chicago since 1993. This data is currently maintained in the City’s Financial Management and Purchasing System (FMPS), which is used throughout the City for contract management and payment.
Legacy System Records: Purchase Order/Contract Numbers that begin with alpha characters identify records imported from legacy systems. Records with a null value in the Contract Type field were imported from legacy systems.
"Comptroller-Other" Contract Type: Some records where the Contract Type is "COMPTROLLER-OTHER" are ordinance-based agreements and may have start dates earlier than 1993.
Depends Upon Requirements Contracts: If the contract Award Amount is $0, the contract is not cancelled, and the contract is a blanket contract, then the contract award total Depends Upon Requirements. A Depends Upon Requirements contract is an indefinite quantities contract in which the City places orders as needed and the vendor is not guaranteed any particular contract award amount.

Blanket vs. Standard Contracts: Only blanket contracts (contracts for repeated purchases) have FMPS end dates. Standard contracts (for example, construction contracts) terminate upon completion and acceptance of all deliverables. These dates are tracked outside of FMPS.

Negative Modifications: Some contracts are modified to delete scope and money from a contract. These reductions are indicated by negative numbers in the Award Amount field of this dataset.

自1993年以来，芝加哥市所签发的合同及其变更记录。该数据集目前由市财政管理及采购系统（Financial Management and Purchasing System，简称FMPS）维护，该系统广泛应用于全市，用于合同管理与支付处理。历史系统记录：以字母开头的采购订单/合同编号标识来自历史系统的记录。合同类型字段值为空值的记录亦来自历史系统。
“会计-其他”合同类型：部分合同类型为“COMPTROLLER-OTHER”的记录为基于法规的协议，其起始日期可能早于1993年。
依据需求而定合同：若合同授予金额为0，且合同未被取消，且为总括合同，则合同授予总额取决于需求。此类合同为不定数量合同，市方根据需要下订单，供应商不保证获得任何特定的合同授予金额。
总括合同与标准合同：仅总括合同（反复购买合同）在FMPS中记录结束日期。标准合同（如建筑合同）在所有交付成果完成并被接受后终止，这些日期的跟踪在FMPS之外进行。
负面变更：部分合同经过变更以削减合同范围和资金。此类减少通过本数据集中授予金额字段中的负数表示。
