STANDARD ENGINEERING GUIDELINES

USING THE STANDARD LABORATORY LAYOUTS

In an effort to provide guidance to those requiring renovations of the NIEHS David P.

Rall Building (Building 101) laboratories, and to allow the ORF to respond to laboratory renovation requests in a timelier manner, we have developed a set of "Standard Laboratory Layouts." These layouts will allow FMB-NC engineering personnel, with the DIR Facility Coordinator, to work with those requesting laboratory renovations the flexibility of choosing from a variety of layouts by mixing and matching from a selection of wall elevations which detail such items as casework and laboratory hood arrangements. The ability to choose from pre-designed plans will offer Requestors an opportunity to tailor their laboratories to their specific research needs, while also allowing FMB-NC to more quickly respond to renovation requests. After selection by the Requestor, these layouts can then be utilized by FMB-NC to expedite the laboratory renovation by reducing the need for custom designs. Although custom designs and non-stock casework types will still be available, the time needed to accomplish these requests will be greater than that for the "Standard Laboratory Layouts."

All laboratories within Building 101 are designed around a typical 10’× 20’ (200 ft2) module laboratory. The laboratory wall partitions are demountable, allowing them to be removed to create a double (20’ × 20’), triple (30’ × 20’), or quad (40’ x 20’) module laboratory. Though this type of standard laboratory module offers flexibility in the arrangement of laboratory sizes, certain limitations still remain due to the design and construction of the building and its utility systems. For example, a laboratory hood usually can be installed on either wall perpendicular to the corridor, but the location of the hood on the wall is fixed due to the need to duct it from the laboratory through the penetration in the ceiling. For further guidelines on the Building 101 laboratories and their restrictions, see the “GUIDELINES FOR STANDARD LABORATORY LAYOUTS” on page 14.

The step-by-step process for utilizing the “Standard Laboratory Layouts” is as follows:

1. Select from the single (10’ × 20’), double (20’ × 20’), triple (30’ × 20’), or quad (40’ x 20’) laboratory module plan, as appropriate.

2. For each location of casework, laboratory hoods, and biological safety cabinets, choose from the wall or peninsula elevations provided. Mark the desired elevation(s) on the laboratory module plan (single, double, triple or quad) in the appropriate location(s). Again, see the “GUIDELINES FOR STANDARD LABORATORY LAYOUTS” for more information on the Building 101 laboratories.

3. Choose from casework shown in Figure 16: Standard Stock Casework Examples on page 32 to fill the available space for each elevation. Mark the casework numbers on the wall and peninsula elevations in the appropriate locations.

NOTE: Each piece of casework is available in either high (36”) or low (30”) bench; the stock numbers indicate the height.

To demonstrate how to use these layouts, we have included an example that will take you through the process of selecting the arrangement for a double laboratory using the “Standard Laboratory Layouts.”

Finally, the following plans and elevations represent the first of the standard designs to be offered. We have developed the standards offering the most commonly requested elevations, though these will be updated as other layouts are required, as determined by either a consistent request for a different specific arrangement or changes in the needs of the researchers. We strongly encourage your use of these standard layouts to not only provide you with guidance in the features of the Building 101 laboratories, but to also permit us to respond to your requests in a timely manner.

Please let us know if you have any questions.

STANDARD LABORATORY EXAMPLE

This example demonstrates the use of the “Standard Laboratory Layouts” in arranging the renovation of a double laboratory module for a standard Requestor. The following is the step-by-step process used in arranging the layout.

1. Working with the FMB-NC Contracting Officer’s Representative (COR) and DIR Facility Coordinator select from the single (10’× 20’), double (20’ × 20’), triple (30’ × 20’), or quad (40’ x 20’) laboratory module plan, as appropriate.

Because the renovation is for a double (20’ × 20’) laboratory, G542/544, the “Double Laboratory Module Plan” is chosen.

2. For each location of casework, laboratory hoods, and biological safety cabinets, choose from the wall or peninsula elevations provided. Mark the desired elevation(s) on the laboratory module plan (single, double or triple) in the appropriate location(s).

NOTE: The elevations are shown as if they are used on the left wall (left elevation) of the laboratory and the right side (left elevation) of a peninsula, as seen when facing the window (or interior) laboratory wall. Each of the elevations can be utilized by mirroring to the right wall or left side of the peninsula.

