2 Design requirements
2.1 Location and characteristics of the land area, and situation of the work
a) Location and characteristics of the land area
Location: 290, Hung Vuong street, Vinh Trung ward, Hai Chau district, Da Nang city.
- Boundaries of the research area:

Location of Hai Chau district, Thanh Khe district, Hoa Minh ward - Lien Chieu district, Khue Trung, Hoa Tho Dong and Hoa Phat wards - Cam Le district

b) Current situation
- Con Market was built on an area of ​​13,714m², with the front of its block 1 on Hung Vuong street, a 3-story block on Ong Ich Khiem street and 9 level-4 blocks on the back.
+ Total market area: 13,714m².
+ Market building area: 12,644m², building density: 92.2%.
+ Total building area (office area excluded): 10,728m².
+ Commercial area: 5,334.3m², accounting for 49.7% of the building area.
- Con Market area is distributed unevenly to kiosks: each has the average total area of 4.5m²; but some are really small with the total area from 1.0m² to 1.5m² each.
- Business status (Year 2019)
+ Total household businesses: 2,011, of which 1,711 are permanent and approximately 300 are temporary.
+ Estimated total market, service and non-business fees receivable: VND 18,700 billion.
* General evaluation of Con Market situation
- Con Market was built on the occasion of the 10th Anniversary of the Liberation of Da Nang city (29 March 1985); it is more than 30 years since then so the technical infrastructure, auxiliary works, fire protection system have become patchwork and the environmental sanitation is degraded, no longer suitable nor able to guarantee market activities. Unified and fragmented product line planning makes it difficult to organize business activities and the environmental sanitation and hinders the construction of a food safety and commercial civilized market.
- Too high building density (92%), shortage of parking area and auxiliary works and inappropriate traffic access cause the market area to be frequently congested.
- The current small business space does not meet the needs of household businesses in need of premises for bulky and high-value products (according to the report on the results of a household business survey by Da Nang City Institute for Socio-Economic Development).
