For cost allocation questions for environmental and specific types of engineering cases, the main issues Clearwater can address are whether the past services or those services to be provided in the future reflect customary, reasonable and necessary tasks for the required scope of work.   Based on experience, training, education, 
Clearwater Group  has evaluated complex cost recovery cases as licensed professionals and general engineering and building contractors to examine invoices, daily field tickets, workplans, rate sheets, final reports, photographs and other documentary evidence.  Below are the type of questions that might be considered for cost allocation projects:  

  • Is the scope of work appropriate, reasonable and necessary for the goals of the project? 

  • Were similar methods customarily accepted by regulatory agencies and used by other professionals in the area?

  • In complex environmental cleanup cases with multiple parties, did the parties contribute equally over time to the contamination and were the contaminants of equal or different toxicity or level of recalcitrance in soil or groundwater (and consequently different cost to remove)?

  • Were the same contaminants released and processes performed on a property over time (such as a producing oil field), or were there several distinct contaminants from specific processes over time (such as an industrial region with multiple manufacturers)?

  • Were the cleanup costs appropriately divided among responsible parties?

  • Were all the consulting and contracting companies performing the work properly licensed?  

  • Were the all the workers, operators, competent persons, and field supervisors properly trained?

  • Are all reports correct and were they submitted on time to the regulatory agency to maintain compliance?  

  • Were there possible conflicts of interests in the services provided, and were those noted and disclosed?

  • Were the costs and level of effort appropriate for the scope of work, and how do they compare with standard reference tables from Means, Dodge or other available information?

  • What is the relationship between the property owner, the licensed professionals (consultants) and contractors?  

  • Were contractors and subcontractors appropriately trained for safety and hazmat work, which include medical surveillance, 40-hour OSHA safety training and annual refreshers?


  • Were all daily field tasks fully documented in writing and with photographs and logs?  

  • Do time sheets match billing tickets and invoices?


  • Was overtime pay paid properly according to state law?  

  • Do subcontractors have appropriate health and safety paperwork? 

  • Does the timeline of field and office tasks match the invoices? 

  • Were the tasks performed in a professional manner?

  • How close were the as-builts to the actual plans?

  • ​Was the level of care appropriate for the location and professional standards?

  • Were the change orders justified?