For the left wall (as you enter the laboratory from the corridor) elevation, Dr. Doe has chosen Elevation E; for the right wall elevation, she has chosen a mirror image of Elevation H; and Elevation F and a mirror image of Elevation F for the right and left side of the peninsulas, respectively.

3. Choose from casework shown on the pages entitled "Stock Casework" to fill the available space for each elevation. Mark the casework numbers on the wall and peninsula elevations in the appropriate locations.

NOTE: Each piece of casework is available in either high (36”) or low (30”) bench; the stock numbers indicate the height.

Dr. Doe has provided the numbers for the casework she has chosen for each location on the elevations. Note that the stock numbers provided indicate that she wants high (36”) bench casework installed on most of the left wall, except for the 30” wide low (30”) knee space and the adjacent low bench drawer unit. The casework on the right wall is all indicated to be high bench and is 9’ (36’’ + 36’’ + 36’’) long, while all 12’ of the peninsula casework is indicated to be high bench.

4. The FMB-NC COR will prepare subsequent contracting packages using the laboratory casework and laboratory hoods selected by Dr. Doe and work with the DIR Facility Coordinator to prepare a milestone project schedule.

FREQUENTLY ASKED QUESTIONS (AND ANSWERS) ABOUT BUILDING 101

LABORATORIES

The following are questions and answers regarding the laboratory spaces in Building 101, and the use of the “Standard Laboratory Layouts.”

Q1. Are sinks only allowed on peninsulas?

A1. No. Sinks are permitted anyplace in the casework, whether that is on a peninsula or along a wall, with the exception of behind door swings. Sinks located behind door swings make it likely that a person working at the sink would be struck as others enter the room.

Q2. Can casework be installed along only part of the wall to allow room for desks or equipment?

A2. Yes. For example, Elevation H of the Standard Laboratory Layouts would allow for any length of casework (e.g. 10’) up to the length of the wall (20’).

Q3. The Guidelines state that only one emergency circuit is permitted per laboratory module. How many outlets are permitted?

A3. One 20 amp emergency circuit (with two duplex receptacles, two outlets per receptacle or four outlets total) can be installed in a single module (10’ × 20’) laboratory, two 20 amp emergency circuits (with two duplex receptacles, two outlets per receptacle or four outlets total) can be installed in a double module (20’-0” × 20’-0”) laboratory, etc.

Q4. Can a 36” wide knee space drawer unit be selected instead of the 30” unit (501S222) shown as stock?

A4. The 30" knee space drawer unit is readily available in the NIEHS warehouse stock; however the 36" wide unit is not. A 36" wide unit (like most other “non-stock casework”) can be specially ordered, but purchase and delivery will delay completion of the work. If enough demand for a specific unit other than that now shown as “stock” occurs, we will consider adding that piece to the line of “stock casework”. The knee space drawer units are available from the supplier in lengths from 24” to 72” in 6” increments.

Q5. Can anything be done to increase the utility of the space along the corridor wall between the doors in a double or triple laboratory?

A5. This space is commonly used for equipment such as refrigerators or freezers, and though not shown on the Standard Laboratory Layouts; electrical power (including the one emergency receptacle permitted per module) can be installed at this location upon request.

Q6. Can open spaces (not knee spaces with or without drawers) be provided under countertops for small refrigerators, incubators, etc.?

A6. Yes. Space can be provided beneath countertops, though obviously the length would be limited to that which could be safely spanned with the counter. This should be noted on the elevations by showing “no casework” or similar notation.

Q7. Can casework be omitted on either side of the BSCs shown on Elevations C and

D?

A7. Yes.

Q8. Peninsula Elevation F needs electrical receptacles at the ends because these are the logical places for equipment. Also, how many receptacles are to be standardly provided on any Elevation?

A8. Requestors should show electrical receptacle locations on the “Standard Laboratory Layouts” if specific locations are required. The elevations indicate duplex receptacles on normal power (not including the emergency duplex receptacle), which is approximately double what has been provided in the past.

This provides the ability to plug in 18 different pieces of equipment along each wall. The Requestor should bear in mind that each single laboratory module (10’-0” × 20’-0”) is still supplied with the same 60 amp electrical service, which should be more than adequate for a reasonable number of pieces of equipment, especially today’s low-power digital equipment.

