vi. Impact of selected building materials. Address the environmental impacts associated with the life cycle of building materials.

Light and views: The design should maximize natural light, views, and access to the outdoors, as appropriate.

i. Access to natural light should be achieved. Examples include windows at the ends of corridors, skylights into deep areas of the building in highly trafficked areas, transoms, and door sidelights.

II. It should provide a garden or other controlled exterior space, accessible to building occupants. Setting and organization of the building should respond to and prioritize unique natural views and other natural site features.

Clarity of access (way-finding) i. Entry points to the labs should be clearly defined from all major exterior circulation

nodes. ii. Clearly visible and understandable signage and visual landmarks for orientation

should be provided. iii. Boundaries between public and private areas should be well marked, and clearly

distinguished. iv. A system of interior "landmarks" should be developed to aid occupants in cognitive

understanding of destinations. These may include water features, major art, distinctive color, or decorative treatments at major decision points in the building. These features should attempt to involve tactile, auditory and language cues, as well as visual recognition.



Control of Environment:

i. Every effort should be made to allow individual control over as many elements of the environment as possible and reasonable, including but not limited to temperature, lighting, and privacy.

ii. Building design should address individual contra! over the thermal environment, through carefully considered zoning of mechanical systems.

Privacy: Lounges, Rest rooms to be provided at all locations.

Safety and Security: i. Attention should be given to balancing readily accessible and visible external access

points to the facility with the ability to control and secure all access points in the event of an emergency. Factors such as adequate exterior lighting in parking lots and entry points to the facility, and appropriate reception/security services are essential to ensuring a safe environment.

ii. Since the strict control of access to a lab facility is neither possible nor appropriate, safety within the facility should also be addressed through the design of circulation paths and functional relationships.

iii. Provisions for securing the personal belongings of staff, visitors should be addressed. iv. The physical environment should be designed to support the overall safety and security

policies and protocols of the institution. Finishes: i. In any design project, the selection of a color palette should be based upon many factors,

including the building population, anticipated behavior in the space, time of encounter and level of stress. The color palette selected should be suitable and appropriate for the specific environment, taking into account the specific activities conducted in that environment.

ii. Finishes and color palettes should respond to the geographic location of the facility, taking into account climate and light, regional responses to color, and the cultural characteristics of the community served.

iii. The effect on staff/visitors of materials, colors, textures, and patterns shall be considered in the overall planning and design of the facility. Maintenance and performance shall be considered when selecting these items.



Water features: i. Open decorative water features such as fountains etc.

Where props rest on natural or filled up ground, to avoid any settlement, the soil should be thoroughly compacted and bases of props shall be of sufficient size as to restrict the bearing pressure on the ground to ST/sqm.

iii. All formwork erected shaif be approved by the Engineer before concreting is started. iv. Formwork should be removed carefully so as to prevent damage to the concrete. Wooden

wedges only shall be used between the concrete surface and the form if necessary while removal. Metal wedges, bars or tools shall not be used for this purpose. Any concrete damaged in the process shall be repaired in accordance with the provisions of concrete specifications.

v. Immediately after the forms are removed, they shall be cleaned with jet of water and a soft brush before they are reused.

4. Steel Reinforcement Prior to the delivery of reinforcement steel required, the contractor shall submit the following to the Engineer for review. (a) Certified copies of mill tests reports including chemical analysis and physical

properties as required by the applicable Indian standards for each consignment of steel.

(b) Where such mill certificates are not available or if the Engineer feels to subsequent conformance of the mill test reports, the Contractor shall employ an approved testing laboratory to perform the required tests and chemical analysis at his cost.

i. Steel reinforcement specifications (a) Mild Steel of Grade 1 tested quality conforming to IS: 432 part 1 (b) High strength deformed steel bars of tested quality conforming to IS: 1786 (c) Hard drawn steel wire fabric conforming to IS: 1566 (d) Thermo mechanically treated bars conforming to relevant IS code i. All steel shall be procured from original producers and no rolled steel shall be

incorporated in the work unless permitted by the Engineer. ii. Only new steel shall be delivered to the site and shall be free from any mill scale, lose

rust, grease, oil, paint or any other deleterious material which reduces or destroys bond.

iii. Defective, brittle and burnt bars shall be discarded and not included in the work. Cracked end of bars shall be discarded.

iv. Binding wire shall be annealed steel wire conforming to IS: 280 and minimum 18 gauge.

v. Welding Electrodes shall be ordinary mild steel grade electrodes conforming to IS 814



and shall be of best quality approved by the Engineer.
