1.0 SCOPE OF SPECIFICATION 1.1 Introduction 1.1.1 This specification sets out the minimum requirements and recommended practice for the architectural, civil

and structural design of free standing laboratories located in non-classified areas of oilfields and refineries. It is not a definitive, technical, contract specification, but it is intended to serve as a briefing document for

the Owner and Vendor/Contractor and to set the standards for building function, construction and ease of maintenance. Its scope is limited to functional, planning and construction criteria.

1.1.2 The intent of the document is: - To provide Owners and Vendor/Contractors with clear design guidelines for the building

envelope, components and finishes and to ensure that these are co-ordinated with functional needs of structural/civil engineering, mechanical (air-conditioning, water services and drainage) and electrical services.

- To standardise design, by providing comprehensive recommendations and requirements within a

single document. - To set benchmark standards for both building function and construction and to provide the

framework for cost-control to be implemented. - To give guidance which takes into account the climatic conditions and general methods of

construction prevailing in the region and which allows the use of construction technology requiring the minimum importation of overseas building materials and components.

1.1.3 This document is intended to serve as a design tool for Owners and Vendor/Contractors for the

administration of the building design process during pre-contract stages. It is not a definitive, project specification. Vendor/Contractors are in no way relieved from their responsibilities for the production of completed documentation and safe, functional design.

1.1.4 The Vendor/Contractor shall fully comply with the provisions laid down in the specification. Any

exception shall be authorised in writing by the Owner. 1.1.5 In the event of any conflict between this specification and any applicable codes and standards, the Vendor

shall inform the Owner in writing and receive written clarification before proceeding with the work. 1.1.6 This General Engineering Specification shall form part of the Purchase Order/Contract. 1.2 Other NOC Specifications In designing laboratories, the following additional NOC Specifications shall apply: 1.2.1 General GES A.01 - Plant Layout and Spacing GES A.04 - Noise Level Criteria and Noise Control of Mechanical Equipment GES A.06 - Site Data 1.2.2 Building GES B.12 - Heating, Ventilation and Air-conditioning

petrochemical laboratories. Accommodation and fit-out will vary in accordance with the Owner's specific requirements, but will consist of core laboratory working areas and stores, with support accommodation consisting of office space, toilets, cleaner's store and tea-room. Laboratory storage for acids, solvents, reference fuels and samples should be kept to the minimum required for operations. All flammable liquids must be labelled properly and stored in specially designated places.

3.2.2 Schedule of Accommodation The following areas are indicative only and will vary from site to site in accordance with the Owner's

specific requirements: (a) Oilfield Laboratory Laboratory working area - 32sq. metres Offices - 12sq. metres General/Equipment Store - 6sq. metres Tea-room - 6sq. metres Cleaner's Store and Toilet - 8sq. metres Corridor - 11sq. metres Gas Bottle Store - external Hazardous Materials/Waste Store - external


GES B.11 of 26 Rev 0 1999

(b) Refinery Laboratory Laboratory - 84sq. metres Offices - 12sq. metres Laboratory Storage - 9sq. metres Cleaner's/Domestic Store - 8sq. metres Toilets - 12sq. metres Gas Bottle Store - external Waste Store - external HVAC - 60sq. metres Laboratory Workshop - 80sq. metres Maintenance Workshop - 8sq. metre (c) Petrochemical Laboratory Laboratory - 230sq. metres Offices - 50sq. metres Laboratory Storage - 50sq. metres Cleaner's/Domestic Storage - 8sq. metres Toilets - 25sq. metres Gas Bottle Store - external Waste Store - external HVAC - 100sq. metres Laboratory Workshop - 200sq. metres Maintenance Workshop - 30sq. metres 3.2.3 Sound Attenuation It is essential that noise should be kept to a minimum between the rooms of the building and that staff

should be undisturbed by normal external noise. Sound insulation and attenuation performance of external walls and windows therefore shall be no less than 31 Db. In particular, the following standards shall apply:

