3. Design Analysis

4. Interior Design

5. Documentation Requirements – Other than Drawings

6. Documentation Requirements – Drawings

1. GENERAL: This is a mandatory guide for use with contracts managed by offices of the 78th Civil Engineer Group (CEG). This Guide shall be used in conjunction with the Robins Base Facility Standards (current edition). These types especially apply:

a. Open-end IDIQ Contracts with Architect-Engineer (AE) Firms

b. Designs performed under design-build contracts

c. Any other contracted services for design or consulting services

2. SITE INVESTIGATIONS

a. General:

(1) Check exterior utility connection points to insure they match record drawings. Utilize detection equipment to verify locations of existing utilities including electromagnetic detectors and ground penetrating radar. Where utilities cross (both new and existing), particularly where gravity utilities are involved, verify depth with potholing (use air equipment). Check with 78 CES shops for their experience at your particular site.

(2) Check above drop ceilings. Lift panels to check for a drop ceiling above ("Must be removed" - Fire Department), insulation, electrical conduit, HVAC ducts, roof material, etc.

(3) Make engineering judgments about concealed utilities. For example, assume electrical seal-offs must be replaced. Include these judgments in your analysis.

b. Architectural:

(1) Carefully examine exterior protective coatings, as follows:

(a) Examine present coating and determine type of coating material.

(b) Examine subsurface for potential problems in recoating.

(c) Advise proper surface preparation.

(d) Advise good protective coating system for application.

(2) Confirm existing building interior and exterior dimensions for repair/renovation projects, particularly if Govt. record drawings have been provided. Check clearances for handicap accessibility.

(3) Review existing door and hardware condition, including door swing, types of hardware, etc.

(4) Examine for any visible signs of previous stormwater damage. Ascertain the cause of the damage and advise corrective measures.

(5) Examine for any hazardous conditions for correction. These include protrusions, trip hazards, unsafe equipment, etc.

(6) Examine for hazardous materials that may be present including, but not limited to, lead based paint, asbestos containing materials and dust contaminated with heavy metals. Normally, the SOW for the project will contain scope for identifying and testing for these materials, but the designer should record any suspect materials during the inspection regardless.

(7) Examine existing structural components for any visible damage or possible overloading conditions.

c. Civil:

(1) Check existing grades such as invert elevation at manholes, drainage ditches, and culverts.

(2) Check existing trees, shrubs, etc., for location in reference to new building or addition. Work on trees and shrubs must be approved by 78 CEG/CEIER and shall be IAW with current Antiterrorism guidelines.

(3) Check existing pavements and foundations.

(4) Check location of existing roads, parking areas, etc.

(5) Check grades required for adequate drainage.

(6) Check details for patching pavement over new utilities, etc.

(7) Check sodding and seeding requirements.

(8) Soil borings are required on new building, building additions, and paved areas (such as aircraft aprons and equipment storage areas) for both structural and environmental conditions.

(9) Ground Penetrating Radar and “potholing” is required to locate existing underground utilities.

d. Mechanical:

(1) Check heating/cooling system: Natural gas, steam, chilled water, compressed air, etc. Locate nearest tap points if not presently in use.

(2) Get nameplate data on equipment to be reused such as air-handling units, chillers, compressors, etc.

e. Electrical:

(1) Check primary power and service entrance.

(2) Get nameplate data on equipment to be reused such as panelboards, transformers, etc.

(3) AE shall obtain and provide an energized work permit to 78 CEG/CEN electrical engineer prior to opening energized electrical equipments.

(4) Open switchboards, panelboards, etc., to check for spares and spaces. Put tags on them to prevent Base shop personnel from using them when needed for this project. Use PPE as per NFPA-70E shall be required when examining switchboards, panelboards, etc.

(5) Take voltage and amperage readings on existing equipment. Use PPE as per NFPA-70E.

(6) Generally, schedule the removal abandoned conduits and conductors.

f. Fire Protection:

(1) Check fire protection system: Fire water piping, fire hydrant, making water flow tests, fire pump tests, etc. Locate nearest tap points.

3. DESIGN ANALYSIS:

(2) Conferences and Meetings:

(a) Provide the Contracting Officer and the Base Project Manager a written record of all conferences and meetings (other than formal review conferences) held between the Government and the AE during which the technical design of the project is discussed. These records cannot constitute any "Notification of Change" as described by the changes clause of the contract.

(b) Provide each record within 2 workdays after the conference or meeting.

(c) Include these in the Design Analysis.

(3) Originals: Provide disk copies of word processing documents in Microsoft Word and PDF format as part of the Corrected Final package.

The base version may include typical General Conditions that are often overlooked. Provide disk copies of the cost estimate files.

