B. Play Areas

1. The Play Areas shall have all play equipment appropriately staked to allow for the proper protective zones that are required around each piece of the play equipment. The Contractor shall coordinate this portion of the work with the vendor manufacturer representatives to insure that the layout between the various equipment pieces is correct. The Contractor, at his expense, is responsible for any final revisions to the AutoCAD drawings based upon the various equipment manufacturers used for the project. It is anticipated that there could be more than one company’s equipment being used on the site. Coordination between the

01400 - 4 various suppliers is at the sole expense of the Contractor.

2. No additional costs of any kind will be allowed because the selected equipment might require additional space and thus require additional excavation and protective surfacing underneath the equipment.

C. Other Park Survey Work

1. Various site amenities will need to be located and staked per the drawings.

2. If the contract includes trees, the City Represenatitive will work with the

Contractor in the staking of all locations for the trees. The Contractor shall provide the stakes and labor to place them.