BS 2750: Part 3: Measurement of the Insulation of Buildings and of Building elements. ASTM E 336: Method of Measurement of Air-borne Sound Insulation in Buildings. 3.2.4 Housekeeping A particularly important aspect of laboratory design concerns the ease with which routine work can be

carried out, while minimising hazards: (a) Provision shall be made for the safe handling and storage of laboratory reagents and solvents

giving due regard to their toxic and reactive natures and quantities involved. These quantities shall be the minimum necessary for operational use and kept in separate, fire-resistant stores within the laboratory working area.

(b) Where refrigerants such as dry ice or liquid nitrogen are used in the laboratory, care is needed to

avoid cold burns, asphyxiation and related hazards. (c) Prompt and correct disposal of waste materials helps to reduce fire and environmental hazards and

the necessary exposure of personnel to disagreeable odours and toxic vapours. (d) Care shall be taken in the location and use of electrical apparatus not designed for hazardous

atmospheres. In particular, domestic refrigerators shall not be used for the storage of solvents and flammable liquids.


GES B.11 of 26 Rev 0 1999

3.3 Testing and Analysis Routines The design of laboratories shall be based on well defined test requirements for the routine standard tests

carried out in oil fields, refineries and petrochemical plants. The exact lab space requirements shall be developed only after all the required instruments to carry out

these tests have been specified. The eventual need for additional space for any future requirements shall be examined at the preliminary

stage. While laboratory activities for oil fields require simple tests using conventional benching, storage cupboards and sinks, the test requirements for Refinery and Petrochemical labs are very complex requiring a wide range of analytical and physical testing processes and procedures, thus the lab space is bigger especially for the Petrochemical Labs where the need also for a plastics workshop for extrusion and other machines requires a lot of space. Laboratory designers, should take into consideration the fact that the performed tests involve the use of volatile, corrosive, toxic and flammable substances, thus provisions shall be made in the design to minimise any potential hazard to personnel and the environment.

Whenever possible very hazardous tests shall be performed in segregated areas from the remaining

Laboratory space. The required tests for the following types of laboratories may include, but not be confined to the following as listed:-

3.3.1 Oilfields . Basic, Sediment and Water (BS&W) (Bottom Sediment and Water) . Specific Gravity . Viscosity . Water Analysis for Mg, Na, Cl, S04, S02 . Mass Chromatography . Flashpoint . RVP . Pour Point 3.3.2 Refineries . Tetraethyl Lead Test (TEL) . Basic, Sediment and Water . Sulphur . Hydrogen Sulphide . Copper Strip . pH . Viscosity . RVP (vapour pressure) . Density . Distillation . Water Content . Pour Point . Cloud Point . Wax Point . Mass Chromatography . Titration . Acidity . Water Treatment Tests 3.3.3 Petrochemicals . Composition Analysis by Gas Chromatography . Composition Analysis by Mass Spectography


GES B.11 of 26 Rev 0 1999

. Distillation . Density . Extrusion . Film Forming Tests will vary from site to site in accordance with the Owner's specific requirements. 4.0 CIVILS 4.1 Groundworks Refer to GES A.06 for requirements regarding basic background information on site conditions. 4.1.1 Site Investigation Reports The extent and type of groundworks and foundation design will vary from site to site and will be dependent

amongst other factors, on the overall structural design of the building. In all cases, a site investigation report shall be prepared for the Owner's approval before detailed design development is embarked upon. A site investigation should demonstrate the suitability of the proposed site for the construction of civil engineering and building works. It shall examine all parameters which may influence the design of the building and the security of neighbouring land and property. All site investigation reports shall include an appraisal of the following:

(a) Site access (b) Levels (c) Drainage and Sewage (d) Ground bearing capacity (e) The presence of buried services (f) Adjacent buildings (g) Overhead power lines and other features Foundation design shall conform to the guidelines set out in GES Q.03. Particular care shall be taken to

ascertain the degree of sulphates and other aggressive salts in the ground. As a general rule, allowance shall be made for sulphate resisting cement to be used in all below ground construction.