(5) If building will be occupied during construction, contractor shall identify all hazards during the design phase that may have an adverse effect on building occupants, equipment, building systems, etc.

during the construction phase. (For example: Project that includes working on roof over occupied space: cutting insulation, replacement of existing screws can cause dust particulates and other airborne particles that may be a hazard for personnel and/or equipment below.) Contractor shall provide design to contain all hazards to building occupants, equipment, building systems, etc. for contractor to utilize during the construction phase.

b. Specifications – General:

(1) Specifications shall be edited copies of the Robins Division 1 specifications maintained by 78 CEG/CENMP and Unified Facilities Guide Specifications (UFGS) found at the following link http://www.wbdg.org/ccb/browse_org.php?o=70. In additions, all specifications shall be in accordance with Robins AFB Base Facility Standards. The project manager will provide the Robins AFB Division 1 Specifications to be included in all projects. The project manager will work with the RFP A-E and Design-Build A-E to ensure that the Robins AFB Division 1 Specifications are included as part of the project.

(2) Edit out in each section any extraneous material that does not apply to the project.

(3) The design shall take into consideration that the specifications override drawings when a conflict arises between the two.

(4) When one manufacturer of an item of equipment is used as the design basis, clearly state the name, catalog numbers, etc. List all salient accessories, features and/or characteristics to be compared with other manufacturers' equipment. Do not use the clause "or equal." Ensure that items are not sole source.

If an item must be sole source (such as to match existing systems, etc.), detailed rationale must be provided in the design analysis and approved by the Base Project Manager.

c. Specifications – Quality Check Items: These are commonly found to be handled incorrectly or incompletely in many submittals and are provided to assist with the AE’s quality control methods.

(1) Date with the latest published date all referenced standards, codes, etc.

(2) Do not refer to sections that do not exist in the package.

(3) Provide with the Preliminary submittal marked up copies of the Specifications showing planned inserts and deletions.

(4) Section page numbers must be in index and on each page at the lower right, e.g. l5050-l thru l5050-5 and on lower right include - Section Name and then 15050 1-5 below.

(5) Provide project number at the beginning of each section.

(6) Do not use statements or clauses in the technical specifications that may conflict with standard FAR clauses. The following are mentioned in the AFSC/PZIO boilerplate:

(a) Methods of payments

(b) Guarantees

(c) Evaluation of bids

(d) Bidding procedures

(7) Do not use terminology that conflicts with standard Government terminology.

(a) Do not use the term "owner." Refer to Robins AFB as the "Government."

http://www.wbdg.org/ccb/browse_org.php?o=70

(b) The person in charge of the contract is the "Contracting Officer," not the AE, inspector, or architect.

(c) We only recognize the "Contractor," not any subs.

(8) Ensure specified equipment and materials are readily available, especially when renovating existing equipment.

(9) Use "shall" when describing a requirement that the Contractor must do. Use "will" when describing something the Government intends to do. (We prefer direct statements such as "Provide lights," over indirect statements such as, "The Contractor shall provide lights.")

(10) Include all forms mentioned in the body of the specification as submittals as attachments for contractors to pull off and submit.

(11) The AE may specify products by brand names. The following guidance must be followed.

(a) The Material and Workmanship Clause of the FAR included in all construction contracts, in brief, permits the contractor to use any American-made product which complies with the objectives of the Government as specified in the specifications and drawings. FAR 52.236.5(a) states . . . "The Contractor may, at its option, use any equipment material, article, or process that, in the judgment of the Contracting Officer is equal to that named in the specifications." Further, FAR 52.236-5(a) clearly states that mere reference "to equipment material, articles or potential processes by trade name, make or catalog number" establishes a standard of quality and does not limit competition. Consequently, merely stating a product without any restrictive modifiers will establish a standard. For example, "The fluorescent fixture in the specifications and drawings is a Lithonia XYZ."

(b) A problem arises when the specifications and drawings specifically limit the product to be utilized by the contractor. This undesirable end can be accomplished very simply. For example, the specifications and drawings could state, "The product shall be Lithonia," or "This product shall be manufactured by Lithonia." The word "shall" is, in the FAR, mandatory on the part of the reader. Other restrictive phrases are "Acceptable manufacturers are . . ." and "The only acceptable manufacturers are .

. .” By negative implication, no other manufacturers are acceptable.

(c) The rule of construction then to be followed is that neither the specifications nor drawings can limit the extent of competition directly or by inference. Some suggested and acceptable phrases are these:

"The design basis is . . .", "Some acceptable manufacturers are" or "Acceptable manufacturers include . .

....” Do not include both a design basis and acceptable manufacturers.

(d) Since a design basis establishes quality only, we need to specify those features and accessories that would make a product "equal." We have had problems in the past in failing to specify and obtain all accessories even when the design basis is used, so make sure they are called out for.

(i) Typical wall, roof, and partition sections generally at no less than 3/4" = 1'-0" scale to include material and thickness of facing and method of attachment, type of doors and other openings in supporting structural walls.

(j) All required controlling dimensions shall be clearly indicated.

(k) Identify sections or details by numbers within a circle which include consecutive detail numbers, the sheet on which the detail is referenced, and the sheet on which the section or detail is drawn. Include an example in the legend.

