The Delaware Board of Education has approved a change order that will decrease the costs of the construction at Schultz Elementary School.

School officials said the orders are made to adjust for the actual expenses of the work that occurs during a project.

The original contract sum for the project was $4,140,845.70 and the decrease brought the contract sum to a total of $4,048,048.73. The changes accounted for work on a fire alarm that was removed, costs for added services and cash allowances that remained at the conclusion of the project.

School officials said these types of change orders are standard when a construction project is completed. The money was not paid out in the first place and will remain in the school district’s bond fund.

The Schultz construction project added two new wings of classrooms to accommodate students from kindergarten through fifth grade — for when the district transitions to a K-5 model next year.

The school board Monday also approved a number of staffing changes.

The board accepted the resignation of Diane Levings, a school-age child care employee at Schultz.

The board also approved the hiring of Risa Owen, a technology specialist at Schultz; Lisa Toombs, a school nurse at Schultz and Woodward elementaries; and Catherine Davis and Dawna Malisiak, classified substitutes.

The board approved supplemental contracts for several employees at Hayes High and Dempsey Middle schools for the wrestling and basketball teams.
