9 In June 2006, Mr Osborne says that he and his wife noticed that the cracking in the driveway had worsened.
10 On 9 July 2006, Mr and Mrs Osborne wrote a letter to Mr and Mrs Hook which identified the areas about which they were concerned as being:
o the driveway near the Liquidambar;
o the driveway near to a drain; and
o the paved area adjacent to the house.
11 Three photographs were appended to that letter. The letter foreshadowed seeking investigation by an arborist and obtaining specialist advice from the arborist. It was, at that stage, also foreshadowed that a copy of the arborist's report would be provided to the Hooks. The letter further foreshadowed a variety of elements proposed to be undertaken:
o obtaining permission from the Council to sever the roots;
o installing preventative barriers;
o repairing damage to the driveway and the paved area; and
o seeking compensation to cover all costs.
12 On 16 July 2006, the Hooks replied indicating that they would respond in detail after receiving material relating to the identification matters being undertaken.
13 On 21 July 2006, Mr Hartley, the Osbornes' arborist, inspects the property.
14 On 26 July 2006, Mr Brand, the Osborne's consulting engineer, makes an inspection.
15 On 27 July, Mr Brand prepares his report.
16 On 1 August 2006, the Osbornes write to the Hooks:
o advising the arborist has identified the Liquidambar as the cause of the cracking;
o confirming that they propose to apply to sever the roots;
o advising that they were proceeding on an extensive holiday from 7 August; and
o advising that a report would be provided when it was available.
17 Importantly, this letter made no mention of any timetable for rectification of the driveway.
18 By quotation dated 1 August, A. V. Maintenance provides the Osbornes with a quote for approximately $9,000 for rectification of what we accept is the relevant section of the driveway (subject to a minor calculation change concerning a concrete pump - which change does not detain us at this time).
19 On 7 August, the Osbornes leave for their holidays.
20 On 11 August, Mr Hartley prepares his report.
21 On 15 August, the Osbornes' solicitor, Mr Bricknell, writes to the Hooks doing a number of things (including service of Mr Hartley's report and the A. V. Maintenance quote). Importantly, toward the end of the letter, he says the following:
Rectification works are due to commence on 18 September 2006.
Please advise us at your earliest convenience if you wish to arrange an inspection of the tree roots. Please note that the commencement of the rectification works will not be postponed in the event that you have not arranged an inspection of the roots prior to that date.
22 On 18 August, the Osbornes' solicitor writes to the Hooks serving a copy of the Osbornes' structural engineer's report dated 27 July.
23 On 31 August, the Hooks' arborist undertakes an inspection of the driveway.
