The job was a challenging one considering all of the construction constraints. The building operating staff is equally impressed with the professionalism and expediency that you and your people exhibited during the project. They have expressed their satisfaction with the job as a whole and have indicated that when another project of a similar nature is considered that you should definitely be the contractor of choice. I agree. Again, thank you for a job well done.”