4.1.2 General Ground floor levels shall be raised to minimum 450mm above the general external ground to reduce the

entry into the building of wind-borne sand and dust and to protect the building during heavy storms which are liable to cause local or flash flooding. Local surface conditions shall be investigated to ensure an adequate run-off of water during the brief but intense periods of rainfall.

4.2 Load Bearing Material Structural load bearing materials shall be of reinforced concrete, load bearing concrete block (where

available) or steel, fully protected from fire. No material shall be accepted, which supports combustion. 4.3 Roofing The majority of laboratory roofs will be flat construction. Water proofing shall consist of bitumen-based

felts, asphalt or similar material. Proposals for flat roof specifications shall demonstrate that requirements are clearly set out regarding watertightness, drainage, thermal and sound installation, fire precautions, maintenance and repair. In all cases, proposals for flat roof waterproofing shall also include the following:


GES B.11 of 26 Rev 0 1999

- Due to the prevailing intense solar radiation in the region, flat roofs shall be of the `inverted' type whereby loose-laid rigid insulation boards are placed over the waterproof membrane. Boards shall be ballasted with gravel and or paving flags. This will ensure that membranes are protected from deterioration arising from exposure to ultraviolet light and from roof traffic.

- All roofs shall be insulated with 50mm thickness of extruded, expanded polystyrene boards or

similar Owner approved material, polystyrene bead board shall not be acceptable. - Waterproofing shall be fully protected, at upstands, from sunlight by means of reflection gravel

and flashings. - Rainfall in the region is infrequent but often violent and designs shall allow for 3" (75mm) per

hour precipitation. Parapet walls shall have sufficient openings to ensure that roofs do not flood as a result of blockage to piped outlets. A slope of 1:80 towards the rainwater outlets shall be provided.

- Design proposals shall always include details of roof entries of piped services, demonstrating that

adequate waterproofing is allowed for. - Roof access doors shall always have thresholds a minimum of 150mm above the finished level,

i.e. with allowance for thickness of screeds, insulation and ballast. 4.4 Concrete Work Attention is drawn to the importance of adhering to good concrete practice in the prevailing climatic

conditions in the region. Vendor/Contractors shall conform to the recommendations and standards set out in GES Q.03 and GES Q.04, particularly with reference to hot weather conditions.

4.5 External Walling The most readily available and economic material for external walling will be rendered concrete

blockwork, although other materials may be acceptable, subject to Owner approval. Designs incorporating blockwork shall conform to the recommendations set out in GES Q.05. Laboratories designed with un-insulated single-skin blockwork walls will not be accepted. Where budgets allow, external block walling shall be insulated, or if cavity construction, incorporating insulation. Whatever the construction of external walling, designs shall incorporate external shading such as roof overhangs or other features to reduce the degree of direct exposure to sunlight.

4.6 Fire Resistance The design, materials and methods of construction of laboratories shall conform to accepted good practice.

The primary special characteristic required is for construction materials, components and finishes to be non-combustible throughout which shall produce little or no toxic fumes or heat when exposed to heat.

4.7 Thermal Stability Oil field laboratories require stable conditions for general testing. In addition, Refinery and Petrochemical

laboratories contain sensitive, expensive and sophisticated diagnostic equipment such as chromatographs and spectrograms, the accuracy of which require constant and precise conditions. These can only be achieved within building envelopes that are both thermally efficient and stable and free from vibrations. Generally, this may be achieved if permanent laboratories are housed in buildings of high thermal capacity. Construction of insulated load-bearing masonry or reinforced concrete frames, floors and roofs with concrete masonry walls, will satisfy both this criterion and the need for fire resistance. External walls shall be of insulated construction. Un-insulated external walls shall be avoided and designs should incorporate features which reduce the degree of exposure of external walls to direct sunlight, such as roof overhangs or shaded verandas.


