To all the beneficiaries of Chennai (Ph II) project

Sub : Construction of Group Housing complex at Parathipattu, Poonamallee Road, Chennai

Sir/ Madam,

As you are aware that Chennai (Ph II) project is progressing and most of the structural works are already stands completed. We have also taken up the finishing works and accordingly the following revisions were made in the specifications of the following items :

i) As per the scheme & technical brochure the door frames are to be of pressed steel frames. In view of the feed back received with regard to the rusting of the frames, it was decided to provide factory made RCC door frames which are of better specification than pressed steel frame considering the cost involved.

ii) Considering the present trend as well as technical aspects, the specifications of flooring were reviewed. This is mainly due to the reasons that the availability of the marble of the same shade for such a mass housing project has become very difficult. Further mosaic tiles has become a real
obsolete specification and is not presentable in quality house. Considering the technical and aesthetic betterment, it was decided to provide 600 x 600 mm vitrified tiles of marble finish in the drawing and dining room as well as 400 x 400 mm off white ivory shade rectified tiles (Edge cut ceramic tiles) in all other rooms. It is to inform you that the above changes are technically superior than the original specifications. Further it is to inform you that the colour scheme adopted in drawing/ dining room is of marble finish which shall resemble to marble flooring. The off-white colour in all other rooms are considered to give a matching look.

2. A comparison between mosaic/ marble flooring and vitrified/ rectified flooring is placed in Annexure A.

Yours faithfully,