(l) Drawings shall contain sufficient detail to clearly indicate type and sizes of materials, utilities, etc., and specifically list separately all contractor-furnished equipment and all Government- Furnished equipment to be installed by the contractor.

(m) Structural Steel Connections: The design of all structural steel connections shall comply with the latest edition of the American Institute of Steel Construction Specifications. Design of structural connections is the responsibility of the AE. Details shall show the size of connecting members, size and length of welds, and number and size of bolts. Specifications shall cover all required materials, processes, and procedures. Minor details of dimensioning, etc., related to code compliance may be left to the fabricator. The Government will review shop drawings for conformity with the design, unless shop drawing review is contracted to the AE separately.

(4) Final Drawings: The AE shall not proceed with the final drawings until receipt of written review comments and/or approval of Phase I and II requirements from the Office of the Civil Engineer. Written review comments shall be annotated by the AE and submitted along with the next submission of documents. The first submission of final documents shall be a complete design needing only a few minor corrections or changes.

(5) Marking and Certification:

(a) Drawings in each submission are to be dated as appropriate and stamped as "Preliminary," "First Finals", or "Corrected Finals".

(b) The AE, or his authorized representative, shall sign the original drawings and the first page of all specifications, estimates, or similar documents under the AE contractor's printed name and over the affixed replica of his professional seal (or his registration certificate number and including the State of Georgia issuance).

(c) AE's name and address shall be printed on each sheet.

(6) Because the government will convert most drawings to a format suitable for electronic advertisement, raster images that are used to create drawings must be handled in a special manner. They must be attached as raster reference files rather than being imported directly into the design file.

c. Drawings - Quality Check Items: These are commonly found to be handled incorrectly or incompletely in many submittals and are provided to assist with the AE’s quality control methods.

(1) The types of information required on each submittal are clearly stated in the Statement of Work. Follow closely, or you may be required to resubmit.

(2) Title sheet must have a drawing index.

(3) Provide a key plan for each sheet where a part plan is shown.

(4) Provide separate demolition and installation plans for all work, unless specifically waived by our project manager. Use l" = l00' on utilities if enough detail can be shown. Include topography if applicable.

(5) Use as large a drawing scale as practical. Use at least l/8" = l'-0" on layout plans, building elevations and building sections, and 3/4" = l'-0" on wall sections and 1-1/2”=1’-0”on details.

These drawings may be reduced to half-size in the future. Where multiple floor plans of the same level are required, use key plans and match lines on each plan sheet.

(6) Do not show too much on each floor plan. For example, showing ductwork, chilled water lines, hot water lines, and steam lines on the same floor plan results in confusion. It is necessary to use separate floor plans for each system.

(7) All originals (drawings) shall be stamped with the Architect/Engineer seal prior to Corrected Final submission and have AE name and address.

(8) The use of schedules for all energy consuming or distribution equipment is required. Provide all pertinent characteristics of the utility involved, e.g., voltage, phase, and power for electrical equipment. Fans and other mechanical equipment using motors shall have electrical characteristics specified by the electrical engineer and scheduled on electrical drawings, regardless of who supplies them. Specify who provides (Div. l5 or l6).

(9) Provide a reflected ceiling plan on Architectural Drawing which coordinates all electrical and mechanical systems.

(10) Provide controls, schematics, and ladder diagrams for mechanical systems.

(11) On new construction, show on the drawings the design structural loads and the strength of all structural materials used in the project.

(12) Provide scale and title for each detail and part plan.

(13) Notes: indicate whether "General," "This Sheet Only," "This Detail Only," etc.

(14) Do not crowd work. Use extra sheets and allow for additional details, sections, notes, etc.

Although the preliminary submittal will not have all the details shown, please indicate where and what you intend to section or detail. This may be a list included as part of the design analysis.

(15) Project title appears in title block of each sheet. Then, in smaller letters, title for the individual sheet. Describe sheet as clearly as possible: e.g. instead of "New Work" use "Electrical New Work, Second Floor, East Wing".

(16) Date all referenced standards, codes, etc.

(17) HVAC and Electrical work must comply with Base Facility Standards.

(18) Plans and details should be oriented so that "North" is toward the top or left side (nine o’clock position) of the sheet, whichever is most practical. Each detail and the key plan shall have a north arrow.

(19) Use size "ANSI D" drawings instead of "E", unless totally impractical. Notify Project Manager when “D” size drawings are totally impractical.

(20) Notes on Drawings - Need them. It is not sufficient to put in an insulation spec on what and how to insulate and then not tell them to do it (either in spec or on drawings, whichever is clearer).

(21) Photo drafting is often helpful in demolition and renovation.

(22) Use separate floor plans for lighting, power, lightning protection, telephone, security, and fire safety.

(23) Provide one-line diagrams for power, fire safety, security, and telephone.

(24) List nameplate data on reused existing equipment.

(25) Final Drawings. These drawings should be in a 100% complete design that is ready to "put on the street." All review comments should be incorporated. Complete all schedules, plans, etc., for each discipline. Provide additional notes on the drawings to insure quality construction.