Q9. Even though it may not be shown, is shelving available on all of the standard wall elevations?

A9. Yes.

Q10. Is piping available to accommodate de-ionized water units?

A10. It is now standard that valved and capped stubs are provided at each sink location for future installation of package de-ionizing units.

Q11. Must the emergency receptacle be installed in the laboratory wireway terminal box?

A11. No. The emergency receptacle can be installed at another location upon request, but its location is restricted by the building’s physical limitations.

Q12. Can sliding (pocket) doors be used instead of standard doors?

A12. No. Pocket doors pose a safety hazard (e.g., in the event of emergency egress in the event of a fire) and are not suitable for installation in a laboratory environment.

Q13. Can the gas, air and vacuum outlets be installed in the walls instead of on the benchtops?

A13. No. The laboratory services (i.e., plumbing, electrical, and data/communications) enter the laboratories through sleeves in the poured concrete floor which are centered a few inches out from the walls. Since they would then have to rise vertically through the countertop to get to wall outlets, this would negate the benefit of having them on the wall.

Q14. Can the phone jacks be at the end of the benchtops?

A14. Yes. The phone jacks will be located along the walls at the location desired by the Requestor.

Q15. Must two hoods be installed in a double laboratory?

A15. No, laboratory hoods are not required to be installed in laboratories. However, there is a maximum of one 4’ laboratory hood per single (10’ × 20’) laboratory module. 6’ laboratory hoods can be installed in double, triple, or quad modules.

Q16. Can two emergency receptacles be installed in a single laboratory module?

A16. Yes. An emergency duplex receptacle can be installed in each wireway junction box, but both will be installed on the same 120V, 20 amp circuit. The circuit size is limited to one 20 amp circuit per single laboratory module due to the capacity of our emergency generators.

Q17. Can knee spaces be installed in peninsulas in double and triple laboratories?

Not enough knee spaces are available; there needs to be at least two in a double laboratory, three in a triple laboratory, and they shouldn’t be next to hoods.

A17. Knee space locations can be installed in peninsulas or elsewhere, at locations and in the quantity requested by the customer.

Q18. Can shelves be placed high on the walls? Are wall cabinets (with doors) available?

A18. There is a limit to wall and reagent shelving height due to safety considerations.

Shelving height should not exceed 6’ above the finished floor. Wall cabinets are available.

Q19. Do the restrictions on shelving and casework adjacent to exterior walls apply to the ground floor?

A19. The windows on the first floor are high enough that the requirements for shelving to be 24” from the wall can be ignored.

Q20. Are multi-outlet blocks with surge suppressors permitted for computers or other equipment requiring conditioned power?

A20. Multi-outlet strips with surge suppressors may be used for low-power equipment such as computers provided they have circuit protection and are used with discretion. Extension cords, drop cords, and zip cords are not permitted. All multi-outlet strips that are allowed must be UL approved. Additionally, there cannot be any “daisy chaining” of the multi-outlet strips (i.e. plugging one strip into another one to gain extra receptacles). Clearance on multi-outlet strips should be obtained from the Facilities Management Branch/ORF/NIH and the Health and Safety Branch/NIEHS.

Q21. Are space heaters allowed in laboratories?

A21. No, NIH and NIEHS policies do not permit the use of space heaters in laboratories.

GUIDELINES FOR STANDARD LABORATORY LAYOUTS

ARCHITECTURAL

• Laboratory modules can only be divided in spaces which are whole multiples of 10’; e.g., 10’× 10’, 10’ × 20’, etc.

• Fixed equipment, shelves, or wall cabinets shall not be installed on the walls at window height within 24” of the windows.

• Countertops consist of 1” medium-density fibreboard (MDF) covered with a heat and chemical resistant Formica laminate. Solid surface epoxy resin countertops are sometimes used in special situations. Countertops come standard 5’-0” wide but as an option can be made 6’-0” wide.

• No desks or knee-hole openings in laboratory casework behind door swings.

• No desk or computer work stations will be situated directly opposite or beside a laboratory hood or biological safety cabinet.

• Maximum of one change in casework height [i.e., 30” to 36”] per wall elevation.

• All reagent shelves shall be limited to a height of 6’ above the floor. Reagent shelving comes standard 24” wide and must have 2’-0” of clearance at the window.

