A Construction Estimator and Building Parts calculator

B-cal provides a suite of geometric and trigonomic functions essential to estimating construction and industry related jobs.

$ pip install b_cal

In  [1]: from b_cal.calculator import Calculator
Out [2]: cal = Calculator()

Find the hypothenuse of A triangle given its rise and base length.

[3] cal.hypothenuse(rise=8, run=14)

B-cal's Building Parts calculator currently estimates building foundations, walls, beams, columns, floors and roofs. B-cal returns its results in JSON format but can reproduce complete job estimate reports in various other file formats.

Estimate a concrete block wall given its length its height and thickness.

Calculate the length of a rafter given its rise and run

[4] cal.rafter(rise=1460, run=2901)

Calculate the area and hip length of a Roof Hip Section

In  [5]: cal.hip(rise=1469, run=2922, span=5843)

    {"area":9554709.81,
     "fascia": 5843,
     "hip": 4385.34,
     "pitch": 0.50273785,
     "rise": 1469,
     "run": 2922,
     "slope": 28.8,
     "span": 5843 }

b-cal returns a JSON object with key mapping to computed values of the roof segment, area in square units, fascia, hip, rise, run and span in run length units, pitch in radians and slope in degrees.

Calculate Area of Roof segment given the length of ridge, the length of the fascia, the run and rise distances.

In [7]: cal.roof_segment(ridge=3021, fascia=3021, rise=1469, run=2922,)
Out [8]: 
{'area':9554709.81,
'fascia': 3021,
'pitch': 0.50273785,
'rafter': 3270.48,
'ridge': 3021,
'rise': 1469,
'run': 2922,
'slope': 28.8}

B-cal defaults to the standard metric system of measurements but will accept imperial units if declared as a parameter argument eg: nuits='inch', units='sqrinch', units='inch2', units='ft', units='sqrft', units='f2'.
Note: If a units parameter is present b-cal ressets its measurement units for all calculations for the entire usage session.

B-cal can reproduce reports, in various file formats. A JSON file is produced with the save.to_json() Api save.to_pdf() produces a .pdf file save.to_xls() produces a .xls file save.to_txt() produces a .txt file and save.to_csv() produces a .csv file.