GES B.11 of 26 Rev 0 1999

4.8 Location and Ground Level Laboratories shall, wherever possible, be located in non-hazardous areas, it is impracticable to ensure the

elimination of sources of ignition. They shall also preferably be free-standing buildings and shall not be contained within control buildings. For any laboratory building adjacent to hazardous areas, consideration shall be given to the requirement for blast resistance or protection. Generally the building shall be located far enough away from processing operations to allow for adequate dispersal of potentially hazardous vapour. Siting criteria should be based on the recommendations set out in IP Model Code of Practice: Part 15, or the Oil Insurance Association Bulletin No 631 (General Recommendations Spacing). Vendor/Contractors shall conform to the recommendations and standards set out in GES A.01.

4.9 Other Constructional Considerations The design of laboratories shall incorporate features which shall minimise the entry of Cockroaches, Flies

and Rodents in to the Lab spaces. The following precautions when taken during construction shall alleviate the pest problem. 4.9.1 Cockroaches, Black Beetles and Crickets Passage from room to room or floor to floor along pipe-runs, ducts and chases shall be prevented by

suitable sealing, intermediate lengths of ducts and chases shall be easily accessible. 4.9.2 Flies Well-fitted screens shall be provided for windows and ventilators. 4.9.3 Rodents (a) Service pipes and installation pipes - Wherever pipes and cables pass through a wall, they shall be

carried in sleeves and the space between the pipe and sleeve shall be effectively sealed. (b) Ducts and Chases - Ducts, chases and ventilating shafts shall be effectively sealed against the

entry of rats or mice. Where pipes are in ducts or chases passing through a wall or floor, they shall be embedded in rodent-proof material. Metal turnings and broken glass are useful for this purpose.

(c) Waste receivers - Waste receivers shall be of back-inlet type, any open channel shall be protected

by a grid to prevent the entry of rodents into the channel waste pipe. (d) Rain water down pipes - Down-pipes shall be protected against the entry of rodents and where

possible shall be connected to a back-inlet or similar gullies. The use of wire netting, or other obstruction to the outlets is not recommended.

(e) Hollow Walls - Hollow walls shall be sealed at the roof-plate level. There should be no access to

the cavity where service pipes, ducts, cables pass through or into the walls. (f) Footings - The base of all footings of outside walls and party walls shall be not less than 60cm

below the finished ground level to prevent access by burrowing, except where site concrete affords sufficient protection.

(g) Partitions, etc. - Joints between partitions and the main structure shall be effectively sealed. In the

construction within a building of a permanent structure or semi-permanent structure, precautions shall be taken to avoid harbourage in hollow partitions, or between the floor of the main building and the floor of the subsidiary structure or between their ceilings.

(h) Ventilating grids, screens, baffles and balloon pipe guards - Grids and other barriers shall restrict


GES B.11 of 26 Rev 0 1999

passage to a width of _" (10mm). Soil pipes and ventilating pipes shall always be provided with guard cages. Balloon pipe guards

should be resistant to corrosion. 5.0 COMPONENTS 5.1 Doors Vendor/Contractors shall conform to the recommendations and standards set out in GES B.17. 5.1.1 External Doors - External doors may be of timber, with glazed viewing panels, or alternative glazed anodised

aluminium frame. Doors shall be set into steel frames anchored into the structure. - External doors shall open outwards to counteract the effect of seasonal high wind. - External doors shall be fitted with effective, draught-excluding brushes and seals to ensure

weather-tightness and exclude wind borne sand, dust and the ingress of toxic gases. - Doors shall be heavy duty construction and shall be fitted with kicking plates to reduce damage

from trolleys etc.