• Laboratory casework, electrical power, or utilities shall not be installed along exterior window walls.

• Holes shall not be drilled into removable wall panels.

• Equipment shall not block operation of corridor doors, except that in triple module

(30’ × 20’) or larger laboratories the center door may be blocked with noncombustible equipment (e.g., refrigerator). Please consult with the Health & Safety Branch for guidance and approval.

• Sinks shall not be located behind corridor door swings.

• Cup sinks are not the preferred option for on the laboratory bench top or within the laboratory hood or biological safety cabinet.

• Offices with an entrance to a laboratory area should not have carpet flooring. Any spill within the laboratory could easily be tracked into the office and contaminate the carpet.

ELECTRICAL

• Each laboratory has an electrical and communications wireway junction box located above the laboratory casework. This junction box feeds surface mounted raceway systems. Each laboratory is fed by a 60-amp 3-pole, 208Y/120 VAC circuit. Individual 208V and 120V receptacle circuits are fed by circuit breakers located in the laboratory raceway. Electrical power with 120 V duplex receptacles is fed through a raceway (the upper raceway in Modules C, D and E) with local circuit breaker protection; 208 V single or three phase service can be provided.

The number of receptacles is limited by the expected load. In Modules C, D and E there is a lower raceway for telephone/data communications wiring, while in Module F the telephone/data jacks are located in the wireway junction box.

• Any electrical receptacle within six feet of a sink must be protected by a ground fault circuit interrupter (GFCI).

• Electrical conduit should continue behind fume hoods.

• No more than one 120 V, 20 amp emergency circuit can be provided in each laboratory for emergency power. Emergency duplex receptacles are installed in the laboratory wireway junction box and other locations as requested.

• Multi-outlet electrical extensions are not permitted. Multi-outlet strips with surge suppressors may be used for low-power equipment such as computers provided they have circuit protection and are used with discretion. Extension cords, drop cords, and zip cords are not permitted.

• Laboratory units with peninsula casework shall have a raceway with 120 V duplex receptacles under the bottom reagent shelf facing both sides.

• No electrical power or outlets shall be installed along exterior window walls.

• There are a limited number of back-ups that are feasible for any electrical system. The Building 101 emergency power system is designed for the worst of catastrophic interruptions. The system provides the emergency lighting to allow personnel to safely exit the building. It also provides power to maintain necessary animal facility services and critical laboratory equipment (e.g. refrigerators, freezers, incubators, etc.).

• Each 10’ x 20’ module should be equipped with Metasys equipment monitoring conduit and wiring to facilitate scientific equipment monitoring.

MECHANICAL

• FMB-NC does not provide deionized or distilled water to laboratories. These services are provided by DIR. Please contact the DIR Facility Coordinator.

• Plumbing services are from the interstitial space below, with fixed floor penetrations located as shown in Figure 15: Penetration Locations for Standard Utilities on page 31.

• A typical laboratory module is 10’ x 20’, and operates under negative pressurization relative to the corridor (i.e., air flows in from the corridor). Offices have a neutral air flow rate. The typical laboratory module has the following average air flow rates:

Without Laboratory Hood (Module C, D, E) Exhaust 450 cfm Supply 350 cfm Corridor 100 cfm

Without Laboratory Hood (Module F) Exhaust 625 cfm Supply 525 cfm Corridor 100 cfm

With Face Bypass Laboratory Hood Exhaust (6 ft. hood) 610 cfm* Supply (6 ft. hood) 510 cfm Exhaust (4 ft. hood) 375 cfm* (hood) + 75 cfm (room) Supply (4 ft. hood) 350 cfm Corridor 100 cfm

*Note: As of May 2012, 610 cfm replaces the old 690 cfm for the exhaust of a 6 ft. hood and 375 cfm replaces the old 420 cfm for the exhaust of a 4 ft. hood as the manufacturer, Fisher Hamilton, has changed their standards for this type of hood.

• Biological Safety Cabinets (BSC’s), Class II, Type B1 (30% air re-circulated; 70% exhausted from cabinet) have the following established guidelines:

o 4’-0” BSC with an exhaust requirement of 282 cfm can be installed in a single laboratory unit with no additional equipment requiring exhaust.

o 6’-0” BSC with an exhaust requirement of 474 cfm must be installed in a minimum double laboratory unit. Allowance of additional equipment requiring exhaust is dependent on its exhaust requirement.

