1 GRIHA Site Visit Due Diligence II Project Name : Project Code: Location: 2010HH46 Indira Paryavaran Bhawan Jor Bagh, New Delhi Date: 16 th May 2013 Construction Stage: ADaRSH representatives: Construction is mostly complete. Finishing work is going on. Solar PVs have been installed. Landscaping work is yet to begin. Ms Chitrangada Bisht Mr Akashdeep I. SITE PLANNING: Criteria Compliance on site Observations C-02 Preserve and protect landscape during construction/compensatory depository forestation. Proper timing of construction and staging of construction Soil erosion channels and sedimentation tanks built on site during construction Partly All buildings were above ground before the onset of monsoons. PERT Chart and other related records were checked on Site. Ref. Image 1. The landscaping work has not begun on site. The earth air tunnel has already been installed. Soil erosion channels have not been dug on site and water logging was noted. Ref. Image 2 Action to be taken: Soil erosion channels on site to be immediately cleaned, cleared and to be maintained for proper functioning. Sedimentation Tanks to be made at all low lying areas at site and connected through these channels. Trees on site have been protected Partly Some trees have been protected on site whereas some have not. Ref. Image 3, 4 & 11. Action to be taken: Ensure all existing trees on site to be duly protected by suitable means. C-03 Soil conservation Top soil has been stored and stabilized Measures have been taken for maintaining fertility of top soil C-07 Plan utilities efficiently and optimize on-site circulation Top Soil preserved and stored and mulched. Ref. Image 5 Grass has been planted on the top soil to maintain fertility. Ref. Image 5 Aggregated utility corridors are used Aggregate utility corridors have been constructed. Services drawings were checked on the site Planning of services along with the vehicular / pedestrian paths/existing utility corridors Same as above.

2 II. BUILDING DESIGN OPTIMIZATION Criteria Compliance on site C-13 Optimize building design to reduce conventional energy demand Observations WWR ratio and SHGC as per ECBC Could not be verified at Site. The project team confirmed that WWR is well within the GRIHA requirement. Energy efficient glazing (DGU) has been installed; however the SHGC calculation was not available. Ref. Image 17 Action to be taken: Energy consultants to ensure analysis data is being adhered to and all decisions at site are in accordance to the analysis. C-14 Optimize energy performance of building within specified comfort limits ECBC mandatory Requirements All ECBC requirements could not be verified on site. To be ensured that following compliance are met: SHGC for all windows meet ECBC requirements. Transformers installed meet the ECBC requirement. Lighting controls for spaces are as per ECBC requirement. Motors/pumps meet the ECBC requirements. HVAC systems meet the required COP as per ARI and Indian conditions. III. WATER, WASTE-WATER AND SOLID-WASTE MANAGEMENT Criteria C-10 Reduce landscape water demand Native trees planted on site Installation of efficient irrigation systems Compliance on site Could not be verified at this stage. Could not be verified at this stage C-12 Efficient water use during construction Measures have been taken on site to reduce use of potable water during construction C-22 Reduction in waste during construction Observations Landscaping work has not yet begun on site. Action to be taken: Project Team to ensure compliance. Same as above. Project team assured that gunny bags and ponding on slabs have been done for curing. Admixtures were added to RMC to reduce water demand for curing. Action to be taken: Project Team to provide photographic evidence for ponding of roof structures and use of gunny bags. Measures have been taken on site to reduce waste during construction No Site Management plan was not being adhered to. Waste Management provisions to store, segregate and recycle construction waste had been made only for some parts of the site. Ref. Image 4, 10 & 11.

3 Action to be taken: Site management plan should clearly define all areas for waste storage and segregation and should be followed at all times. IV. SUSTAINABLE BUILDING MATERIAL & CONSTRUCTION TECHNOLOGY Criteria Compliance on site C-15 Utilization of fly ash in the building structure PPC is being used in the building s structural system Additional fly ash being added on site for application in the building s structural system Use of fly ash bricks or AAC blocks or other bricks with BIS recommended waste content Use of PPC in plaster and masonry mortar Additional fly ash being mixed on site for use in mortar No No C-16 Reduction in embodied energy of the building Observations All construction till now has been with PPC and same was checked in Batch Mix Reports. Additional fly-ash is not being mixed on site. 100% walling using light weight AAC blocks. Fly Ash Bricks are being used for Internal Walls. Ref. Image 9. All construction has been done using PPC. PPC was used for all construction. Low-energy structural systems being incorporated on site Low-energy walling materials being adopted on site C-17 Low energy materials Low-energy material use in false ceiling/partitions/subassembly/panelling/in-built furniture No None AAC blocks have been used. Use of low-energy flooring Partly Low energy finish terrazzo used in corridors and vitrified tiles in all other areas. Use of low-energy materials in doors, windows and their frames V. HEALTH, WELL BEING & ENVIRONMENTAL QUALITY: Criteria Compliance on site C-08 Safety & sanitation facilities for workers Observations All construction workers are wearing hard-hats and safety boots Proper safety facilities have been provided for the construction workers like safety harnesses, safety nets, gloves etc. depending upon activity No Partly Some construction workers were wearing hard hats and none was wearing safety boots. Ref. Image 12 & 13. Action to be taken: Project team to ensure that construction workers wear safety gear at all times on the construction site. Safety harnesses were provided to all Labourers working at heights and safety nets were no more installed since the work on the upper floors was complete.

4 Clean drinking water is available to construction workers Clean and hygienic toilets are provided to the construction workers Labour accommodation is clean, hygienic and comfortable (daylight and ventilation) No No C-09 Reduce air pollution during construction Project team stated that clean drinking water was provided to the workers. However, they were found to be taking drinking water from a nearby well. Ref. Image 13. Action to be taken: Project team is recommended to install more drinking water points at suitable places. Worker toilets were not in good condition and workers were not using the provided facilities. Ref. Image 14. Action to be taken: The project team has been asked to get the facilities cleaned on a regular basis. Labour accommodations were satisfactory. A crèche was provided for the children of the construction workers. Ref. Image 15. Sufficient measures have been taken on site to control air pollution C-34 Innovation Innovation points attempted on site Partly Could not be verified at this stage. Site boundary has been erected to a height of 7 feet. Water was sprinkled on roadways. There was no wheel washing facility at site. Action to be taken: Wheel washing facility should be erected at site. Provisions should be made to ensure that all dusty materials are covered while stored. Use of GRIHA logo at site: GRIHA Logo is not being used anywhere at prominent location at Site. High Resolution GRIHA Logo is attached with this report, to be put up at a prominent location at site.

19 Project was only partly compliant with the following mandatory criterion under GRIHA: 1. Criterion 2: Preserve and protect landscape during construction/compensatory depository forestation 2. Criterion 8: Safety & sanitation facilities for workers 3. Criterion 9: Reduce air pollution during construction Please note: Non-Compliance with mandatory criterion under GRIHA shall render the project ineligible for GRIHA Rating. Project is requested to submit a compliance report within 15 days from the date of receipt of the report. All the observations and actions to be taken were communicated to the project team during the site visit conducted by ADaRSH. Report prepared by ADaRSH
