We decided to chose DB or design build for this assignment

The Waller family in Auckland recently sold their family house in Remuera for about \$8.5Milion to move to a coastal town on the west coast of the North Island. They bought a 15,000 square meter section in New Plymouth to build a house (rural and lifestyle) for themselves and build a small hotel for investment. New Plymouth is a major city in the Taranaki region that is known for its sunny weather, art galleries, and beautiful landscapes. The Waller family believes these attributes could attract tourists once NZ borders are opened. Especially now that New Plymouth is becoming a popular place for people to live. Their objectives are to build a sustainable rural lifestyle home with a budget of $2.3 Million with a top Homestar rating. Then as an investment, they would build a two-story level 10-bedroom hotel in the 10,000 Square meters of the section. The 10,000 square meter will include a parking lot for the hotel visitors. Both projects are to have a high standard of architectural design qualities and will be required to be delivered within strict timelines and budget once agreed. They want both projects to be well built with few if any defects on completion. They have set aside 5.2 Million dollars for the construction of the hotel. The family is keen on moving into their new home, so they have set a very tight timeline for the projects to be completed within a year from the date a contract is signed. The family worries that the timeline could be difficult to achieve considering the current lead times for building materials like Gib board and cladding. These material shortages because of Covid could delay the project and increase the project's final cost. They plan to use a construction company to take on both projects (their home and investment property). A good option for the family is to build both the hotel and the family house concurrently. With this arrangement, the contractor will be able to maximise the use of their resources. The key to achieving a high Homestar rating are: - 93% efficient Heat recovery ventilation - Airtightness and vapour control layer - Insulation double code requirements - All glass is low E, low E Max, and Argon gas filled - Thermally broken frames - Sustainable materials include locally sourced, FSC-certified timber for decking and cladding. - Energy and water-efficient appliances and fixtures - Eco-approved sealants and paints - Rooftop rainwater harvesting - 80% of construction waste is diverted from landfills. Q3. Provide recommendations with reasons as to which method you consider best meets the needs of the Waller family (five recommendations) (10 marks)