GES B.11 of 26 Rev 0 1999

5.1.2 Internal Doors Internal doors generally shall be solid, 44mm thick, incorporating plaster board and providing at least 1

hour fire-resistance classification. Door leaves shall contain vision panels of wired or safety glass and be fitted at all edges with intumescent seals to resist the passage of smoke. They shall be equipped with kicking plates and overhead or similar closers. Storage rooms containing flammable materials shall be equipped with steel-faced doors or doors classified as giving 2 hours fire resistance.

5.2 Windows - Windows may be timber or anodised aluminium framed. - Windows shall be fitted with effective draught-excluding brushes and seals to ensure weather-

tightness and to exclude wind borne sand and dust. - Windows shall conform to the requirements of BS 6375. Vendor/Contractors shall conform with

the recommendations and standards set out in GES B.17. - Windows shall be kept to a functional minimum in non-hazardous areas. Where openable,

windows shall preferable be of sliding sashes and shall be fitted with integral fly screens. - For laboratories close to hazardous areas, windows shall be avoided on walls facing processing

plant. 5.3 Glazing Glazing shall generally be kept to a minimum to reduce solar heat gain, confined to those walls facing away

from direct sunlight or protected by shading. Windows are to have venetian blinds and curtains. Openable windows shall have insect screens.

5.4 Access and Security Various levels of security and selective access to laboratories may be required. Owner requirements shall

be confirmed at the initial design stages. 5.5 Joinery All timber, whether used as a finishing material or for general construction, shall be properly treated

against insect and fungal attack. 5.6 Ironmongery Requirements for ironmongery will vary, but Vendor/Contractors and Designers should seek Client

guidance for master key and suiting, together with security and restricted or selective access requirements. Any design submission should include schedules which clearly set out proposed standards of ironmongery in terms of:

- Quality - Finish - Means of Escape - Safety including fire resistance - Security 6.0 INTERNAL FINISHES


GES B.11 of 26 Rev 0 1999

6.1 Walls All walls shall be washable. For most applications, a washable acrylic polymer emulsion will be

acceptable. All toilet areas shall be tiled to door height with ceramic tiles. All washbasins and sinks shall be provided with tiled splashbacks. Generally, external walls of masonry construction should receive a reflective masonry paint finish or sand/cement rendering.

6.2 Floors The primary factors affecting the choice of floor finish in the working laboratory areas are durability, fire

behaviour, slip resistance and resistance to oils, solvents and acids. In addition, floor finishes shall be resistant to the creation of static electricity. Floor finishes shall therefore be restricted to the following:

6.2.1 Laboratories - Non-slip sheet PVC with welded joints, resilient backing and continuous skirtings. - Non-slip ceramic quarry tiles with covered skirtings. - Non-slip epoxy resin finishes. 6.2.2 Storage Areas for Solvents, Acids, Reference Fuels and Samples - Non-slip ceramic quarry tiles with covered skirtings. - Non-slip epoxy resins, especially selected for resistance to the above compounds. Specific mandatory safety details regarding floors in these areas include: - where laboratories are equipped with acid and electric battery stores, these shall be provided with

a vented and trapped floor drain to serve eyewash facilities and the washdown of electrolyte spills. - The spreading of electrolyte spills to other areas must be prevented by the use of bunded upstands

and changes of levels. 6.2.3 Offices and Corridors - Sheet PVC with resilient backing and skirting. 6.2.4 Tearooms, Toilets and Storage Areas - Quarry tiles. 6.3 Ceilings Proprietary suspended ceiling systems may be used in corridors, laboratory and office areas, provided that

dividing walls are taken to the structural slab level and fully sealed and that the compartmentalisation of the building is not compromised regarding fire resistance and the spread of smoke and flame. In general, textured paint finishes applied directly to the soffits of ceiling slabs will be acceptable where there is no central, ducted air-conditioning system. Storage areas may be left as fair-faced concrete.

7.0 SERVICES 7.1 Heating, Ventilation and Air-conditioning


GES B.11 of 26 Rev 0 1999
