ARCHITECTENGINEER SERVICES

I. SCOPE OF WORK

A. Architect-Engineer (A-E) services are required to provide work normally accomplished by A-E firms. This includes varying levels of work from providing preliminary plan documents through complete detailed design for maintenance, repair, alteration, and new construction projects that require expertise in architecture and the civil, structural, mechanical and electrical engineering fields.

B. If complete design documents are requested, the A-E shall furnish all services, materials, supplies, and supervision required to fully investigate and design each project. The services required for each project will be negotiated under a separate delivery order and detailed in a statement of project scope.

C. The A-E shall furnish the services of a qualified construction inspector as negotiated under a separate delivery order.

II. STATEMENT OF SERVICES

A. The design of architectural, civil, structural, mechanical, electrical and other engineering features of the work shall be accomplished or reviewed and approved by an architect or engineer registered to practice in the particular professional field involved. The final drawings shall be stamped and signed by a principal of the firm registered in engineering or architecture.

B. Design services performed by the A-E shall be accomplished as follows:

1. Upon request A-E will be given copies of available as-built drawings in the electronic format in which they are currently stored (.tif, .pdf or .dwg). Hard copies of as-built drawings will not be provided by Little Rock AFB.

2. Construction Drawings: Drawings shall be 24" X 36" and shall be accomplished in AUTOCAD (latest version). Drawings shall be accurate and in sufficient detail to enable proper and satisfactory construction of the entire project. Designs and construction drawings requiring contractor site visits will not be acceptable. The quality and workmanship of the drawings shall permit clear and legible reproductions. Reference drawings may be used only with specific permission of the Contracting Officer (CO) and shall not be used as substitutes for demolition, plan, and detail drawings. The A-E will be provided with a border and title block. The border shall be inserted in paper space at a base point of 0,0 and with a scale of 1. This border shall not be modified except with specific permission of the Contracting Officer. The drawings shall be designed using model space at full scale. A-E shall use roman simplex as font style unless approved by Contracting Officer. Text shall be in the same drawing space as the object the text is describing. For Example, text describing an object that is drawn in model space shall also be placed in model space. A-E shall follow Tri-Services layer naming standards. Drawings shall be capable of being opened and edited in AutoCAD 2020 without damaging the information on them. All cross referenced drawings, fonts, shapes, line types, etc. shall be included with each submittal. The A-E will be given a cover sheet to edit. The haul route and index of drawings shall be added to the cover sheet. The A-E shall provide CAD and PDF drawings on disk to the Base at each submittal, in addition to paper copies. Each sheet shall have a graphic scale. When naming drawing files begin name with the sheet number, i.e. 01, 02, 03 etc. and shall contain no special characters (% * # @ etc). The remaining characters in the filename should describe what is on that sheet. See table II-1 for use of linetype colors.

Table II-1

3. Specifications. The specifications shall be complete, clear, and shall amplify all information shown on the drawings and shall include detail requirements for materials and equipment. Material items will be specified using federal specifications or industry standards. The specifications shall be prepared using the CSI-2004 three part format Divisions 1-50.

A-E shall request the latest division one prior to start of each delivery order. The word processing file shall be in the latest version of Microsoft Word. The text font shall be Times New Roman size 11. The complete set of specifications shall be combined into one file and shall have the table of contents set up to automatically update when pages or sections are added or deleted. Paragraphs shall use the same style format as in the LRAFB division one. Provide one copy of specifications on disk as well as the required hard copies at all submittals. Pages will be numbered consecutively with page numbers centered at bottom. A minimum one inch margin on all sides is required. Section number will be indicated on the bottom center of each page in front of the page number.

4. Cost Estimates. The cost estimates shall be based on labor and material prices prevailing in the project's locality. The cost estimates shall be descriptive, detailed, and include all operations of work required including quantities and unit costs separately for labor and material. The first sheet of the cost estimate shall summarize all costs by engineering discipline. Cost estimates shall be modeled after AF Forms 3052 and shall clearly be broken out into types of work, i.e., new work, repair, maintenance, etc. All the line items shall be referenced to a particular point in the latest available Means Cost Data. Where Means Cost Data is not available for a particular line item, costs from a local distributer shall be obtained.