• Biological Safety Cabinets (BSC’s), Class II, Type B2 (total exhaust) have the following established guidelines:

o 4’-0” BSC with an exhaust requirement of 785 cfm must be installed in a minimum double laboratory unit with no additional equipment requiring exhaust.

o 6’-0” BSC with an exhaust requirement of 1250 cfm must be installed in a minimum triple laboratory unit with no additional equipment requiring exhaust.

• BSCs have the following established placement guidelines:

o At least 40” of undisturbed space must be maintained around the BSC.

o At least 12” of distance from BSC to adjacent walls or columns must be maintained.

o At least 80” of distance from BSC to opposing walls must be maintained.

o At least 60” of distance from BSC to opposing bench tops or occasional traffic areas must be maintained.

o At least 40” of distance between BSC and bench top along perpendicular wall must be maintained.

o At least 120” of distance between opposing BSCs must be maintained.

o At least 40” of distance between BSCs along the same wall must be maintained.

o At least 48” of distance between BSCs along perpendicular walls must be maintained.

o Placing BSCs near entryways is not recommended. If absolutely necessary maintain a distance of 40” to adjacent doorways and 60” to doorways behind the workspace.

o No desk or computer work stations will be situated directly opposite or beside a BSC.

• Laboratory hoods and BSCs which require duct connections need to be located below the "knock-out" ceiling penetration such that the centerline of the exhaust outlet is directly beneath the centerline of the ceiling "knock-outs." The centerline of the "knock-outs" are approximately 6’-6” from the back wall or window.

NIH STANDARD DRAWING GUIDELINES

DRAWING GUIDELINES

1. General. Construction drawings shall convey to contractor, manufacturer, or fabricator the information necessary for accomplishing the required work. It is essential that the drawings be accurate and explicit. All elements of work shall be properly coordinated to ensure that there are no conflicts between disciplines on drawings or in specifications. They are also used to avoid duplication of information on the drawings and in the specifications.

a. The information shown on the drawings must be sufficient for satisfactory completion of the project.

b. Permanent survey control points, showing station grid coordinates, shall be shown on the drawings for all new construction on NIEHS property.

c. When applicable, complete finish, door and fixture schedules shall be included on the drawings.

d. Do not combine disciplines on drawings. There shall be only one discipline on one sheet, except on very small jobs.

e. Design drawings shall be sealed.

f. The contractor shall comply with the latest issues of all construction codes, ordinances, and standards (Federal, state, local, etc.) which govern and have jurisdiction. If conflicts occur in the requirements established by these publications, the most stringent shall govern. The current jurisdictional status of NIEHS government-owned or leased facilities is “proprietorial”, not exclusive. All federal, state, and local requirements apply. The contractor shall, without additional expense to the Government, be responsible for obtaining any necessary approvals of plans and specifications from state, county, and city authorities (such as fire marshal, building inspectors, etc.) in connection with the development of construction permits and licenses.

2. Order of Drawings. The main purpose of the recommended sequence for the drawing sheets is to provide a simple logical guide for assembling graphic components. This system is designed to be flexible to compensate for differences in both project complexity and size. The sequence of the sheets is to align with the order of construction and go from a general to detailed level of design description.

3. Hardcopy sheet order. The hard copy drawing sheets for a project should follow the organization shown below. Depending on the size and scope of a drawing set, drawing sets may be numbered and bound in a single set or by subsets. All subsets may not apply or more detailed groupings may be required depending on the scope, size and complexity of the project.

Drawings shall be arranged in the following order:

a. Title sheet and index of drawings.

b. Civil (C) (plot and/or vicinity plans and utility plans).

c. Landscape (L).

d. Architectural (A) (including interior design).

e. Structural (S) (including foundation plan).

f. Fire Protection (F).

g. Plumbing (P).

h. Mechanical (M) (such as heating, ventilation, and air-conditioning).

i. Electrical (E).

4. Drawing File Names. Drawing files shall be named by the following eight character conventions. First two characters shall be the last two digits of the year in which the project is created, the second two digits shall be the project number assigned by the NIH CAD Manager, the next character shall be the discipline (i.e. A-Architectural, E-Electrical, C-Civil, P-Plumbing, M-Mechanical), and the last three characters shall be the sheet number.

