Mohali (Punjabi: ਮੋਹਾਲੀ, Hindi: मोहाली, mōhālī) is a city adjacent to Chandigarh, 18th District in Punjab, India. It is officially named after the eldest son of Guru Gobind Singh, Sahibzada Ajit Singh (SAS Nagar, or "House of Sahibzada Ajit Singh"). It along with Chandigarh and Panchkula form a part of the Chandigarh Tricity or Chandigarh Capital Region. It was earlier a part of the Rupnagar District, and was carved out into a separate district in the recent years.

Background
Mohali was conceived after the trifurcation of Punjab and its capital Chandigarh becoming a Union Territory in late 1966. Today, Mohali and Chandigarh are contiguous areas with only the boundary of Punjab and UT of Chandigarh dividing this area. The original plan of Mohali is in fact a mere extension of the road and design system of Chandigarh without any unique planning. The development earlier was only till Phase VII. The development of sectors and phases from Phase 8 onwards started in late 1980s, and the city got its own bus stand in Phase 8 in mid 1990s. In 2006, Mohali's population is near 200,000, approximately 1/5 of Chandigarh's. The region has been targeted by an increasing number of outsourcing IT companies, who look to capitalize on the rich investment opportunities the city offers.
Mohali and Panchkula are under the consideration of Punjab and now a days Mohali is a separate district of punjab.

Location
Mohali is located to the West of Chandigarh. It is almost a continuation of the Chandigarh city. To its north is Rupnagar district. To its south are Fatehgarh Sahib and Patiala. Due to fast urban growth, Mohali has almost merged into the Chandigarh city.

City Design
Following the success of Chandigarh's sector design, Mohali was similarly planned into identical 800 X 1200 m sectors. Many have yet to be fully developed, as is the case of sector 62, which is earmarked for a future commercial City Centre. Its proximity to the PCA Stadium, as well as unrivaled transportation links to Chandigarh make it a suitable choice.
The recent Master Plan of Mohali has been recently extended up to 114 sectors.
The iconic PUDA Bhawan-official headquarters of the Punjab Urban Planning and Development Authority, initiated by KBS Sidhu, an IAS officer, signifies the towering role of PUDA vis-a-vis Mohali. Now, PUDA's functions of planning and urban development have been transferred to the Greater Mohali Area Development Authority (GMADA); initially DC Mohali had been named as its Chief Administrator, but now a separate and full-time IAS officer has been so appointed.

Cricket Stadium
In 1992, the Punjab Cricket Association (PCA) unveiled a plan to build a state of the art facility complete with a separate practise ground - to be built in a swampy area in Mohali . The PCA invested heavily in the ground, a swimming pool, health club, tennis court, library, restaurant, and bar and outdoor & indoor cricket practice nets were incorporated into the plans.
Most of the Punjab-based national cricketers train in Mohali, including Yuvraj Singh, Harbhajan Singh, Dinesh Mongia, Manpreet Gony and Punjab cricket team.



Corporate Investment
While Mohali houses many state-local companies like PTL (Punjab Tractor Limited), ICI Paints, and the Godrej Group, its reputation as a home for large, multinational corporations is growing.


Quark, Mohali
Infosys, the well-known Indian IT services major, had a development center in Mohali, which has now moved to Chandigarh Technology Park. Global tech giants like Dell, Quark, Philips, Sebiz Infotech, SCL (Semiconductor Complex Limited), and PUNCOM have followed. Denver-based Quark has created the $500M, 46-acre (190,000 m2) QuarkCity in Mohali, complete with a residential complex comprising 30% of the 'city'; the shopping, entertainment, medical, and educational district consume another 10%. It is expected to generate 25,000 direct, and 100,000 indirect jobs.
QuarkCity is a 51-acre (210,000 m2), multi-use development that includes a Special Economic Zone (SEZ). QuarkCity is located in the district of Mohali, Punjab, within the extended grid of Le Corbusier’s modern city of Chandigarh, 265 km (166 miles) north of India’s capital city of New Delhi.
