Civil Engineering Design and Construction Administration Services for Timberlin Golf Course Bridges

The Berlin Public Building Commission (PBC) is assisting the Timberlin Golf Course in designing and replacing the six selected bridges. The PBC recognizes that funding may be phased over several years, so the pricing table reflects a per bridge approach after Preliminary Design. However, it is possible that the individual projects may be bundled, in which several bridges proceed to permitting, final design, and bidding/construction as one project.

With that in mind, proposers are encouraged to provide additional cost information reflecting a 2, 3 or 4-bridge approach after Preliminary Design, in which there should be cost efficiencies in handling multiple bridges as a single project. This information can be provided within the proposal, separate from the pricing table. The PBC’s approach to steps up to and including Preliminary Design is to complete these for all six (6) bridges. It should also be noted that hydrologic and hydraulic analyses should be focused on designing the bridges to minimize flooding and complying with permitting agency requirements – the PBC is not requesting a comprehensive watershed analysis of the golf course itself.

The six bridges proposed for replacement (Bridge Nos. 1, 2, 3, 6, 7 and 8 in Attachments A and B) were installed in the 1980's. Each bridge consists of a wooden deck made up of longitudinal planks affixed together and supported by wooden spans, covered with a 1-to-2-inch bituminous paved surface with wooden curbs. The bridge decks are supported at either end by concrete blocks, with crushed stone and riprap for scour and erosion protection. Please see attached documents which include more detailed individual bridge specifications.

The existing timber bridges (spans ranging from approximately 16 feet to 21 feet) will be replaced with reinforced concrete bridge systems designed to support golf carts and maintenance vehicles (H-5 loading for Bridge #s 1, 2, 3, & 6 and H-20 loading for Bridge #s 3 and 7).
