never appeals against the decision of an adjudicator; they are the consideration of the dispute or difference as if no decision had been made by an adjudicator. If arbitration is chosen, then the reference is conducted under JCT the amended version of the Construction Industry Model Arbitration Rules published by the Society of Construction Arbitrators. Criticisms/alternatives Lawbuild has proposed a number of amendments to the JCT contract to protect the client further, with the top four being: to ensure the contractor posts a 10% bond to cover the costs of finding a replacement contractor if the contractor goes into liquidation, to ensure the contractor obtains building regulations certificates before practical completion, to ensure the contractor must accept design changes, and to ensure the employer can control the identities of the contractor's designers. One of the most common disputes around building contracts is with regard to the interpretation of failure to proceed regularly and diligently, and whether the contractor is able to make a claim for loss of profits after determination. In contrast in the US, building contracts can normally be terminated for convenience by the client, only paying for the work already done. The JCT makes no distinction between work completed by subcontractors and work completed by the contractor, so the client can end up paying the contractor for work certified and yet the contractor may not pay the subcontractor, for example through insolvency. It may then be hard to work with that subcontractor to complete the work. In contrast in some US states, monies due to subcontractors must be held in trust by the contractor. Alternative forms of building contract available include the Institution of Civil Engineers' Conditions, New Engineering Contract, FIDIC, GC/Works/I, Model Form, and IChemE Form. Publication of product liability report The Joint Contracts Tribunal in 1989 commissioned a report examining the legal distribution of liability for defective products in the construction industry. Published in 1993 as a book with the title Product liability in the construction industry (Palmer and McKendrick), it included an account of the tribunal's Origin and growth and a list of the seven chairman from 1931 to 1993, including Sydney Tatchell (1931-1956) and Sir Percy Thomas (1956-1960). It listed the constituent bodies of the tribunal at that time as the Royal Institute of British Architects, the Building Employers Confederation (formerly NFBTE, later Construction Confederation), the Royal Institution of Chartered Surveyors, the Association of