Year Project No. Discipline Sheet No.

2 Characters 2 Characters 1 Character 3 Characters

EXAMPLE:

12 XX M 001

2012, PROJECT # (TO BE ASSIGNED BY NIEHS CAD MANAGER), MECHANICAL, SHEET 1

5. Scale. All site plans, plot plans, floor plans, contour maps and other drawings of this type should be drawn full scale. Actual drawing scale will be determined at plot and by the initial drawing setup. Use standard engineering/architectural scales in all cases. The exception to this rule is vicinity maps. Vicinity maps should be scaled to fit into a 6” wide by 5” high block. Vicinity maps may be available from NIEHS and plot plans should be plotted at the largest engineering scale possible to fit on the desired sheet. Floor plans, architectural, structural, mechanical, and electrical drawings should be plotted at 1/8”=1’-0” to 1/4”=1’-0” scale where possible. Plans for each facility should be plotted on a single sheet.

Elevations should be plotted at 1/16”=1’-0” to 3/4”=1’-0” scale. Details should be plotted in the nearest practical architectural scale.

6. Text Height Defaults. Text height defaults are based on scale. Table 5: Text Height: Decimal, Table 6: Text Height: English, Table 7: Text Height: Arch. Scale indicate the default text height for each scale available for each of the disciplines.

These values also represent NIEHS’s text height requirements for notes, dimension text, etc.

7. Format. In addition to the signed PDF files; electronic files should be directly readable by the AutoCAD 2008 without conversion. Before a file is placed on the delivery media the following steps should be performed:

a. Remove all extraneous graphics and drawing entities existing outside the drawing border.

b. Zoom the drawing to the extents of the drawing area.

c. Ensure that no external reference files (X-Refs) are referenced in the drawing.

d. Ensure that the only font type used in the drawing is ARIAL.SHX.

e. Ensure that the drawing can be plotted using the extents plot routine without the need for additional manipulation. This includes maintaining the layer state used in all submitted plots. Consequently, there should a separate drawing file for every plotted sheet submitted for the project.

f. Include any standard sheets (i.e., abbreviation sheets, standard symbol sheets, etc.) necessary for a complete project.

g. Ensure that the file names comply with the eight-character file naming requirements outlined in this manual.

h. Disks may contain compressed or “zipped” files only if they are self-extracting in nature. Otherwise, only AutoCAD 2008 drawings in *.dwg format will be accepted. Similarly, a single file cannot be spanned across multiple disks unless it is self-extracting.

8. Delivery Media. The preferred type of delivery media for data exchange depends both on the hardware/software platforms utilized in creating a drawing/data file and the size of the file. Generally, digital data sets larger than 9 megabytes (MB) should be furnished via compact disk-read only memory or flash drive. CD-ROM is the preferred format due to its extended shelf life.

9. External Label. When exchanging digital media, an external label should contain, at a minimum, the following information:

a. Format and version (e.g., Microsoft Windows XP) of the operating system on which the media was created.

b. The utility or command used to write the files to the disk (e.g. file manager).

c. The sequence number in the following format:

Disk N of T where N = disk sequence number and T= the total number of disks.

d. The project description, task order, and Contracting Officer’s Representative.

10. Transmittal Sheet. A transmittal sheet should accompany the media containing, at a minimum, the following information:

a. The same information included on the external label of each CD and the file names and descriptions for each file.

b. The instructions for restoring/transferring the files from the media.

c. Certification that the delivery media is free of known computer viruses, including the name(s) and release date(s) of the virus scanning software used to check the media.

11. Drawing Sizes. Full drawing sheet size is 24” x 36”, unless otherwise specified by the Contracting Officer’s Representative (COR). Where a larger sheet size is desirable, 30” x 42” is available, but approval must be obtained from the COR.

Typical A/E projects (contract documents) will be prepared on 24” x 36” size sheets, with 11” x 17” available for half size drawings and 8½” x 11” allowable with COR permission. One full-size reproducible vellum hard copy should be provided for each finished drawing unless otherwise specified.

12. Project Title. Use the project title provided by the COR. If none is provided, use a short, concise title, which includes the building…
