As the results of a freedom of information request, the Tees Valley Combined Authority (TVCA) issued this list of groundworks.
N.B. One question that TVCA were unable to answer for all works has been removed. The question “Please supply any risk assessments carried out pertaining to these works” where the answer from TVCA for all groundworks was “Risk assessments pertaining to the works are prepared and by the construction contractor. Therefore, we do not hold this information”.
| Subject | What are the commencement and completion dates of each section of work / demolition covered in 13 to 16 | What were the exact works involved in 13 to 16 | Please supply details of all considerations pertaining to human and environmental risks carried out pre , during and post works of 13 to 16 inclusively |

| GE Blade Manufacturing Facility, South Bank | |||
| Construction of facility | This was to be a tenant development project that never proceeded. The site was taken over by SeAH Wind. The SeAH Wind development project dates are: Commencement: 01-Jul-22 Completion: 31-Dec-24 | The works involve the construction of a new monopile manufacturing facility by SeAH. This is not an STDC/Teesworks project. The land is being leased to SeAH for the purposes of the construction and operation of their facility. | STDC/Teesworks was not involved in the consenting and planning for the project. These are not matters for STDC/ Teesworks. This is a tenant project where all such assessments would be prepared by SeAH and their delivery supply chain. We are therefore not in possession of any relevant documents. |
| Key Risks to Delivery | With reference to number 17…please state what is meant by this paragraph and what were the mitigation processes and delivery issues | ||
| As the Board paper states, this relates to the risks to delivery to programme. The mitigating processes include the appointment of appropriately experienced project management consultants to manage delivery of the various projects such as are covered above, the development of robust project delivery schedules and the implementation of appropriate project controls. Delivery issues on construction projects typically include the availability of construction materials, particularly long-lead items, and their potential impact on schedule. On demolition projects, the primary delivery issue has been the availability of offsite routes to market for the safe disposal of recovered waste CoMAH substances from the cleaning and decontamination of assets prior to demolition. | |||
