Spa and Enclosure Building Scope of Work

Searching for a contractor to execute

 either PART A of this project which is excavating for and setting an in-ground fiberglass hot-tub and installing the plumbing and electric needed to run it; 

and/or PART B, which is building an enclosure for the hot-tub plus an extra room and breezeway connecting the structure to the main house - 400 sq. ft. total. 

Please contact Jaspen if you are interested in either or both parts as outlined below.

Initial estimates can be brief and generalized.

For formal proposals and contracts to be accepted, each section of this description, as it applies to the part of the project you are bidding on, needs to be included in your document >>using their corresponding numbers for easy reference.<<

Though plans are available, the list outlined here would take precedence

in bidding considerations.

Part A = #'s 1(A), 2, 3, 5-7, 22, 32-45 plus

preparation for #'s 10, 17, 18 possibly #'s 4, 8, 9 & foundation.

Part B = #'s 1(B), 3, 10-45, possibly #'s 4, 8, 9 & foundation.

This list is not exhaustive. The installation of the spa and the construction of the spa building (aka. "enclosure") will include everything that would establish the spa and building to be in good, sustainable working order and would closely replicate the picture provided in person by owner as much as possible.  This would include, but would not be limited to:

1. - Part A) Hot-tub installation to accommodate an in-ground fiberglass Viking Regal Spa provided by owner, plumbing and electric installation to run the spa, prep for future building enclosure; and/or Part B) Construct the hot-tub enclosure room, second room, and breezeway between spa room and main house. ~ 400 sq. ft. total.

We are ready for construction to begin immediately,

but our main priority is to arrange for affordable, quality work. 

Our goal is to begin as soon as this project would fit into your schedule.

Contractors are welcome to arrange for a site visit before submitting a quote,

but sending a general estimate based on the specs and documents described here

as a first step would greatly expedite the process.

Bids are expected to be within the current customary range

of $250 -$350 per square foot, or ideally, less 

especially with consideration of materials that owner may have already acquired.
