FOREWORD

This document has been prepared to assist Metropolitan Transit Authority (METRO) personnel in the preparation of Equipment Specifications, Data Sheets, Scope of Services and Statements of Work.

INTRODUCTION

This document provides guidelines and recommendations for developing the format and content of a specification, data sheet, Scope of Service or Statement of Work for the following, but not limited to:

Statements shown in light type provide instruction and clarification for a specification or Scope of Service paragraph, and statements in bold type are suggested wordings for the content of a paragraph.

Each specification, data sheet or statement of work statement adopted from this document should be carefully reviewed and modified as needed prior to being incorporated into a specification. The scope of service statements are typical examples for services required and should only be used as a guide.

The use of the word Contractor is synonymous with the words vendor, supplier, seller or bidder.

Commercial-type requirements such as warranty provisions, cost information, delivery information and method of payments should not appear in a technical specification or scope of service since they will be specified in other documents provided by the Office of Procurement.

OBJECTIVE OF A SPECIFICATION OR A SCOPE OF SERVICE

The objective of a specification, data sheet or scope of service is to communicate to Contractors and Procurement personnel what is required and also provide the basis for quality assurance to determine if the Contractor has met the requirements of the contract or purchase order. The specification or scope of service must be written in clear, unambiguous and precise language to communicate effectively what is required. Remember, the Contractor has total responsibility for the work after receipt of order.

PROJECT MANAGER/USER RESPONSIBILITY TO PROCUREMENT

Upon preparing an Invitation for Bid (IFB), Procurement with assistance from the Project Manager or user has total responsibility for preparing the following sections:

Bidding Requirements

Forms for Bidding

Proposed Contract

The Project Manager or user should input to Procurement any information that does not apply to the Specification or Scope of Service via memorandum and the information will be included in the appropriate document. Examples of this type of information are as follows:

This shall also be true for Request for Proposals (RFP) or Purchase Orders.

The Specification or Scope of Service of the IFB, is the total responsibility of the Project Manager or user with the assistance of Contracts. The Specification or Scope of Service should be provided to Procurement double-spaced and in the final format. To be consistent with the typing of the entire contract, the specification or scope of service should be typed with a 10 pitch courier print wheel and margins of 8 and 77.

The ultimate goal is for the Project Manager or user to furnish to Contracts a specification or scope of service that can be utilized in a bid package without discussions with the Project Manager or user.

PART IV PURCHASE DESCRIPTION

The Statement of Work (SOW) is a special category of a specification that is used when contracting for services and equipment. The SOW outlines the nature of the work, the level of effort required and the anticipated results of the work, rather than detailed technical specifications of a particular item. For services and equipment that can be adequately described with less data than that contained in the Six-Section Equipment Specification, Scope of Services or Brand Name or Equal Equipment Specification/Data Sheet Format, you can write a short SOW. This approach is usually reserved for Off-the-Shelf hardware or commonly available services.

When writing a SOW, you must utilize you special knowledge of the subject in deciding the content of the SOW. The key elements are the same as those for any Specification or Scope of Service, with the added requirement that you must state when and where the work is to be performed. The SOW must deal with the following basic questions:

When the SOW has answered the above questions, it is essentially complete.
